Summary of Significant Accounting Policies |
2. Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, or U.S. GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted, and accordingly the balance sheet as of December 31, 2018, and related disclosures, have been derived from the audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for the fair statement of the Company’s condensed consolidated financial information. Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to current period presentation. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019 or for any other interim period or for any other future year. The accompanying interim unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited financial statements and the related notes thereto for the year ended December 31, 2018 included in the Company’s annual report on Form 10-K, filed with the SEC on March 4, 2019. Revision of Previously Reported Financial Information During the preparation of the Company’s quarterly report on Form 10-Q for the quarter ended March 31, 2019, the Company identified an error in the presentation of the changes in the allowance for doubtful accounts and contractual allowance disclosures in its Quarterly reports for the periods ended March 31, June 30 and September 30, 2018. During these quarters, a portion of the allowance for contractual adjustments was incorrectly presented as a provision for doubtful accounts. The Company concluded that the amounts were not material to any of its previously issued condensed consolidated financial statements. The error impacted the disclosures but did not impact the Company’s condensed consolidated balance sheets, statements of operations or statements of cash flows. The error did not impact the disclosures in the previously issued consolidated financial statements in the Form 10-K for the year ended December 31, 2018. The following tables presents the impact of the revision on the changes in the contractual allowance and allowance for doubtful accounts balances for the interim periods in the year ended December 31, 2018 (in thousands):
Note that the above adjustments did not result in any changes to the Company’s total receivables-related reserves for the periods in the table above.
(1) For the three months ended March 31, 2018, the allowance for contractual adjustments was increased by $1.4 million and the provision for doubtful accounts was reduced by the same amount. (2) For the six months ended June 30, 2018, the allowance for contractual adjustments was increased by $2.0 million and the provision for doubtful accounts was reduced by the same amount. (3) For the nine months ended September 31, 2018, the allowance for contractual adjustments was increased by $2.7 million and the provision for doubtful accounts was reduced by the same amount. In addition, in the contractual allowances table, contractual adjustments were increased by $0.6 million and the allowance for contractual adjustments was reduced by the same amount. Accounts Receivable, Allowance for Doubtful Accounts and Contractual Allowance Accounts receivable consists of amounts due to the Company from institutions, third-party payors, government and commercial payors and their related patients, as a result of the Company's normal business activities. Accounts receivable is reported on the condensed consolidated balance sheets net of an estimated allowance for doubtful accounts and a contractual allowance. The Company establishes an allowance for doubtful accounts for estimated uncollectible receivables based on its historical experience and recognizes the provision as a component of selling, general and administrative expenses. The Company establishes a contractual allowance when it estimates that consideration to be received will be lower than the contracted rate based on its historical experience and recognizes the provision as a reduction to revenue. The following table presents the changes in the allowance for doubtful accounts (in thousands):
The following table presents the changes in the contractual allowance (in thousands):
The following table presents the impact of allowance for doubtful accounts and contractual allowance on accounts receivable (in thousands):
The Company reviews and updates its estimates for the allowances for doubtful accounts and contractual allowance periodically to reflect its experience regarding historical collections. If management were to make different judgments or utilize different estimates in the allowances for doubtful accounts and contractual allowance, differences in the amount of reported selling, general and administrative expenses and revenue could result, respectively. Concentrations of Risk Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. Cash, cash equivalents, and investments are deposited in financial institutions which, at times may be in excess of federally insured limits. Cash equivalents are invested in highly rated money market funds. The Company invests in a variety of financial instruments, such as, but not limited to, United States Government securities, corporate notes, commercial paper and, by policy, limits the amount of credit exposure with any one financial institution or commercial issuer. The Company has not experienced any material losses on its deposits of cash and cash equivalents or investments. