Who Should Use This Guide

This guide is for Washington residents with advanced Parkinson's disease whose doctors are considering Duopa (carbidopa/levodopa enteral suspension) and who have Blue Cross Blue Shield coverage through:

  • Regence BlueShield (including UMP/PEBB/SEBB plans)
  • Premera Blue Cross
  • Other BCBS Association plans in Washington

Expected outcome: With proper documentation, most patients meeting clinical criteria can get Duopa approved, though the process typically takes 2-4 weeks for initial review.

Member & Plan Basics

Verify Your Coverage

Before starting the prior authorization process:

  • Confirm active BCBS coverage and that your plan includes prescription drug benefits
  • Check if you have a deductible that applies to specialty medications (Duopa costs approximately $7,000+ monthly)
  • Verify your plan type: HMO plans may require primary care referral to neurology first
Tip: Call the member services number on your insurance card to confirm specialty drug coverage and any specific requirements for your plan.

Plan-Specific Requirements

Different Washington BCBS plans have varying processes:

  • Regence BlueShield UMP plans: ArrayRx manages pharmacy benefits (1-888-361-1611)
  • Premera HMO: Requires primary care referral before specialty prescriptions
  • All plans: Prior authorization mandatory for Duopa

Clinical Criteria for Approval

Blue Cross Blue Shield requires comprehensive documentation proving medical necessity for Duopa. The key criteria include:

Primary Requirements

  1. Confirmed Parkinson's disease diagnosis (ICD-10: G20) with motor fluctuations
  2. Advanced disease with significant "OFF" time (≥2-3 hours daily despite optimal oral therapy)
  3. Failed or inadequate response to optimized oral carbidopa/levodopa and adjunct medications
  4. Demonstrated levodopa responsiveness during "ON" periods
  5. Surgical candidacy for PEG-J tube placement

Step Therapy Documentation

You must show trials of conventional treatments, including:

  • Carbidopa/levodopa (immediate and extended-release formulations)
  • At least one adjunct medication: MAO-B inhibitors (rasagiline, selegiline) or COMT inhibitors (entacapone, tolcapone)
  • Documentation of inadequate response, intolerance, or contraindications to each tried therapy
Clinician Corner: Movement disorder specialists should document specific doses, duration of trials, and objective measures of response (e.g., UPDRS scores, patient diaries showing OFF time).

Coding & Billing Requirements

Essential Codes

  • ICD-10: G20 (Parkinson's disease)
  • HCPCS: J7340 (carbidopa 5 mg/levodopa 20 mg enteral suspension, 1 unit = 100 mL cassette)
  • Billing: Claims submitted under Medicare Part B or commercial medical benefit (not pharmacy benefit)

Units and Dosing

  • Typical dosing: 1 cassette per day (some patients require more)
  • Billing units: Each 100 mL cassette = 1 unit of J7340
  • Documentation must include: Total daily dose, morning bolus amount, continuous infusion rate

Documentation Packet Checklist

Required Clinical Documentation

  • Neurology consultation notes from past 6 months
  • Parkinson's disease diagnosis with disease duration and progression
  • Current medication list with doses and response/tolerability
  • Objective OFF time documentation (patient diary, UPDRS scores)
  • Functional impact assessment (ADL limitations during OFF periods)
  • Prior therapy failure documentation (specific medications, doses, duration, reasons for discontinuation)

Surgical Evaluation

  • Gastroenterology consultation confirming PEG-J candidacy
  • Pre-surgical clearance and any relevant imaging
  • Assessment of contraindications to enteral tube placement

Provider Requirements

  • Prescription signed by neurologist or movement disorder specialist
  • Medical necessity letter addressing each coverage criterion
  • Treatment plan with dosing, monitoring, and therapeutic goals

Submission Process

Prior Authorization Steps

  1. Complete BCBS prior authorization form (obtain current version from provider portal)
  2. Submit via designated channel:
    • Electronic: Through BCBS provider portal or Availity
    • Fax: To number specified on PA form (verify current fax number)
  3. Include all required attachments from documentation checklist
  4. Request expedited review if clinically urgent (decision within 72 hours)
Note: Standard prior authorization decisions typically take 5-15 business days. Incomplete submissions cause delays.

Common Rejection Reasons

  • Incomplete clinical documentation
  • Missing step therapy failure evidence
  • Lack of specialist evaluation
  • Incorrect coding or billing information

Specialty Pharmacy Coordination

Duopa must be dispensed through approved specialty pharmacies. AbbVie's preferred network includes:

  • Pharmacy Solutions (AbbVie's specialty pharmacy)
  • Accredo Specialty Pharmacy
  • CVS Specialty

Coordination Steps

  1. Complete DuoConnect enrollment form with pharmacy preference
  2. Verify specialty pharmacy is in BCBS network
  3. Coordinate benefit verification between pharmacy, provider, and insurer
  4. Arrange pump training and delivery logistics

The specialty pharmacy will handle much of the prior authorization coordination, but ensure your provider submits complete clinical documentation.

