Coverage and Medical Necessity Criteria
Medical Necessity and Destination Criteria
Covered when ALL of the following are met
Overall coverage
Medical necessity
- Bed-confined: (1) Be confined to bed; unable to get up from bed without assistance; (2) Unable to walk; (3) Unable to sit in a chair or a wheelchair.
All three items 1–3 must be present to qualify as bed-confined.
- Alternate necessity: Needs vital medical services during the trip that are only available in an ambulance (example: administration of medications or monitoring of vital functions).
- Origin and destination: Transport must be to a covered destination and meet the origin/destination requirements as listed by the plan (e.g., hospital, critical access hospital, skilled nursing facility, and other covered facility pairs in the destination matrix).
Lack of alternative transportation alone does not create medical necessity; see destination matrix for specific allowed pairs and authorization limits.
Documentation must support bed-confined status or need for ambulance-only services and must indicate origin and destination to confirm coverage.
Transportation by car, taxi, bus, gurney van, wheelchair van, minivan, or any other non-licensed ambulance is not covered for non‑emergency ambulance benefit determinations. The policy explicitly excludes these modes of transport even if they are the only way the member can travel to a facility.
Ambulance services are not covered when the patient's condition does not require services that are only available in a licensed ambulance or when other means of transportation would not endanger the patient’s health. The policy states that lack of alternative transportation alone does not create medical necessity, and ambulance coverage also requires that origin/destination criteria are met.

Authorization, Documentation, and Provider Requirements
Prior Authorization Required
Prior authorization is required and applied per origin/destination pair. Authorizations specify the approved number of transports and an authorization end date (typically date(s) of service or a DOS range). Open authorizations will be reviewed at least every 30 days to confirm continued medical appropriateness and medical necessity; authorizations may be modified or revoked based on review.
- Authorizations are origin/destination specific
- Authorization includes authorized number of transports (single, series, or specified count)
- Authorization end date: DOS or DOS range
- Open authorizations are reviewed every 30 days for continued medical appropriateness
Required Documentation to Support Medical Necessity
Documentation submitted must support that the beneficiary meets medical necessity criteria and origin/destination requirements. Specifically, documentation should show that the patient is bed‑confined (meets all of the first three criteria) or requires vital medical services during transport that are only available in an ambulance. Examples: notes confirming patient is confined to bed and unable to get up without assistance, unable to walk, unable to sit in a chair or wheelchair, or documentation of need for ambulance‑only medication administration or monitoring during transport.
- Medical necessity documentation must demonstrate bed‑confined status OR need for vital medical services only available in an ambulance
- Include clinical notes, mobility assessments, and orders supporting the transport modality and destination
- Documentation must also support the origin and destination pairing covered under the authorization
Denial Triggers and Common Reasons for Non‑Coverage
Ambulance services will be denied when medical necessity criteria are not met or when the condition does not require ambulance‑only services. Denial triggers include: lack of bed‑confined status (unless ambulance‑only vital services are documented), availability of other safe transportation (lack of alternative transportation is not sufficient to establish medical necessity), transportation to non‑covered destinations, or transport by non‑ambulance vehicles. Ensure documentation addresses both clinical need and that the destination is an approved origin/destination pairing.
- No coverage if patient does not require ambulance‑only services and could be safely transported by other means
- Lack of alternative transportation is NOT a basis for coverage
- Transportation by non‑ambulance vehicles (taxi, wheelchair van, etc.) is excluded even if otherwise necessary
- Destination must be one of the covered origin/destination pairs listed in the authorization
Background and Policy Context
The purpose of non‑emergency ambulance coverage is to pay for licensed ambulance transport only when the member’s medical condition necessitates ambulance‑level services and when transport is between covered origin/destination pairs. Coverage requires that the patient either meet the bed‑confined or equivalent medical necessity criteria (i.e., require services available only in an ambulance) and that the trip meets the specified origin/destination requirements; the policy makes clear that simply having no other means of transportation does not establish medical necessity.
Key Definitions
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
