stand-alone prescription drug plan
What is a stand-alone prescription drug plan?
A stand-alone prescription drug plan is another term for a Part D prescription drug plan (PDP).
A PDP is often referred to as a “stand-alone prescription drug plan” because it is separate prescription drug coverage that Medicare beneficiaries can purchase – through private insurers – usually to supplement Original Medicare.
Most Medicare Advantage plans include Part D benefits and that type of coverage is know as a Medicare Advantage prescription drug plan (MAPD).
As of 2019, about 46 percent of Part D enrollees were enrolled in a PDP while another 39 percent had an MAPD.
