Air Ambulance Services
10.4 - Air Ambulance Services
(Rev. 103; Issued: 02-20-09; Effective Date: 01-05-09; Implementation Date: 03-
20-09)
Medically appropriate air ambulance transportation is a covered service regardless of the
State or region in which it is rendered. However, A/B MACs (A) and (B) approve claims
only if the beneficiary’s medical condition is such that transportation by either basic or
advanced life support ground ambulance is not appropriate.
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).
1. Fixed Wing Air Ambulance (FW)
Fixed wing air ambulance is furnished when the beneficiary’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 beneficiary’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
beneficiary is inaccessible by a ground or water ambulance vehicle.
2. Rotary Wing Air Ambulance (RW)
Rotary wing air ambulance is furnished when the beneficiary’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 beneficiary’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
beneficiary is inaccessible by a ground or water ambulance vehicle.
