Claim edit: Invalid NPI format

Stedi now rejects 837P professional, 837D dental, and 837I institutional claims that contain a National Provider Identifier (NPI) with an invalid format.

How the edit works

An NPI is a unique, 10-digit identifier assigned to every healthcare provider in the U.S.

HIPAA-adopted X12 standards require that all NPIs in a claim be 10 digits. If a claim includes an NPI that’s not 10 digits – such as an NPI that’s too short or too long – the payer may reject the claim. This can delay payment for the provider.

This edit – the industry term for an automated validation rule – catches the issue before the claim reaches the payer.

Rejection errors

If you submit a claim using Stedi's Claim Submission API endpoints and the claim fails the edit, you'll get back an error response in real time. The response includes details in the errors array:

{
  "errors": [
    {
      "code": "33",
      "description": "Invalid NPI. The Billing Provider NPI of 123456789 is invalid. The National Provider Identifier must be valid with 10 digits and no prefixes or dashes. Correct and resubmit.",
      "followupAction": "Please Correct and Resubmit"
    }
  ]
}

If you submit a claim using SFTP and the claim fails the edit, Stedi will reject the claim with a 277CA claim acknowledgment. The acknowledgment will include a related claim status category code, claim status code, entity identifier code, and error message:

STC*A7>562>85*[DATE]*U*[AMOUNT]******A7>569>85**Invalid NPI. The Billing Provider NPI of 123456789 is invalid. The National Provider Identifier must be valid with 10 digits and no prefixes or dashes. Correct and resubmit.~

Tip: How to handle 15-digit NPIs

Some official NPI documentation references a 15-digit NPI format that includes a 5-digit card issuer prefix. Omit this card issuer prefix when submitting claims.
