Ground ambulance — NSA does NOT cover it

The federal No Surprises Act covers air ambulance but explicitly excludes ground ambulance. Approximately 10-15 states have their own ground-ambulance balance-billing protections in force. The rest leave consumers without state-level balance-billing protection for ground ambulance.

Why ground ambulance was excluded

When Congress enacted the No Surprises Act, ground-ambulance services were left out due to lobbying concerns about reimbursement complexity for ground-ambulance operators (many of which are municipal or volunteer-staffed). NSA established an Advisory Committee on Ground Ambulance and Patient Billing to study the issue, but as of writing, no federal balance-billing protection exists for ground ambulance.

What it means for ERISA self-funded plans

Even where state law exists, ERISA self-funded plans escape state regulation under federal preemption (29 U.S.C. §1144). If you're on a self-funded employer plan, the state ground- ambulance protection may not reach your bill. Negotiation with the ambulance provider is often the only option for ERISA self-funded plan members.

What patients can do

  • Look up your state. Click your state above. If state law applies, the state DOI consumer-protection page is the starting point.
  • Request an itemized bill from the ambulance provider in writing. Many ambulance bills include line items that can be negotiated down.
  • Ask about hardship discounts. Municipal and non-profit ambulance providers often have hardship discount policies.
  • If your plan paid an OON rate, request a re-review citing medical necessity. The plan may agree to recompute.
