| Plan by plan | Plans |
|---|---|
| Same plan ID in both years | 22 |
| Listed it in 2026, not in 2027 | 0 (0%) |

| Added step therapy | 0 (0%) |
| Added a quantity limit | 0 (0%) |
| Added at least one of the three | 0 (0%) |
| Removed at least one of the three | 0 (0%) |
| Plan IDs new in 2027 | 4 |
| 2026 plan IDs not in the 2027 file | 13 |
The CMS summary has no count of tier moves down, so "Moved it to a lower tier" is counted from the plan rows on this page: plans with the same plan ID in both years that list potassium chloride both years.
Same plan ID in both years (22) plus 2026 plan IDs not in the 2027 file (13) add up to 35, not the 33 plans offered in North Dakota in 2026, because some plans are offered in different states in 2026 and 2027. 2 plan IDs counted in both years were offered only in other states in 2026.

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.
