The Black Lung Clinic Programs primary goal is to reduce the morbidity and mortality associated with occupation related coal mine dust lung disease (CMDLD), also known as black lung disease, by providing: Medical services. Outreach services. Educational services. Benefits counseling services. All recipients are required to provide certain services to coal miners in their service area. We also provide additional requirements to the minimum required services, to make sure that the quality and breadth of services coal miners receive is sustained in all service areas.
