Fee Schedule for Ambulances

The fee schedule applies to all ambulance services, including volunteer, municipal, private, independent, and institutional providers, such as hospitals, critical access hospitals (except when it is the only ambulance service within 35 miles), and skilled nursing facilities, for claims with dates of service on or after April 1, 2002.

The Centers for Medicare & Medicare Services (CMS) will require some ground ambulance organisations to collect and report cost, revenue, utilisation, and other data through the Medicare Ground Ambulance Data Collection System beginning January 1, 2022. (GADCS).

Ambulance services are covered by Medicare Part B; however, the Medicare beneficiary can only use this service if the following conditions are met.

1. The Beneficiary’s Actual Transportation Occurs In The Situation.

2. The Beneficiary Is Delivered To The Correct Location.

3. The beneficiary’s condition should be such that any other mode of transportation would be fatal.

4. The provider must meet all of the necessary criteria, such as vehicle, staffing, and transportation equipment.

Payment Rules for Ambulance Transportation Billing

Medicare-covered ambulance services are reimbursed using the Medicare Ambulance Fee Schedule, which can be found here.

1. A separate base payment and mileage payment should be made.

2. The service provider should cover the beneficiary’s transportation to the closest facility as well as other items and services related to transportation.

3. Payment for items used and service should not be separated.

Modifiers for the Ambulance Claim

Modifiers for ambulance services are formed by combining two alpha characters with significantly different origins and destinations. With the exception of X, which represents the origin or destination code, each alpha letter begins with an X.

The following are the origin and destination codes, as well as their descriptions:
