W. Va. Code § 16-29D-5: Coordination of benefits.

Coordination of benefits is permitted between two or more insurance contracts or employee benefit plans and shall be included for benefits from the Public Employees Insurance Agency and, as appropriate, from the state Medicaid program, the workers' compensation fund and the Division of Rehabilitation Services. Notwithstanding the foregoing, the workers' compensation fund shall be considered the primary payor for health care services related to work-related injuries and diseases ruled compensable as provided in article four, chapter twenty-three of this code. In no event shall the state Medicaid program be considered a primary insurance contract.
