Retirement Benefits [Abstract]
Employee Benefit Plans	NOTE 13 — EMPLOYEE BENEFIT PLANS We maintain defined contribution benefit plans that are available to employees who meet certain minimum requirements. Certain of the plans require that we match specified percentages of participant contributions up to certain maximum levels (generally, 100% of the first 3% to 9%, depending upon years of vesting service, of compensation deferred by participants). The cost of these plans totaled $532 million for 2019, $499 million for 2018 and $471 million for 2017. Our contributions are funded during the applicable or following year. We maintain the noncontributory, nonqualified Restoration Plan to provide certain retirement benefits for eligible employees. Eligibility for the Restoration Plan is based upon earning eligible compensation in excess of the Social Security Wage Base and attaining 1,000 or more hours of service during the plan year. Company credits to participants’ account balances (the Restoration Plan is not funded) depend upon participants’ compensation, years of vesting service and certain IRS limitations. Benefits expense under this plan was $44 million for 2019, $22 million for 2018 and $40 million for 2017. Accrued benefits liabilities under this plan totaled $227 million at December 31, 2019 and $205 million at December 31, 2018. We maintain a Supplemental Executive Retirement Plan (“SERP”) for certain executives (the SERP is not funded). The plan is designed to ensure that upon retirement the participant receives the value of a prescribed life annuity from the combination of the SERP and our other benefit plans. Benefits expense under the plan was $19 million for 2019, $26 million for 2018 and $28 million for 2017. Accrued benefits liabilities under this plan totaled $192 million at December 31, 2019 and $195 million at December 31, 2018. We maintain defined benefit pension plans which resulted from certain hospital acquisitions in prior years. Benefits expense under these plans was $11 million for 2019, $9 million for 2018, and $14 million for 2017. Accrued benefits liabilities under these plans totaled $63 million at December 31, 2019 and $68 million at December 31, 2018.