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of customers comprising the Company’s customer base and their dispersion across many geographies. The Company does not require collateral. The Company records an allowance for doubtful accounts when it becomes probable that a receivable will not be collected. Federal government agencies, including Centers for Medicare and Medicaid Services (“CMS”) and the military, accounted for approximately 35% and 37% of the Company’s revenue for the three months ended March 31, 2019 and 2018, respectively. Accounts receivable related to federal government agencies accounted for 19% and 18% at March 31, 2019 and December 31, 2018, respectively. Revenue Recognition The Company’s revenue is generated primarily from the provision of its cardiac rhythm monitoring service, the Zio XT service. The Zio XT is a cardiac rhythm monitoring service that has a patient wear period of up to 14 days and is billable when the monitoring reports are delivered to the healthcare provider, which is also when the service is complete and the Company recognizes revenue. The time from when the patient has the Zio XT device applied to the time the report is posted is generally around 20 days. The Company accounts for contract revenue with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company's revenue is measured based on consideration specified in the contract with each customer. A unique aspect of healthcare is the involvement of multiple parties to the service transaction. In addition to the patient, often a third-party, for example a commercial or governmental payor or healthcare institution, like a hospital or clinic, will pay the Company for some or all of the service on the patient’s behalf. Separate contractual arrangements exist between the Company and third-party payors that establish amounts the third-party payor will pay on behalf of a patient for covered services rendered and should be considered in determining collectability and the transaction price for services provided to a patient covered by that third-party payor.
The Company recognizes revenue on an accrual basis based on estimates of the amount that will ultimately be realized. These estimates require significant judgment by management. In determining the amount to recognize for a delivered report, the Company considers factors such as claim payment history from both payors and patient out-of-pocket costs, payor coverage, whether there is a contract between the payor or healthcare institution and the Company, historical amount received for the service, and any current developments or changes that could impact reimbursement and healthcare institution payments.
A summary of the payment arrangements with third-party payors and healthcare institutions is as follows:
The Company is utilizing the portfolio approach practical expedient under ASC 606 for revenue recognition. The Company accounts for the contracts within each portfolio as a collective group, rather than individual contracts. Based on history with these portfolios and the similar nature and characteristics of the patients within each portfolio, the Company has concluded that the financial statement effects are not materially different than if accounting for revenue on a contract-by-contract basis.
For the healthcare institution, the Company has historical experience of collecting substantially all of the negotiated contractual rates and determined at contract inception that these customers, and or their related third-party payor that pays the Company on their behalf, have the intention and ability to pay the promised consideration. As such, the Company is not providing an implicit price concession but, rather, has chosen to accept the risk of default, and any subsequent impairment of the related receivable are recorded as bad debt expense.
For contracted and CMS portfolios, the Company is providing an implicit price concession because, while the Company has a contract with the underlying payor, the Company expects to accept a lower amount of consideration when claims are adjudicated and allowable claims are determined by the commercial payor. The implicit price concession is recorded as variable consideration to the transaction price and recorded as an adjustment to revenue as a contractual allowance. Historical cash collection indicates that it is probable that substantially all of the allowable claim amount will be received, and hence this amount is recorded as revenue. Any subsequent impairment of the related receivable is recorded as bad debt expense.
For non-contracted portfolios, the Company is providing an implicit price concession because the Company does not have a contract with the underlying payor, the result of which requires the Company to estimate transaction price based on historical cash collections utilizing the expected value method. Subsequent adjustments to the transaction price are recorded as an adjustment to revenue and not as bad debt expense. Disaggregation of Revenue The Company disaggregates revenue from contracts with customers by payor type. The Company believes these categories aggregate the payor types by nature, amount, timing and uncertainty of its revenue streams. Disaggregated revenue by payor type and major service line for the three months ended March 31, 2019 was as follows (in thousands):
Contract Liabilities ASC 606 requires an entity to present a revenue contract as a contract liability when the Company has an obligation to transfer goods or services to a customer for which the Company has received consideration from the customer, or an amount of consideration from the customer is due and unconditional (whichever is earlier). Certain of the Company’s customers pay the Company directly for the Zio XT service upon shipment of devices. Such advance payments, or contract liabilities are recorded as deferred revenue on the Condensed Consolidated Balance Sheets and revenue is recognized when reports are delivered to physicians. Total revenue recognized during each of the three months ended March 31, 2019 and March 31, 2018 that was included in the contract liability balance at the beginning of each respective period was $1.2 million. Contract Costs Under ASC 340, the incremental costs of obtaining a contract with a customer are recognized as an asset. Incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained.
