Answer Box: Getting Duopa Covered by Aetna in Washington

Duopa (carbidopa/levodopa enteral) requires prior authorization from Aetna in Washington. You must first document failure or intolerance to oral carbidopa/levodopa plus one additional anti-Parkinson agent (COMT inhibitor, dopamine agonist, or MAO-B inhibitor). Submit the Medical Exception/Prior Authorization form via fax (877-269-9916) or online through Availity. If denied, Washington residents can appeal through Aetna's internal process, then request external review through the Washington Insurance Commissioner within 180 days.

First step today: Contact your movement disorder specialist to document your oral medication trials and request the prior authorization form submission.

Plan Types & Network Requirements

Your Aetna plan type determines referral requirements for accessing movement disorder specialists who prescribe Duopa:

Plan Type PCP Required Specialist Referral In-Network Required Duopa Prior Auth
HMO Yes Yes Yes Required
PPO Optional No No (higher cost out-of-network) Required
EPO No No Yes Required

Key considerations for Duopa therapy:

  • HMO members need a primary care referral to see both a gastroenterologist (for PEG-J tube placement) and movement disorder neurologist
  • PPO members can self-refer but pay more for out-of-network specialists
  • EPO members have direct specialist access but must stay in-network for coverage
Tip: Use Aetna's Find a Doctor tool to verify both your movement disorder specialist and gastroenterologist are in-network before starting the Duopa evaluation process.

Formulary Status & Step Therapy Rules

Duopa requires step therapy completion before Aetna will consider coverage. According to Aetna's clinical policy, you must document inadequate response or intolerable side effects with:

  1. Oral carbidopa-levodopa (required foundation therapy)
  2. Plus at least one of:
    • COMT inhibitor (entacapone, tolcapone)
    • Dopamine agonist (pramipexole, ropinirole)
    • MAO-B inhibitor (selegiline, rasagiline)

Medical Necessity Criteria

Duopa is only approved for members with advanced Parkinson's disease who are:

  • Levodopa responsive with well-defined "on" periods
  • Experiencing "off" periods totaling at least 3 hours per day despite optimized oral therapy
  • Appropriate surgical candidates for PEG-J tube placement

Prior Authorization Process

Step-by-Step: Fastest Path to Approval

1. Gather Documentation (Patient + Clinic)

  • Insurance card and member ID
  • Complete medication trial history with dates, doses, and reasons for discontinuation
  • Clinical notes documenting motor fluctuations and "off" time duration
  • Labs and imaging supporting Parkinson's diagnosis

2. Complete Prior Authorization Form (Prescriber)

  • Download Aetna's Medical Exception form
  • Include detailed clinical rationale for Duopa necessity
  • Document specific oral medication failures and adverse effects

3. Submit Request (Prescriber)

  • Online: Availity portal (fastest processing)
  • Fax: 877-269-9916
  • Phone: 855-240-0535
  • Timeline: Standard decisions within 30-45 days; expedited within 24 hours if urgent

4. Coordinate with Specialty Pharmacy (If Approved)

  • CVS Specialty typically handles Duopa distribution
  • Arrange home health training for pump operation
  • Schedule PEG-J tube placement with in-network gastroenterologist

Clinician Corner: Medical Necessity Letter Checklist

Your prescriber should include these elements in the prior authorization:

  • Diagnosis: Advanced Parkinson's disease with ICD-10 code G20
  • Current problem: Specific motor fluctuations, "off" time duration, impact on daily activities
  • Prior treatments: Complete list of oral medications tried, doses, duration, and reasons for failure/discontinuation
  • Clinical rationale: Why continuous intestinal infusion is medically necessary vs. other options
  • Treatment goals: Expected improvement in motor fluctuations and quality of life
  • Monitoring plan: How response will be assessed and adjusted

Specialty Pharmacy Setup

Once approved, Duopa must be dispensed through an Aetna-approved specialty pharmacy, typically CVS Specialty. The setup process involves:

Patient Responsibilities:

  • Complete specialty pharmacy enrollment forms
  • Coordinate delivery schedule (typically 30-day supplies)
  • Arrange home health training for pump operation and cassette changes

Clinical Coordination:

  • Prescriber submits prescription with specific dosing parameters
  • Gastroenterologist schedules PEG-J tube placement
  • Home health agency provides device training and ongoing support
Note: Duopa is billed under HCPCS code J7340, with 1 unit = one 100-mL cassette. Typical daily use requires one cassette, resulting in monthly costs around $7,000 at wholesale acquisition cost.

From Our Advocates

We've seen many Duopa approvals succeed when families work closely with their movement disorder specialist to document the specific impact of "off" periods on daily activities. One composite case involved a patient whose oral medications weren't controlling afternoon motor fluctuations, affecting their ability to work. The detailed activity diary showing specific times and functional limitations helped demonstrate medical necessity beyond just medication trial documentation.
