New claim edit: Invalid Place of Service (POS) code

Dec 2, 2025

Stedi now rejects 837P professional and 837D dental claims with an invalid Place of Service (POS) code.

A Place of Service (POS) code tells the payer where the patient received care, such as a doctor’s office, a hospital, or the patient’s home.

POS codes are always two digits with no spaces. See Place of Service Code Set on CMS.gov for a list of valid POS codes and their descriptions.

Payers reject claims that contain invalid POS codes, such as a code that contains one digit without a leading zero. These rejections can cause delays. This edit – the industry’s term for an automated validation rule – prevents those claims from ever reaching the payer.

Rejection errors
If you submit a claim that fails the edit using Stedi’s institutional claim submission API, you’ll get back an error message in real time. If you’re using the JSON API endpoint, the response includes an error in the errors array:

{
  "errors": [
    {
      "code": "33",
      "description": "The place of service code, 1, is invalid. The code must be exactly 2 digits without any spaces. 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.
