Stedi now rejects [837P professional](https://www.stedi.com/docs/healthcare/submit-professional-claims) claims that include a property and casualty date of first contact without a related claim number.

## How the edit works

Property and casualty (P&C) insurance claims cover injuries from accidents or liability events like auto accidents, Workers' Compensation, personal injury, and liability cases. These claims go to a P&C insurer rather than a healthcare payer.

In P&C claims, the date of first contact notes when a healthcare provider first treated the patient for the injury.

**Property and casualty date of first contact**

The insurer opens an incident file and assigns a related claim number before it can process any billing.

If a P&C claim includes the date of first contact but not the claim number, the payer may reject the claim.

This [edit](https://www.stedi.com/docs/healthcare/claim-edits-and-repairs#edits) catches the issue before the claim reaches the payer. It prevents payer rejections, which are slower and delay payment for the provider.

## Rejection errors

If you submit a claim using Stedi's [Claim Submission API endpoints](https://www.stedi.com/docs/healthcare/intro-to-claim-submission#api-claim-submission) and the claim fails the edit, you'll get back an error response in real time. The response includes details in the `errors` array.

      "followupAction": "Please Correct and Resubmit"
    }
  ]
}
```

If you submit a claim using [SFTP](https://www.stedi.com/docs/healthcare/submit-claims-sftp-connection) and the claim fails the edit, Stedi will reject the claim with a [277CA claim acknowledgment](https://www.stedi.com/docs/healthcare/claim-responses-overview#277ca-claim-acknowledgment). The acknowledgment will include a related [claim status category code](https://x12.org/codes/claim-status-category-codes), [claim status code](https://x12.org/codes/claim-status-codes), and error message.
