Set Your Goal: Understanding BCBS PA Requirements

Blue Cross Blue Shield plans in Washington—including Premera Blue Cross and Regence BlueShield—require prior authorization for Gattex (teduglutide) before coverage begins. Your insurance will deny claims submitted without an approved PA, leaving you with potential out-of-pocket costs exceeding $46,000 per month.

Coverage Requirements at a Glance

Requirement What It Means Documentation Needed
Diagnosis Confirmed short bowel syndrome Surgical reports, imaging, ICD-10 codes
Age 1 year or older Birth certificate or medical records
Specialist Care Prescribed by/with gastroenterologist Provider credentials, consultation notes
PN Dependence 12+ months parenteral nutrition Weekly PN logs, infusion schedules
Enteral Optimization Failed conventional approaches Diet trials, formula changes, outcomes
Baseline Assessment Recent colonoscopy (adults) or FOBT Procedure reports within policy timeframe
Dosing FDA-approved range (≤0.05 mg/kg/day) Weight documentation, dosing calculations

Your partnership with your gastroenterologist is essential—they understand both the clinical complexity of short bowel syndrome and the administrative requirements insurers demand.

Visit Preparation: What to Document

Before meeting with your provider, create a comprehensive timeline that demonstrates medical necessity. Insurance reviewers look for clear patterns of dependence and failed alternatives.

Symptom and Treatment Timeline

Document these key elements in chronological order:

Original Diagnosis and Surgery:

  • Date and type of bowel resection
  • Remaining intestinal length (if known)
  • Surgical complications or additional procedures
  • Post-operative recovery challenges

Parenteral Nutrition History:

  • Start date of PN therapy
  • Current weekly frequency (days per week)
  • Weekly volume requirements
  • Any attempts to reduce or wean PN
  • Complications from central line access

Enteral Nutrition Attempts:

  • Specialized formulas tried (elemental, semi-elemental, MCT-based)
  • Dietary modifications implemented
  • Small, frequent meal strategies
  • Outcomes and tolerance issues
  • Reasons for discontinuation

Current Functional Impact:

  • Daily life limitations
  • Work or school disruptions
  • Quality of life concerns
  • Caregiver burden (especially for pediatric patients)
Tip: Use a simple spreadsheet or timeline format. Insurance reviewers appreciate clear, chronological documentation that shows the progression from initial treatment through current needs.

Building Your Evidence Kit

Your gastroenterologist will need comprehensive documentation to build a compelling medical necessity case. Gather these materials before your appointment:

Clinical Documentation

  • Complete surgical records from bowel resection procedures
  • Hospital discharge summaries detailing post-operative course
  • Laboratory results showing nutritional deficiencies or malabsorption markers
  • Imaging studies (CT scans, contrast studies) showing anatomy
  • Growth charts for pediatric patients
  • Recent colonoscopy report (adults) or fecal occult blood test results

Treatment History

  • PN prescription records with dates, volumes, and frequencies
  • Home infusion company records documenting actual usage
  • Nutrition consultation notes detailing enteral optimization attempts
  • Pharmacy records showing specialized formula trials
  • Weight logs demonstrating nutritional status over time

Regulatory Support

Your provider may reference these evidence sources in the medical necessity letter:

Medical Necessity Letter Structure

Work with your gastroenterologist to ensure the medical necessity letter addresses every BCBS requirement systematically. Here's the framework that increases approval odds:

Essential Components Checklist

Patient Information and Diagnosis:

  • Confirmed short bowel syndrome diagnosis with ICD-10 code K91.2
  • Etiology (surgical resection, congenital anomaly, etc.)
  • Remaining intestinal anatomy and length (if known)
  • Age confirmation (≥1 year old)

Clinical Rationale:

  • Duration of parenteral nutrition dependence (≥12 months)
  • Current PN frequency and weekly volume requirements
  • Baseline nutritional status and monitoring parameters
  • Evidence of intestinal failure despite medical management

Prior Treatment Attempts:

  • Comprehensive list of enteral nutrition strategies attempted
  • Specialized formulas trialed with specific names and durations
  • Dietary modifications implemented
  • Outcomes and reasons for inadequacy or failure

Safety Assessment:

  • Recent appropriate screening (colonoscopy for adults, FOBT for children)
  • Absence of contraindications (active malignancy, etc.)
  • Weight documentation for dosing calculations
  • Provider qualifications and gastroenterology expertise

Treatment Plan:

  • Requested dose within FDA-approved range
  • Monitoring plan for efficacy and safety
  • Goals for parenteral nutrition reduction
  • Timeline for reassessment

Sample Clinical Narrative

"This 34-year-old patient with documented short bowel syndrome secondary to massive small bowel resection following mesenteric ischemia has required parenteral nutrition support for 18 months, currently receiving 5 infusions weekly totaling 2,100 mL. Despite optimization of enteral feeding protocols including trials of Vivonex T.E.N., Peptamen AF, and dietary modifications with small frequent meals, adequate hydration and nutrition cannot be maintained without parenteral support. Recent colonoscopy performed on [date] revealed [findings] with appropriate management. The patient meets all FDA-approved criteria for Gattex therapy at 0.05 mg/kg/day subcutaneously, with the goal of reducing parenteral dependence and improving quality of life."

