What it does
This bill expands Medicare's definition of 'critical access hospital' to include certain hospitals located on Indian reservations. Starting August 1, 2025, a state may designate a reservation-based facility as a critical access hospital if it is more than 35 miles (or 15 miles in mountainous terrain) from another hospital or Indian Health Service facility. These hospitals may also establish psychiatric and rehabilitation units without the normal bed-count limits.
Why we flagged it
The bill's operative mechanism is a straightforward expansion of Medicare eligibility criteria to include reservation-based hospitals, removing geographic and operational barriers that previously excluded tribal healthcare facilities from critical access hospital status.
What the text implies
- Critical access hospital designation triggers higher Medicare reimbursement rates (typically 101% of reasonable costs), which may increase federal healthcare spending for reservation-based facilities but improves financial viability of tribal healthcare systems.
- The 35-mile (or 15-mile mountainous) distance threshold is measured from other reservation or IHS facilities, not from all hospitals, which may permit designation of facilities closer to non-tribal hospitals—a narrower geographic exclusion than standard critical access rules.
