INSURANCE/HEALTH: Provides relative to Medicare as the secondary payer for retirees with employer-sponsored health insurance (OR NO IMPACT See Note)

HB 771 requires health insurers to treat Medicare as the primary payer for retirees who return to work and receive employer-sponsored health coverage, meaning Medicare covers costs first rather than secondary. It applies specifically to Medicare-eligible retirees who previously retired but are now reemployed under an employer health plan regulated under state law. The bill mandates insurers coordinate payments this way unless federal law (like 42 CFR §411.32) requires otherwise, without changing existing coverage benefits. This clarifies payment order between Medicare and employer plans for affected retirees.
