(a) Whenever a health insurance policy provides coverage that includes coverage for intravenously administered or injected chemotherapy medications which have been approved by the United States Food and Drug Administration for general use in the treatment of cancer, the policy shall not provide coverage or impose cost sharing for a prescribed, orally administered chemotherapy medication on a less favorable basis than the coverage it provides or cost sharing it imposes for intravenously administered or injected chemotherapy medications.

(b) A health insurance policy shall not increase cost sharing for chemotherapy medications in order to avoid compliance with subsection (a). A health insurance policy may increase cost sharing for chemotherapy medications if an increase is applied generally to other medical or pharmaceutical benefits administered in a similar health care setting under the contract.

(c) The prohibitions in subsections (a) and (b) do not preclude a health insurance policy from requiring an enrollee to obtain prior authorization before orally administered chemotherapy medication is dispensed to the enrollee. As part of prior authorization, an insurer may consider the medical necessity and cost of oral chemotherapy medications compared with intravenously administered or injected chemotherapy medication.

(d) This section shall apply to a high deductible health plan, as defined in section 223(c)(2) of the Internal Revenue Code of 1986 (Public Law 99-514, 26 U.S.C. § 223(c)(2)), only after the covered person's deductible has been satisfied for the year.

(e) This section shall apply to those health insurance policies issued or entered into or renewed on or after the effective date of this section.
