PEAKS Act

Treats certain hospitals that previously met the 15‑mile mountainous/secondary‑road distance test as satisfying that distance requirement for Critical Access Hospital (CAH) designation beginning January 1, 2026, provided the hospital can show it met the distance test at its last certification. Requires the Secretary (CMS) to issue implementing regulations within one year. The bill also amends the Medicare distance rules that apply to ambulance services provided by CAHs, but the specific text of that amendment was not included in the provided document.
