How to appeal a Humana substance use disorder treatment (sud/moud) denial

The framework that applies to your appeal

Medicare Advantage plans follow a separate appeal track from commercial plans. Reconsideration must be requested within 60 days; if the plan misses its deadline, the case auto-forwards to the IRE (Maximus).

Humana-specific note: Heavily Medicare Advantage focused. MA-specific appeal track (42 CFR Part 422 Subpart M) applies — 60 days to request reconsideration, NOT the 180 days for commercial plans. Auto-forward to IRE (Maximus) if Humana misses deadline.

What Humana's policy requires for substance use disorder treatment (sud/moud)

Cited policy: Humana Medical Coverage Policy — SUD Treatment + MA SUD benefit

MA must follow Traditional Medicare standards (CMS 2024 final rule).

How Humana denies substance use disorder treatment (sud/moud) — and how to counter it

Where Humana pushes back: 1) Residential SUD denied under MA — 'skilled nursing not required'; 2) Sublocade step therapy; 3) Inpatient detox (ASAM 4) denied as 'ambulatory WM appropriate'.

Counter-arguments that hold up: CMS 2024 MA final rule — MA plans must follow Traditional Medicare coverage standards and cannot impose more restrictive criteria; SUD residential covered when medically necessary. CIWA/COWS objective scores documenting severity for ASAM 3.7-WM / 4. Mortality risk (alcohol/sedative WM seizure risk; opioid WM with cardiac/pregnancy comorbidity).

How to submit the appeal to Humana

1. Read the denial letter — note the exact denial reason code and the appeal deadline (60 days from the date on the letter).
2. Gather supporting documentation: physician letter of medical necessity, relevant clinical notes, peer-reviewed citations supporting the treatment for your indication, and the policy or coverage document Humana cited in the denial.
3. File the appeal through Humana's portal (members: https://www.humana.com ; providers: https://www.humana.com/provider). Standard decision returns within 30 days; expedited urgent appeals return within 72 hours.
4. If denied again, request external review by an independent reviewer within 4 months of the final internal denial. In KY, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
