Prior authorizations

Prior authorization program
CMS sponsors a variety of programs intended to safeguard beneficiary access to medically necessary items and services while reducing improper Medicare billing and payment. Prior authorization (PA) serves as a screening mechanism to help CMS ensure continued compliance with Medicare coverage requirements.
Under prior authorization, the provider or supplier submits the prior authorization request and supportive medical documentation to the MAC and receives an affirmed or non-affirmed decision prior to rendering the service. These initiatives do not change any medical necessity or documentation requirements.

Active initiatives
Effective March 18, 2022, CMS will prior authorize certain repetitive scheduled non-emergent ambulance transports for dates of service on or after April 1, 2022, in Florida, Puerto Rico and the U.S. Virgin Islands.
By submitting a completed cover sheet pdf file and the required documentation, a supplier can receive provisional prior authorization for as many as 40 round trips (80 one-way transports) in a 60-day period.
The PA program for RSNAT services includes the following HCPCS codes:
A0426 - Ambulance service, advanced life support, non-emergency transport, level 1 (ALS1)
A0428 - Ambulance service, basic life support (BLS), non-emergency transport
