How to appeal an IVF insurance denial in Tennessee
Tennessee has no law requiring insurers to cover IVF or infertility treatment. A 2025 law (the Fertility Treatment and Contraceptive Protection Act) protects the legal right to receive fertility treatment in Tennessee but explicitly does not create any insurance coverage requirement.
How to appeal a denial
- 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.
- 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.
- Regulator — Tennessee Department of Commerce and Insurance. Tennessee external review of adverse determinations (Tenn. Code Ann. § 56-61-109) 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.
