SB 363 California Senate · 2025-2026 Regular Session

Health care coverage: independent medical review.

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 establishes the Independent Medical Review System within each department, under which an enrollee or insured may seek review if a health care service has been denied, modified, or delayed by a health care service plan or health insurer and the enrollee or insured has previously filed a grievance that remains unresolved after 30 days. This bill would require a health care service plan or health insurer to annually report to the appropriate department the total number of claims processed by the health care service plan or health insurer for the prior year and its number of treatment denials or modifications, separated and disaggregated as specified, commencing on or before June 1, 2026. The bill would require the departments to compare the number of a health care service plan's or health insurer's treatment denials and modifications to (1) the number of successful independent medical review overturns of the plan's or insurer's treatment denials or modifications and (2) the number of treatment denials or modifications reversed by a plan or insurer after an independent medical review for the denial or modification is requested, filed, or applied for. For a health care service plan or health insurer with 10 or more independent medical reviews in a given year, the bill would make the health care service plan or health insurer liable for an administrative penalty, as specified, if more than 50% of the independent medical reviews filed with a health care service plan or health insurer result in an overturning or reversal of a treatment denial or modification in any one individual category of specified general types of care. The bill would make a health care service plan or health insurer liable for additional administrative penalties for each independent medical review resulting in an additional overturned or reversed denial or modification in excess of that threshold. The bill would require the departments to annually include data, analysis, and conclusions relating to these provisions in specified reports. Because a willful violation of these provisions by a health care service plan would be a crime, this bill would impose a state-mandated local program. Existing law creates the Managed Care Administrative Fines and Penalties Fund in the State Treasury for the deposit of fines and administrative penalties collected pursuant to provisions licensing and regulating health care service plans. This bill would create the Managed Care Independent Medical Review Administrative Penalties Subaccount in the Managed Care Administrative Fines and Penalties Fund for the receipt and deposit of moneys generated from the administrative penalties described above with respect to health care service plans. The bill would create the Health Insurance Independent Medical Review Administrative Penalties Fund in the State Treasury for the receipt and deposit of moneys generated from the administrative penalties described above with respect to health insurers. The bill would authorize the moneys in the Managed Care Independent Medical Review Administrative Penalties Subaccount and Health Insurance Independent Medical Review Administrative Penalties Fund to be expended, as specified, upon appropriation by the Legislature. This bill would declare that its provisions are severable. 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 April 10 amendment to SB 363 raises the penalty trigger threshold from 40% to 50% for independent medical review overturn rates, cuts all administrative penalty amounts in half (first violation drops from $50,000 to $25,000), removes the Medi-Cal managed care exemption, and eliminates the amendment to Section 130204 that would have required the Center for Data Insights and Innovation to report on treatment denial data. The bill was also restructured so that reporting requirements sit in one section and enforcement/penalty provisions in another.
ENFORCEMENT

The threshold at which a plan or insurer becomes liable for penalties increased from more than 40% to more than 50% of independent medical reviews resulting in an overturn or reversal in any single care category.

All administrative penalty amounts were halved: first violation reduced from $50,000 to $25,000; second violation range reduced from $100,000-$400,000 to $50,000-$200,000; subsequent violations reduced from $1,000,000 minimum to $500,000 minimum.

SCOPE

The exemption for Medi-Cal managed care plan contracts was removed, meaning the reporting and penalty provisions now apply to Medi-Cal plans as well.

The amendment to Section 130204 of the Health and Safety Code was deleted entirely. This had required the Center for Data Insights and Innovation to include independent medical review overturn data in its annual legislative report and required DMHC to provide related data to the center.

TECHNICAL

The penalty inflation adjustment mechanism changed from being based on average rate of change in premium rates for individual and small group markets (weighted by enrollment) to being based on the percentage change in the five-year calendar year average of the medical care index of the Consumer Price Index published by the U.S. Bureau of Labor Statistics.

The bill was restructured so that Section 1374.37 now contains only reporting requirements (denial data, total claims, deadlines) while Section 1374.38 contains the comparison methodology, violation determination, and penalty provisions. Previously these were combined in a single section.

DEFINITION

The specific diagnosis categories are now described as 'diagnosis category or subcategory as determined by the department,' with a new requirement that DMHC and DOI coordinate to ensure consistent categories across both departments, giving regulators more flexibility to update the list.

REQUIREMENT

A new denial reason category was added: 'Emergency or urgent care reimbursement,' in addition to the existing 'Urgent care' category.
