Having your Fertility Treatment and In Vitro Fertilization (IVF) denied by insurance is frustrating, but you have legal rights and a strong path to overturn the denial. Approximately 40-60% of insurance denials are overturned on appeal when patients submit comprehensive documentation and cite applicable laws. This guide walks you through exactly why fertility treatment / ivf claims get denied, what medical necessity criteria major insurers apply, and how to build the strongest possible appeal.

Why Fertility Treatment / IVF Gets Denied by Insurance
Fertility Treatment / IVF denials typically fall into specific, predictable patterns. Understanding the exact reason for your denial is the first step to building an effective appeal. The most common denial reasons for Fertility Treatment and In Vitro Fertilization (IVF) include:
- Reason 1: State does not mandate fertility coverage, and the plan excludes infertility treatment
- Reason 2: Patient has not completed the required infertility workup or qualifying period of documented infertility
- Reason 3: The specific treatment (IVF, ICSI, PGT) is excluded under the plan or considered not medically necessary
- Reason 4: Age-based exclusion — some plans limit IVF coverage based on patient age
- Reason 5: The number of IVF cycles requested exceeds the plan's lifetime maximum
Your Explanation of Benefits (EOB) or denial letter should include a specific reason code. Match that code to the reasons above to target your appeal effectively. If the denial letter is vague, you have the legal right to request the specific clinical criteria used to evaluate your claim.
Common Denial Codes for Fertility Treatment / IVF
Insurance companies use standardized codes to explain denials. Here are the codes most frequently associated with fertility treatment / ivf denials:
| Denial Code | What It Means |
|---|---|
| CO-96 | Non-covered charge — excluded benefit |
| CO-50 | Not medically necessary |
| CO-119 | Benefit maximum reached |
| CO-167 | Diagnosis not covered |
Understanding your specific denial code helps you tailor your appeal to address the exact basis for denial rather than making generic arguments. Request your complete claims file if the denial codes are not clear from your EOB. Use our EOB Decoder tool to understand your denial documentation.
Medical Necessity Criteria for Fertility Treatment / IVF
Fertility coverage varies dramatically by state and plan. Twenty-one states have fertility insurance laws, but coverage depth varies. States with IVF mandates include Connecticut, Illinois, Maryland, Massachusetts, New Jersey, and Rhode Island among others. Insurers in mandate states typically require documentation of 12 months of infertility (6 months for women over 35), completed diagnostic workup (hormone levels, HSG, semen analysis), and trial of less invasive treatments (ovulation induction, IUI) before IVF approval. Some plans cap IVF at 2-4 lifetime cycles. Self-insured employer plans (ERISA plans) are generally exempt from state mandates.
Key Takeaway
Each insurer applies different medical necessity criteria for fertility treatment / ivf. Request your specific insurer's medical policy for this procedure. The criteria they use must be disclosed to you upon request, and your appeal should address each criterion point by point.
Step-by-Step Appeal Process for Fertility Treatment / IVF
Step 1: Request the Complete Written Denial
Contact your insurer and request the full written denial including the specific clinical criteria used, the reviewer's credentials, and your appeal rights and deadlines. Under ACA Section 2719, you are entitled to this information. Keep a log of every communication with your insurer — dates, names, reference numbers.
Step 2: Obtain Your Complete Medical Records
Request all records relevant to your fertility treatment / ivf claim from every provider involved. Under HIPAA, you are entitled to your complete medical records. Focus on documentation that directly addresses the denial reason.
Step 3: Get a Letter of Medical Necessity from Your Provider
Ask your treating physician to write a detailed letter explaining exactly why Fertility Treatment and In Vitro Fertilization (IVF) is medically necessary for your specific condition. The letter should reference the insurer's specific medical policy criteria and address each requirement. A generic letter is far less effective than one that directly responds to the denial reason.
Step 4: Gather Supporting Clinical Evidence
Collect clinical practice guidelines from relevant medical societies, peer-reviewed research supporting the procedure for your diagnosis, and any applicable insurer-specific policy bulletins. Evidence from the same clinical guidelines the insurer references is particularly powerful.
Step 5: Write and Submit Your Appeal
Your appeal should cite specific laws (ACA Section 2719, ERISA Section 503 if applicable, and relevant state laws), address the exact denial reason with point-by-point rebuttal, include all supporting documentation, and request a specific outcome (approval of the denied service). Submit by certified mail or through the insurer's online portal with delivery confirmation.
Step 6: If Denied, Escalate to External Review
If your internal appeal is denied, you have the right to an external review by an Independent Review Organization (IRO) under the ACA. The external reviewer is independent of the insurer and makes a binding determination. External review must be requested within 4 months of the internal appeal denial in most states. For urgent situations, expedited external review must be decided within 72 hours.
