Coverage and Medical Necessity

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.

Medical necessity for ambulance transport

Covered when ALL of the following are met

Primary rule

Accompaniment or conditions
- Emergency occurrence: A medical emergency occurred in which the recipient needed emergency medical care
  Emergency medical care means services to prevent loss of life or aggravation of illness or injury
- Bed-confined: Recipient was bed-confined before and after transport (unable to get up from bed without assistance, unable to ambulate, and unable to sit in a chair or wheelchair)
- Endangerment: Use of any other mode of transportation would have endangered the health of the recipient
  Examples: restraints needed; unconscious or in shock; requires oxygen or other emergency treatment during transport; signs of acute respiratory or cardiac distress (eg, shortness of breath, chest pain); signs suggesting acute stroke; fracture not set or possible fracture requiring immobility; recipient movable only by stretcher

Operational note: Documentation must support that other modes were contraindicated (e.g., bed‑confined status, need for stretcher, need for oxygen or emergency treatment, restraints, unconscious/shock, acute respiratory/cardiac/stroke signs) or that transport met emergency criteria

See provider documentation requirements

BLS and ALS reimbursement criteria

Service-level reimbursement criteria

BLS: Basic Life Support (BLS): Emergency care skills per NHTSA/EMS education standards; includes administration of oxygen, the patient's prescribed nitroglycerin, bronchodilator inhaler, or epinephrine autoinjector, and selected over‑the‑counter medicines (e.g., activated charcoal); does not include manual defibrillation.

BLS may be billed as emergency or non‑emergency per level definitions

ALS: Advanced Life Support (ALS): Patient's medical condition necessitates one of the ALS emergency care techniques: manual electric cardiac defibrillation, administration of antiarrhythmic agents, intramuscular therapy, endotracheal intubation devices, or intravenous therapy.

ALS subdivided into ALS1 and ALS2

ALS2 specific: ALS2 (always an emergency) requires EITHER at least three separate administrations of one or more medications by IV push/bolus or continuous infusion (excluding crystalloid fluids) OR at least one specified ALS2 procedure (manual defibrillation/cardioversion; endotracheal intubation; central venous line; cardiac pacing; chest decompression; surgical airway; or intraosseous line).

Ambulance services provided when a recipient is treated and stabilized at the scene are generally payable; however, if the recipient refuses transport after being treated and stabilized at the scene, ambulance services will not be covered.

Non-emergency ambulance transports are reimbursable only if the transport is to an enrolled Medicaid provider for a covered Medicaid service. Non-emergency transports to non-enrolled providers or transports that do not meet the policy’s contraindication criteria are not reimbursable.

Provider Requirements, Documentation, and Reimbursement Prerequisites

Note

Reimbursement prerequisites — Non-emergency vs. Emergency

Non-emergency ambulance transports are reimbursable only if the transport is to an enrolled Medicaid provider for a covered Medicaid service. Emergency ambulance services are reimbursable only when a sudden, unexpected occurrence necessitates immediate and rapid ambulance transport to receive emergency medical care. Ambulance services may be reimbursed when a recipient is treated and stabilized at the scene without being transported to a hospital; however, if a recipient refuses transport, ambulance services will not be covered.

Note

Documentation Required

Required clinical justification

Documentation must support that other modes of transportation were contraindicated. Acceptable clinical justification includes evidence the recipient required accompaniment by credentialed medical personnel and one or more of the following: bed-confined status (unable to get up from bed without assistance, unable to ambulate, unable to sit in a chair or wheelchair), need for stretcher, need for oxygen or other emergency treatment during transport, need for restraints to prevent injury, unconsciousness or shock, signs of acute respiratory or cardiac distress (e.g., shortness of breath, chest pain), signs suggestive of acute stroke, or an untreated fracture requiring immobility. Records should show why alternative transport (private vehicle, taxi, wheelchair van) would have endangered the recipient's health.

Denial Risk

Conditions triggering denial

Transport is reimbursable only if all other modes of transportation are contraindicated. Deny reimbursement when documentation does not support medical necessity or contraindication of other transport modes. Specific conditions triggering denial include: absence of bed-confined status or equivalent clinical need; ability to ambulate or sit in a chair or wheelchair without assistance; transport not to an enrolled Medicaid provider for non-emergency services; recipient refusal of transport; lack of documentation that oxygen, stretcher, or credentialed medical accompaniment was required; and transports for which the medical record shows no acute respiratory, cardiac, stroke signs, shock, restraints requirement, or untreated fracture necessitating immobility. Also deny when services billed as emergency are not supported by sudden unexpected need for immediate care.

Non-emergency transport to a non-enrolled provider — not reimbursable
Recipient refused transport — not reimbursable
No documentation that other modes were contraindicated — not reimbursable
Claims billed as emergency without documentation of sudden, unexpected need — not reimbursable

Background and Policy Purpose

Ambulance conveyances are intended to transport sick or injured patients when other modes of transportation are contraindicated. The policy differentiates transport types: emergency ambulance services are reimbursable when a sudden unexpected occurrence necessitates immediate, rapid transport for emergency medical care, while non-emergency ambulance services are reimbursable only when the destination is an enrolled Medicaid provider for a covered service. Additionally, the policy notes that services rendered when a recipient is treated and stabilized on scene may be reimbursed, but refusal of subsequent transport by the recipient voids coverage for those ambulance services.

Key Definitions

inv-11: Ambulance

DefinitionAn ambulance is a publicly or privately owned means of conveyance for the transportation of sick, injured, or wounded patients.

Medical necessity conditionTransportation by ambulance may be covered when all other modes of transportation are contraindicated and the recipient needs transport to the nearest appropriate facility for treatment.

When other modes contraindicatedOther modes may be contraindicated when recipient requires accompaniment by credentialed medical personnel and either an emergency occurred, the recipient was bed-confined, or other transport would have endangered the recipient's health.

Examples of endangermentRestraints needed, unconscious/shock, need for oxygen or emergency treatment during transport, acute respiratory or cardiac distress, possible acute stroke, unset/possible fracture requiring immobility, or movable only by stretcher.

inv-12: Bed-confined

DefinitionBed-confined means unable to get up from bed without assistance, unable to ambulate, and unable to sit in a chair or wheelchair.

Relevance to coverageRecipient bed-confined before and after transport constitutes a condition where other modes of transportation may be contraindicated, supporting ambulance reimbursement.

Documentation implicationClinical documentation should confirm inability to ambulate or sit and that assistance is required to get out of bed.
