DCMWC Announcement: Modernizing Payment of Medical Benefits

Notice of Final Rule
The Office of Workers' Compensation Programs has issued a Final Rule governing the Black Lung Disability Trust Fund's payment of medical benefits under the Black Lung Benefits Act. The Final Rule:

  1. Adopts modern payment formulas for physicians, hospitals and other providers that are derived from the formulas used in the Medicare program. These formulas are also similar to those used by other OWCP programs (e.g., Federal Employees Compensation and Energy Employees Occupational Illness Compensation programs).
  2. Codifies the black lung program's current practices for the payment of prescription drugs and the submission of medical bills for payment.
  3. Provides greater clarity about fees paid to providers, which should speed processing and payment of benefits as well as make it easier for the Trust Fund to obtain reimbursement from coal companies.
  4. Prohibits providers from seeking additional payments from miners for covered services that have been paid by the Trust Fund.

Miners will not see any change in the medical care they receive to treat their black lung disease.
The regulations will be effective August 31, 2018. The rules will apply to medical equipment, prescription drugs, and inpatient medical services provided or rendered after that date. The rules governing payment of professional medical services and outpatient medical services have a delayed application date and will apply to services rendered after April 27, 2020.

The Final Rule is available for public inspection today on the Federal Register's website at: https://www.federalregister.gov/documents/2018/06/14/2018-12418/black-lung-benefits-act-medical-benefit-payments. The Federal Register published the rule on June 14, 2018. The published version is available online at the same website location.

DCMWC Announcement: Final Rulemaking on Medical Benefit Payments

On June 14, 2018, the Office of Workers' Compensation Programs Division of Coal Mine Workers' Compensation issued a final rule governing the Black Lung Disability Trust Fund's payment of medical benefits under the Black Lung Benefits Act. The revised regulations became effective on August 31, 2018. Most of them, including those governing payments for medical equipment, prescription drugs, and inpatient medical services, applied immediately. However, the regulations governing payment of professional medical services and outpatient medical services had a later applicability date of November 30, 2019, so that a new computer system could be developed to process these bills. OWCP is delaying the applicability date of the regulations governing payments for professional medical services and hospital outpatient services from November 30, 2019, to April 26, 2020, due to unforeseen delays in developing the computer system. More information is available at: https://www.dol.gov/owcp/dcmwc/

Important Notice Concerning Coverage of Lung Transplants by the Federal Black Lung Program

The Division of Coal Mine Workers' Compensation, or Federal Black Lung Program, requires prior approval of the pre-transplant evaluation for lung transplants and the lung transplant itself for Black Lung beneficiaries (20 C.F.R. § 725.705).

Information about an individual's general eligibility for medical benefits may be obtained by calling the District Office where the patient's claim file is located, or by calling the Black Lung toll-free number at (800) 638-7072. Eligibility for medical benefits does not automatically include approval for a pre-transplant evaluation or a lung transplant.

Before seeking approval for a pre-transplant evaluation or a lung transplant, a medical center must be approved as a lung transplant center by the Center for Medicare and Medicaid Services (CMS), or the request will automatically be denied. The list of approved transplant centers is available at:


After reaching the homepage, select the “Resources” link on the upper right hand of the page. A pop-up window will open. Select link for “List of CMS-Approved Organ Transplant Programs”. This will open an excel spreadsheet which contains certification information for all Medicare-certified transplant programs, organized by State. Please refer to the approved lung transplant programs.

Approved lung transplant centers must determine if the patient's medical benefits are the responsibility of a coal mine operator or insurer or the Black Lung Disability Trust Fund. The patient should have this information. For a pre-transplant evaluation or transplant to be considered, it must be necessitated by the coal miner's black lung condition and directly related conditions. If the patient is covered by an insurer or coal mine operator, the company's approval must be obtained prior to a pre-transplant evaluation or transplant. Pre-transplant evaluation and transplant coverage is decided on a case-by-case basis. The Federal Black Lung Program expects coal mine operators or insurers to provide the same coverage that it does. The documentation that coal mine operators or insurers require to determine whether or not they will approve coverage may vary.

If the patient is covered by the Black Lung Disability Trust Fund, the approval process must be initiated by emailing the request to https://owcpmed.dol.gov or by calling the toll-free number (800) 638-7072.

Requests for pre-transplant evaluations and lung transplants should include basic information including the patient's name and date of birth, as well as the name of the facility performing the evaluation or transplant.

Additionally, a request for a pre-transplant evaluation must include a physician's letter of justification. A physician's letter of medical justification is a well-rationalized narrative statement, prepared by a qualified physician who has been actively treating the patient for their pulmonary condition. The letter of medical justification represents the physician's independent assessment and opinion and must include a brief review of the claimant's pertinent medical history, a brief statement regarding the claimant's current medical condition, and explanation of the claimant's medical need for a lung transplant evaluation.

Requests for lung transplants must include the medical facility's lung transplant protocols and all medical records produced for the pre-transplant evaluation, including the results of all tests, consultations, and narrative reports.

After the Federal Black Lung Program evaluates the information submitted, it will notify the requestor of a determination regarding coverage. Any pre-transplant evaluation or transplant performed prior to receiving prior approval by the Federal Black Lung Program will be denied.

Any questions about pre-transplant evaluations or transplants should be directed to the Division of Coal Mine Workers' Compensation at efax-maos-transplant@dol.gov or by calling the toll-free number (800) 347-2502.


Effective January 1, 2022, in accordance with guidance set forth by the Centers for Medicare and Medicaid Services (CMS), DCMWC introduced two new pulmonary rehabilitation procedure codes, 94625 and 94626, to be billed for pulmonary rehabilitation services.

Effective July 1, 2022, the Healthcare Common Procedure Coding System (HCPCS) pulmonary rehabilitation procedure code G0424, will no longer be covered.

Please note that DCMWC will not pay for at-home pulmonary rehabilitation services.

Preauthorization is not required for in-facility pulmonary rehabilitation services.

Pulmonary rehabilitation providers must be enrolled in the DCMWC provider network to treat miners and receive payment for services. To enroll as a DCMWC provider, please access: the Web Bill Processing Portal<https://owcpmed.dol.gov/portal/> for enrollment instructions.

All bills for pulmonary rehabilitation services must be submitted on the OWCP-1500 claim form. A downloadable OWCP-1500 form<https://www.dol.gov/sites/dolgov/files/owcp/dfec/regs/compliance/owcp-1500.pdf> is available. Providers must use current procedure codes 94625 and 94626 when billing for pulmonary rehabilitation services. A bill for pulmonary rehabilitation services must include at least one of the following mandatory components:

1. Physician-prescribed exercise;
2. Education or training;
3. Psychosocial assessment;
4. Outcome's assessment; or
5. An individualized treatment plan.

DCMWC will pay for up to a maximum of 60 one-hour treatment sessions during any 90-day period; or a maximum of 90 one-hour sessions during any 12-month period. Lifetime maximums may also apply.

In accordance with 20 CFR 725.707(b), DCMWC may require reports of treatment from time to time, including an individualized treatment plan for each patient.

There is no change in the procedures for billing for other medical services that may be related to pulmonary rehabilitation services. For example, bills for established patient office visits and pulmonary function tests still do not require a Certificate Medical Necessity (CMN) and can be billed separately as they are now. There is also no change in the procedures for prescriptions for durable medical equipment (DME) or home nursing care, which will require a CMN.

All medical bills should be sent to:

DCMWC/Federal Black Lung Program
P.O. Box 8302
London, KY 40742-8302
