Policy

EMERGENCY TRANSPORT

In unique circumstances, air ambulance services may be considered medically necessary. In these situations, the service must be medically appropriate and meet all of the following criteria:
  • The individual's medical condition requires immediate and rapid transport that cannot be provided by land ambulance.
  • The individual's medical condition is one for which the time needed to transport by land may pose a threat to the individual's health.
  • Great distances, limited time-frames, or other obstacles are involved in transporting the individual from his or her home, scene of an accident, or medical emergency to the nearest hospital or other emergency care facility that can appropriately manage the individual's emergency.
OR
  • The point of pick-up is inaccessible by land vehicle and the individual's medical condition requires immediate and rapid transport.
In products with worldwide coverage for emergency care, emergency transport for individuals in a foreign country or in non-US territory waters may be covered to the nearest appropriate facility with the capability of treating the member’s medical condition. Once the individual is admitted to the hospital and stabilized, transport back to the US is not covered.

DECEASED INDIVIDUALS​
Air ambulance services for deceased individuals is covered in either of the following scenarios when the above criteria for Emergency Transport is met:
  • ​the individual was pronounced dead while en route or upon arrival at the hospital or final destination, or
  • the air ambulance takes off to pick up the individual, but the individual is pronounced dead before being loaded onto the ambulance for transport (either before or after the ambulance arrives on the scene). In this circumstance, the appropriate air base rate (e.g., fixed wing or rotary wing) without mileage will be eligible for reimbursement consideration. ​
NON-EMERGENCY TRANSPORT

Individuals enrolled in Medicare Advantage plans are specifically limited to emergency air ambulance transport. Non-emergency air transport is considered a non-covered service by Medicare.

HOSPITAL TO HOSPITAL

Air ambulance transport may be considered medically necessary to transfer an individual from one acute care hospital to the nearest Participating Facility Provider within the member’s service area (HMO) or to a Preferred Facility Provider (PPO) within a reasonable distance, as determined by the Carrier, with the capability of treating the condition for which transfer is necessary, if transportation by land ambulance would endanger the member's health and the transferring hospital does not have adequate facilities to provide the medical services needed by the member.

MISCELLANEOUS ITEMS AND SERVICES

When the air ambulance transport is covered, miscellaneous items and services associated with the transport are also covered. However, reimbursement eligibility varies as follows:
  • Services including oxygen, drugs, disposable supplies (e.g., gauze, dressings, cervical collars), the use of extra attendants, and EKG testing are not eligible for separate reimbursement, regardless of the provider's participation status with the Company, because they are always integral to the primary ambulance service.
  • Reusable devices and equipment (e.g., backboards, inflatable splints) are not eligible for separate reimbursement, regardless of the provider's participation status with the Company, because they are always integral to the primary ambulance service.
  • Waiting time is not eligible for separate reimbursement because it is always integral to the primary ambulance service.
REQUIRED DOCUMENTATION

The individual's medical record must reflect the medical necessity for the care provided. These medical records may include, but are not limited to: records from the professional provider's office, hospital, nursing home, home health agencies, therapies, and test reports.

The Company may conduct reviews and audits of services to our members, regardless of the participation status of the provider. All documentation is to be available to the Company upon request. Failure to produce the requested information may result in a denial for the service.

Guidelines

The vehicle and crew utilized for air ambulance transport should meet all applicable local, state, and federal regulatory certification and licensing requirements.

Description

AIR AMBULANCE

There are two categories of air ambulance services: fixed wing (airplane) and rotary wing (helicopter). An air ambulance is an aircraft used for emergency medical assistance in situations where either a traditional ambulance cannot reach the scene easily or quickly enough, or the individual needs to be transported over a distance or terrain that makes air transportation the most practical transport mode. Air ambulance crews are supplied with equipment that enables them to provide medical treatment to a critically injured or ill individual.

There are two categories of air ambulance services: fixed wing (airplane) and rotary wing (helicopter) aircraft. The higher operational costs of the two types of aircraft are recognized with two distinct payment amounts for air ambulance mileage. The air ambulance mileage rate is calculated per actual loaded (patient onboard) miles flown and is expressed in statute miles (not nautical miles).

FIXED WING AIR AMBULANCE (FW)(A0430)
Fixed wing air ambulance is furnished when the member’s medical condition is such that transport by ground ambulance, in whole or in part, is not appropriate. Generally, transport by fixed wing air ambulance may be necessary because the member’s condition requires rapid transport to a treatment facility, and either great distances or other obstacles, e.g., heavy traffic, preclude such rapid delivery to the nearest appropriate facility. Transport by fixed wing air ambulance may also be necessary because the member is inaccessible by a ground or water ambulance vehicle.

ROTARY WING AIR AMBULANCE (RW)(A0431)
Rotary wing air ambulance is furnished when the member’s medical condition is such that transport by ground ambulance, in whole or in part, is not appropriate. Generally, transport by rotary wing air ambulance may be necessary because the member’s condition requires rapid transport to a treatment facility, and either great distances or other obstacles, e.g., heavy traffic, preclude such rapid delivery to the nearest appropriate facility. Transport by rotary wing air ambulance may also be necessary because the member is inaccessible by a ground or water ambulance vehicle.

Any vehicle used as an ambulance must be designed and equipped to respond to medical emergencies and, in non-emergency situations, be capable of transporting members with acute medical conditions. The vehicle must comply with State or local laws governing the licensing and certification of an emergency medical transportation vehicle. At a minimum, the ambulance must contain a stretcher, linens, emergency medical supplies, oxygen equipment, and other lifesaving emergency medical equipment and be equipped with emergency warning lights, sirens, and telecommunications equipment as required by State or local law. Ambulances must be staffed by at least two people, with at least one of them certified by the State or local authority at the appropriate level of first aid training.