The Company’s current commission programs are considered incremental. However, as a practical expedient, ASC 340 permits the Company to immediately expense contract acquisition costs, as the asset that would have resulted from capitalizing these costs will be amortized in one year or less.
Leases
Identifying a lease
The Company determines whether a contract contains a lease at the inception of a contract. If the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration, the Company considers the contract to contain a lease. The Company determines whether a contract conveys the right to control the use of an identified asset for a period of time if the contract contains both of the following terms:
Discount Rate for leases On January 1, 2019, the rate implicit in the Company’s leases was not readily determinable. As such, the Company used its incremental borrowing rate to calculate its right-of-use assets and lease liabilities. The Company determined the appropriate incremental borrowing rate by utilizing the interest rate obtained in connection with the Third Amended and Restated Loan and Security Agreement with Silicon Valley Bank which was finalized on October 23, 2018. Lease term The lease term is generally the minimum noncancelable period of each lease. The Company does not include option periods in determining the right-of-use asset and right-of-use liability unless it is reasonably certain that the Company will exercise the option at inception or when a triggering event occurs. As of March 31, 2019, the Company did not include any options to renew in the lease terms of its current lease portfolio. Recently Adopted Accounting Guidance In February 2016, the Financing Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (“Topic 842”), which requires lessees to recognize lease liabilities and corresponding right-of-use assets on the consolidated balance sheet for all leases. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset and, for operating leases, the lessee would recognize a straight-line lease expense. Topic 842 also changes the definition of a lease and expands the disclosure requirements of lease arrangements. The Company has no embedded leases with suppliers. Upon adoption of Topic 842 on January 1, 2019 using the modified retrospective method, the Company recognized right-of-use assets of $10.4 million and lease liabilities of $10.2 million. There was no cumulative-effect adjustment recorded on January 1, 2019. The Company adopted the following practical expedients allowed under Topic 842:

Fair Value Measurements |
4. Fair Value Measurements The Company discloses and recognizes the fair value of its assets and liabilities using a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The hierarchy gives the highest priority to valuations based upon unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to valuations based upon unobservable inputs that are significant to the valuation (Level 3 measurements). The guidance establishes three levels of the fair value hierarchy as follows: Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 - Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3 - Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. The corporate notes, commercial paper and government securities are classified as Level 2 as they were valued based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets. The fair value of the Company’s outstanding interest-bearing obligations is estimated using the net present value of the payments, discounted at an interest rate that is consistent with market interest rates, which is a Level 2 input. The carrying amount and the estimated fair value of the Company’s outstanding interest-bearing obligations at March 31, 2019 are $34.9 million and $34.9 million, respectively. The carrying amount and the estimated fair value of the Company’s outstanding interest-bearing obligations at December 31, 2018 were $34.9 million and $34.9 million, respectively. The Company had no transfers between levels of the fair value hierarchy of its assets measured at fair value. The following table presents the fair value of the Company’s financial assets and liabilities determined using the inputs defined above (amounts in thousands).

6. Commitments and Contingencies
Lease Arrangements
The Company leases office, manufacturing, and clinical centers under non-cancelable operating leases which expire on various dates through 2031. These leases generally contain scheduled rent increases or escalation clauses and renewal options. Operating lease right-of-use assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The operating lease right-of-use assets also include any lease payments made to the lessor at or before the commencement date. The Company recognizes operating lease expense on a straight-line basis over the lease period. The total operating lease cost recognized during the three months ended March 31, 2019 was $1.3 million and cash paid for operating leases during the three months ended March 31, 2019 was $1.4 million.
