How to Get Gattex (Teduglutide) Covered by UnitedHealthcare in California: Appeals, Forms & Timelines

Answer Box: Getting Gattex Covered by UnitedHealthcare in California

UnitedHealthcare requires prior authorization for Gattex (teduglutide) with strict medical necessity criteria: documented short bowel syndrome, ≥12 months of parenteral nutrition dependence (≥3 days/week), recent colonoscopy, and specialist involvement. If denied, California residents can appeal internally, then request an Independent Medical Review through the DMHC, which overturns ~55-70% of medical necessity denials. First step: Gather PN logs, surgical records, and colonoscopy results before submitting your PA request through the UHC provider portal.

UnitedHealthcare's Gattex Coverage Requirements

UnitedHealthcare classifies Gattex as a specialty medication requiring prior authorization through OptumRx. Here's what you need to qualify:

Core Medical Necessity Criteria

Requirement What It Means Documentation Needed
SBS Diagnosis Documented short bowel syndrome Surgical history, imaging, or small bowel length <200 cm
PN Dependence Parenteral nutrition ≥3 days/week for ≥12 months PN/IV logs showing volume and frequency
Colonoscopy Recent screening within 6 months Report with polyp removal if present
Specialist Care Gastroenterologist involvement Prescription from or consultation with GI specialist
Age/Weight ≥1 year old, typically ≥10 kg Medical records confirming age and weight
Exact Dosing 0.05 mg/kg/day subcutaneously Weight-based calculation documentation

Approval Duration: Initial authorization for 12 months if criteria are met.

Note: State mandates and member-specific benefit plans may override these national criteria. Always check your specific plan documents.

Read the Denial: Decode Reason Codes

When UnitedHealthcare denies Gattex, the denial letter will specify the exact reason. Common codes include:

  • Medical Necessity: Insufficient evidence of SBS or PN dependence
  • Step Therapy: Must try less expensive alternatives first
  • Non-Formulary: Drug not on preferred list for your plan
  • Quantity Limits: Requested amount exceeds plan limits
  • Site of Care: Must use OptumRx specialty pharmacy

Extract three key pieces from your denial:

  1. Specific reason code (quote this in your appeal)
  2. Appeal deadline (typically 180 days for commercial plans)
  3. Required documentation listed in the denial

Fixable Causes: Missing Documents & Quick Wins

Before filing a formal appeal, check if your denial stems from easily correctable issues:

Missing Documentation Checklist

  • Complete PN logs showing ≥12 months, ≥3 days/week
  • Colonoscopy report dated within 6 months
  • GI specialist consultation note or prescription
  • Weight-based dosing calculation (0.05 mg/kg/day)
  • ICD-10 diagnosis code for short bowel syndrome
  • Prior therapy documentation (attempts to optimize enteral nutrition)

Quick Administrative Fixes

Coding Mismatch: Ensure your provider used the correct ICD-10 code for SBS and that Gattex is billed under the right benefit (usually pharmacy, not medical).

Formulary Issues: Request a formulary exception if Gattex is non-formulary, emphasizing failed alternatives and contraindications.

Specialty Pharmacy: Confirm the prescription routes through OptumRx or another contracted specialty pharmacy.

First-Level Appeal: Building Your Case

Step-by-Step Appeal Process

  1. Submit within deadline (typically 180 days from denial)
  2. Use UHC provider portal or mail to address on denial letter
  3. Include complete medical records supporting each criterion
  4. Request peer-to-peer review if initial appeal is denied
  5. Track via portal and follow up weekly

Medical Necessity Letter Essentials

Your gastroenterologist should include:

Patient History: Document SBS etiology (surgical resection length, underlying condition), current symptoms, and functional limitations.

PN Dependence Evidence: Specific volume (liters/week), frequency (days/week), duration (months/years), and complications from long-term PN use.

Failed Alternatives: Detail attempts to optimize enteral nutrition, antimotility agents, and other SBS management strategies.

Clinical Rationale: Explain why Gattex is medically necessary, referencing FDA labeling and clinical guidelines.

Monitoring Plan: Outline how treatment response will be measured (PN reduction targets, nutritional status, quality of life).

Peer-to-Peer Review Process

If your initial appeal is denied, request a peer-to-peer review between your gastroenterologist and UnitedHealthcare's medical director. UHC offers electronic P2P requests through their provider portal.

Preparing for the Call

Clinical Summary: Have a 2-3 minute summary ready covering diagnosis, severity, prior treatments, and why Gattex is necessary.

Guidelines Ready: Reference specific sections of gastroenterology society guidelines supporting Gattex use in SBS.

Outcome Goals: Clearly state expected benefits (PN reduction, fewer hospitalizations, improved quality of life).

Risk of Denial: Articulate specific harms from continued PN dependence (line infections, liver dysfunction, access complications).

California External Review: DMHC Independent Medical Review

If UnitedHealthcare upholds their denial after internal appeals, California residents can request an Independent Medical Review through the Department of Managed Health Care.

DMHC IMR Success Rates

Recent data shows California's IMR program has high overturn rates for specialty drug denials:

  • Medical necessity denials: 55.3% overturned by DMHC in 2023
  • Experimental/investigational: ~49% overturned for Anthem Blue Cross
  • Additional reversals: 25.5% of plans reversed their decision once IMR was filed

IMR Process & Timeline

  1. File grievance with UHC (unless urgent)
  2. Wait 30 days for plan response (72 hours for urgent)
  3. Submit IMR application to DMHC if denial upheld
  4. DMHC review: Standard IMR decided within 30 days; expedited within 3-7 days
  5. Binding decision: UHC must comply with IMR determination

Cost: No fee for IMR requests; UHC pays for the review.

For help with the process, contact the DMHC Help Center at (888) 466-2219.
