Renewal and Reauthorization

Good news: As of July 2024, Cigna eliminated annual reauthorization requirements for Duopa. Once approved, coverage continues without yearly renewal paperwork.

However, coverage may still be reviewed if:

  • Your plan changes formularies
  • New step therapy requirements are added
  • Clinical circumstances change significantly

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn
Insufficient "off" episode documentation Provide detailed diary showing ≥3 hours daily "off" time
Missing extended-release carbidopa/levodopa trial Submit pharmacy records and clinic notes documenting inadequate response
Fewer than three additional therapy failures Document trials of entacapone, rasagiline, pramipexole, or other approved alternatives
Non-specialist prescriber Obtain consultation or prescription from movement disorder neurologist
Incomplete prior authorization form Resubmit with all sections completed and signed
Medical necessity not established Provide detailed functional assessment and quality of life impact
From our advocates: We've seen many Duopa denials overturned by providing a comprehensive "off" episode diary that quantifies motor fluctuations throughout the day. Patients who document specific times, symptoms, and functional limitations have much stronger cases for medical necessity.
