The Ground Emergency Medical Transportation (GEMT) program is a cornerstone federal Medicaid supplemental reimbursement mechanism operating under Title XIX of the Social Security Act. Its purpose is straightforward: to bridge the documented gap between what Medicaid pays for emergency ambulance transport and what it actually costs public agencies to provide that service. Without GEMT, those unreimbursed costs fall on local taxpayers through cost-shifting, an outcome that contradicts the shared federal-state Medicaid compact.
On May 20, 2026, the Centers for Medicare & Medicaid Services published a Notice of Proposed Rulemaking (NPRM), docket CMS-2449-P, that would cap targeted Medicaid supplemental payments, including GEMT, at the equivalent Medicare Ambulance Fee Schedule (AFS) rates. If finalized, this rule would systematically dismantle the financial foundation of emergency medical services for public agencies nationwide, with no demonstrated basis in fraud, waste, or program abuse by GEMT participants.
The report linked here presents a comprehensive history of the GEMT program. It includes a detailed analysis of CMS-2449-P and a structured opposition argument grounded in law, program design, financial equity, and public safety outcomes.
Key Facts at a Glance
- GEMT is authorized under Title XIX of the Social Security Act; the same authority as CPE and IGTprograms.
- All GEMT participants are governmental entities, tribal governments, or entities with taxing authority, but excludes private companies.
- Reimbursement is based entirely on audited, CMS-approved cost reports, not estimates or projections.
- No fraud, waste, or abuse has been documented against GEMT public providers.
- The proposed rule would cap supplemental payments at Medicare AFS rates, effective January 1, 2029.
- Volunteer, rural, and small agencies face disproportionate harm as they have higher costs and lower commercial offset ability.
- Comment deadline: July 21, 2026.
