Official Summary Text

AB 539, as amended, Schiavo.
Health care coverage: prior authorizations.
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 provides that a health care service plan or a health insurer that authorizes a specific type of treatment by a health care provider shall not rescind or modify this authorization after the provider renders the health care service in good faith and pursuant to the authorization.
This bill would require a prior authorization for a health care service by a health care service plan or a health insurer to remain valid for a period of at least one year from the date of
approval.
approval, or throughout the course of prescribed treatment, if less than one year.
Because a violation of the bill by a health care service plan would be a crime, the 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.
