CY2022	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company bases its estimates on the information available at the time, its experiences and various other assumptions believed to be reasonable under the circumstances including estimates of the impact of COVID-19. The areas where significant estimates are used in the accompanying financial statements include revenue recognition, the liability for unpaid claims, valuation and related impairment recognition of long-lived assets, including intangible assets and goodwill and the valuation of stock options. Actual results could differ from those estimates.
CY2022	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of capitated accounts receivable. The Company’s concentration of credit risk is limited by the diversity, geography and number of patients and payers.
