Health insurer Aetna and CVS/pharmacy announced Wednesday that they are launching a new co-branded Medicare Part D prescription drug plan.

The plan will be available in 43 states and Washington D.C.

Medicare beneficiaries will be offered a $26 monthly plan premium that has no deductible for generic drugs.

Medicare beneficiaries signing up for the plan and fill their prescriptions at CVS/pharmacy will save on their out-of-pocket prescription drug costs.

Members of the plan will pay a $3 copayment for preferred generic prescriptions

They will also save $10 on copayments for non-referred generic and preferred brand prescriptions.

The program “increases our members’ access” to the CVS pharmacy chain, said John Chomeau, head of Aetna Medicare.

He said there would be more “convenient access” for Medicare beneficiaries to access the prescription drugs they need, noting a CVS/pharmacy is within 3 miles of 75 percent of the U.S. population.

CVS/Pharmacy senior VP of retail pharmacy Josh Flum said the plan allows plan members to “build a relationship with their CVS pharmacist along with the opportunity to realize savings on their prescriptions.”
