10 Pitfalls Every Patient Needs to Know — And How to Fight for the Coverage You Deserve

When California Governor Gavin Newsom signed Senate Bill 729 into law in September 2024, the headlines were celebratory — and rightfully so. For the first time in California history, IVF and infertility treatment would be mandated coverage under certain health insurance plans. LGBTQ+ individuals, single parents by choice, and thousands of Californians who had been shut out of fertility care finally had a path forward.

While this article focuses on California’s SB 729, the questions, pitfalls, and advocacy strategies outlined here are a roadmap for anyone — in any state — fighting for fertility coverage. If you are navigating insurance denials, employer benefit gaps, or legislative mandates wherever you live, the tools in this guide apply to you.

But here at INCIID, we’ve been serving the infertility community for three decades. And we’ve learned something important: the gap between what a law promises and what a patient actually receives can be enormous. SB 729 is landmark legislation. It is also deeply misunderstood — and that misunderstanding costs patients money, time, and heartbreak.

This article identifies 10 specific pitfalls that stand between California fertility patients and the coverage they believe they have. We cover what the law says, what it actually means in practice, what should have been written into it but wasn’t, and exactly how to fight for every dollar of coverage you are entitled to.

This article covers four sections:

• Part One: The two headline pitfalls — Pitfalls #1 and #2
• Part Two: Eight additional pitfalls patients need to know — Pitfalls #3 through #9
• Part Three: What should be in the law but isn’t — Pitfall #10, the religious exemption problem
• Part Four: How to fight for the coverage you deserve — a step-by-step patient advocacy guide

Part One: The Two Headline Pitfalls

If you remember nothing else from this article, remember these two pitfalls. They determine everything about whether SB 729 applies to you at all.

PITFALL #1: Fully Insured vs. Self-Funded — The ERISA Loophole That Nobody Talks About

This is the single most important thing to understand about SB 729, and it is almost never explained clearly in news coverage. Millions of California workers who believe they are covered under this law are not — and they will not find out until they get the bill.

What “Fully Insured” Means

When your employer purchases health insurance from an insurance company — Anthem, Blue Shield, United Healthcare, Aetna — and that insurance company takes on the financial risk of paying your medical claims, your plan is “fully insured.” State laws like SB 729 can regulate insurance companies, which is why fully insured plans must comply with the mandate.

What “Self-Funded” Means

Many employers — especially large companies — do not purchase insurance at all. Instead, they act as their own insurance company. They collect premiums from employees, hold that money, and pay medical claims directly from company funds. They often hire a third party like Aetna or United Healthcare just to process the paperwork. Your insurance card might say “Aetna” in large letters — but Aetna is just an administrator. Your employer is actually paying your bills.

Why This Is Pitfall #1

State laws can regulate insurance companies. When your employer self-funds, they are not an insurance company — they are governed by federal ERISA law, which does not require fertility coverage. This means that even if you work for a 50,000-person company headquartered in California, if they self-fund their health plan, SB 729 does not apply to you. Not one cent of mandatory IVF coverage. Zero!

This is not a loophole. It is a fundamental feature of how federal and state law interact, and it affects an enormous number of California workers. Self-funded plans are extremely common among employers in large companies precisely because self-funding gives companies more control over their benefits costs and what is covered.

WHAT PATIENTS SHOULD KNOW: Do not guess whether your plan is fully insured or self-funded. Do not assume. Many patients at major corporations will discover SB 729 does not protect them at all. In Part Four we show you exactly how to find out — including how to research the answer before you even walk into HR.

PITFALL #2: “Required to Offer” vs. “Required to Provide” — The Small Employer Opt-Out

Even among employers whose plans are subject to SB 729, not all coverage is equal. The law draws a critical distinction based on employer size that most patients don’t know exists — and it is written in language so technical that even HR professionals may misread.

Large Group Employers — 101 or More Employees

These employers with fully insured plans are required to provide coverage. It must be included. You don’t have to ask for it, opt in, or pay extra. It is part of your plan by law.

Small Group Employers — 100 or Fewer Employees

Here is where the language of the law becomes critically important — and deeply misleading. SB 729 requires small group insurance carriers to offer the infertility coverage option to small employers. But it does not require small employers to actually purchase that coverage for their employees.

The Analogy That Explains It

Think of it like a lifeguard required to hang a life preserver on the pool fence. The law is satisfied the moment it’s hanging there. Nobody is required to throw it to you if you’re drowning.

In plain English: your small employer’s insurance company has to make fertility coverage available as an add-on option. But your employer can look at that option and say “no thank you” — and there is nothing in SB 729 that forces them to say yes. Nobody is required to tell you they said no. You will find out when you get the bill.

