4073.5.
(a) A pharmacist filling a prescription order for a prescribed biological product may select a biosimilar only if both of the following conditions are met:(1) The product selected as a biosimilar has been approved by the federal Food and Drug Administration (FDA) under the 351(k) pathway of the federal Public Health Service Act (42 U.S.C. Sec. 262(k)) and has been determined to be interchangeable with the prescribed biological product.
(2) The
prescriber does not personally indicate “Do not substitute,” or words of similar meaning, in the manner provided in subdivision (c).
(b) For prescriptions filled prior to January 1, 2017, the pharmacy shall, within five business days of the selection of a biological product or an interchangeable biosimilar, approved as provided in paragraph (1) of subdivision (a), notify the prescriber whether the prescription dispensed was a biological product or an interchangeable biosimilar, approved as provided in paragraph (1) of subdivision (a), or enter the information in a patient record system shared by the prescriber. No notification is required if the prescriber indicates “Do not substitute” in the manner provided in subdivision (c), if there is no FDA-approved interchangeable biosimilar pursuant to paragraph (1) of subdivision (a), or if a refill prescription is not changed from the product originally dispensed.
(c) In no case shall a selection be made pursuant to this section if the prescriber personally indicates, either orally or in his or her own handwriting, “Do not substitute,” or words of similar meaning. Nothing in this subdivision shall prohibit a prescriber from checking a box on a prescription marked “Do not substitute,” provided that the prescriber personally initials the box or checkmark. To indicate that a selection shall not be made pursuant to this section for an electronic data transmission prescription as defined in subdivision (c) of Section 4040, a prescriber may indicate “Do not substitute,” or words of similar meaning, in the prescription as transmitted by electronic data, or may check a box marked on the prescription “Do not substitute.” In
either instance, it shall not be required that the prohibition on substitution be manually initialed by the prescriber.
(d) Selection pursuant to this section is within the discretion of the pharmacist, except as provided in subdivision (c). The pharmacist who selects the biosimilar to be dispensed pursuant to this section shall assume the same responsibility for substituting the biosimilar as would be
incurred in filling a prescription for a biosimilar prescribed by name. There shall be no liability on the prescriber for an act or omission by a pharmacist in selecting, preparing, or dispensing a biological product pursuant to this section. In no case shall the pharmacist
select a biosimilar that meets the requirements of paragraph (1) of subdivision (a) unless the cost to the patient of the biosimilar selected is the same or less than the cost of the prescribed biological product. Cost, as used in this subdivision, is defined to include any professional fee that may be charged by the pharmacist.
(e) This section shall apply to all prescriptions, including those presented by or on behalf of persons receiving assistance from the federal government or pursuant to the Medi-Cal Act set forth in Chapter 7 (commencing with Section 14000) of Part 3 of Division 9 of the Welfare and Institutions Code.
(f) When a selection is made pursuant to this section, the substitution of a biosimilar shall be communicated to the patient.
(g) The board shall maintain on its public Internet Web site a link to the current list, if available, of biosimilar products determined by the FDA to be interchangeable, as provided in paragraph (1) of subdivision (a).
(h) For purposes of this section, the following terms shall have the following meanings:
(1) “Biological product,” “biosimilar,” and “interchangeable” have the
same meanings that apply to those terms under Section 351 of the federal Public Health Service Act (42 U.S.C. Sec. 262).
(2) “Prescription,” with respect to a biological product, means a prescription for a product that is subject to Section 503(b) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. Sec. 353(b)).
(3) “351(k) pathway” refers to the licensure of a biological product as a biosimilar or an interchangeable biosimilar by the FDA pursuant to Section 351(k) of the federal Public Health Service Act.
(i) Nothing in this section prohibits the administration of immunizations, as permitted in Section 4052.
(j) Nothing in this section prohibits a disability insurer or health care service plan from requiring prior authorization or imposing
other appropriate utilization controls in approving coverage for any biological product.
