Humana

Humana operates Medicare Advantage contract H0630 as a HMO plan, one of hundreds of MA organizations whose prior authorization and claim-denial behavior is tracked through CMS Office of Inspector General audits and the KFF Medicare Advantage analysis. In the most recent reporting window, Humana processed 1,450,000 prior authorization requests, approving 1,299,200 and denying 150,800 — a denial rate of 10.4%. Prior authorization is the process by which Medicare Advantage plans require plan-level approval before covering specific services, medications, or procedures — a workflow that does not exist in traditional fee-for-service Medicare.

Of the denials issued by Humana, 22,620 were appealed by beneficiaries or providers, and 15,382 of those appeals were overturned — an overturn rate of 68.0%. A high overturn rate is meaningful because the CMS Office of Inspector General flagged it as a sign that initial denials may have been issued incorrectly or based on internal clinical criteria stricter than traditional Medicare's coverage rules. When an appeal reverses a denial, the plan ultimately pays for the care it initially refused, which suggests the original denial was not supported when reviewed more carefully. For Humana specifically, more than half of appealed denials are overturned, meaning persistence pays off for beneficiaries.

Practical takeaway for beneficiaries enrolled in or considering Humana: if you receive a prior authorization denial, you have formal appeal rights under CMS Medicare Advantage rules — first through the plan itself, then to an independent review entity, and further through administrative law judges if needed. Do not abandon the appeal because the plan's first decision was unfavorable; the nationwide overturn pattern strongly suggests that appealing is often worthwhile. Data here reflects aggregate plan behavior, not individual case outcomes — your specific denial will depend on the service requested, clinical documentation, and CMS national coverage determinations.
