(1) If a claimant is receiving disability or rehabilitation compensation benefits and the claimant receives social security retirement benefits or is eligible to receive or is receiving full social security retirement benefits or retirement benefits from a system that is an alternative to social security retirement, the claimant is considered to be retired. When the claimant is retired, the liability of the insurer is ended for payment of permanent partial disability benefits other than the impairment award, payment of permanent total disability benefits, and payment of rehabilitation compensation benefits. However, the insurer remains liable for temporary total disability benefits, any impairment award, and medical benefits.
(2) If a claimant who is eligible under subsection (1) to receive retirement benefits and while gainfully employed suffers a work-related injury, the insurer retains liability for temporary total disability benefits, any impairment award, and medical benefits.