Is This What the Law Intended?

No. The offer-vs-provide carve-out exists because of cost concerns and lobbying pressure from small business advocacy groups during the legislative process. The compromise was the offer language. Small employers got an out. Insurance companies got to say they comply. And patients got a false sense of security.

A mandate that requires carriers to offer coverage without requiring employers to purchase it places the entire burden of advocacy on the patient. The patient has to know to ask. The patient has to know what questions to ask. The patient has to know they have the right to appeal a denial. Most patients don’t know any of this. They read the headline, believe they have coverage, and find out the truth when they get a bill they cannot pay.

WHAT PATIENTS SHOULD KNOW: If you work for a small employer, call HR today and ask directly: “Did we opt into infertility coverage this year?” Do not assume the answer is yes. Get the answer in writing.

Part Two: Eight More Pitfalls Patients Need to Know

Beyond the two headline issues, SB 729 contains six more gaps and ambiguities that can blindside patients who don’t know to look for them. Each one is a real pitfall with real financial consequences.

PITFALL #3: Your Coverage Doesn’t Start January 1, 2026 — It Starts at Renewal

SB 729 took effect January 1, 2026, but that doesn’t mean your coverage started that day. Coverage begins when your employer’s insurance contract renews on or after that date. Many plans renew in January, but some renew mid-year. If your plan renews in July, you may not have SB 729 coverage until July 2026 or later.

⚠ WHAT PATIENTS SHOULD KNOW: Ask HR when your plan renews. Do not begin treatment assuming coverage is already in place until you have confirmed your plan has renewed under the new mandate.

PITFALL #4: State Employees Are Left Behind Until 2027

If you are a California state employee covered under CalPERS — the California Public Employees’ Retirement System — SB 729 does not apply to your plan until July 1, 2027. That is a full year and a half after the law took effect for most other Californians. The implementation delay for state employees was written into the law and is not subject to change without further legislation.

WHAT PATIENTS SHOULD KNOW: If you work for the State of California and are planning fertility treatment, do not assume you have SB 729 coverage. You do not — not until July 2027.

PITFALL #5: The Three Retrieval Limit Is Per Lifetime — Not Per Year

SB 729 mandates coverage for up to three completed egg retrievals and unlimited embryo transfers. What many patients don’t realize is that this is a lifetime limit per infertility diagnosis — not an annual benefit that resets each year. If you use all three retrievals and still haven’t achieved a live birth, you have exhausted your covered benefit under the law.

This has significant implications for how you and your physician plan your treatment protocol. Some physicians prefer to do multiple retrievals before any transfers in order to bank embryos. Others recommend transferring after each retrieval. The law does not specify which approach must be followed, but your insurer may. Clarify this with both your physician and your insurer before your first retrieval.

WHAT PATIENTS SHOULD KNOW: Three retrievals may sound like a lot. For patients with diminished ovarian reserve, poor response, or repeated implantation failure, three cycles can be exhausted faster than expected. Understand this limit before you begin, and plan your protocol strategically with your physician.

PITFALL #6: Prior Authorization Is Still Required — And First-Year Denials Will Be High

The mandate does not eliminate prior authorization. Insurers can still require you to obtain approval before beginning treatment. Given that this is the first year of implementation, denial rates on newly covered patients are expected to be higher than normal as insurance companies work through their internal guidelines and documentation requirements.

A first denial is not a final answer. It is frequently a documentation problem, not a coverage decision. In many cases, a letter of medical necessity from your physician, combined with a timely appeal, will reverse a denial.

WHAT PATIENTS SHOULD KNOW: Do not begin any fertility treatment before obtaining written prior authorization from your insurer. A denial after the fact is nearly impossible to reverse. Document every interaction with your insurer’s prior authorization team. And get the authorization in writing!

PITFALL #7: Embryo Storage and Donor Gametes — The Coverage Nobody Can Define Yet

One of the most significant unresolved issues in SB 729 is what happens with embryo storage costs and donor gametes — donor eggs, donor sperm, and donor embryos. The law prohibits plans from denying coverage based on participation in third-party fertility services, but what exactly must be covered in those arrangements remains unclear.

California’s Department of Insurance and the Department of Managed Health Care have not yet issued specific guidance on these areas. This means coverage varies significantly by insurer. Patients using donor material, gestational carriers, or surrogates may face unexpected out-of-pocket costs that they assumed were covered.

WHAT PATIENTS SHOULD KNOW: Before beginning any treatment involving donor gametes, embryo storage, or a gestational carrier, call your insurer and ask specifically what is covered and what is not. Get the answer in writing. Do not assume the mandate covers these costs — it may not.

