What AB 1570 does, verified May 18, 2026
The bill aims to expand health care coverage in California by requiring health care service plans, insurance policies, and self-insured employee welfare benefit plans to cover diagnostic imaging services without cost sharing. This includes screening mammography and medically necessary diagnostic breast imaging for certain individuals, such as those with a risk factor associated with breast cancer. The bill also provides coverage without cost sharing for diagnostic imaging following an abnormal mammography result. The state is not required to reimburse local agencies and school districts for costs associated with implementing this new coverage.

LEGISLATIVE COUNSEL'S DIGEST
AB 1570, as amended, Wilson. Health care coverage: diagnostic imaging.
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 policy of health insurance that provides hospital, medical, or surgical coverage, 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.
