CA SB 729: IVF Coverage, Plans Affected, and Cost-Sharing

California SB 729 IVF coverage takes effect for plans issued, amended, or renewed on or after January 1, 2026. The law requires fully insured large group health plans in California to cover in vitro fertilization and a broader set of fertility services, replacing the old rule that let insurers exclude IVF entirely. Whether it reaches your coverage depends almost entirely on what kind of plan you have.¹

Does SB 729 Apply to Your Plan

The statute draws sharp lines. Where your plan sits on those lines matters more than any other detail in the law.

Fully Insured Large Group Plans

If you work for an employer with 101 or more employees and your health plan is fully insured (the carrier bears the financial risk, not your employer), your plan must cover the fertility services described below. Coverage kicks in when the contract is issued, amended, or renewed on or after January 1, 2026.¹

Small Group Plans

For employers with 1 to 100 employees, carriers must offer a version of each plan that includes fertility coverage, but the employer decides whether to buy it. The mandate to purchase does not exist at this size.¹

Plans SB 729 Does Not Reach

Several categories fall outside the law entirely:

Self-funded employer plans. Many large California employers fund their own health benefits rather than buying insurance. These arrangements are governed by ERISA, which generally preempts state insurance mandates. Some self-funded employers voluntarily offer fertility benefits, but SB 729 does not require them to.²
Individual and ACA marketplace plans, including Covered California plans.
Religious employers, as defined in Health and Safety Code Section 1367.25 and Insurance Code Section 10123.196.³
Medi-Cal managed care contracts with the Department of Health Care Services.
Specialized policies: dental-only, vision-only, accident-only, and Medicare supplement plans.⁴

The self-funded exemption catches people off guard. From an employee’s view, a self-funded plan can look identical to a fully insured one, right down to the carrier logo on the ID card. Your HR department or the Summary Plan Description will tell you which category applies. If you cannot get IVF coverage under a large-employer plan after January 2026, self-funding is the first thing to check.

How the Law Defines Infertility

SB 729 lists three independent ways to qualify. You only need one:¹

A licensed physician’s clinical assessment based on your medical, sexual, and reproductive history, age, physical findings, or diagnostic testing.
Inability to reproduce as an individual or with a partner without medical intervention, regardless of the reason.
Failure to become pregnant after 12 months of unprotected intercourse, or 6 months if you are 35 or older. A pregnancy that ends in miscarriage does not restart the clock.

The middle criterion is the biggest change. Under the older framework, infertility was defined mainly through the time-based standard, which by its terms excluded single individuals and same-sex couples. Under SB 729, a single person or same-sex couple who needs medical help to conceive qualifies without waiting out a period that was never designed with them in mind.¹

Diagnostic testing and evaluation can also begin before the 12-month or 6-month window has closed. No need to wait out a full year before your doctor orders covered workup.

What Treatments Are Covered

Covered plans must pay for the diagnosis and treatment of infertility, from initial testing through advanced procedures.¹

IVF: Three Retrievals, Unlimited Transfers

IVF can no longer be excluded. Plans must cover up to three completed egg retrievals with unlimited embryo transfers. “Completed” is the operative word: a cycle canceled before retrieval should not count against the cap. Embryo transfers must follow ASRM guidelines, which generally call for transferring a single embryo when medically appropriate to reduce the risk of multiple pregnancies.¹

The unlimited-transfer piece matters in practice. A single retrieval can yield multiple viable embryos, and allowing unlimited transfers from those embryos lets a patient attempt pregnancy repeatedly without hitting a coverage wall.

Fertility Medications

Plans cannot impose restrictions on fertility medications that differ from restrictions on other prescription drugs. If your plan covers prescriptions with a standard copay and formulary, fertility drugs must be covered on the same terms, without higher copays, extra prior authorization, or formulary carve-outs that would not apply to comparable non-fertility prescriptions.¹

Other Services

Beyond IVF, covered services include diagnostic testing, ovulation induction, and intrauterine insemination (IUI), along with lab work and monitoring that goes with fertility treatment.

Fertility Preservation

Coverage extends to fertility preservation (freezing eggs, sperm, or embryos) when it is medically necessary. The core scenario is a patient facing treatment that carries a significant risk of causing permanent sterility, such as chemotherapy, radiation, or certain surgeries. If your doctor determines a planned treatment will likely damage your fertility, preserving your gametes beforehand must be covered.¹

Elective preservation, such as egg freezing for social or age-related reasons where no medical condition threatens fertility, is not required to be covered. Ongoing storage fees, which typically run from several hundred to over a thousand dollars a year, depend on your plan.

Surrogacy and Third-Party Reproduction

Plans cannot deny fertility coverage simply because a third party is involved. The statute defines third parties to include egg donors, sperm donors, embryo donors, gestational carriers, and surrogates. If you are the covered individual, your plan cannot refuse to pay for an embryo transfer, medications, or associated procedures because the embryo will be carried by a gestational carrier rather than you.¹

How costs get allocated when the gestational carrier has separate insurance is less clear. The statute stops your plan from denying your fertility benefits over third-party involvement, but medical care the carrier receives during pregnancy may fall under the carrier’s own coverage. If you are considering surrogacy, expect to work through those details with both your insurer and a reproductive law attorney.

Cost-Sharing Parity

SB 729 requires that fertility services carry the same financial terms as other medical care. Your plan cannot apply any deductible, copayment, coinsurance, benefit maximum, or waiting period to fertility services that differs from what it applies to non-fertility services.¹

In practice:

Fertility services count toward your plan’s regular deductible, not a separate one.
Fertility specialist copays match copays for other specialists.
Plans cannot set a lifetime dollar cap on fertility benefits that does not exist for other services.

The three-retrieval limit built into the statute is the only fertility-specific restriction the law permits. Everything else about how the plan collects money from you, and caps its own exposure, has to match what it does for the rest of your medical care.

What You Will Still Pay

Even with SB 729 in place, you will owe the plan’s standard deductible, copays, and coinsurance. Fertility treatment involves frequent monitoring visits, labs, and medications over several months, so those amounts accumulate. Health Savings Accounts and Flexible Spending Accounts let you pay qualifying costs with pre-tax dollars; the IRS treats fertility treatments as qualified medical expenses under Publication 502 when they diagnose or treat a medical condition. Your plan administrator may want a letter of medical necessity to confirm eligibility.

If your plan is one of the exempt categories and you are paying entirely out of pocket, the accounts matter more. A single IVF cycle without insurance runs roughly $10,500 to $24,000 before medications, and IUI procedures typically range from $1,200 to $7,500 per attempt.
