Every 2027 plan in Illinois
Each Part D plan offered in Illinois, with Wegovy'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. Plans are listed by plan ID.

By dosage form
The 2027 formularies list Wegovy by dosage form. A plan can cover one form and leave off or restrict another, so each form is counted on its own.
| Dosage form | Plans that list it | Restricted (of listing) | Most common tier |
|---|---|---|---|
| Auto-injector | 133 (100%) | 133 (100%) | Tier 3 |
| Oral tablet | 133 (100%) | 133 (100%) | Tier 3 |
| Pen injector | 0 (0%) | none list it | none list it |
Illinois compared with the nation
100% of the 133 Part D plans offered in Illinois leave Wegovy off the 2027 formulary or restrict it, against 100% nationally (the same). All 51 states are at 100% of plans restricting or leaving it off, so Illinois is not ranked. A plan offered in several states counts in each.

| Plan IDs new in 2027 | 18 |
| 2026 plan IDs not in the 2027 file | 34 |
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 Wegovy both years.
Restricted listings rose from 0 to 133, but none of the 115 plans offered in both years added prior authorization, step therapy, or a quantity limit to Wegovy. The rise comes from plan IDs that are new in 2027: 18 new plan IDs, and 18 of them restrict it. 34 plan IDs from 2026 are not in the 2027 file.
Same plan ID in both years (115) plus 2026 plan IDs not in the 2027 file (34) add up to 149, not the 150 plans offered in Illinois in 2026, because some plans are offered in different states in 2026 and 2027. 3 plan IDs counted in both years were offered only in other states in 2026, and 4 plan IDs offered here in 2026 are offered only in other states in 2027, so they count in neither row.

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.