On October 4, 2018, the Company entered into an office lease (“San Francisco Lease”) to rent approximately 117,560 rentable square feet in San Francisco, California, which will become the Company’s new headquarters. The Company’s current headquarters is in the same building as the office space covered by the San Francisco Lease.
The San Francisco lease is expected to commence on or around the second quarter of 2019 and has a twelve-year term, which will expire on August 31, 2031. The Company is entitled to one option to extend the San Francisco Lease for a five-year term, subject to certain requirements. In addition, the landlord will provide a tenant improvement allowance of up to $2.4 million for leasehold improvements in connection with the cost of construction of the initial alterations within the premises. Annual rental payments will be $10.0 million, with a 3% increase each year and will be accounted for in accordance with Topic 842. The Company has obtained a standby letter of credit in the amount of $6.9 million, which may be drawn down by the landlord to be applied for certain purposes upon the Company’s breach of any provisions under the San Francisco Lease.
As of March 31, 2019, maturities of operating lease liabilities were as follows (in thousands):
Minimum future lease payments previously disclosed in the 2018 10-K and under the previous lease accounting standard, which includes annual rental payments for the San Francisco lease which has not commenced as of the reporting date, for the year ended December 31, 2018 are as follows (in thousands):
The weighted average remaining lease term of the Company’s operating leases as of March 31, 2019 was 3.95 years. The weighted average discount rate of the Company’s operating leases is 4.75% as of March 31, 2019. Legal Proceedings From time to time, the Company may become involved in legal proceedings arising from the ordinary course of its business. Management is currently not aware of any matters that could have a material adverse effect on the financial position, results of operations or cash flows of the Company. Indemnifications In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by California corporate law. The Company currently has directors’ and officers’ insurance. The Company has never incurred material costs to defend lawsuits or settle claims related to these indemnification provisions, and believes that the estimated fair value of these indemnification obligations is not material and it has not accrued any amounts for these obligations. |

Debt Disclosure [Abstract] | |
Debt |
7. Debt Pharmakon Loan Agreement In December 2015, the Company entered into a Loan Agreement with Biopharma Secured Investments III Holdings Cayman LP (the “Pharmakon Loan Agreement”). The Pharmakon Loan Agreement provides for up to $55.0 million in term loans split into two tranches as follows: (i) the Tranche A Loans are $30.0 million in term loans, and (ii) the Tranche B Loans are up to $25.0 million in term loans. The Tranche A Loans were drawn on December 4, 2015. The Tranche B Loans were available to be drawn prior to December 4, 2016. No additional draw was taken. The Tranche A Loans bear interest at a fixed rate equal to 9.50% per annum that is due and payable quarterly in arrears. During the first eight calendar quarters, 50% of the interest due and payable was added to the then outstanding principal. In December 2015, the Company used the proceeds from the Pharmakon Loan Agreement to repay $4.9 million of bank debt to Silicon Valley Bank (“SVB”). The issuance costs and debt discount have been netted against the borrowed funds on the balance sheet. On October 23, 2018, the Company repaid the principal amount of the Tranche A Loan of $30.0 million and related accrued interest of $3.3 million. The Company incurred a $3.0 million loss in connection with the early extinguishment of the Pharmakon Loan Agreement which included a prepayment premium fee of $1.0 million and additional consideration related to the prepayment of $1.5 million. Bank Debt In December 2015, the Company entered into a Second Amended and Restated Loan and Security Agreement with SVB, (the “SVB Loan Agreement”). Under the SVB Loan Agreement, the Company may borrow, repay and reborrow under a revolving credit line, but not in excess of the maximum loan amount of $15.0 million, until December 4, 2018, when all outstanding principal and accrued interest becomes due and payable. Any principal amount outstanding under the SVB Loan Agreement shall bear interest at a