Coverage Criteria for Non-Emergency Ground Ambulance

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Covered when medical necessity AND origin/destination criteria are met

Covered when ALL of the following requirements are met:

Overall: Ambulance transport is covered when the transport is non-emergency and the patient meets medical necessity criteria AND the transport meets the approved origin and destination requirements.

Based on CMS ambulance coverage guidance; reviewers will verify both medical condition and destination pairing.

Medical necessity

A. Bed-confined (all of the following)
- 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.
B. Needs ambulance-only services: Need vital medical services during the trip that are only available in an ambulance (e.g., administration of medications or monitoring of vital functions).

Origin and destination

Examples of origin→destination pairings and auth rules: Refer to policy destination table for complete pairings; samples include: ACC/CDU→SNF/Rehab/LTAC (Auth # = 1; End Date = DOS), ACC/CDU→Dialysis (Auth # = 2; End Date = DOSs), SNF/Rehab→Hospital (Auth # = Series; End Date = DOS Range), SNF/Rehab→MD Office—Wound care (Auth # = Series; End Date = DOS Range), MOB→Hospital (Auth # = 1; End Date = DOS), Home↔Hospital (various rules: Home→Hospital may be Series with DOS Range depending on pairing), and Hospital→Dialysis (Auth # = Series; End Date = DOS Range).
See source destination sections for full pairing and authorization detail.

Transportation by car, taxi, bus, gurney van, wheelchair van, minivan, and any other type of transportation other than a licensed ambulance are expressly excluded from coverage under the ambulance benefit. These non-ambulance modes are not covered even when they may be the only available means to travel to a facility; coverage is limited to licensed ambulance services when the policy's medical necessity and origin/destination requirements are met.

The absence of alternative transportation options alone does not establish medical necessity for ambulance services. Lack of alternative transportation services by itself will not justify coverage; medical necessity must be demonstrated per the policy criteria (e.g., bed-confined status or need for ambulance-only medical services).

Provider Requirements and Authorization

Prior Authorization

Prior Authorization Required

Prior authorization required for non-emergency ambulance transports. Authorizations specify an allowed number of transports (single, series, or 2) and an authorization end date tied to the date(s) of service. Open authorizations may be reviewed every 30 days for continued medical appropriateness and medical necessity.

Auth types seen in destination matrix: single (1), series, or 2
Auth end date examples: DOS, DOS Range, DOSs
Authorization reviews: every 30 days

Denial Risk

Alternative Transport Requirement

Ambulance transport is covered only when other means of transportation would endanger the member's health or the member requires services that can only be provided in an ambulance. Lack of alternative transportation alone does NOT establish medical necessity.

Covered only if non-ambulance transport would endanger health
Covered if services required during transport are only available in an ambulance
Lack of alternative transportation is not sufficient to authorize ambulance services

Documentation Required

Required Documentation

Document medical necessity thoroughly to support ambulance requests. Include evidence of bed‑confined status (items 1–3) or documentation that ambulance‑level services are required during the trip, plus origin and destination details and the requested authorization parameters.

Bed‑confined documentation: statements addressing all three required elements (confined to bed/unable to get up without assistance; unable to walk; unable to sit in a chair or wheelchair) OR documentation of need for ambulance‑only medical services (e.g., meds administration, vital monitoring)
Origin and destination: specify facility types (e.g., SNF/Rehab, Hospital, Dialysis, Home, ACC/CDU, MOB, LTAC) and that destination is a covered type per the matrix
Authorization details: requested number of transports (single, series, or 2) and corresponding auth end date (DOS, DOS Range, DOSs)

Denial Risk

Denial Triggers

Ambulance transport will be denied if medical necessity criteria are not met, the destination is not a covered destination, or if documentation shows that non-ambulance transport would not endanger health. Bed‑confinement alone, without meeting the full criteria, is insufficient.

Denial triggers: failure to meet bed‑confined criteria or need for ambulance‑only services
Denial triggers: destination not listed as covered in the destination matrix
Denial triggers: documentation indicates other transport would not endanger the member

Background and Policy Basis

This guidance is aligned with CMS Medicare ambulance coverage rules for non-emergency ground ambulance. Ambulance transport is covered only when the beneficiary's medical condition requires services that only a licensed ambulance can provide, the use of other transportation would endanger the patient’s health, and the origin-to-destination pairing meets the approved list and authorization rules. The policy emphasizes that meeting origin/destination requirements and demonstrating medical necessity are both required for coverage.
