New claim edit: Invalid Social Security Number

Mar 3, 2026

Claims

Stedi now rejects 837P professional, 837D dental, and 837I institutional claims that contain an invalid Social Security Number (SSN).

How the edit works

SSNs can only contain 9 digits. If a claim contains an invalid SSN, the payer may reject the claim, which can delay payment for the provider.

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

Rejection errors

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

{
  "errors": [
    {
      "code": "33",
      "description": "Invalid Social Security Number. The submitted social security number does not meet the required format of 9 digits with no separators. Correct and resubmit.",
      "followupAction": "Please Correct and Resubmit"
    }
  ]
}

  "errors": [
    {

      "followupAction": "Please 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 include a related claim status category code, claim status code, entity identifier code, and error message:

STC*A7>148*[DATE]*HK*[AMOUNT]********Invalid Social Security Number. The submitted social security number does not meet the required format of 9 digits with no separators. Correct and resubmit