After Submission: What to Expect

Timeline

  • Initial review: 5-15 business days
  • Expedited review: 72 hours (if urgent)
  • Additional information requests: May extend timeline 5-10 days

Status Tracking

  • Record confirmation numbers from all submissions
  • Check status through BCBS provider portal or member services
  • Maintain copies of all correspondence

If Approved

  • Specialty pharmacy will contact you to arrange delivery and training
  • Coordinate PEG-J placement with gastroenterology
  • Schedule pump training and ongoing support

Appeals Process in Washington

If your initial prior authorization is denied, Washington provides robust appeal rights:

Internal Appeals

  1. File within 60 days of denial notice
  2. Submit additional clinical evidence supporting medical necessity
  3. Request peer-to-peer review with BCBS medical director
  4. Decision within 15-30 days depending on plan type

External Review (Independent Review Organization)

If internal appeals fail:

  1. Request external review within 60 days of final internal denial
  2. Washington assigns independent medical experts to review your case
  3. Submit additional evidence within 5 business days of IRO assignment
  4. Decision timeline:
    • Standard: 20 days (fully-insured plans) or 45 days (self-insured)
    • Expedited: 72 hours if urgent
Important: External review decisions are binding on your insurer. Contact Washington Office of the Insurance Commissioner at 1-800-562-6900 for assistance.

Appeals Documentation

  • Copy of original denial letter
  • All clinical records supporting medical necessity
  • Evidence of failed alternative treatments
  • Provider letter explaining why Duopa is medically necessary

Common Pitfalls to Avoid

1. Insufficient Step Therapy Documentation

Problem: BCBS denies because oral medication trials aren't adequately documented. Solution: Provide detailed records of each medication tried, including specific doses, duration, and reasons for failure/intolerance.

2. Missing Specialist Evaluation

Problem: Prior authorization submitted by primary care without movement disorder specialist input. Solution: Ensure neurologist or movement disorder specialist evaluates patient and signs prescription.

3. Incomplete Surgical Assessment

Problem: No documentation of PEG-J candidacy or surgical clearance. Solution: Obtain gastroenterology consultation confirming surgical candidacy before PA submission.

4. Wrong Billing Channel

Problem: Submitting to pharmacy benefit instead of medical benefit. Solution: Duopa is billed under medical benefit with HCPCS J7340, not through pharmacy formulary.

5. Inadequate Functional Impact Documentation

Problem: Clinical notes don't clearly show how OFF time affects daily activities. Solution: Document specific examples of functional limitations and safety concerns during OFF periods.

Costs & Patient Assistance

Insurance Coverage

  • Typical copay: Varies by plan; specialty tier copays can be $100-500+ monthly
  • Deductible: May apply if not met; Duopa costs ~$7,000+ monthly without coverage

FAQ

How long does BCBS prior authorization take in Washington? Standard review takes 5-15 business days. Expedited review (for urgent cases) takes up to 72 hours. Incomplete submissions extend timelines.

What if Duopa isn't on my BCBS formulary? Duopa typically requires prior authorization rather than formulary placement. Your doctor can request a formulary exception with medical necessity documentation.

Can I appeal if my doctor isn't a movement disorder specialist? Yes, but appeals are stronger with specialist evaluation. Consider getting a consultation with a movement disorder neurologist to support your case.

Does step therapy apply if I tried medications outside Washington? Yes, document all prior therapies regardless of where they were tried. Out-of-state medical records are acceptable evidence.

What's the difference between internal and external appeals? Internal appeals are reviewed by BCBS staff. External appeals are reviewed by independent medical experts assigned by Washington state and are binding on the insurer.

How do I request expedited review? Your doctor must document that delay would seriously jeopardize your health or ability to function. Submit this with your PA request or appeal.

From our advocates: We've seen patients successfully overturn Duopa denials by working closely with their movement disorder specialist to document specific functional limitations during OFF periods. One patient's detailed diary showing falls and inability to perform work tasks during OFF time was crucial evidence that helped secure approval on appeal. Remember, concrete examples of how symptoms affect daily life often carry more weight than general medical descriptions.

Getting denied for a medication you need can feel overwhelming, but Washington residents have strong appeal rights and support systems. Counterforce Health helps patients, clinicians, and specialty pharmacies turn insurance denials into targeted, evidence-backed appeals by analyzing denial letters, plan policies, and clinical notes to draft point-by-point rebuttals aligned with each plan's specific requirements.

The platform pulls the right evidence citations—FDA labeling, peer-reviewed studies, and specialty guidelines—and weaves them into appeals with required clinical facts like diagnosis codes, prior treatment failures, and dosing rationale. For complex therapies like Duopa, this systematic approach to appeals can make the difference between denial and approval.

If you're facing a denial, don't give up. Washington's external review process provides an independent medical opinion that's binding on your insurer. With proper documentation and persistence, most patients who meet clinical criteria can ultimately get Duopa covered. Work closely with your movement disorder specialist, use Counterforce Health's resources if needed, and remember that the Washington Office of the Insurance Commissioner is available to help guide you through the appeals process.
