MedPAC’s March 2026 report to Congress reviews Medicare payment adequacy, beneficiary cost burdens, spending trends, and reform options across major payment systems. It provides a cross-cutting baseline for understanding where Medicare costs are rising, how payment rates compare with provider costs, and what policy changes lawmakers could consider. The report is especially useful for comparing cost pressures across hospital, physician, post-acute, and other sectors rather than focusing on a single CMS rule.
