Average annual deductibles in independent prescription drug plans (PDPs) are roughly four times higher than those in Medicare Advantage plans (MA-PDs) ($398 versus $90). Average monthly premiums for PDPs are also roughly 3.5 times higher than in MA-PDPs ($40 versus $11). Similarly, MA-PDP formularies cover a higher share of potentially coverable Part D drugs than PDPs (89 percent compared to 83 percent). At the same time, MA-PDPs impose utilization management requirements (such as prior authorization and quantity limits) on formulary covered drugs at a lower rate, relative to PDPs.
