How to appeal an IVF insurance denial in Wisconsin

Wisconsin has no law requiring insurers, Medicaid (ForwardHealth), or the state employee (ETF) health plan to cover infertility diagnosis, treatment, or IVF. A 2026 bill (the Building Families Act, AB 1110/SB 566) would create a broad mandate but is still sitting in its first committee.

How to appeal a denial

1. Internal appeal — you have 180 days from the denial to file. The plan must decide within 30 days (before service) or 60 days (after service); 72 hours if urgent.
2. External review — available for at least 4 months after the final internal denial, for medical-necessity and "experimental" denials (PGT-A, ICSI, step therapy). An independent reviewer decides within 45 days. Contractual exclusions are not eligible for external review — those go to the regulator as a complaint.
3. Regulator — Wisconsin Office of the Commissioner of Insurance. Wisconsin independent review of grievances (Wis. Stat. § 632.835; Wis. Admin. Code Ins 18) File a complaint. Copy the regulator on every appeal letter; clinics report it speeds things up.

If your plan is self-funded, skip the state regulator: your appeal runs under ERISA and complaints go to the U.S. Department of Labor's Employee Benefits Security Administration.

Common denial reasons and what to argue

• Step therapy / prior-treatment requirements — check your plan's own Summary Plan Description or clinical policy for its step-therapy criteria and ask the payer for its bypass criteria (age 38+, tubal factor, stage III–IV endometriosis, severe male factor are common).
• Benefit limits — if your employer voluntarily covers fertility care, the denial is governed entirely by the plan document, not state law; ask for the exact clause the denial relied on.
• 'Experimental' (PGT-A, ERA, ICSI without male factor) — eligible for external review; ask the clinic for a medical-necessity letter. Success is limited for PGT-A.
• Medication routing — many denials are the wrong pharmacy or a missing prior auth, not a coverage decision. Ask the specialty pharmacy to re-run with prior auth.
• AI-only review — several states now bar insurers from denying on medical necessity without a physician's individualized review; ask in writing whether AI was the sole basis.

Where people get surprised

• Nothing is required of any Wisconsin plan today — fully insured, self-funded, or individual-market.
• Wisconsin Medicaid (ForwardHealth/BadgerCare Plus) lists infertility testing, artificial insemination, and surrogacy-related services as noncovered under its family-planning benefit — infertility diagnosis and treatment are excluded outright, not just IVF.
• AB 1110 / SB 566 (2025-26 session, 'Building Families Act'), introduced 2026-03-13 by Sen. Roys and Rep. Emerson, would require broader health insurance coverage of fertility treatment and direct the Dept. of Health Services to seek a federal Medicaid waiver or state plan amendment for fertility-treatment reimbursement — it was referred to committee and had not had a hearing as of this writing.
• The state employee (ETF Group Health Insurance) plan has no published infertility or IVF benefit in its general plan documents.

What may change

• WI AB 1110 / SB 566 (2025-26, 'Building Families Act') — Would create statutory fertility-treatment rights, require health insurance policies and plans to cover infertility services and fertility preservation, and direct the Department of Health Services to request any necessary federal Medicaid waiver or state plan amendment to allow Medical Assistance reimbursement for fertility treatment. Status: Introduced 2026-03-13 (AB 1110 by Rep. Emerson et al.; SB 566 by Sen. Roys et al., with Sens. Ratcliff, Hesselbein, Spreitzer, and Larson as co-sponsors); referred to committee (Assembly Committee on Health, Aging and Long-Term Care for AB 1110); no committee vote recorded as of 2026-09-06..
