How to appeal a Humana diabetes drugs & insulin denial
42 CFR Part 422 Subpart M (Medicare Advantage) · 60-day window · 30-day decision
To appeal a Humana diabetes drugs & insulin denial, file an internal appeal within 60 days of the date on the denial letter through Humana's member or provider portal, under 42 CFR Part 422 Subpart M (Medicare Advantage). Humana returns standard decisions in 30 days; if it upholds the denial you can request an independent external review within 4 months.
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.

- 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.
