CY2020	us-gaap	Prior Period Reclassification Adjustment Description PriorPeriodReclassificationAdjustmentDescription	Certain prior-year amounts have been reclassified to conform to the current year presentation. In our consolidated balance sheets, contract liabilities and contract liabilities – long-term, primarily related to Medicare advance payments we received, are now presented separately due to the fact that the balances increased substantially in 2020. Additionally, our financial statements and corresponding disclosures for prior periods have been recast to reflect retrospective application of the change in accounting principle discussed in the Professional and General Liability Reserves section of this note.
CY2020	us-gaap	Use Of Estimates UseOfEstimates	The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and these accompanying notes. We regularly evaluate the accounting policies and estimates we use. In general, we base the estimates on historical experience and on assumptions that we believe to be reasonable given the particular circumstances in which we operate. Although we believe all adjustments considered necessary for a fair presentation have been included, actual results may vary from those estimates. Financial and statistical information we report to other regulatory agencies may be prepared on a basis other than GAAP or using different assumptions or reporting periods and, therefore, may vary from amounts presented herein. Although we make every effort to ensure that the information we report to those agencies is accurate, complete and consistent with applicable reporting guidelines, we cannot be responsible for the accuracy of the information they make available to the public.
