CMS began operating the RSNAT PA Model in limited states in 2014 under the authority of Section 1115A of the Act. The model tested whether PA of RSNAT services covered under Medicare Part B lowered program spending, while maintaining or improving the quality of care. The RSNAT PA Model began in the states of New Jersey, Pennsylvania, and South Carolina on December 1, 2014. Section 515(a) of the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) added Delaware, the District of Columbia, Maryland, North Carolina, Virginia, and West Virginia to the model on January 1, 2016.
Nationwide expansion of the RSNAT PA Model is planned for 2022. Effective December 1, 2021, states within Jurisdiction H (Arkansas, Colorado, Louisiana, Mississippi, New Mexico, Oklahoma, Texas) are now included in this initiative. Additional states will follow the schedule announced August 26, 2021, by CMS.
By submitting a complete cover sheet 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).
HCPCS code A0425 is considered an associated service and will not receive prior authorization.
Ambulance suppliers under review by a Unified Program Integrity Contractor (UPIC) are not eligible to submit prior authorization requests.
Ambulance service suppliers that bill Medicare Part B can receive provisional prior authorization in the JH jurisdiction (Arkansas, Colorado, Louisiana, Mississippi, New Mexico, Oklahoma, Texas).
Suppliers can receive prior authorization for up to 40 non-emergency scheduled round trips (A0426, A0428) or 80 one-way transports in 60 days. For scheduled trips beyond the prior authorized number, a second prior authorization request is required.
Effective with dates of service on or after December 1, 2021, prior authorization for certain repetitive scheduled non-emergent ambulance transports is now effective in JH states.
Submission of PARs can begin on November 17, 2021, for dates of service on or after December 1, 2021
Ambulance suppliers garaged in Arkansas, Colorado, Louisiana, Mississippi, New Mexico, Oklahoma, Texas

The purpose of the prior authorization program is to reduce improper payments, while maintaining or improving quality of care. It is designed to ensure all relevant coverage, coding, and medical record(s) requirements are met before the service is rendered to the beneficiary and the claim is submitted for payment.
Submit the prior authorization request. Attach the required medical records. Request decision notifications will be issued within 10 business days of receipt of submission. Resubmittal decision notifications will be issued within 10 business days of receipt. The notification will contain a 14-digit unique tracking number (UTN) that should be submitted in Item 23 on applicable claims.
For more information on coverage and documentation requirements, refer to:
The supplier must submit the PAR to us before the service is provided to the beneficiary and before the claim is submitted for processing. The PAR must include all documentation necessary to show that the service meets applicable Medicare coverage, coding, and payment rules.

Ambulance prior authorization requests on the incorrect form:
Only one round trip is being requested:
A supplier can receive provisional prior authorization for as many as 40 round trips (80 one-way transports) in a 60-day period. To save suppliers time on submitting the requests, we ask that you submit more than one round trip per request
To meet coverage criteria, the patient's medical record must contain documentation that fully supports the medical necessity for services.
The following submissions errors have been identified:
Origin and destination street address missing:
that do not contain the exact origin and destination street address. To process the prior authorization request, the exact origin and destination street address must be listed in the medical records summitted with the requests.
If the normal timeframe jeopardizes the life or health of the beneficiary, an expedited request can be submitted. However, if medical documentation does not support an expedited process, the request will be subject to the normal timeframe.
Request type: Expedite
If you selected "expedite", please explain why the normal time frame jeopardizes life or health of the beneficiary. Medical documentation must also support the need for an expedited review.
Complete all other required fields on the form.
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 maintaining a valid physician certification statement (PCS) at all times.
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.
