SB 621: Health care coverage: biosimilar drugs.

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. Existing law provides for the regulation of health insurers by the Department of Insurance. Existing law authorizes a health care service plan or health insurer that provides coverage for prescription drugs to require step therapy if there is more than one drug that is clinically appropriate for the treatment of a medical condition, but requires a plan or insurer to expeditiously grant a step therapy exception request if specified criteria are met. Existing law does not prohibit a plan, insurer, or utilization review organization from requiring an enrollee or insured to try an AB-rated generic equivalent or interchangeable biological product before providing coverage for the equivalent branded prescription drug.

This bill would specify that a plan, insurer, or utilization review organization is also not prohibited from requiring an enrollee or insured to try a biosimilar before providing coverage for the equivalent branded prescription drug, but that the requirement to try biosimilar, generic, and interchangeable drugs does not prohibit or supersede a step therapy exception request.
