Medical Necessity Requirements

Aetna CVS Health follows Medicare criteria for Duopa coverage, requiring documentation of advanced Parkinson's disease with motor fluctuations that haven't responded to optimized oral therapy.

Core Clinical Criteria

Diagnosis Requirements:

  • Advanced Parkinson's disease with disabling motor fluctuations
  • At least 3 hours daily of "off" time despite optimized therapy
  • Levodopa-responsive symptoms
  • Appropriate surgical candidate for PEG-J tube placement

Documentation Needed:

  • ICD-10 codes for Parkinson's disease
  • Objective measurement of "off" time (patient diaries, clinic notes)
  • Movement disorder specialist evaluation
  • Pre-surgical clearance for PEG-J procedure
Tip: Use standardized "off" time diaries for at least one week before submitting your PA request. This objective documentation strengthens your case significantly.

Step Therapy and Documentation

Aetna CVS Health enforces step therapy, meaning you must demonstrate failure or intolerance to oral medications before Duopa approval.

Required Failed Therapies

Primary Requirements:

  1. Optimized oral carbidopa/levodopa - Maximum tolerated doses, typically 5+ times daily
  2. Adjunct medications - At least one of:
    • MAO-B inhibitors (rasagiline, selegiline)
    • COMT inhibitors (entacapone, tolcapone)
    • Dopamine agonists (if not contraindicated)
    • Amantadine

Documentation Checklist for Failed Oral Therapy

  • Medication history with doses, duration, and response
  • Reasons for failure - lack of efficacy, intolerable side effects, contraindications
  • Current symptoms - specific examples of motor fluctuations
  • Functional impairment - impact on activities of daily living

Sample Documentation Language: "Patient has failed optimized oral carbidopa/levodopa 25/100 mg five times daily plus rasagiline 1 mg daily due to persistent disabling motor fluctuations with 4+ hours daily 'off' time. Dopamine agonist contraindicated due to history of impulse control disorder. Patient experiences unpredictable freezing episodes and requires assistance with ADLs during 'off' periods."

Prior Authorization Process

    • Timeline: Submit 2 weeks before planned start

    • Expedited review: 72 hours with physician urgency statement
    • Follow up if no response within timeline
  4. Coordinate Specialty Pharmacy (Upon Approval)
    • CVS Specialty will contact patient
    • Schedule pump training and delivery

Common Denial Reasons and Fixes

Denial Reason How to Overturn Required Documentation
Insufficient trial of oral therapy Provide detailed medication history Complete list with doses, duration, outcomes
Lack of motor fluctuation documentation Submit objective "off" time data Patient diaries, clinic assessments
Missing surgical clearance Obtain pre-procedural evaluation Gastroenterology or surgery consultation
Coding errors Correct billing submission Use J7340, proper unit calculation
Non-formulary status Request formulary exception Clinical justification letter

Medical Necessity Letter Template

Your prescriber should include these elements:

Problem Statement: "Patient has advanced Parkinson's disease with disabling motor fluctuations despite optimized oral therapy..."

Prior Treatments: "Failed trials include: [list medications with doses, duration, reasons for failure]..."

Clinical Rationale: "Duopa is medically necessary because continuous intestinal infusion provides stable drug levels, reducing motor fluctuations..."
