SB 1037: Health care coverage: rate review.
What SB 1037 does, verified September 28, 2026
The bill aims to amend health and insurance laws to improve rate review and affordability. It would redefine "unreasonable rate increase" to mean a rate hike determined by the director of the department of managed health care or the insurance commissioner as excessive, unjustified, unfairly discriminatory, or unreasonable. The bill would require health plans and insurers to demonstrate the impact of health care cost targets on rate development, including medical trends, inflation, and administrative costs. Plans and insurers must reconcile their cost drivers with analysis published by the office of health care affordability.

CALIFORNIA LEGISLATURE— 2025–2026 REGULAR SESSION
Senate Bill
No. 1037
| Introduced by Senator Weber Pierson |
February 11, 2026 |
An act to amend Sections 1385.01 and 1385.035 of the Health and Safety Code, and to amend Sections 10181 and 10181.35 of the Insurance Code, relating to health care coverage.
LEGISLATIVE COUNSEL'S DIGEST
SB 1037, Weber Pierson. Health care coverage: rate review.
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.
The people of the State of California do enact as follows:
