c. Payments for the foregoing services, goods, and supplies furnished pursuant to this act shall be made to the extent authorized by this act, the rules and regulations promulgated pursuant thereto and, where applicable, subject to the agreement of insurance provided for under this act. The payments shall constitute payment in full to the provider on behalf of the recipient. Every provider making a claim for payment pursuant to this act shall certify in writing on the claim submitted that no additional amount will be charged to the recipient, the recipient's family, the recipient's representative or others on the recipient's behalf for the services, goods, and supplies furnished pursuant to this act.
No provider whose claim for payment pursuant to this act has been denied because the services, goods, or supplies were determined to be medically unnecessary shall seek reimbursement from the recipient, his family, his representative or others on his behalf for such services, goods, and supplies provided pursuant to this act; provided, however, a provider may seek reimbursement from a recipient for services, goods, or supplies not authorized by this act, if the recipient elected to receive the services, goods or supplies with the knowledge that they were not authorized.
