Your legal rights

The federal and state rules that govern health-insurance appeals — ACA, ERISA, Mental Health Parity, No Surprises Act.

IVF and fertility denial appeals — what your state allows

How state IVF mandates (NJ, NY, IL, MA, RI, CT, CO and others) interact with ERISA preemption for self-funded plans, plus the clinical evidence that wins fertility appeals.

Mental health therapy denied — using the Parity Act

Identifying parity violations (session caps, prior-auth disparity, NQTLs, network adequacy) in therapy denials and invoking MHPAEA plus the 2024 final-rule comparative-analysis requirement.

Mental Health Parity Act: using it in your appeal

MHPAEA and the 2020 CAA require parity; this guide shows how to identify a parity violation in a denial (session caps, MH-only prior-auth, narrower medical-necessity rules, network gaps) and how to frame it in an internal appeal or state DOI / DOL complaint.

ERISA appeals: when federal law governs your plan

ERISA governs most employer health plans: 29 CFR 2560.503-1 timelines, 'full and fair review,' self-funded vs fully-insured distinction, HHS federal external review path, and the practical implications for the appeal letter.

No Surprises Act: what it covers and what it doesn't

Federal protections for emergency services, OON ancillary at in-network facilities, and air ambulance; the IDR back-end; notice-and-consent waiver risks; ground-ambulance gap; how to invoke the Act in an OON appeal.

ACA appeal rights — the federal floor

The 45 CFR 147.136 floor — 180 days to file, 30/60/72-hour decision windows, full and fair review, binding external review — and which plans (grandfathered, short-term, fixed-indemnity) it does not reach.

Can I sue my insurance company for denying my claim?

Honest framing: the administrative ladder (internal → external → DOI/DOL → court), ERISA preemption, bad-faith law's narrowness, and when retaining counsel actually makes sense ($$, ongoing care, pattern denials).
