A. Any benefits payable to an injured employee under this act shall be reduced in an amount equal to, dollar-for-dollar, the amount of benefits the injured employee has previously received for the same medical services or period of disability, whether those benefits were paid under a group health care service plan, a group disability policy, a group loss of income policy, a group accident, health, or accident and health policy, a self-insured employee health or welfare benefit plan, or a group hospital or medical service contract; provided, however, such reduction does not apply to any benefit received from a group policy for disability if the injured employee has paid for the policy.

B. The claimant shall be required to disclose in a manner to be determined by the Commission the identity, address, or phone number of any person or entity which has paid benefits described in this section in connection with any claim under this act.
