SB 1037 California Senate · 2025-2026 Regular Session

Health care coverage: rate 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 violation of the act by a health care service plan a misdemeanor. Existing law provides for the regulation of health insurers by the Department of Insurance. Existing law defines "unreasonable rate increase," for these purposes, to have the same meaning as in the federal Patient Protection and Affordable Care Act, which is that an unreasonable rate increase exists when the federal Centers for Medicare and Medicaid Services makes a determination that a rate increase is excessive, unjustified, or unfairly discriminatory, among other things. This bill would instead define "unreasonable rate increase," for the above-described purposes, to mean a rate increase that the Director of the Department of Managed Health Care or the Insurance Commissioner, as applicable, determines is excessive, unjustified, unfairly discriminatory, or otherwise unreasonable. Existing law requires a health care service plan or health insurer to submit rates to their regulating entity for review and to demonstrate the impact of any changes in the rate of growth of health care costs resulting from health care cost targets. This bill would instead require a health care service plan or health insurer to demonstrate the impact of health care cost targets and to demonstrate whether a health care service plan's or health insurer's annual rate growth exceeds or will exceed the cost target for the rating period. The bill would require, if a health care service plan's or health insurer's rate growth is expected to exceed the cost target for a rating period, the health care service plan or health insurer to include specified information in its rate filing, including, among other things, a detailed list of any proactive steps it is taking, or plans to take, for annual rate growth to meet the cost targets. Because a willful violation of these provisions by a health care service plan would be a crime, the bill would impose a state-mandated local program. Existing law requires the director or the commissioner, as applicable, in determining if a rate is unreasonable or not justified for purposes of the above-described review, to consider the impact on changes in health care costs as a result of the health care cost targets described above. This bill would delete those provisions and instead require the Department of Managed Health Care and the Department of Insurance to report on if rates, by plan or policy and in aggregate, meet the affordability standard, as defined, for an individual, a couple, and a family of four. The bill would require the report to include the annual change in premiums and cost sharing for the prior 5 years. The bill would, as part of the existing rate submission process, require a health care service plan or health insurer to provide information on premiums, deductibles, cost sharing, and any other factors specified by the department as necessary to complete the reports. 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 enrolled version of SB 1037 makes several substantive policy changes from the amended assembly version. Most significantly, it removes the requirement for regulators to analyze health plans' financial capacity (or insurers' surplus condition) when determining whether a rate increase is unreasonable, and shifts affordability evaluation from an individual rate review process to aggregate reporting. It also removes the tie to federal PPACA/CFR definitions for 'otherwise unreasonable' rate increases and eliminates the requirement for plans to reconcile their cost driver findings with Office of Health Care Affordability analyses.
REQUIREMENT

Removed the requirement for the Department of Managed Health Care director to consider a plan's financial capacity (tangible net equity, working capital, payouts to shareholders, reserves and investments) over the past three years when determining if a rate increase is unreasonable. Removed the parallel requirement for the Insurance Commissioner to consider an insurer's surplus condition.

Removed the provision that if a plan's financial capacity or an insurer's surplus condition was found to be excessive, the department must consider whether the entity could charge lower rates in determining if the proposed rate is unreasonable.

Affordability evaluation was moved from the individual rate review process to aggregate rate reports. Previously, the department had to evaluate affordability for an individual and family of four at 200%, 400%, and 800% of the federal poverty level as part of each rate review. Now the department reports on whether rates meet the affordability standard for an individual, a couple, and a family of four in aggregate reports under existing reporting sections.

Removed the requirement that if the Office of Health Care Affordability published an analysis on a specific cost driver and a plan or insurer used that cost driver to explain a rate increase, the entity must reconcile its findings to the extent they deviate from the OHCA analysis.

Removed the provision requiring the director or commissioner to consider the impact of changes in health care costs resulting from health care cost targets when determining whether a rate is unreasonable. This consideration was part of subsection (c) in both the Health and Safety Code and Insurance Code sections.

DEFINITION

The definition of 'unreasonable rate increase' no longer ties the 'otherwise unreasonable' prong to PPACA and 45 CFR Section 154.102 as in effect on January 1, 2026. It now simply states 'otherwise unreasonable' without a specific federal regulatory reference, giving state regulators broader discretion.

The 'affordability standard' definition changed from requiring that the plan contract's individual contribution to premium, share of premium, and deductible not exceed the amount described in Section 61020 of the Revenue and Taxation Code, to requiring that average gross premium and average deductible totals be less than the percent of income described in subdivision (a) of Section 61020.
