AB 1843 California Assembly · 2025-2026 Regular Session

Communicable diseases: hepatitis C.

Summary
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.

What changed between versions

08/26/26 - Amended Senate AB1843 · 2 edits
MINOR
The changes between these two versions are primarily formatting and presentation differences, reflecting a transition from a plain-text bill document to a web-scraped version from the California legislature website. The substantive legislative content - prohibiting prior authorization for hepatitis C direct-acting antiviral drugs - remains unchanged. A minor section renumbering occurred (Health and Safety Code 1342.77 to 1342.78, Insurance Code 10123.1937 to 10123.1938), likely due to another bill claiming the original numbers.
TECHNICAL

Section numbers were renumbered: Health and Safety Code section changed from 1342.77 to 1342.78, and Insurance Code section changed from 10123.1937 to 10123.1938. The actual provisions (prohibiting prior authorization for hepatitis C direct-acting antiviral drugs, the therapeutic equivalent exception, and the Medi-Cal managed care exemption) are unchanged.

The document format changed from a plain-text legislative bill to a web page version with navigation elements, search functionality, and metadata. No policy content was altered.
