Effective August 24, 2024, the Division of Coal Mine Workers’ Compensation (DCMWC) will initiate a recoupment process in conjunction with the Treasury Department to recover outstanding provider debts owed to the Federal Black Lung Program.

Currently, the Federal Black Lung Program automatically recoups the full amount owed from current and future provider payments until the debt is paid in full.

On or after August 24, 2024, if the debt remains unpaid after 120 days from the Remittance Voucher (RV) overpayment notice, the account balance will be sent to the Centralized Receivables Service (CRS) for collections.

If you have an inquiry or concern regarding the Remittance Voucher (RV) overpayment notice, please submit the RV overpayment notice and all supporting documentation to the following address:

Division of Coal Miner Workers’ Compensation (DCWMC)

P.O. Box 8307

The Division of Energy Employees Occupational Illness Compensation (DEEOIC) does not accept payments made by mail. All providers must submit an adjustment (corrected bill) to ensure that the overpayment created is properly reflected as an account receivable by DEEOIC. Once the account receivable is established, providers will receive a debt letter and instructions on how to service the account receivable from the Treasury's Centralized Receivables Service (CRS). For more information click here and refer to the section titled "How to Submit Refunds of Overpayments".

Effective June 1, 2024, the Office of Workers’ Compensation Programs (OWCP) will implement updates for adjustment/void processing.

For the Division of Federal Employees’ Compensation (DFEC), providers will no longer be allowed to submit bill void transactions.

• Providers wishing to return funds have the option to mail the refund along with an Adjustment Request template as the coversheet.
• For assistance in viewing the PDF, please select this link: How to view PDFs using Adobe Reader

For the Division of Coal Mine Workers’ Compensation (DCMWC), providers will have the new option to submit bill adjustments using the WCMBP portal.

• You may refer to the Bill Adjustment tutorial for further information.

For the Division of Energy Employees Occupational Illness Compensation (DEEOIC), there are no changes in the current process for adjustment requests.

Effective June 1, 2024, the Office of Workers’ Compensation Programs (OWCP) will implement an enhancement to prevent overpayments created from denied adjustment requests. 

On or after June 1, 2024, if an adjustment is submitted on a bill that has already been paid but subsequently denied in its entirety, the denial will be reflected on the Remittance Advice (RV), and the bill inquiry screen will display a status of denied.

In such cases, when providers seek payment reconsideration for the denied bill, it is essential to submit the adjustment request using the previously paid bill. This ensures that the adjustment is correctly associated with the original bill and facilitates the review process for payment reconsideration.

Providers are encouraged to use the Bill Inquiry and Bill Adjustment features of the Workers’ Compensation Medical Bill Processing (WCMBP) Portal https://owcpmed.dol.gov/ to review bill history.

Effective April 20, 2024, the Office of Workers’ Compensation Programs (OWCP) Division of Federal Employees’ Compensation (DFEC) will implement a recoupment process for providers’ outstanding debts.

Providers may have partial or full payment amounts applied to existing overpayments until the full overpaid amount is satisfied and all debts are closed.

Providers can refer to the remittance voucher (RV) for overpayment summary, recoupment summary, and recoupment details. A Remittance Voucher User Guide is available for an explanation on how to read the sections in the RV.

In addition, providers can also use the View Accounts Receivable feature after logging in to the Workers’ Compensation Medical Bill Processing (WCMBP) portal OWCP Connect (dol.gov). Providers can filter or sort results on the Accounts Receivable (AR) List to identify overpayment history, verify remaining debt balance owed, and review accounts receivable details by clicking on the AR Number.

Annual 1099s balances will be updated to reflect all recoupments.

The fee schedule calculator is a tool used to estimate the maximum allowable amount for services rendered and billed on the OWCP 1500 Professional form or the ADA Dental form. It is important to note:

• While the fee schedule calculator tool estimates payment, it does not guarantee eligibility or coverage for your specific service.
• The fee schedule calculator tool will not advise if services are appropriate for the accepted condition and will not confirm if authorization is required. Please use the Claimant Eligibility Inquiry and Authorization Submission features to verify this information.

Please refer to the Fee Schedule Calculator Quick Reference Guide for step-by-step instructions.

Effective December 9, 2023, the DFEC Program for Office of Workers’ Compensation Programs (OWCP) will enhance bill processing to automatically reprocess previously submitted bills that denied when the injured or ill worker’s case was under development, after the case is later accepted as payable by OWCP.

On December 9, 2023, a one-time courtesy bill reprocessing will occur for claimant cases that were adjudicated by DFEC, and accepted conditions assigned in the previous four weeks.

Afterwards, bills denied after December 9, 2023, will be automatically reprocessed if the case is accepted as payable.

Please note that additional denial EOBs may post during reprocessing. For example, if denials post for authorization of services related to accepted conditions, then providers are encouraged to request authorization for the billed service(s).
