AB 512 California Assembly · 2025-2026 Regular Session

Health care coverage: prior authorization.

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 disability insurers by the Department of Insurance. Existing law provides for the Medi-Cal program, administered by the State Department of Health Care Services and under which qualified low-income individuals receive health care services, including pursuant to contracts with various types of managed care plans. Existing law generally authorizes a health care service plan, including a Medi-Cal managed care plan, or disability insurer to use utilization review, under which a licensed physician or a licensed health care professional who is competent to evaluate specific clinical issues may approve, modify, delay, or deny requests for health care services based on medical necessity. For a request prior to or concurrent with the provision of health care services, existing law requires utilization review decisions to be made within 5 business days from the plan's or insurer's receipt of the information reasonably necessary and requested by the plan or insurer to make the determination, or within 72 hours if the enrollee or insured faces an imminent and serious threat to their health or the normal timeframe would be detrimental to their life or health, as specified. This bill would change the timeline for prior or concurrent authorization requests to no more than 3 business days from the plan's or insurer's receipt via electronic submission, or 5 business days from receipt via submission that is not electronic, of the information reasonably necessary and requested by the plan or insurer to make the determination. The bill would require a utilization review decision to be made within 24 hours from receipt of a prior or concurrent authorization request via electronic submission, or 48 hours from receipt via submission that is not electronic, if the enrollee or insured faces an imminent and serious threat to their health or the normal timeframe would be detrimental to their life or health. Because a willful violation of this provision by a health care service plan would be a crime, the bill would impose a state-mandated local program. The bill would exclude Medi-Cal managed care plans from the above-described timeline changes. 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
The Senate amendment modifies AB 512's utilization review timeline requirements by introducing a distinction between electronic and non-electronic submissions. Instead of the Assembly version's flat 48-hour standard and 24-hour urgent deadlines for concurrent authorization, the Senate version sets shorter deadlines (48 hours standard, 24 hours urgent) for electronically submitted requests while allowing longer deadlines (5 business days standard, 48 hours urgent) for non-electronic submissions. A new definition of 'electronic submission' is added, and the scope of the differentiated timeframe provisions is expanded to cover prior authorization requests in addition to concurrent ones.
REQUIREMENT

Concurrent (and now prior) authorization standard decisions: changed from a flat 48 hours to 48 hours for electronic submissions or 5 business days for non-electronic submissions

Concurrent (and now prior) authorization urgent decisions: changed from a flat 24 hours to 24 hours for electronic submissions or 48 hours for non-electronic submissions

DEFINITION

New definition of 'electronic submission' added: submission through an electronic portal designated by the plan, or an electronic submission in accordance with Section 130290 and applicable federal interoperability rules

SCOPE

The differentiated timeframe provisions (paragraphs covering non-urgent and urgent decisions) now explicitly apply to requests made 'prior to' the provision of health care services, not just concurrent requests

TECHNICAL

Paragraph numbering within subdivision (h) was reorganized; page numbers changed from 97 to 96; bill summary language updated to reflect the electronic vs. non-electronic distinction
