Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2021
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. The quarterly tax provision and the estimate of our annual effective tax rate are subject to variation due to several factors, including variability in our loss before income taxes, the mix of jurisdictions to which such income or loss relates, changes in how we conduct business, and tax law developments. For the three months ended March 31, 2021 and 2020, our estimated effective tax rate was (0.4)% and 6.6%, respectively. The variations between our estimated effective tax rate and the U.S. statutory rate are primarily due to our full valuation allowance. We consider all available evidence to evaluate the recovery of deferred tax assets, including historical levels of income, legislative developments, and risks associated with estimates of future taxable income. We have provided a full valuation allowance for our net deferred tax assets as of March 31, 2021 and December 31, 2020, due to the uncertainty surrounding the future realization of such assets and the cumulative losses we have generated. As we have a full valuation allowance on net deferred tax assets, our income tax provision for the three months ended March 31, 2021 consists primarily of minimal state and foreign income taxes. The income tax benefit of $1.2 million recorded for the three months ended March 31, 2020, is primarily related to the discrete deferred tax benefit attributable to the release of a portion of the valuation allowance during the quarter. The release of valuation allowance is attributable to the acquisition of Able Health, which resulted in deferred tax liabilities that, upon acquisition, allowed us to recognize certain deferred tax assets of $1.3 million that had previously been offset by a valuation allowance. We recognize tax benefits from uncertain tax positions when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. We believe that we have provided adequate reserves for income tax uncertainties in all open tax years. We do not anticipate material changes in the total amount of our unrecognized tax benefits within 12 months of the reporting date. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was enacted and signed into U.S. law to provide economic relief to individuals and businesses facing economic hardship as a result of the COVID-19 pandemic. On March 11, 2021, the American Rescue Plan Act of 2021 (ARPA) was enacted and signed into U.S. law to provide additional economic stimulus and tax credits. Changes in tax laws or rates are accounted for in the period of enactment. We are continuing to analyze these legislative developments and believe that the income tax provisions of the CARES Act and ARPA do not have a significant impact on our current taxes, deferred taxes, or uncertain tax positions.
