New claim edit: Invalid tax identification number
Dec 2, 2025
Stedi now rejects 837P professional, 837D dental, and 837I institutional claims that contain an invalid tax identification number (TIN) for the billing provider.
When you submit a claim, you must include the billing provider’s TIN – either a Social Security Number (SSN) or Employer Identification Number (EIN). The TIN must be a 9-digit number with no spaces or separators.
Payers reject claims that contain an invalid TIN for the billing provider, which can cause delays.
This edit – the industry’s term for an automated validation rule – catches the issue before it reaches the payer.
Rejection errors
If you submit a claim that fails the edit using Stedi’s claim submission APIs or professional claim form, you’ll get back an error message in real time. If you’re using a JSON API endpoint, the response includes error details in the errors array:
{ "errors": [ { "code": "33", "description": "The billing provider tax id (TIN), 1234567890, is invalid. The TIN must be a string of exactly 9 numbers with no separators. Correct and resubmit.", "followupAction": "Please Correct and Resubmit" } ] }
If you submit a claim that fails the edit using SFTP, Stedi will reject the claim with a 277CA claim acknowledgment. The acknowledgment will contain a related claim status category code, claim status code, and error message. You can use the error message to correct and resubmit the claim.