floating rate per annum equal to the rate published by The Wall Street Journal as the “Prime Rate” plus 0.25%. The Company may borrow up to 80% of its eligible accounts receivable, up to the maximum of $15.0 million. In August 2016, the Company obtained a $3.1 million standby letter of credit pursuant to the SVB Loan Agreement in connection with a lease for its San Francisco office. In October 2018, the Company entered into the Third Amended and Restated Loan and Security Agreement with SVB (“Third Amended and Restated SVB Loan Agreement”). This Agreement amends and restates the Second Amended and Restated Loan and Security Agreement between the Company and SVB dated December 4, 2015, as amended by the First Loan Modification Agreement between the Company and SVB dated August 22, 2016. Pursuant to the Third Amended and Restated SVB Loan Agreement, the Company obtained a term loan (“SVB Term Loan”) for $35.0 million. Total proceeds from the SVB Term Loan were used to pay off the loan agreement with Biopharma Secured Investments III Holdings Cayman LP (“Pharmakon”), totaling $35.8 million. The Company will make interest-only payments through October 31, 2020, followed by 36 monthly payments of principal plus interest on the SVB Term Loan. Interest charged on the SVB Term Loan will be the greater of (a) a floating rate based on the “Prime Rate” published by The Wall Street Journal minus 0.75%, or (b) 4.25%. Under the Third Amended and Restated SVB Loan Agreement, the Company may borrow, repay, and reborrow under a revolving credit line, but not in excess of the maximum loan amount of $25.0 million, which includes an $11.0 million standby letter of credit sublimit availability. In October 2018, a $6.9 million standby letter of credit was obtained in connection with a lease for the Company’s San Francisco headquarters. Any principal amount outstanding under the Third Amended and Restated SVB Loan Agreement revolving credit line shall bear interest at an amount that is the greater of (a) a floating rate per annum equal to the rate published by The Wall Street Journal as the “Prime Rate” or (b) 5.00%. The Company may borrow up to 75% of eligible accounts receivable, up to the maximum of $25.0 million. As of March 31, 2019, no amount was outstanding under the revolving credit line. The Third Amended and Restated Loan Agreement requires the Company to maintain a minimum consolidated liquidity ratio or minimum adjusted Earnings Before Interest, Tax, Depreciation, and Amortization during the term of the loan facility. In addition, the SVB Loan Agreement contains customary affirmative and negative covenants and events of default. The Company was in compliance with loan covenants as of March 31, 2019. The obligations under the Third Amended and Restated Loan Agreement are collateralized by substantially all assets of the Company. California HealthCare Foundation Note In November 2012, the Company entered into a Note Purchase Agreement and Promissory Note with the California HealthCare Foundation (the “CHCF Note”), through which the Company borrowed $1.5 million. The CHCF Note accrued simple interest of 2.0%. The accrued interest and the principal was to mature in November 2016. In partial consideration for the issuance of the CHCF Note, the Company issued warrants to purchase 22,807 shares of the Company’s Series D convertible preferred stock. In June 2015, the Company amended the CHCF Note to extend the maturity date to May 2018. The CHCF Note was subordinate to other debt. In May 2018, the Company repaid the principal amount of $1.5 million and related $0.2 million in accrued interest on the CHCF Note. |

Income Taxes |
8. Income Taxes The Company recorded an immaterial tax provision related to its U.K. entity during the three months ended March 31, 2019. The Company did not record a provision or benefit for income taxes during the three months ended March 31, 2018, as it reported losses in each period which are not more likely than not to be realized. Due to the uncertainties surrounding the realization of deferred tax assets through future taxable income, the Company has provided a full valuation allowance and, therefore, no benefit has been recognized for the net operating loss carryforwards and other deferred tax assets. |

Stock-Based Compensation |
11. Stock-Based Compensation Employee Stock Options Valuation The fair value of employee and director stock options was estimated at the date of grant using a Black-Scholes option valuation model with the weighted average assumptions below.
