How to appeal a Humana neurology — alzheimer's, parkinson's, als, epilepsy 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 neurology — alzheimer's, parkinson's, als, epilepsy

Cited policy: Humana Medicare Advantage — follows CMS NCD 200.3 (anti-amyloid CED)

CMS NCD 200.3 mandates: registry (CED) enrollment + amyloid+ confirmation + MRI baseline + prescriber criteria.

How Humana denies neurology — alzheimer's, parkinson's, als, epilepsy — and how to counter it

Where Humana pushes back: 1) Registry not confirmed at claim time; 2) ICD-10 specificity (G30.9 vs G30.0/G30.1); 3) HCPCS J0174/J0175 modifier issues.

Counter-arguments that hold up: Include CMS registry enrollment ID. Precise ICD-10 (G30.0 early-onset AD, G30.1 late-onset, G31.84 MCI). Cite NCD 200.3 verbatim. Medicare appeal levels: redetermination → reconsideration → ALJ.

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.
