Medicare and Medicaid — the two largest government healthcare programs — collectively cover approximately 150 million Americans and determine the financial performance of every major payer, distributor, and pharmacy chain covered in this report. CMS reimbursement rules for Medicare Advantage, drug pricing under the Inflation Reduction Act, Medicaid managed care rate adequacy, and prior authorization reform are the four most consequential policy dynamics for the leading healthcare companies in 2025-2026. The 2025 Medicare Advantage rate notice — which reduced funding relative to industry expectations — was the primary driver of elevated medical cost ratios and margin pressure across the industry.
