Rendering Provider NPI Update (Effective 2/16/2026)

What Changed?

In Service Center, the online claim form has been adjusted to change where the Rendering Provider NPI is shown.  

Before:

• Rendering Provider NPI was entered in Box 24J inside Stored Templates.

Now:

• The main Rendering Provider NPI must be entered in Box 33.  

• Box 24J now pulls from Stored Rendering Provider.

• Box 24J is only used when a service line has a different provider.

Simple Difference

• Box 33 = Provider for the entire claim.  

• Box 24J = Provider for one specific service line (only if different).

Most claims will only use Box 33.

Why You May Be Seeing an Error

The HCFA online claim form has changed. You must now enter the Rendering Provider NPI in a new location. If the NPI is saved in both the old and new locations, the claim will fail. This is a setup conflict. It is not a system error.

A claim will fail if:

• An NPI is saved in Stored Templates (old method), and

• An NPI is also saved in Stored Rendering Provider (new method).

The system detects two sources for the Rendering Provider. You must remove the old template entry.  

Follow the steps outlined in each step below to fix it.  

Part 1: Remove the Individual NPI from Old Stored Templates (Box 24J)

1. Once saved, the updated settings will immediately apply to that provider’s e-prescribing activity.  Log in to Service Center 2.0.  

2. Hover your mouse over Create Professional CMS 1500 Claim Form.

3. Click Start with Stored Data.

4. Click Select Stored Templates.  

5. Click the Edit Pencil next to a template used for claims.

6. Scroll to Box 24J.

7. Delete any Individual NPI listed.

8. Leave Box 24J blank.

9. Click Save.

10. Repeat for every HCFA template.  

Do not store any Individual NPI in Box 24J inside Stored Templates.  

Part 2: Store the Individual NPI in Stored Rendering Provider

1. Hover your mouse over Create Professional CMS 1500 Claim Form.

2. Click Start with Stored Data.

3. Click Select Rendering Provider.

4. Click the Edit Pencil to edit the provider record.

5. Enter the correct 10-digit Individual NPI.

6. Confirm that the NPI contains numbers only.

7. Click Save.

8. Repeat for each provider.

Store the Individual NPI only in Stored Rendering Provider.

Part 3: Verify Box 33 Is Entered Correctly on the Claim

1. Hover your mouse over Create Professional CMS 1500 Claim Form.

2. Click Start with Stored Data.

3. Select the appropriate options: Select Payer, Select Patient, Select Billing Provider, Select Rendering Provider, Select Facility, and/or Select Stored Template.

4. Click Create Claim.

5. Confirm that the Rendering Provider NPI is present in Box 33.

6. Confirm it matches the provider who performed the services.

7. Leave Box 24J blank unless a service line has a different provider.

8. Submit the claim.

If one provider performed all services, do not enter anything in Box 24J.

Part 4: If the Claim Still Fails After Editing the Template

If claim submission errors continue:

1. Hover over Create Professional CMS 1500 Claim Form.

2. Click Start with Stored Data.

3. Click Select Stored Templates.

4. Delete the old HCFA template completely by clicking the trashcan icon.

5. Click Add New Template.

6. Build the template from scratch.

7. Do NOT enter or store the Individual NPI in Box 24J.

8. Click Save.

9. Confirm that the Individual NPI is stored only in Stored Rendering Provider.

10. Recreate the claim.

11. Submit the claim again.

Why Recreating the Template Fixes the Problem

Older templates may contain hidden settings from the previous workflow. Even after removing the visible NPI in Box 24J, background data can still conflict with the new claim format.

Creating a new template removes hidden legacy settings. This ensures that the claim follows the updated structure.

How to Prevent This in the Future

1. Store Individual NPIs only in Stored Rendering Provider.

2. Allow the system to populate the Stored Rendering NPI in Box 33.

3. Keep Box 24J empty in all Stored Templates.

4. Use Box 24J only when providers differ by service line.

5. Review templates regularly to confirm Box 24J is blank.

6. Verify all NPIs contain exactly 10 digits.  

In Review

• Box 33 = Main Rendering Provider for the claim.

• Box 24J = Only for different providers on specific service lines.

• Do not store NPIs in Stored Templates.

• Store NPIs only in Stored Rendering Provider.

• Rebuild old templates if errors continue.

Following these steps will prevent claim failures caused by duplicate or conflicting NPIs.