Peer-to-Peer Review Support

If BCBS requests a peer-to-peer (P2P) review, your gastroenterologist will speak directly with the insurance company's medical director. You can support this process:

Before the P2P Call

  • Provide availability windows: Offer your provider 2-3 time slots when you're available for questions
  • Prepare a case summary: One-page overview highlighting key approval criteria
  • Gather recent labs: Ensure nutritional markers are current and available
  • Identify talking points: Emphasize failed enteral strategies and PN reduction goals

P2P Success Factors

Successful peer-to-peer conversations typically emphasize:

  • Clinical expertise: Your provider's experience managing short bowel syndrome
  • Patient-specific factors: Unique anatomical or medical considerations
  • Evidence base: FDA approval data and clinical trial outcomes
  • Quality of life impact: Functional limitations and caregiver burden
From our advocates: "We've seen P2P reviews succeed when the gastroenterologist focuses on specific failed enteral strategies rather than general statements. Mentioning exact formula names, trial durations, and measurable outcomes—like persistent high-output ostomy volumes despite optimization—helps medical directors understand why standard approaches weren't adequate."

After Your Visit: Documentation and Follow-Up

Maintain organized records and clear communication channels with your provider's office throughout the PA process.

What to Save

  • Copy of the medical necessity letter before submission
  • PA submission confirmation (reference number, date, method)
  • All correspondence from BCBS regarding the request
  • Timeline tracking showing submission and response dates
  • Contact information for appeals if needed

Portal Communication Best Practices

When messaging your provider through patient portals:

  • Be specific: Reference PA submission dates and confirmation numbers
  • Include context: Attach relevant BCBS correspondence
  • Ask direct questions: "Has the PA been approved?" rather than general status inquiries
  • Respect response times: Allow 2-3 business days for non-urgent communications

Respectful Persistence and Escalation

PA decisions can take 15-30 days. Maintain appropriate follow-up without overwhelming your provider's office.

Follow-Up Cadence

  • Week 1: Confirm submission with reference number
  • Week 2: Check for any requests for additional information
  • Week 3: Inquire about preliminary feedback or timeline updates
  • Week 4+: Discuss backup plans if denial occurs

When to Escalate Politely

Contact your provider if:

  • No response after published timeline (typically 15 business days)
  • BCBS requests information you believe was already submitted
  • You receive a denial letter with unclear reasoning
  • Time-sensitive medical needs require expedited processing

Washington State Appeals Process

Washington residents have strong appeal rights if BCBS denies your Gattex PA request. The state's external review process provides independent medical oversight.

Internal Appeals Process

First Level (Required):

  • File within 180 days of denial
  • Submit through BCBS member portal or written request
  • Include additional clinical documentation
  • Decision within 30 days (15 days for expedited)

  • Same timeline and submission requirements
  • Often involves different medical reviewers

External Review Through IRO

After exhausting internal appeals, request an Independent Review Organization (IRO) evaluation:

Process:

  • Request through BCBS (they must facilitate)
  • Washington Office of the Insurance Commissioner assigns IRO from certified registry
  • BCBS provides all medical records within 3 business days
  • You have 5+ business days to submit additional information

Timeline:

  • Standard review: 20 days maximum for fully-insured plans
  • Expedited review: 72 hours for urgent cases

Decision:

  • IRO decision is final and binding on BCBS
  • If approved, BCBS must immediately provide coverage
  • If denied, consider complaint to Washington Insurance Commissioner

FAQ

How long does Blue Cross Blue Shield PA take in Washington? Standard PA decisions are typically made within 15 business days. Expedited requests (for urgent medical needs) must be decided within 72 hours under Washington state law.

What if Gattex is non-formulary on my BCBS plan? Non-formulary medications can still receive coverage through the formulary exception process. Your provider will need to demonstrate medical necessity and that preferred alternatives are inappropriate.

Can I request an expedited appeal in Washington? Yes, if delay in treatment could seriously jeopardize your health or functional ability. Both internal appeals and external IRO reviews offer expedited timelines for urgent cases.

Does step therapy apply if I've failed treatments outside Washington? Treatment history from other states should be accepted if properly documented. Ensure your gastroenterologist includes comprehensive records of prior therapy attempts regardless of location.

What happens if my employer plan is self-funded? Self-funded ERISA plans may not be subject to Washington state appeal laws. However, many voluntarily provide similar processes, and you can contact the U.S. Department of Labor for ERISA-specific guidance.

How much does Gattex cost without insurance? Wholesale acquisition cost is approximately $46,893 per 30-vial kit or $1,798 per single vial (June 2024 pricing). Patient assistance programs may significantly reduce costs for eligible individuals.
