AB 1843: Communicable diseases: hepatitis C.

Official summary

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

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 also provides for the regulation of health insurers by the Department of Insurance. Existing law generally prohibits a health care service plan or health insurer from subjecting antiretroviral drugs that are medically necessary for the prevention of HIV/AIDS to prior authorization or step therapy.

This bill would prohibit a health care service plan and health insurer from subjecting direct-acting antiviral drugs that are medically necessary for the treatment of hepatitis C to prior authorization. The bill would specify that these provisions do not require a health care service plan or health insurer to cover all therapeutically equivalent versions without prior authorization, as specified. Because a violation of these provisions by a health care service plan would be a crime, this bill would impose a state-mandated local program.

The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that no reimbursement is required by this act for a specified reason.
