Every 2027 stand-alone drug plan
Each stand-alone Part D plan (PDP) with Vemlidy's 2027 tier and limits. CMS files a PDP once per region, so one plan name can have several plan IDs; the row shows the tier and limits most of them use. Medicare Advantage drug plans are local: pick a state for its plan-by-plan table.

Near it by Part D spending
About this data
A plan here is one Part D plan as the CMS formulary files list it: contract, plan, and segment. That covers Medicare Advantage plans with drug coverage and stand-alone drug plans. A plan lists a drug when its formulary has a row for any RxNorm product of that name. When it has several, the row with the lowest tier is the one counted, and restricted means that row has prior authorization, step therapy, or a quantity limit.
A plan with no row for the drug counts as not listing it. That can be a product the file codes another way, so read a low count as a lookup result, not a coverage decision. A state counts every plan the CMS landscape file offers there. Parent organizations are named as CMS names them. The drug list is the top 200 by total Part D spending.
