SB 1094: Prescription drugs.

Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

(1)The Pharmacy Law governs the practice of pharmacy in this state, including the permissible duties of licensed pharmacists. A knowing violation of the Pharmacy Law is a misdemeanor. Existing law authorizes a pharmacist to select an alternative biological product when filling a prescription order for a prescribed biological product if the alternative biological product is interchangeable, as defined, and the prescriber does not personally indicate in a specified manner that a substitution is not to be made.

This bill would additionally authorize a pharmacist to select an alternative biological product when filling a prescription order for a prescribed biological product if the alternative biological product is biosimilar to, as defined, or interchangeable with, the prescribed reference product, and the prescriber does not personally indicate in a specified manner that a substitution is not to be made. Because a knowing violation of this provision would be a misdemeanor, the bill would create a new crime, thereby imposing a state-mandated local program.

(2)Existing law, the Knox-Keene Health Care Service Plan Act of 1975, provides for the licensure and regulation of health care service plans by the Department of Managed Health Care, and makes a willful violation of the act a crime. Existing law provides for the regulation of health insurers by the Department of Insurance.

Existing law prohibits a health care service plan that covers prescription drug benefits from limiting or excluding coverage for a drug that was previously approved for coverage if an enrollee continues to be prescribed that drug and that drug is appropriately prescribed and considered safe and effective for treating the enrollee’s medical condition. Existing law specifies that these provisions do not preclude a prescribing provider from prescribing another drug covered by the plan that is medically appropriate for the enrollee or a generic drug substitution authorized by a pharmacist, as specified.

This bill would prohibit a health insurance policy that covers prescription drug benefits from limiting or excluding coverage for a drug that was previously approved for coverage if an insured continues to be prescribed that drug and the drug is appropriately prescribed, and is considered safe and effective for treating the insured’s medical condition. With respect to both health care service plans and health insurers, the bill would specify that these provisions do not prohibit a prescribing provider from prescribing a drug, biosimilar, or interchangeable biological product substitution authorized by a pharmacist, as described above. The bill would authorize a health care service plan, health insurer, or utilization review organization to require an enrollee or insured to try a biosimilar or interchangeable biological product in place of a prescribed reference product that is subject to continuing coverage by the plan or insurer if specified conditions are met. The bill would require a health care service plan contract or health insurance policy issued, amended, or renewed on or after January 1, 2027, that provides prescription drug benefits and maintains one or more drug formularies that include a reference product to include on the relevant formulary at least one biosimilar or interchangeable biological product licensed for the same reference product if the biosimilar has a lower net cost to the plan or insurer than the reference product. Because a violation of these provisions by a health care service plan would be a crime, the bill would impose a state-mandated local program.

(3)This bill would provide that its provisions are severable.