Stock-Based Compensation The following table summarizes the total stock-based compensation expense included in the statements of operations and comprehensive loss for all periods presented (in thousands):
As of March 31, 2019, there was total unamortized compensation costs of $13.2 million, net of estimated forfeitures, related to unvested stock options which the Company expects to recognize over a period of approximately 2.2 years, $39.5 million, net of estimated forfeitures, related to unrecognized restricted stock unit (“RSU”) expense, which the Company expects to recognize over a period of 2.6 years, and $0.9 million unrecognized ESPP expense, which the Company will recognize over 0.7 years.
Performance based RSUs (“PRSU”)
During the three months ended March 31, 2019, the Company granted PRSUs to key executives of the Company. The performance equity program has a 2-year performance period measuring target revenue Compound Annual Growth Rate (“CAGR”) achievement for fiscal year 2020 compared to fiscal year 2018. There is a minimum performance threshold of 75% to earn 50% of target, and a maximum threshold of 125% achieved to earn 200% of target. The exact number of earned shares will be determined based on linear interpolation using the revenue CAGR as it falls between the minimum and maximum thresholds outlined above. The fair value of the PRSUs granted during the three months ended March 31, 2019 will range from $0 to $19.5 million, depending on the achievement of the performance target. A total of 202,738 PRSUs were granted and the Company did not record any expense for these grants for the three months ended March 31, 2019. In the event that achievement of the performance targets becomes probable, the Company will recognize a cumulative expense amount for prior periods. |

Basis of Presentation |
Basis of Presentation The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, or U.S. GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted, and accordingly the balance sheet as of December 31, 2018, and related disclosures, have been derived from the audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for the fair statement of the Company’s condensed consolidated financial information. Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to current period presentation. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019 or for any other interim period or for any other future year. The accompanying interim unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited financial statements and the related notes thereto for the year ended December 31, 2018 included in the Company’s annual report on Form 10-K, filed with the SEC on March 4, 2019. Revision of Previously Reported Financial Information During the preparation of the Company’s quarterly report on Form 10-Q for the quarter ended March 31, 2019, the Company identified an error in the presentation of the changes in the allowance for doubtful accounts and contractual allowance disclosures in its Quarterly reports for the periods ended March 31, June 30 and September 30, 2018. During these quarters, a portion of the allowance for contractual adjustments was incorrectly presented as a provision for doubtful accounts. The Company concluded that the amounts were not material to any of its previously issued condensed consolidated financial statements. The error impacted the disclosures but did not impact the Company’s condensed consolidated balance sheets, statements of operations or statements of cash flows. The error did not impact the disclosures in the previously issued consolidated financial statements in the Form 10-K for the year ended December 31, 2018. The following tables presents the impact of the revision on the changes in the contractual allowance and allowance for doubtful accounts balances for the interim periods in the year ended December 31, 2018 (in thousands):
Note that the above adjustments did not result in any changes to the Company’s total receivables-related reserves for the periods in the table above.
