What Affects Approval Timing

Several factors influence how quickly Humana processes your Poteligeo (mogamulizumab-kpkc) prior authorization:

Benefit Type: Poteligeo is billed under Medicare Part B as a buy-and-bill therapy using HCPCS code J9204. This typically moves through medical benefit review rather than pharmacy benefit channels, which can affect processing times.

Complexity of Criteria: Humana requires documentation of relapsed or refractory cutaneous T-cell lymphoma (CTCL) with specific subtypes—mycosis fungoides or Sézary syndrome—after failure of at least one prior systemic therapy. The more complex your treatment history, the longer initial review may take.

Documentation Completeness: Humana's 3.5% denial rate is among the lowest of major insurers, but denials often stem from incomplete documentation rather than medical necessity disputes.

Note: Starting in 2026, new CMS rules will require Humana to respond to electronic prior authorization requests within 7 days (down from the current 14 days), with Humana committing to one-business-day decisions for 95% of complete electronic requests.
