Why Myths About Specialty Drug Coverage Persist
When you're facing a cancer diagnosis and need expensive specialty drugs like Cabometyx (cabozantinib), misinformation spreads quickly. Patients share outdated experiences, well-meaning friends offer advice based on different insurers, and even some healthcare staff repeat myths they've heard rather than current policy facts.
The stakes are too high for guesswork. Cabometyx can cost over $15,000 per month, and Aetna CVS Health has specific, documented criteria that determine approval. Understanding the real process—not the myths—can mean the difference between getting your medication quickly or facing months of delays.
The truth is: Aetna CVS Health follows predictable, published guidelines for Cabometyx coverage. When you know the actual requirements and submit complete documentation, approval rates improve dramatically.
Myth vs. Fact: Common Misconceptions
Myth 1: "If my oncologist prescribes Cabometyx, Aetna has to cover it"
Fact: Prior authorization is mandatory for Cabometyx under all Aetna CVS Health plans. Your doctor's prescription starts the process but doesn't guarantee coverage. Aetna requires specific clinical documentation proving medical necessity before approval.
Myth 2: "I can substitute Cabometyx tablets with cabozantinib capsules to save money"
Fact: This is dangerous and will be denied. Cabometyx tablets and Cometriq capsules are not bioequivalent and have different FDA-approved indications. Tablets are for renal cell carcinoma and hepatocellular carcinoma; capsules are only for medullary thyroid cancer. Requesting the wrong formulation guarantees denial.
Myth 3: "Aetna automatically denies expensive cancer drugs to save money"
Fact: Aetna must cover FDA-approved cancer treatments when medical necessity criteria are met. Texas law requires binding external review for medical necessity denials, creating strong incentives for fair initial decisions. The issue isn't automatic denial—it's incomplete documentation.
Myth 4: "If I'm denied, I have to pay out-of-pocket while appealing"
Fact: You can request expedited appeals for urgent cases, with decisions required within 24-72 hours. For ongoing therapy, you may be able to get temporary coverage during appeals. Additionally, Exelixis offers patient assistance programs that can help with costs during coverage disputes.
Myth 5: "Step therapy means I have to fail multiple drugs first"
Fact: Step therapy requirements vary by your specific cancer type and treatment history. If you've already tried and failed standard therapies, or have contraindications, this should be documented to bypass step therapy. Aetna's clinical policies consider prior treatment failures and medical contraindications.
Myth 6: "Appeals take months and rarely work"
Fact: In Texas, internal appeals must be decided within 30-60 days for standard cases, and external reviews within 20 days. Success rates improve significantly with proper documentation. The key is submitting complete medical records, not just repeating the original request.
Myth 7: "I need a lawyer to appeal an Aetna denial"
Fact: Texas provides free resources for insurance appeals. The Texas Department of Insurance offers guidance, forms, and a consumer hotline (1-800-252-3439). You can represent yourself in most cases, especially with proper documentation from your oncologist.
What Actually Influences Cabometyx Approval
Understanding Aetna's actual decision-making criteria helps you submit winning requests from the start.
Clinical Documentation Requirements
Diagnosis and Indication: Your oncologist must clearly document your cancer type with supporting pathology reports and confirm it matches FDA-approved Cabometyx indications. For renal cell carcinoma, hepatocellular carcinoma, or differentiated thyroid cancer, include ICD-10 codes and staging information.
Prior Therapy Documentation: Aetna requires evidence of previous treatments tried, duration, and outcomes. This includes:
- Treatment names, dates, and dosing
- Reason for discontinuation (progression, intolerance, contraindications)
- Supporting lab values or imaging showing treatment failure
- Documentation of why standard first-line options aren't appropriate
Imaging and RECIST Criteria: Recent imaging reports with objective measurements using RECIST (Response Evaluation Criteria in Solid Tumors) are essential. Aetna wants to see measurable disease progression or response data, not just clinical impressions.
Submission Process Details
Portal Requirements: Submit through Availity provider portal or your EMR system at least two weeks before planned therapy. Include all requested clinical information to avoid delays.
Drug Interaction Review: Document review of current medications for potential interactions with Cabometyx, demonstrating safety considerations have been addressed.
Duration and Reauthorization: Initial approvals are typically for up to 12 months. Reauthorization requires proof of continued benefit without unacceptable toxicity or disease progression.
From our advocates: We've seen denials overturned simply by including complete prior therapy records. One patient's initial request was denied for "insufficient documentation," but when the oncologist submitted detailed records of three failed previous treatments with dates and imaging, the same request was approved within 48 hours. The medical facts hadn't changed—just the completeness of the submission.
Avoid These Preventable Coverage Mistakes
1. Submitting Incomplete Prior Authorization Requests
The mistake: Sending basic prescription information without comprehensive clinical documentation.
The fix: Use Aetna's prior authorization form and include all required attachments: medical necessity letter, clinical notes, imaging reports, lab results, and prior therapy records.
2. Missing Urgent Request Designations
The mistake: Submitting routine requests when clinical circumstances warrant expedited review.
The fix: If treatment delays could harm your health, have your oncologist mark the request as urgent and provide clinical justification. Aetna must respond within 24 hours for urgent requests.
3. Inadequate Medical Necessity Letters
The mistake: Generic letters that don't address Aetna's specific criteria or your individual clinical situation.
The fix: Ensure your oncologist's letter addresses why Cabometyx is necessary for your specific cancer type, why alternatives aren't appropriate, and includes supporting literature or guidelines when relevant.
4. Ignoring Formulation Requirements
The mistake: Requesting cabozantinib capsules when you need tablets (or vice versa) without proper clinical justification.
The fix: Match your cancer diagnosis to the correct FDA-approved formulation. If you need a non-standard formulation, provide detailed medical rationale for the exception.
5. Failing to Track Appeal Deadlines
The mistake: Missing Texas's 180-day appeal deadline or not following up on pending requests.
The fix: Document all submission dates, track response timelines, and set calendar reminders for appeal deadlines. Contact Counterforce Health if you need help managing complex appeal processes and deadlines.

Texas Appeal Rights and Resources
If your initial request is denied, Texas law provides strong appeal rights specifically for medical necessity disputes.
Internal Appeal Process
You have 180 days from denial to file an internal appeal with Aetna. Include:
- Written explanation of why the denial was incorrect
- Additional clinical documentation supporting medical necessity
- Any new information not included in the original request
Aetna must respond within 30-60 days for standard appeals, or 36-72 hours for urgent cases.
External Independent Review
If your internal appeal is denied, Texas guarantees access to binding external review by an Independent Review Organization (IRO) for medical necessity denials. This review:
- Is conducted by independent medical experts
- Results in binding decisions Aetna must follow
