What This Guide Covers

This guide helps patients with RET fusion-positive cancers and their healthcare teams navigate Humana's prior authorization process for Retevmo (selpercatinib) in Georgia. Whether you're dealing with non-small cell lung cancer (NSCLC), medullary thyroid cancer, or other RET fusion-positive tumors, we'll walk you through each step to maximize your chances of approval.

Retevmo costs approximately $23,000-$26,000 per month without insurance coverage, making prior authorization essential for most patients. The good news? Humana's denial rate is relatively low at 5.8% for Medicare Advantage plans, and appeals frequently succeed when properly documented.

Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals for patients facing coverage challenges with specialty medications like Retevmo. Their platform helps identify denial reasons and drafts point-by-point rebuttals aligned to each plan's specific requirements.

Before You Start: Verify Your Coverage

Check Your Plan Type

First, confirm whether you have Humana Medicare Advantage, Medicare Part D, or a commercial Humana plan. The prior authorization process varies slightly:

  • Medicare Advantage/Part D: 7-day standard response (14 days pre-2026), 72-hour expedited option
  • Commercial plans: Follow state insurance regulations with 30-day standard timelines

Verify Network Status

Ensure your oncologist and preferred pharmacy are in-network. Out-of-network providers may require additional documentation or face automatic denials.
