You can now revise and resubmit [837P professional claims](https://www.stedi.com/docs/healthcare/submit-professional-claims) using the Stedi portal’s [CMS-1500 form](https://www.stedi.com/docs/healthcare/submit-professional-claims-ui#cms-1500-claim-form).

The CMS-1500 form is our online submission form for 837P professional claims. It mirrors the CMS-1500 Health Insurance Claim Form, also called the HCFA, the standard paper form for professional claims. Each field is numbered to line up with the CMS-1500 boxes. It’s designed to feel familiar to provider staff or anyone who already works with the CMS-1500.

Previously, if you submitted a claim using Stedi’s CMS-1500 form and later needed to fix it, you had two options:

- Re-enter all the data into the form by hand.

- Use the portal’s [Edit and resubmit feature](https://www.stedi.com/blog/edit-and-resubmit-claims-in-the-stedi-portal) to change the raw X12.

Now, you can revise the previous claim directly in Stedi’s CMS-1500 form. Stedi loads the data from the original claim into the form for you.

## Revise and resubmit a professional claim using the form

1.  In the Stedi portal, go to the **Transactions** page and open the claim you want to revise.

2.  Click **Edit and resubmit**.

3.  Select the new **1500 resubmission** option.

Make your changes, then resubmit. Use **Box 22 – Resubmission code** to show whether you’re replacing or cancelling the previous claim and provide the [Payer Claim Control Number (PCCN)](https://www.stedi.com/docs/providers/providers-review-resubmit-claims#find-existing-pccn) for the original claim.
