Humana Behavioral Health Appeals in Massachusetts
Appealing a Humana behavioral health denial in Massachusetts means tracking two separate clocks: Humana's own 30-day Level-1 appeal window, and Massachusetts's 30-day prompt-payment statute (M.G.L. c.176G § 8) for clean-claim payment. This guide covers both, plus Humana's filing address and Massachusetts's parity protections.

Massachusetts's prompt-payment window
In Massachusetts, state-regulated (fully-insured) plans — including many Humana plans — generally must pay or formally respond to a clean claim within 30 calendar days under M.G.L. c.176G § 8. This deadline does not bind self-funded ERISA plans. This is a claim-payment deadline, not the appeal-decision deadline. If Humana missed this window on your claim, cite it as a separate payment violation alongside your Humana appeal — not as the deadline for the appeal decision itself.
30 days EFT / 45 days paper. MA Chapter 258 (An Act to Promote Access to Behavioral Health Services, 2024) adds additional parity mandates.
MHPAEA parity for Humana in Massachusetts
Massachusetts adds state-level parity protection
Massachusetts Chapter 176G requires mental health parity for fully insured plans. The 2024 Act to Promote Access to Behavioral Health Services (Ch. 258) added additional protections including enhanced external review rights, prior authorization reforms for mental health services, and network adequacy requirements. State enforcement by the Division of Insurance is independent of federal MHPAEA enforcement.
Statute: M.G.L. c.176G (verify current section); 2024 An Act to Promote Access to BH Services (confirm the current section before citing)
Humana's parity posture: Federal MHPAEA parity does not apply to Humana Medicare Advantage plans — the parity argument on this page applies only to Humana commercial/ERISA plans. Humana administers behavioral health through an internal BH team. Strong Medicare Advantage presence — MA plans follow Medicare appeals rules (42 CFR § 422), which differ from commercial ERISA rules.
When appealing a Humana denial in Massachusetts on a state-regulated, fully-insured plan, cite both federal MHPAEA (29 CFR § 2590.712) and M.G.L. c.176G (verify current section); 2024 An Act to Promote Access to BH Services (confirm the current section before citing) together — the state statute remains in force regardless of the 2025 federal non-enforcement of the 2024 MHPAEA Final Rule. Self-funded ERISA plans are preempted from state insurance law, so rely on federal MHPAEA alone there.
Common Humana denial codes
Massachusetts's insurance commissioner
If your internal Humana appeal is denied, Massachusetts's Department of Insurance can help with a complaint or external review for fully-insured plans. Look up the official contact via the NAIC consumer locator.
Note: self-funded ERISA plans are generally exempt from state insurance regulation. If your patient's Humana plan is employer-sponsored and self-funded, your remedies run through the U.S. Department of Labor (EBSA) rather than Massachusetts's commissioner.

How long does Humana have to respond to an appeal in Massachusetts?
Humana generally has 30 calendar days to respond to a Level-1 appeal. If denied, you have 60 days to request external review. Separately, Massachusetts's prompt-payment statute gives payers 30 days to respond to a clean claim (M.G.L. c.176G § 8) — a different deadline governing claim payment, not the appeal decision.
Does MHPAEA apply to Humana in Massachusetts?
Generally, yes — for Humana's group health plans. Federal MHPAEA applies to Humana's group health plans in Massachusetts. M.G.L. c.176G (verify current section); 2024 An Act to Promote Access to BH Services (confirm the current section before citing) additionally applies for state-regulated, fully-insured plans — self-funded ERISA plans are preempted from state insurance law and rely on federal MHPAEA alone; where it applies, Massachusetts's state law remains in force regardless of the 2025 federal non-enforcement announcement.
Where do I mail or fax a Humana appeal?
Mail to Humana Medical Appeals, P.O. Box 14601, Lexington, KY 40512. You can also fax to 1-800-832-4651. This address is the same nationally, including for Massachusetts providers.
