Egg Freezing / Fertility Preservation Insurance Denied? How to Appeal

Egg freezing (oocyte cryopreservation) and fertility preservation are denied by insurance for two very different reasons — and your appeal strategy depends critically on which situation applies to you. For patients undergoing chemotherapy, radiation, or other treatments that threaten fertility, egg freezing is medically necessary and increasingly covered under state mandates. For elective social egg freezing, coverage is rarer but state mandates are expanding. This guide explains both paths.

Why Egg Freezing Gets Denied

Classified as elective, not medically necessary. The most common denial for non-oncology patients. The insurer treats egg freezing as an elective fertility service, not a medical necessity. However, for patients whose fertility is threatened by a medical treatment, the calculus is different — and many state infertility mandates now explicitly cover fertility preservation.

State infertility mandate does not apply. Not all states with infertility coverage mandates include egg freezing. Some mandates cover IVF but not egg freezing specifically. Others exclude elective fertility preservation. Know your state's specific mandate language.

Diagnosis code mismatch. For medically necessary fertility preservation (oncofertility), the diagnosis must document the underlying condition threatening fertility (e.g., malignant neoplasm requiring gonadotoxic chemotherapy). If the claim is coded as infertility only — without the underlying medical diagnosis — it may be denied.

Plan exclusion for "fertility treatment." Some plans broadly exclude all fertility treatments. However, fertility preservation for a patient whose fertility is threatened by a covered medical treatment (cancer, lupus, endometriosis requiring surgery) may be distinguishable from "elective infertility treatment" under the plan terms.

Employer self-funded plan exemption. Self-funded employer plans are not required to follow state infertility mandates. If your employer self-funds its health plan, state mandates may not apply and coverage depends entirely on the plan document.

Medical Necessity vs. Elective: A Critical Distinction

Medically necessary fertility preservation (oncofertility) occurs when a patient is diagnosed with a condition requiring treatment that is gonadotoxic (damages eggs or ovaries). Common triggers:

• Cancer requiring chemotherapy (alkylating agents are particularly gonadotoxic) or pelvic radiation
• Autoimmune diseases requiring cyclophosphamide or other gonadotoxic agents
• Turner syndrome and other conditions causing premature ovarian insufficiency
• Endometriosis requiring bilateral oophorectomy

For these patients, egg freezing is not elective — it is the only opportunity to preserve the option of biological parenthood before gonadotoxic treatment destroys that option. The American Society of Clinical Oncology (ASCO) and the American Society for Reproductive Medicine (ASRM) both recommend offering fertility preservation counseling and, where possible, preservation procedures before gonadotoxic treatment begins.

Elective social egg freezing — freezing eggs for non-medical reasons in order to delay childbearing — is treated differently. Coverage depends on whether the plan includes elective fertility preservation benefits. An increasing number of large employers offer this benefit, and several states now mandate it.

State Mandates for Fertility Preservation

As of 2026, over 20 states have enacted fertility insurance mandates. States with explicit fertility preservation mandates for medically necessary cases include:

• California (AB 2764, 2019): Requires coverage for fertility preservation when fertility may be threatened by a covered medical treatment
• New York: Covers fertility preservation for patients facing iatrogenic infertility
• Illinois, Connecticut, Maryland, New Jersey, Rhode Island, Delaware, Massachusetts, Montana, Texas, Utah, and others: Have varying degrees of infertility and fertility preservation coverage requirements

Check your state's specific mandate. The National Infertility Association (RESOLVE) maintains a state-by-state mandate database at resolve.org.

Your Legal Rights

ACA essential health benefits. The ACA's EHB requirements do not mandate fertility treatment coverage, but plans cannot impose annual or lifetime dollar limits on EHBs, and some fertility-adjacent services may fall within covered categories.

State infertility mandates. Apply to fully insured plans only. Self-funded ERISA plans are not required to comply. Know whether your plan is fully insured or self-funded before citing state mandates in your appeal.

ACA non-discrimination (Section 1557). Denying fertility preservation coverage to patients with cancer while covering the cancer treatment may raise non-discrimination questions in some circumstances.

ERISA. For employer-sponsored plans, ERISA guarantees full and fair review of any adverse benefit determination. Even if state mandates do not apply, you can appeal under ERISA and argue for coverage based on plan language and medical necessity.

Step-by-Step Appeal

Step 1: Identify whether your case is medically necessary or elective. If you have a diagnosis threatening your fertility (cancer, autoimmune disease, genetic condition), your appeal centers on medical necessity and applicable state mandates for oncofertility. If elective, your appeal must rely on plan document language, employer benefit descriptions, or state mandates that include elective preservation.

Step 2: Obtain documentation from your physician. For medically necessary cases, your oncologist or specialist should document:

• The underlying diagnosis and the specific treatment required
• That the treatment is gonadotoxic and will likely result in permanent fertility loss
• That egg freezing is the medically indicated fertility preservation intervention
• That ASCO/ASRM guidelines recommend fertility preservation before gonadotoxic treatment

Step 3: Cite applicable state mandate. If your state has a fertility preservation mandate, quote the specific statutory language and explain how your situation falls within its scope.

Step 4: Challenge plan exclusion language. If the plan excludes "fertility treatment," argue that fertility preservation for a patient undergoing treatment for a covered medical condition is not "fertility treatment" as commonly understood — it is a component of comprehensive cancer or disease management.