Sample Appeal Letter Language for Fertility Treatment / IVF
Sample Appeal Excerpt
I appeal the denial of in vitro fertilization, claim [X]. The patient has documented infertility of [X months/years] duration, with the following completed diagnostic workup: [list completed evaluations]. Less invasive treatments have been attempted: [list IUI cycles, ovulation induction]. These treatments were unsuccessful as documented in the attached records. Under [state] Insurance Code Section [X], which mandates coverage of infertility treatment including IVF, the denial of this medically necessary treatment is inconsistent with state law requirements. The treating reproductive endocrinologist's letter, attached, confirms IVF is the appropriate next step given [specific clinical factors].
Customize this language with your specific details — claim numbers, dates, provider names, and clinical findings. A personalized appeal that addresses the specific denial reason is significantly more effective than a generic template. Use our free appeal letter generator to build a complete letter.
Supporting Documentation to Strengthen Your Appeal
For fertility treatment / ivf appeals, gather the following documentation before submitting:
- Documentation of infertility duration (12 months or 6 months if age 35+)
- Complete diagnostic workup results (hormones, imaging, semen analysis)
- Records of prior less-invasive treatment attempts (IUI, ovulation induction)
- Reproductive endocrinologist's letter of medical necessity
- Relevant state mandate documentation if applicable
- Employer plan documents (SPD) for ERISA plan benefit verification
Organize your documentation clearly with a cover page listing all enclosed items. Number each exhibit and reference them specifically in your appeal letter. Incomplete or disorganized submissions are easier for insurers to deny.
Success Rate and Tips for Fertility Treatment / IVF Appeals
While specific success rates vary by insurer and clinical scenario, data from state insurance regulators suggests that 40-60% of medical necessity denials are overturned when patients pursue a comprehensive appeal. For fertility treatment / ivf specifically, the following strategies may improve your chances:
- Determine whether your state mandates IVF coverage and whether your plan is subject to the mandate
- Self-insured (ERISA) plans are exempt from state mandates — check your plan type in the SPD
- Document every failed treatment attempt — insurers require progressive treatment before IVF
- If age exclusions apply, cite recent ASRM guidelines on appropriate age ranges for treatment
The single most important factor in appeal success is the quality and specificity of your documentation. Generic appeals fail. Appeals that address the exact denial reason with targeted clinical evidence succeed at much higher rates.
Check your appeal deadline to ensure you file within the required timeframe. Missing the deadline may forfeit your appeal rights entirely.
Frequently Asked Questions
Which states require insurance to cover IVF?
As of 2026, states with IVF coverage mandates include Arkansas, Colorado, Connecticut, Delaware, Illinois, Louisiana, Maine, Maryland, Massachusetts, Montana, New Hampshire, New Jersey, New York, Ohio, Rhode Island, and Utah, though the specific requirements vary significantly by state. Some states mandate that insurers offer IVF coverage, while others mandate that insurers cover it. Self-insured employer plans are generally exempt from state mandates under ERISA preemption.
What if my employer's plan is self-insured and excludes IVF?
Self-insured plans are governed by ERISA and are exempt from state insurance mandates. If your self-insured plan excludes IVF, a mandate-based appeal will not succeed. However, you may still appeal on medical necessity grounds if the plan covers diagnostic infertility services or if the infertility is secondary to a covered medical condition (endometriosis, PCOS). Some employees have also successfully advocated for their employers to voluntarily add fertility benefits.
How many IVF cycles does insurance typically cover?
Coverage limits vary by plan and state mandate. Massachusetts mandates coverage with no specific cycle limit as long as treatment is medically appropriate. Illinois mandates coverage for up to 4 egg retrievals. Other states cap at 2-3 cycles. Many employer plans that voluntarily offer IVF coverage set a lifetime dollar maximum (commonly $15,000-$50,000) rather than a cycle limit. Check your plan's Summary Plan Description for specific limits.
Can I appeal an age-based IVF denial?
Some insurers deny IVF for patients over a certain age (often 42-45) based on diminished clinical success rates. Appeal by providing your reproductive endocrinologist's assessment of your specific fertility potential (ovarian reserve testing, AMH levels, antral follicle count), citing ASRM guidelines that do not set a strict age cutoff, and arguing that individualized assessment rather than blanket age exclusions is medically appropriate. Some state mandates prohibit age-based denials.
Does insurance cover egg freezing?
Elective egg freezing (oocyte cryopreservation) for fertility preservation is increasingly covered, particularly when medically indicated — before cancer treatment, for transgender patients before hormone therapy, or for conditions that threaten future fertility. Elective social egg freezing (without medical indication) is less commonly covered but is becoming an employer benefit at some companies. Check your plan documents and state laws for specific coverage details.
