Prior Authorization Submission Updates in NMP
05/12/2026 | 09:34 AM
CMS has implemented several prior authorization programs in recent months, each with its own distinct requirements. To accommodate these variations, the Noridian Medicare Portal (NMP) was enhanced to offer a more streamlined, intuitive, and efficient submission process across all prior authorization programs.
The most critical update is ensuring the correct “Prior Authorization Type” is selected to accurately reflect the Prior Authorization Request (PAR) being submitted. Choosing the appropriate type helps prevent submission rejections, reduces processing delays, and ensures the request is routed to the correct Medical Review Team for timely review.
The Prior Authorization Type options include:
- Wasteful and Inappropriate Service Reduction (WISeR)
- Outpatient Hospital Department (OPD)
- Inpatient Rehabilitation Facility Review Choice Demonstration (IRF RCD)
- Ambulatory Surgical Center (ASC)
- Repetitive Scheduled Non-Emergent Ambulance Transport (RSNAT)
Note: Prior Authorization Type options available are dependent on the request’s line of business.
