UTN Unique Tracking NumberUTN (Unique Tracking Number)
The 14-character number the DME MAC assigns to a prior authorization decision; it must be on the claim, and on any resubmission, to link them.
A Unique Tracking Number (UTN) is the 14-character identifier printed on every DMEPOS prior authorization decision letter, affirmed or non-affirmed. It is how the MAC's claim system connects a claim to the PA decision that preceded it. Without it, a claim for an item on the Required Prior Authorization List cannot be matched to its affirmation and is denied.
On a paper CMS-1500 the UTN goes in the first 14 positions of Item 23. On an electronic claim it goes in loop 2300 or loop 2400, REF02 with REF01 equal to G1. When you resubmit a non-affirmed request, include the prior UTN so the reviewer can see the history. A UTN can also travel with the beneficiary between suppliers and between jurisdictions.
Common questions
Where do I find the UTN?
On the decision letter from the DME MAC, whether the decision was an affirmation or a non-affirmation. The MAC portal shows it as well.
Do I put the UTN on a claim after a non-affirmation?
Yes. If you deliver the item and bill after a non-affirmation, the claim still carries the UTN from that decision so the MAC can process the denial and preserve your appeal rights.
