(a) No health insurer, in enrolling an individual or in making any payments for benefits to the individual or on the individual's behalf, shall take into account that the individual is eligible for or is provided medical assistance under a Medicaid Plan of this State or any other state.
(b) Where a state agency has been assigned the rights of an individual eligible for medical assistance under Title XIX of the federal Social Security Act [42 U.S.C. § 1396 et seq.] and such individual is covered for health benefits from a health insurer, no such health insurer shall impose requirements on the state agency that are different from requirements applicable to an agent or assignee of any other individual so covered.
