Remittance advice remark code

N290
Missing or invalid rendering provider identifier

What N290 means

The rendering provider's NPI is missing or not valid on the claim.

How to fix it

  1. Add the rendering provider's individual NPI
  2. Check the NPI is enrolled with the payer

Check the remark code (RARC) that came with the denial and the payer's own policy, since rules vary by payer and plan. This is a plain-English summary written by GetMax; the official code text is published by X12 at x12.org/codes.
