Why Myths About Enhertu Coverage Persist

Getting Enhertu (fam-trastuzumab deruxtecan-nxki) approved by UnitedHealthcare can feel overwhelming, especially when misinformation spreads through patient forums and even well-meaning healthcare staff. These myths persist because insurance coverage rules change frequently, oncology treatments are complex, and the stakes feel impossibly high when you're facing cancer.

The reality is that UnitedHealthcare has specific, documented requirements for Enhertu approval—and understanding these facts can dramatically improve your chances of getting covered. In Virginia, you also have strong consumer protections through the State Corporation Commission that many patients don't know about.

Let's separate fact from fiction so you can focus your energy on what actually works.

Common Myths vs. Facts

Myth 1: "If my oncologist prescribes Enhertu, UnitedHealthcare has to cover it"

Fact: UnitedHealthcare requires prior authorization for Enhertu regardless of your doctor's prescription. As of October 2024, Enhertu is explicitly listed as requiring PA for commercial plans. Your oncologist must submit clinical documentation proving you meet specific criteria before coverage begins.

Myth 2: "I need to try cheaper drugs first because of step therapy"

Fact: Step therapy requirements vary by your specific cancer type and treatment history. For HER2-positive cancers, UnitedHealthcare may require biosimilar trastuzumab (like Kanjinti or Trazimera) before approving Enhertu, but exceptions exist for patients who've already failed or can't tolerate preferred options. Document any intolerance or contraindications to bypass step therapy.

Myth 3: "HER2-low breast cancer isn't covered because it's too new"

Fact: Enhertu is FDA-approved for HER2-low breast cancer, and UnitedHealthcare covers FDA-approved indications when clinical criteria are met. The key is proper documentation of HER2 status through immunohistochemistry (IHC) or in situ hybridization (ISH) testing.

Myth 4: "Denials are final—there's no point in appealing"

Fact: UnitedHealthcare has multiple appeal levels, and Virginia offers external review through the State Corporation Commission. External reviews in Virginia have specific timelines and are decided by independent medical experts within 45 days. Many denials get overturned with proper documentation.

Myth 5: "I can't get Enhertu at home—it has to be in a hospital"

Fact: UnitedHealthcare covers Enhertu administration in various settings, including physician offices, ambulatory infusion centers, and home infusion when appropriate. Hospital outpatient is required only for medically unstable patients or when intensive monitoring is needed.

Myth 6: "The lung side effects make Enhertu unapprovable"

Fact: UnitedHealthcare covers Enhertu despite the interstitial lung disease (ILD) risk when proper monitoring protocols are in place. Your oncologist must document baseline lung function assessment and commit to regular monitoring, but this doesn't prevent approval.

Myth 7: "Generic alternatives work just as well, so insurance won't cover the brand"

Fact: There is no generic version of Enhertu. While UnitedHealthcare prefers biosimilar alternatives for some HER2 therapies, Enhertu (trastuzumab deruxtecan) is a unique antibody-drug conjugate with no direct generic equivalent.

Myth 8: "If I'm denied once, I have to wait months to reapply"

Fact: You can immediately appeal a denial or resubmit with additional documentation. Virginia law gives you 120 days from the final internal denial to request external review, and urgent cases can be expedited to 72 hours.

What Actually Influences Approval

Understanding what UnitedHealthcare actually looks for can transform your approval odds. Here's what matters:

Clinical Documentation Requirements

HER2 Status Verification: UnitedHealthcare requires clear documentation that your cancer is HER2-positive through IHC 3+ or ISH positive testing. Include the actual pathology report, not just a summary.

Treatment History: Document all prior HER2-targeted therapies, including dates, duration, response, and reasons for discontinuation (progression, intolerance, contraindication).

Diagnosis and Staging: Include specific cancer type, stage, and ICD-10 codes. Enhertu is approved for multiple HER2-positive cancers—breast, gastric, lung, and others.

Risk Mitigation Documentation

Because of Enhertu's ILD risk, your oncologist must demonstrate:

  • Baseline pulmonary assessment (chest imaging, pulmonary function if indicated)
  • Plan for regular monitoring (typically chest CT every 12 weeks)
  • Patient education about respiratory symptoms to report
  • Commitment to immediate drug discontinuation if ILD develops

Routing and Submission Process

Use the Right Channel: Submit via the UnitedHealthcare Provider Portal using the Specialty Pharmacy Transactions tile. Phone submissions may cause delays.

Complete Information: Incomplete submissions are the top cause of delays. Include all required clinical notes, lab results, imaging, and prior treatment records upfront.

Top 5 Preventable Mistakes to Avoid

1. Submitting Without HER2 Test Results

The most common denial reason is missing or inadequate HER2 biomarker documentation. Always include the complete pathology report showing IHC score or ISH ratio.

2. Ignoring Step Therapy Requirements

If you haven't tried preferred HER2 therapies, document medical reasons why they're inappropriate rather than ignoring the requirement entirely.

3. Incomplete ILD Risk Assessment

Failing to address interstitial lung disease monitoring leads to denials. Include baseline chest imaging and a monitoring plan in your initial submission.

4. Wrong Site of Care Request

Requesting hospital-based infusion without medical justification when outpatient or home infusion is appropriate can trigger denials.

5. Missing Appeal Deadlines

Virginia gives you 120 days for external review, but internal appeals have shorter deadlines. Track all dates and submit appeals promptly with complete documentation.

From our advocates: We've seen patients succeed by creating a simple checklist before any PA submission: HER2 test results ✓, prior treatment summary ✓, baseline chest CT ✓, monitoring plan ✓. This systematic approach prevents the most common denial reasons and speeds approval.
