Insurance [Abstract] |
MEDICARE PART D | MEDICARE PART D We cover prescription drug benefits in accordance with Medicare Part D under multiple contracts with the Centers for Medicare and Medicaid Services, or CMS. The accompanying condensed consolidated balance sheets include the following amounts associated with Medicare Part D at March 31, 2025 and December 31, 2024. CMS subsidies/discounts include the reinsurance and low-income cost subsidies funded by CMS for which we assume no risk as well as brand name prescription drug discounts for Part D plan participants funded by CMS and pharmaceutical manufacturers. Effective January 1, 2025, the Medicare Part D coverage gap was eliminated as mandated by the Inflation Reduction Act of 2022. The standard Part D benefit now comprises three phases: the deductible phase, the initial coverage phase and the catastrophic coverage phase. Beneficiaries' out-of-pocket expenses for covered prescription drugs are capped at $2,000, after which they incur no additional cost sharing for the remainder of the year. In addition, the Coverage Gap Discount Program was replaced by the Manufacturer Discount Program, requiring pharmaceutical manufacturers to provide discounts on brand name drugs during both the initial coverage and catastrophic phases. These changes are anticipated to reduce out-of-pocket costs for beneficiaries and impact plan liabilities accordingly. The accompanying condensed consolidated balance sheets include $455 million of net assets and $530 million of net assets associated with subsidy programs at March 31, 2025 and December 31, 2024, respectively. The accompanying condensed consolidated balance sheets also include $167 million of net liabilities and $126 million of net assets associated with cost sharing programs at March 31, 2025 and December 31, 2024, respectively. For additional information regarding our prescription drug benefits coverage in accordance with Medicare Part D, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" in our 2024 Form 10-K.
