What Affects Your Approval Timeline

Several factors determine how quickly Humana approves Ruconest (C1 esterase inhibitor) in New York:

Benefit Type: Medicare Advantage plans follow CMS timelines (7 days standard, 72 hours expedited starting January 2026), while commercial plans adhere to New York's stricter 72-hour standard requirement for specialty medications.

Documentation Completeness: Humana requires comprehensive HAE diagnosis documentation, including genetic testing results or C1-INH functional assays, attack frequency records, and detailed prior treatment history. Missing documentation triggers additional information requests that can add 1-7 days.

Step Therapy Requirements: Since January 2022, Humana replaced Ruconest with icatibant as the preferred HAE therapy, requiring documented failure or intolerance of alternatives before approval.

Site of Care Restrictions: Ruconest must be dispensed through Humana's designated specialty pharmacy network and administered by qualified healthcare professionals, requiring coordination that can extend timelines.
