N263 Remark Code: Operating Provider Secondary ID

What N263 means

A facility claim that includes surgery identifies the operating surgeon by NPI. Certain payers additionally want a second identifier for that surgeon, typically a state license number or a number the payer assigned at enrollment, each preceded by a qualifier that says what kind of ID it is. N263 is the payer telling you that second identifier did not pass.

Paired with CARC 16, it is a request for corrected data rather than a coverage denial.

Common causes

• The payer’s rule requiring a secondary ID for surgeons was never added to your claim setup.
• The qualifier did not match the number (for example, a license number labeled as a payer ID).
• The license number was from a different state than the one where surgery was performed.
• The surgeon’s license was renewed under a new number, or the payer issued a new proprietary ID.
• The number was keyed with extra characters such as dashes or state prefixes the payer doesn’t accept.

What to do

1. Check the payer’s companion guide for exactly which operating provider secondary ID it requires and in what format.
2. Get the current number from the surgeon’s credentialing file or from the payer.
3. Enter it, with the right qualifier, in the surgeon’s payer-specific setup.
4. Send a replacement claim (frequency code 7) with the original claim number.
5. If you are unsure what the payer has on file, call provider services before resubmitting so you don’t repeat the denial.

How to prevent it

Treat secondary identifiers as payer-specific attributes with expiration dates. Credentialing already tracks license renewals, so connect that calendar to the billing provider file. Reviewing remits by remark code, as described in our CARC and RARC analysis guide, shows quickly whether N263 is isolated to one surgeon or a payer-wide setup gap.
