Coverage Basics: Is Gattex Covered by Humana?

Yes, Humana Medicare Advantage and Part D plans cover Gattex (teduglutide), but it requires prior authorization due to its high cost (~$46,893 per 30-vial kit) and specialty status. Humana requires clinical pharmacy review for all high-cost specialty medications to verify appropriate use and medical necessity.

Coverage at a Glance

Requirement What It Means Where to Find It
Prior Authorization Required before dispensing Humana Provider Portal
Formulary Status Covered with restrictions 2026 Drug List
Step Therapy Must try enteral feeding first Policy documentation required
Specialist Required Gastroenterologist attestation Clinical notes within 30 days
Diagnosis Code ICD-10 for short bowel syndrome Medical records

Important: Gattex is not exempt from prior authorization requirements, even under Humana's 2026 streamlined policies that eliminate some outpatient authorizations. As a specialty pharmacy benefit, it maintains full review requirements.

  • Submission: Any time during business hours

    • Hospital discharge planning
  • How to Request: Mark "urgent" on submission form and include clinical justification

Clinical Criteria: What Humana Requires for Approval

Primary Requirements

Diagnosis: Confirmed short bowel syndrome with:

  • Appropriate ICD-10 coding
  • Documented bowel resection or congenital condition
  • Specialist (gastroenterologist) evaluation

Parenteral Nutrition Dependence:

  • Adults: ≥12 months of PN ≥3 days per week
  • Pediatric: ≥3 months providing ≥30% of caloric needs
  • Detailed logs showing volumes and frequency

Weight Requirement:

  • Patient weight ≥10 kg
  • Dosing ≤0.05 mg/kg/day subcutaneously

Step Therapy Documentation

Before Gattex approval, you must demonstrate enteral feeding optimization failure:

Strategy Tried Documentation Needed Typical Trial Duration
Continuous enteral feeds Feeding logs, output volumes 2-4 weeks
Polymeric formulas Tolerance notes, weight changes 2-3 weeks
Elemental formulas Stool/ostomy output >2-3L/day 1-2 weeks
Anti-diarrheal medications Medication list, effectiveness Concurrent trial

Key Monitoring Parameters:

  • 24-hour stool/ostomy output volumes
  • Electrolyte stability
  • Nutritional markers (albumin, prealbumin)
  • Liver function tests
From Our Advocates: We've seen the strongest approvals when providers submit a comprehensive "enteral optimization summary" showing specific formulas tried, volumes achieved, and objective measures of intolerance like high-output ostomy volumes or electrolyte imbalances. This documentation style significantly reduces back-and-forth requests for additional information.

Cost Considerations: What You'll Pay

2026 Medicare Part D Changes

  • Out-of-pocket cap: $2,100 maximum annual spending
  • After cap reached: 100% coverage for remainder of year
  • Monthly costs vary by plan tier and deductible status

Financial Assistance Options

  • Takeda Patient Assistance: Income-based support programs
  • Medicare Extra Help: Low-income subsidy program
  • State pharmaceutical assistance: Florida may offer additional programs
  • Manufacturer copay cards: Limited Medicare eligibility

Cost-Saving Tip: If you're approaching the $2,100 cap, coordinate with your pharmacy to optimize timing of fills to maximize the benefit period.

Renewal Requirements: Staying Covered

Reauthorization Timeline

  • Initial approval: Typically 6-12 months
  • Renewal deadline: Submit 30 days before expiration
  • Required documentation: Updated PN logs showing reduction

Success Metrics for Renewal

Primary Goal: ≥20% reduction in weekly PN volume from baseline

Monitoring Requirements:

  • Specialist follow-up every 3-6 months
  • Laboratory monitoring per protocol
  • Adverse event reporting

Common Denial Reasons and Solutions

Based on Humana's ~3.5% denial rate for Medicare Advantage, most denials result from documentation gaps rather than medical necessity questions:

  1. Incomplete PN logs → Submit detailed weekly volumes for required duration
  2. Missing enteral optimization → Document specific formulas tried and intolerance
  3. Insufficient specialist input → Ensure gastroenterologist provides comprehensive evaluation
  4. Baseline data gaps → Complete colonoscopy, labs within required timeframes
  5. Dosing concerns → Verify weight-based dosing calculations
