What N613 means

N613 is a warning issued on a paid claim. The payer checked the ordering provider against its enrollment records and found a problem, such as a missing or outdated record, but let this claim through. The next one may not be.

What to do

  1. Check your data. Confirm the ordering provider’s name (box 17) and NPI (box 17b) match the order.
  2. If your data is wrong, correct your records so future claims carry the right provider.
  3. If your data is right, contact the ordering provider’s office and ask them to update their enrollment with the payer. In Medicare, that means their enrollment record, typically managed through PECOS.
  4. Track the provider until the update is confirmed, and hold non-urgent orders from them if the payer is about to enforce the edit.

See provider enrollment denials for more on ordering and referring enrollment.