PITFALL #8: Elective Egg Freezing Is Not Covered

SB 729 covers medically necessary fertility preservation — for example, egg or embryo freezing before cancer treatment or other medically necessary procedures that would compromise fertility. It does not cover elective egg freezing for social reasons, such as delaying parenthood for personal or professional choices.

If you want to freeze your eggs because you are not ready to have children but want to preserve the option for the future, you will still be paying out of pocket. This is one of the most common misunderstandings about the mandate.

WHAT PATIENTS SHOULD KNOW: If your physician has not given you a medical reason for fertility preservation, your egg freezing will not be covered under SB 729. Ask your physician whether your situation qualifies as medically necessary preservation before assuming coverage.

PITFALL #9: The Religious Employer Exemption — Broader Than Anyone Is Saying

SB 729 includes a religious employer exemption. On the surface, this sounds straightforward — churches, dioceses, religious schools. In practice, it is one of the most legally and ethically complex fault lines in reproductive healthcare law — and it has the potential to affect far more patients than most people realize.

The exemption as written covers employers whose primary purpose is religious ministry and who primarily employ and serve people who share their religious tenets. That sounds like a narrow definition. But we live in a post-Hobby Lobby world.

In 2014, the U.S. Supreme Court ruled in Burwell v. Hobby Lobby that closely held for-profit corporations could claim religious exemptions from federal health coverage mandates. The owners of a craft store chain argued that certain contraceptives violated their sincerely held religious beliefs. The Court agreed.

Now apply that logic to SB 729 and IVF. IVF typically creates more embryos than are transferred. Unused embryos may be frozen, donated, or discarded. For employers — or business owners — who believe that life begins at fertilization, the creation and potential destruction of embryos is morally equivalent to abortion. This is the official teaching of the Catholic Church and the stated belief of many business owners.

SB 729’s religious exemption was written with traditional religious organizations in mind. It did not anticipate — or explicitly address — a Hobby Lobby-style challenge from a for-profit employer whose owners hold sincere religious objections to IVF specifically. That case has not yet been filed in California. But it will be.

WHAT PATIENTS SHOULD KNOW: If you work for a religiously affiliated organization — a hospital, school, charity, or any employer with religious ownership — do not assume SB 729 protects you. Ask HR explicitly whether your plan covers IVF. The answer may surprise you.

Part Three: What Should Be in the Law But Isn’t

PITFALL #10: The Structural Failures of SB 729 — What the Legislature Should Have Written

The ten pitfalls in this article are not accidents. They are the predictable consequences of a law that made political compromises at the expense of patient protection. Here is what should have been written into SB 729 — and what advocates must push for going forward.

The Small Employer Gap Must Be Closed

The offer-vs-provide distinction for small employers should be eliminated. Small group employers should be required to provide infertility coverage, not merely be offered it — with a reasonable phase-in period to manage cost impact. Several other states with strong fertility mandates have done exactly this. Until California closes this gap, hundreds of thousands of workers at small employers will remain unprotected regardless of what the headlines say.

The ERISA Problem Requires Federal Action

No state law can fix the ERISA self-funded exemption. Only Congress can. A federal fertility coverage standard that eliminates the ERISA loophole is the next frontier for patient advocacy. Organizations like INCIID and RESOLVE are actively working toward this goal. Contact your federal representatives and tell them that fertility coverage should not depend on how your employer chooses to structure its health plan.

The Religious Exemption Must Be Narrowed

SB 729’s religious exemption should be limited to organizations whose primary purpose is religious ministry — churches, synagogues, mosques, and religious schools operated by religious organizations. It should not extend to:

• For-profit businesses owned by religious individuals
• Religiously affiliated hospitals and health systems that serve the general public and employ people of all faiths
• Any employer that receives public funding or public contracts

The law should also include an explicit provision that an employer’s religious exemption cannot override a physician’s determination that fertility treatment is medically necessary for a specific patient. An employer’s theology should not determine a patient’s access to medically necessary care.

Whose Religious Beliefs Govern Whose Medical Care?

When a religious employer claims exemption from IVF coverage, they are making a theological determination about when life begins and imposing that determination on every employee who works for them, regardless of the employee’s own beliefs. A Jewish employee, for example, works under a religious framework in which IVF is not only permitted but often encouraged. Her employer’s beliefs about embryos have now effectively overridden her own religious and medical autonomy. This is the Hobby Lobby problem applied to fertility — and it is one of the most important unresolved questions in the law.

SB 729 is progress — real progress — but progress that leaves millions of people behind isn’t finished work. The job of patient advocacy is to say that out loud, clearly, and without apology. Download SB729_INCIID_Complete_guide_to_mandate
