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": [ { "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": [ { "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" } ] }
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
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
