AB 1570 California Assembly · 2025-2026 Regular Session

Health care coverage: diagnostic imaging.

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 provides for the regulation of health insurers by the Department of Insurance. Existing law requires a health care service plan contract issued, amended, delivered, or renewed on or after January 1, 2000, or an individual or group policy of disability insurance or self-insured employee welfare benefit plan to provide coverage for mammography for screening or diagnostic purposes upon referral by specified professionals. Under existing law, mammography performed pursuant to those requirements or that meets the current recommendations of the United States Preventive Services Task Force is provided to an enrollee or an insured without cost sharing. This bill would require a health care service plan contract, a health insurance policy, or a self-insured employee welfare benefit plan issued, amended, or renewed on or after January 1, 2028, to provide coverage without imposing cost sharing for, among other things, screening mammography and medically necessary diagnostic breast imaging, including diagnostic breast imaging following an abnormal mammography result and for an enrollee or insured indicated to have a risk factor associated with breast cancer, except as specified. 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.

MODERATE
AB 1570 was amended in Assembly primarily to restructure the statutory subdivisions in both the Health and Safety Code and Insurance Code sections, add coauthors, and remove an explicit nonparticipating provider restriction from the basic mammography coverage provisions. The core policy - requiring no cost sharing for screening mammography and diagnostic breast imaging effective January 1, 2028 - remains unchanged. The restructuring clarifies which rules apply to base coverage versus the enhanced no-cost-sharing requirement.
SCOPE

The explicit restriction stating that enrollees/policyholders cannot receive basic mammography services from nonparticipating providers (unless referred by a participating provider) was removed from subdivision (a) of both Section 1367.65 and Section 10123.81. Out-of-network rules in subdivision (c) still govern the no-cost-sharing requirement.

The legislative digest was updated to explicitly list 'health insurance policy' as a covered plan type alongside 'a policy of health insurance that provides hospital, medical, or surgical coverage,' though the statutory text in Section 10123.81(b)(1) uses substantially the same language as before.

TECHNICAL

Both statutory sections were restructured: the old single subdivision (a) was split into (a)(1) for the base coverage requirement and (a)(2) for limitations, while the new no-cost-sharing provisions moved to subdivision (b). This is primarily an organizational change to improve clarity.

Ten coauthors were added: Assembly Members Caloza, Connolly, Davies, Haney, Ortega, Pacheco, Pellerin, Quirk-Silva, Michelle Rodriguez, and Aguiar-Curry.
