Every 2027 plan in Mississippi
Each Part D plan offered in Mississippi, with Gattex's 2026 and 2027 tier and its 2027 limits. A tier is the cost level a plan puts a drug on; a lower tier usually costs less. Enter a ZIP to see only the plans offered in that county.
PA is prior authorization (the plan must approve it first), ST is step therapy (try another drug first), and QL is a quantity limit. D-SNP, C-SNP, and I-SNP are Special Needs Plans: for people with both Medicare and Medicaid, with certain chronic conditions, or who live in a nursing home or need that level of care.

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.
