Prior authorization program for repetitive scheduled non-emergent ambulance transports

CMS began operating the repetitive scheduled non-emergent ambulance transports (RSNAT) prior authorization (PA) program in limited states in 2014 under the authority of the Social Security Act. In subsequent years, the Medicare Access and CHIP Reauthorization Act of 2015 required that the model expand to all states if such an expansion met certain criteria outlined in the Act. The model has met all nationwide criteria, and CMS has received final approval to expand the model nationwide. In April 2022 this program was implemented for providers in First Coast’s jurisdiction:
By submitting a completed coversheet 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.
A repetitive ambulance service is defined as a medically necessary ambulance transportation that is furnished three or more times during a 10-day period, or at least once per week for at least 3 weeks (round trips).
The model 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
HCPCS code A0425 is considered an associated service and will not receive prior authorization.
Note: Ambulance suppliers under review by a unified program integrity contractor (UPIC) are not eligible to submit prior authorization requests (PARs).
Prior authorization should ideally be requested prior to rendering transports. The PAR must include all documentation necessary to show that the service meets applicable Medicare coverage, coding, and payment rules.
Note: This form is available for submission through our secure internet portal SPOT. If you do not have a SPOT account,

Prior authorization is voluntary, however if the ambulance provider elects to bypass prior authorization, First Coast will stop an applicable claim for prepayment review if submitted without a prior authorization request decision.
Note: Effective January 9, 2025, CMS will be removing the expedited review request. Refer to
Change Request (CR) 13711 for complete details on the change.
MACs may now allow up to 240 one-way trips in a 180-day period per prior authorization request for beneficiaries with chronic conditions that are deemed not likely to change over time and meeting all Medicare requirements for repetitive non-emergent ambulance transport. The medical records must clearly indicate the condition is chronic. In addition, two previous prior authorizations requests must have established that the beneficiary’s medical condition has not changed or has deteriorated from previous requests before the MACs may allow an extended affirmation period.
• The decision to allow an extended affirmation period is at MAC discretion. Ambulance suppliers cannot request transports beyond the current maximum of 80 transports per 60-day period.
• Ambulance suppliers are responsible for always maintaining a valid physician certification statement (PCS).
• The MACs reserve the right to request the PCS at any time.
• Each individual time a patient is transported by ambulance, that transport must be reasonable and necessary regardless of whether a new prior authorization is required.
Reminder: UTNs are required on corresponding claims –