(1) For the three months ended March 31, 2018, the allowance for contractual adjustments was increased by $1.4 million and the provision for doubtful accounts was reduced by the same amount. (2) For the six months ended June 30, 2018, the allowance for contractual adjustments was increased by $2.0 million and the provision for doubtful accounts was reduced by the same amount. (3) For the nine months ended September 31, 2018, the allowance for contractual adjustments was increased by $2.7 million and the provision for doubtful accounts was reduced by the same amount. In addition, in the contractual allowances table, contractual adjustments were increased by $0.6 million and the allowance for contractual adjustments was reduced by the same amount. |

Accounts Receivable, Allowance for Doubtful Accounts and Contractual Allowance |
Accounts Receivable, Allowance for Doubtful Accounts and Contractual Allowance Accounts receivable consists of amounts due to the Company from institutions, third-party payors, government and commercial payors and their related patients, as a result of the Company's normal business activities. Accounts receivable is reported on the condensed consolidated balance sheets net of an estimated allowance for doubtful accounts and a contractual allowance. The Company establishes an allowance for doubtful accounts for estimated uncollectible receivables based on its historical experience and recognizes the provision as a component of selling, general and administrative expenses. The Company establishes a contractual allowance when it estimates that consideration to be received will be lower than the contracted rate based on its historical experience and recognizes the provision as a reduction to revenue. The following table presents the changes in the allowance for doubtful accounts (in thousands):
The following table presents the changes in the contractual allowance (in thousands):
The following table presents the impact of allowance for doubtful accounts and contractual allowance on accounts receivable (in thousands):
The Company reviews and updates its estimates for the allowances for doubtful accounts and contractual allowance periodically to reflect its experience regarding historical collections. If management were to make different judgments or utilize different estimates in the allowances for doubtful accounts and contractual allowance, differences in the amount of reported selling, general and administrative expenses and revenue could result, respectively. |

Concentration of Credit Risk |
Concentrations of Risk Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, investments and accounts receivable. Cash, cash equivalents, and investments are deposited in financial institutions which, at times may be in excess of federally insured limits. Cash equivalents are invested in highly rated money market funds. The Company invests in a variety of financial instruments, such as, but not limited to, United States Government securities, corporate notes, commercial paper and, by policy, limits the amount of credit exposure with any one financial institution or commercial issuer. The Company has not experienced any material losses on its deposits of cash and cash equivalents or investments. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of customers comprising the Company’s customer base and their dispersion across many geographies. The Company does not require collateral. The Company records an allowance for doubtful accounts when it becomes probable that a receivable will not be collected. Federal government agencies, including Centers for Medicare and Medicaid Services (“CMS”) and the military, accounted for approximately 35% and 37% of the Company’s revenue for the three months ended March 31, 2019 and 2018, respectively. Accounts receivable related to federal government agencies accounted for 19% and 18% at March 31, 2019 and December 31, 2018, respectively. |

Revenue Recognition |
Revenue Recognition The Company’s revenue is generated primarily from the provision of its cardiac rhythm monitoring service, the Zio XT service. The Zio XT is a cardiac rhythm monitoring service that has a patient wear period of up to 14 days and is billable when the monitoring reports are delivered to the healthcare provider, which is also when the service is complete and the Company recognizes revenue. The time from when the patient has the Zio XT device applied to the time the report is posted is generally around 20 days. The Company accounts for contract revenue with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company's revenue is measured based on consideration specified in the contract with each customer. A unique aspect of healthcare is the involvement of multiple parties to the service transaction. In addition to the patient, often a third-party, for example a commercial or governmental payor or healthcare institution, like a hospital or clinic, will pay the Company for some or all of the service on the patient’s behalf. Separate contractual arrangements exist between the Company and third-party payors that establish amounts the third-party payor will pay on behalf of a patient for covered services rendered and should be considered in determining collectability and the transaction price for services provided to a patient covered by that third-party payor.
The Company recognizes revenue on an accrual basis based on estimates of the amount that will ultimately be realized. These estimates require significant judgment by management. In determining the amount to recognize for a delivered report, the Company considers factors such as claim payment history from both payors and patient out-of-pocket costs, payor coverage, whether there is a contract between the payor or healthcare institution and the Company, historical amount received for the service, and any current developments or changes that could impact reimbursement and healthcare institution payments.
A summary of the payment arrangements with third-party payors and healthcare institutions is as follows:
The Company is utilizing the portfolio approach practical expedient under ASC 606 for revenue recognition. The Company accounts for the contracts within each portfolio as a collective group, rather than individual contracts. Based on history with these portfolios and the similar nature and characteristics of the patients within each portfolio, the Company has concluded that the financial statement effects are not materially different than if accounting for revenue on a contract-by-contract basis.
For the healthcare institution, the Company has historical experience of collecting substantially all of the negotiated contractual rates and determined at contract inception that these customers, and or their related third-party payor that pays the Company on their behalf, have the intention and ability to pay the promised consideration. As such, the Company is not providing an implicit price concession but, rather, has chosen to accept the risk of default, and any subsequent impairment of the related receivable are recorded as bad debt expense.
