California SB 729: IVF Coverage, Eligibility, and Start Date

California Senate Bill 729 requires large-group health insurance plans in California to cover infertility diagnosis, fertility treatment, and in vitro fertilization for contracts issued, amended, or renewed on or after January 1, 2026. Coverage includes up to three completed egg retrievals with unlimited embryo transfers, and the law’s definition of infertility is written to include LGBTQ+ couples and single people who need medical help to conceive. It does not reach every plan in the state, so whether it applies to you depends on how your employer’s coverage is structured.

Which Plans Have To Comply

The mandate applies to large-group health care service plan contracts and large-group disability insurance policies — the fully insured employer plans covering 100 or more employees that are regulated by California’s Department of Managed Health Care (DMHC) or Department of Insurance (CDI).¹

Several categories of coverage are outside the mandate:

Self-insured employer plans. Because these are governed by federal ERISA law, California cannot regulate their benefit design. Many of the state’s largest employers self-insure, so this exemption reaches a substantial number of workers.
Small-group plans. Insurers must offer fertility coverage to small-group employers, but employers are not required to buy it, and employees on a small-group plan that declined the option have no benefit under SB 729.¹
Religious employers, as defined in California’s Health and Safety Code and Insurance Code.²
Medi-Cal managed care plans.
Specialized and limited-benefit policies, including accident-only, specified disease, hospital indemnity, and Medicare supplement coverage.³
CalPERS. Health benefit contracts under the California Public Employees’ Retirement System are not required to comply until July 1, 2027.

If you work for a religious employer or a company with a self-insured plan, the law does not help you directly. Some self-insured employers offer fertility benefits voluntarily, and individual-market coverage or out-of-pocket payment remain the alternatives.

Who Counts as Infertile Under the Law

SB 729 recognizes three separate paths to a fertility diagnosis, and meeting any one of them is enough.¹

A licensed physician determines you are infertile based on your medical, sexual, and reproductive history, age, physical exam, diagnostic testing, or some combination. There is no required waiting period before testing and diagnosis.
You cannot reproduce on your own or with a partner without medical intervention. This is the provision that reaches same-sex couples and single people who want biological children, since their situation inherently requires medical assistance.
You have been unable to establish or carry a pregnancy to live birth after 12 months of unprotected intercourse if you are under 35, or 6 months if you are 35 or older. A miscarriage does not reset the clock.

Before SB 729, California’s fertility coverage rules largely assumed a traditional conception scenario and excluded people who did not fit it. The new definition changes that.

What Plans Must Cover

Covered plans must pay for the diagnosis and treatment of infertility and for fertility services generally. The core IVF benefit is up to three completed oocyte retrievals with unlimited embryo transfers, following American Society for Reproductive Medicine guidelines.¹ Single embryo transfer is required when medically appropriate, a rule aimed at reducing the risks of multiple pregnancy.

Medically necessary fertility preservation is also covered, including egg or sperm freezing before cancer treatment or other procedures that could impair future fertility. Diagnostic workups are covered from the start, so you do not have to sit out the 6- or 12-month attempt period before your plan will pay for testing.

Fertility medications get a specific protection. Plans cannot impose restrictions on fertility drugs that differ from the ones they apply to other prescriptions.¹ If your plan offers 90-day mail-order supplies for other drugs, the same must be available for fertility medications, and fertility drugs must sit within the plan’s standard formulary tiers rather than being singled out.

What You Will Still Pay

The law does not make fertility care free. What it does require is parity: deductibles, copayments, coinsurance, benefit maximums, and waiting periods for infertility diagnosis and treatment cannot be different from those applied to other covered medical services.¹

A plan cannot set up a separate, higher deductible for fertility care or cap fertility benefits at a lower dollar figure than other care. Before SB 729, plans that nominally covered some infertility services often layered on separate lifetime maximums, higher coinsurance, or pharmacy carve-outs for fertility drugs. Those structures are prohibited under the new rule.

Donors, Surrogates, and Gestational Carriers

Plans cannot deny or exclude fertility coverage for the covered person just because a sperm donor, egg donor, embryo donor, gestational carrier, or surrogate is involved.¹ For same-sex couples and individuals who need donor gametes or a gestational carrier, that removes a common exclusion.

There is a limit to how far this reaches. The provision protects the enrollee’s own fertility treatment from being denied on account of third-party involvement. It does not clearly obligate plans to pay the third party’s medical costs, surrogate compensation, or donor coordination fees. Read your plan language carefully on those questions.

When the Coverage Starts

The mandate applies to contracts issued, amended, or renewed on or after January 1, 2026.¹ Because large-group employer contracts renew on annual cycles, an employer whose plan renews February 1, 2026, is subject to the mandate from that date, while a plan that renewed December 1, 2025, would not be covered until its next renewal in late 2026.

CalPERS runs on a separate track. Its health benefit contracts are not required to comply until July 1, 2027.

How To Check Your Own Plan

Three questions decide whether SB 729 applies to you. Is your employer’s plan fully insured or self-insured? Your HR department or plan administrator can answer that; self-insured plans are out regardless of employer size. Does your employer have 100 or more employees? And when does your plan renew, since the mandate takes effect at renewal on or after January 1, 2026.

If your plan qualifies, the insurer must include notice of the fertility benefit in the evidence of coverage. Request the current version and look for infertility and fertility services under covered benefits. If a plan that should be complying isn’t, you can file a complaint with the DMHC for health care service plans or the CDI for insurance policies; both agencies enforce California’s coverage mandates.
