For the analysis, researchers used data from the Medicare Plan Finder website last November and December to examine annual 2019 out-of-pocket costs for 30 specialty-tier drugs for cancer, hepatitis C, multiple sclerosis and rheumatoid arthritis. They looked at Medicare Part D plans that cover the drug, based on coverage in stand-alone prescription drug plans and costs at a pharmacy in ZIP code 21201 in Baltimore, Md.
That ZIP code approximates prescription drug plan costs nationally because 24 of the 25 Medicare Part D prescription drug plans in that ZIP code are offered nationally or near nationally. Researchers said prescription drug plans also typically use the same formulary and the same specialty-tier coinsurance rate nationally, making the analysis applicable to a majority of U.S. Medicare Part D prescription drug plan enrollees.
While researchers looked at 30 specialty-tier drugs, two of them, Gleevec and Viekira Pak, are not covered by any plan in 2019.
