How to appeal a Humana neurosurgery — discectomy, laminectomy, craniotomy, shunt 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 neurosurgery — discectomy, laminectomy, craniotomy, shunt

Cited policy: Humana Medicare Advantage — defers to CMS NCD/LCD where applicable; case-by-case medical necessity for shunt revision and Chiari

Imaging-confirmed hydrocephalus (Evans index, callosal angle) + symptomatic decline OR shunt malfunction (obstructed catheter, infection, overdrainage); neurosurgical attestation.

How Humana denies neurosurgery — discectomy, laminectomy, craniotomy, shunt — and how to counter it

Where Humana pushes back: 1) Symptoms attributed to other cause; 2) Programmable shunt 'not medically necessary'; 3) Revision frequency questioned.

Counter-arguments that hold up: Imaging Evans index + callosal angle measurements. NPH triad (gait, cognition, urinary) documentation. Hydrocephalus Association consensus. Programmable shunt avoids repeat OR for pressure adjustment — outcome literature (Browd Neurosurgery 2006). Catheter blood-flow imaging if available.

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.
