How to Use This Decision Tree

This guide helps Georgia patients and their doctors navigate UnitedHealthcare's requirements for Enhertu (fam-trastuzumab deruxtecan-nxki). Work through each section in order—starting with eligibility triage—to identify your strongest path to coverage.

Before you start, gather:

  • Your UnitedHealthcare member ID and policy details
  • Pathology reports showing HER2 status
  • Complete treatment history (medications tried, dates, outcomes)
  • Recent imaging or lab results
  • Any previous denial letters
Tip: Keep copies of all documents. Georgia's external review process requires comprehensive medical records.

Eligibility Triage: Do You Qualify?

Answer these questions to determine your approval likelihood:

1. Diagnosis Confirmed?

You need ONE of these FDA-approved indications:

  • HER2-positive breast cancer (metastatic, after prior HER2 therapy)
  • HER2-low breast cancer (metastatic, hormone receptor-positive must be endocrine therapy refractory)
  • HER2-mutant non-small cell lung cancer (metastatic)
  • HER2-positive gastric or gastroesophageal junction cancer (metastatic)

2. HER2 Status Documented?

Required biomarker testing varies by cancer type:

  • Breast cancer: IHC 3+ or ISH+ (HER2-positive); IHC 1+ or IHC 2+/ISH- (HER2-low)
  • NSCLC: HER2 (ERBB2) mutation via NGS testing
  • Gastric cancer: HER2 overexpression or gene amplification

3. Prior Therapy Requirements Met?

UnitedHealthcare typically requires step therapy:

  • Breast cancer: Prior trastuzumab-based regimen (with or without pertuzumab)
  • NSCLC: May require prior systemic therapy
  • Gastric cancer: Consider HER2 re-testing after prior trastuzumab

4. ILD Risk Assessment Complete?

Mandatory safety requirements:

  • Baseline pulmonary function assessment
  • No active interstitial lung disease
  • Plan for ongoing respiratory monitoring

If "Likely Eligible": Your Approval Checklist

You qualify if you answered "yes" to questions 1-4 above.

Step-by-Step: Fastest Path to Approval

  1. Confirm Prior Authorization Requirement (Day 1)
  2. Gather Clinical Documentation (Days 1-3)
    • HER2 testing results with specific methodology
    • Pathology reports with ICD-10 codes
    • Treatment history with dates and outcomes
    • Baseline pulmonary assessment
  3. Submit Prior Authorization (Day 4)
    • Use UnitedHealthcare Provider Portal
    • Include medical necessity letter from oncologist
    • Attach all supporting documentation
    • Request expedited review if clinically urgent
  4. Track Your Request (Days 5-30)
    • Standard review: 15 business days
    • Expedited review: 72 hours
    • Check status via provider portal

Medical Necessity Letter Checklist

Your oncologist should include:

  • Problem: Specific diagnosis with staging
  • Prior treatments: Medications tried, duration, response/failure
  • Clinical rationale: Why Enhertu is appropriate now
  • Guidelines: Reference to NCCN guidelines or FDA labeling
  • Monitoring plan: ILD surveillance protocol

If "Possibly Eligible": Tests and Timeline

You may qualify but need additional documentation.

Missing HER2 Testing?

  • Breast cancer: Request HER2 testing on most recent tissue sample
  • NSCLC: Order comprehensive genomic profiling (CGP) or targeted HER2 mutation testing
  • Gastric cancer: Consider HER2 re-testing if prior trastuzumab exposure

Unclear Prior Therapy History?

  • Obtain complete treatment records from all providers
  • Document specific failure criteria (progression, intolerance)
  • Include dates and duration of each therapy

Timeline to Re-apply

  • HER2 testing results: 1-2 weeks
  • Medical records collection: 2-4 weeks
  • Resubmit PA: Within 30 days of receiving new documentation

If "Not Yet": Alternatives and Exception Requests

You don't meet standard criteria but may still get coverage.

Discuss These Alternatives

  • Trastuzumab + pertuzumab (if not previously tried)
  • T-DM1 (Kadcyla) for HER2-positive breast cancer
  • Clinical trials through ClinicalTrials.gov

Prepare Exception Requests

  • Document contraindications to preferred alternatives
  • Gather peer-reviewed literature supporting off-label use
  • Consider peer-to-peer review with UnitedHealthcare medical director
Note: Exception requests have lower approval rates but may succeed with compelling clinical evidence.
