Stedi now rejects [837P professional](https://www.stedi.com/docs/healthcare/submit-professional-claims) claims that indicate an inpatient setting but are missing an admission date.

## How the edit works

In professional claims, an inpatient claim is a claim for services delivered to a patient who’s formally admitted to a hospital or similar facility.

Inpatient claims must include the patient's admission date. The date tells the payer when the patient was admitted to the facility for care.

**Admission date**

The place of service code identifies whether a claim is an inpatient claim. Codes such as `21` (Inpatient Hospital) or `51` (Inpatient Psychiatric Facility) indicate an inpatient setting.

If the place of service code indicates an inpatient setting and no admission date is present, 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.

```jsonc
{
  "errors": [
    {
      "code": "33",
      "description": "Missing Admission Date/Hour. The admission date/hour should be present on all inpatient claims and some outpatient claims. The submitted place of service, 21, indicates an inpatient claim. Correct and resubmit.",
      "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.

```jsx
STC*A7>189*[DATE]*U*[AMOUNT]******A8>249**Missing Admission Date/Hour. The admission date/hour should be present on all inpatient claims and some outpatient claims. The submitted place of service, 21, indicates an inpatient claim. Correct and resubmit.~
