Plan Types & Network Requirements

Aetna CVS Health offers multiple plan types in Ohio, each with different requirements for accessing Duopa:

HMO Plans: Require referrals to neurologists and movement disorder specialists. All prescriptions must be filled through in-network pharmacies. Prior authorization applies regardless of plan type.

PPO Plans: Allow direct access to specialists without referrals, but still require PA for Duopa. You can use out-of-network providers at higher cost-sharing, though specialty medications like Duopa typically require designated specialty pharmacies.

EPO Plans: Similar to PPOs but restrict coverage to in-network providers only. No referrals needed for specialists, but PA requirements remain.

Note: All Aetna plans in Ohio require specialty pharmacy dispensing for Duopa, regardless of plan type. Contact Aetna member services at 1-888-632-3862 to confirm your specific plan's requirements.

Formulary Status & Tier Placement

Duopa is classified as a Tier 5 (Specialty) medication on most Aetna formularies. This placement reflects its high cost (approximately $7,000 per month at wholesale acquisition cost) and complex administration requirements.
