Prior Authorization for DMEPOS

Your voice matters!

Prior authorization helps DMEPOS suppliers make sure they meet Medicare coverage, payment, and coding rules before they deliver the items. The DME MAC will review the medical documentation and send an affirmed or non-affirmed decision. See the Supplier Manual Chapter 9 – Coverage and Medical PolicyPDF for more information and background about the program.

How to Send Your Request

Affirmed & Non-Affirmed Decisions

Affirmed decisions are valid for a certain length of time, depending on the category. When the prior authorization is affirmed, the supplier must deliver the item within the listed timeframe (see table above). If the item is not delivered within the time limit, the supplier will need to send another request.

We will send decision letters to the supplier and the beneficiary. You may also request a copy of the letter to be sent to the physician.

The letter will include the Unique Tracking Number (UTN). The decision and UTN stays with the beneficiary. A supplier may transfer the UTN to another supplier per privacy laws.

Add the UTN to Your Claim

Add the UTN in Item 23 of the CMS-1500 Claim Form.

For electronic claims, add the UTN in either the 2300 – Claim Information loop or 2400 – Service Line loop in the Prior Authorization reference (REF) segment where REF01 = "G1" qualifier and REF02 = UTN.
