Significant clustering of health care utilization rates for Medicare beneficiaries with CWP was observed in the central Appalachian states of Kentucky, West Virginia, and Virginia. Significant clustering of health care utilization rates for Medicare beneficiaries with Other Related Pneumoconiosis was observed in Appalachia and the southeast parts of Texas and Louisiana. This clustering merits additional research to understand underlying disease etiology
