Patient Profile: Understanding Your Diagnosis

If you've been diagnosed with metastatic medullary thyroid carcinoma (MTC), you're dealing with a rare but aggressive form of thyroid cancer. Unlike more common thyroid cancers, MTC doesn't respond to radioactive iodine treatment, making targeted therapies like Cometriq essential for managing disease progression.

Your oncologist has likely confirmed your diagnosis through several key tests:

  • Fine needle aspiration (FNA) biopsy showing characteristic MTC cells
  • Elevated calcitonin levels in your blood (often dramatically high)
  • Imaging studies (CT, MRI, or PET scans) showing metastatic spread
  • Genetic testing for RET mutations (found in about 25% of cases)

These diagnostic elements aren't just medical details—they're the foundation of your insurance approval. Humana requires documentation of progressive, metastatic disease with elevated biomarkers to approve Cometriq coverage.

Pre-Authorization Preparation

Step 1: Gather Essential Documentation

Your healthcare team needs to compile a comprehensive medical file before submitting to Humana:

  • Pathology report using College of American Pathologists (CAP) protocol with MTC confirmation
  • Recent calcitonin and CEA levels (within 90 days)
  • Staging scans showing metastatic disease progression
  • Prior therapy history including any previous treatments and their outcomes
  • Current performance status and treatment goals

Step 2: Medical Necessity Letter Components

Your oncologist's letter to Humana should address these key points:

  • Confirmed diagnosis of progressive, metastatic MTC
  • Documentation that disease is not amenable to surgery or radiation
  • Evidence of elevated calcitonin levels indicating active disease
  • Statement that Cometriq capsules (not Cabometyx tablets) are specifically indicated for MTC
  • Treatment goals and monitoring plan
Clinician Corner: Include specific calcitonin values and trend over time. Humana reviewers look for objective evidence of disease activity, not just imaging progression.

The key is comprehensive documentation that clearly establishes medical necessity.
