Description
Hanke Zheng, Jonathan D. Campbell, and Julie A. Patterson track Medicare Part D coverage shifts after a major law change in a 2026 study. The Inflation Reduction Act capped patient out-of-pocket costs and raised plan liability from January 2025. That shift may push plans to exclude more brand drugs in crowded classes, the authors reason.
Using a commercial formulary database, they compared Medicare plans with commercial plans from 2024 through 2026. Classes counted as competitive when at least three eligible brand-only drugs were on the market. Beneficiary impact was projected from 2024 enrollment, framing a watch on access in contested drug classes.
