Effective August 9, 2025, the Office of Workers’ Compensation Programs (OWCP) will require group practices to include the servicing or rendering provider National Provider Identifier (NPI) when billing a professional claim. In addition, group practices must ensure the submitted servicing or rendering NPI is associated with an active servicing provider in the OWCP provider file.

Billing

Please follow the steps below to ensure the servicing NPI is submitted on the bill.

Please note that this requirement is not applicable to providers enrolled as individuals, facilities, or non-medical providers. This requirement is also not applicable to institutional or dental bills.

• Online (Direct Data Entry DDE): Servicing provider information can be entered on professional bills as the rendering provider in the Provider Information section or at the service line. Refer to the Enter Bills Online Tutorial for instructions and examples.
• Electronic Data Interchange (EDI): Servicing provider information is submitted in the Professional claim type Appendix A Loop 2310B for Rendering Provider information. Refer to the 837 Companion Guide for more details.
• Paper: Servicing provider information is entered in Box 24J of the service line on the OWCP 1500 Professional bill form. Refer to the Health Insurance Claim Form (OWCP-1500) instructions for more information.

Provider Enrollment

Professional bills from group practice providers received on or after August 9, 2025, will be denied if submitted without the servicing or rendering NPI, or if the submitted servicing or rendering NPI is not active in the group provider file.

Providers can review and, if needed, update the servicing provider information through the Workers’ Compensation Medical Bill Processing (WCMBP) portal https://owcpmed.dol.gov/, or by paper on the Provider Enrollment Application (OWCP-1168) Form.

• Online: Providers are encouraged to use the WCMBP portal OWCP Medical Bill Processing Portal (https://owcpmed.dol.gov) to review and update servicing provider NPI information. In addition, providers can review and confirm existing provider record information such as license information, contact information, and payment details. Instructions are available at: Updating Provider Information Resource Guide.
  Registration is required for WCMBP portal access. Providers can refer to the Provider Registration for Online Access (Updated 02/05/25) quick reference guide for more information.