For contracted and CMS portfolios, the Company is providing an implicit price concession because, while the Company has a contract with the underlying payor, the Company expects to accept a lower amount of consideration when claims are adjudicated and allowable claims are determined by the commercial payor. The implicit price concession is recorded as variable consideration to the transaction price and recorded as an adjustment to revenue as a contractual allowance. Historical cash collection indicates that it is probable that substantially all of the allowable claim amount will be received, and hence this amount is recorded as revenue. Any subsequent impairment of the related receivable is recorded as bad debt expense.
For non-contracted portfolios, the Company is providing an implicit price concession because the Company does not have a contract with the underlying payor, the result of which requires the Company to estimate transaction price based on historical cash collections utilizing the expected value method. Subsequent adjustments to the transaction price are recorded as an adjustment to revenue and not as bad debt expense. Disaggregation of Revenue The Company disaggregates revenue from contracts with customers by payor type. The Company believes these categories aggregate the payor types by nature, amount, timing and uncertainty of its revenue streams. Disaggregated revenue by payor type and major service line for the three months ended March 31, 2019 was as follows (in thousands):

Contract Liabilities |
Contract Liabilities ASC 606 requires an entity to present a revenue contract as a contract liability when the Company has an obligation to transfer goods or services to a customer for which the Company has received consideration from the customer, or an amount of consideration from the customer is due and unconditional (whichever is earlier). Certain of the Company’s customers pay the Company directly for the Zio XT service upon shipment of devices. Such advance payments, or contract liabilities are recorded as deferred revenue on the Condensed Consolidated Balance Sheets and revenue is recognized when reports are delivered to physicians. Total revenue recognized during each of the three months ended March 31, 2019 and March 31, 2018 that was included in the contract liability balance at the beginning of each respective period was $1.2 million. |

Contract Costs |
Contract Costs Under ASC 340, the incremental costs of obtaining a contract with a customer are recognized as an asset. Incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained.
The Company’s current commission programs are considered incremental. However, as a practical expedient, ASC 340 permits the Company to immediately expense contract acquisition costs, as the asset that would have resulted from capitalizing these costs will be amortized in one year or less. |

Leases |
Leases
Identifying a lease
The Company determines whether a contract contains a lease at the inception of a contract. If the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration, the Company considers the contract to contain a lease. The Company determines whether a contract conveys the right to control the use of an identified asset for a period of time if the contract contains both of the following terms:
Discount Rate for leases On January 1, 2019, the rate implicit in the Company’s leases was not readily determinable. As such, the Company used its incremental borrowing rate to calculate its right-of-use assets and lease liabilities. The Company determined the appropriate incremental borrowing rate by utilizing the interest rate obtained in connection with the Third Amended and Restated Loan and Security Agreement with Silicon Valley Bank which was finalized on October 23, 2018. Lease term The lease term is generally the minimum noncancelable period of each lease. The Company does not include option periods in determining the right-of-use asset and right-of-use liability unless it is reasonably certain that the Company will exercise the option at inception or when a triggering event occurs. As of March 31, 2019, the Company did not include any options to renew in the lease terms of its current lease portfolio. |

Recently Adopted Accounting Guidance |
Recently Adopted Accounting Guidance In February 2016, the Financing Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (“Topic 842”), which requires lessees to recognize lease liabilities and corresponding right-of-use assets on the consolidated balance sheet for all leases. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset and, for operating leases, the lessee would recognize a straight-line lease expense. Topic 842 also changes the definition of a lease and expands the disclosure requirements of lease arrangements. The Company has no embedded leases with suppliers. Upon adoption of Topic 842 on January 1, 2019 using the modified retrospective method, the Company recognized right-of-use assets of $10.4 million and lease liabilities of $10.2 million. There was no cumulative-effect adjustment recorded on January 1, 2019. The Company adopted the following practical expedients allowed under Topic 842:

- Definition Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.
