Medicaid use by state
CMS's State Drug Utilization Data records, for 2025, how many prescriptions each state's Medicaid program paid for under this drug's packages and what it reimbursed. The 1 states with the largest reimbursement are shown. Reimbursement is before the rebates manufacturers pay states, so it is not a net cost and not a price a patient pays.
| State | Medicaid-paid prescriptions | Medicaid reimbursed | Covers |
|---|---|---|---|
| OK | 237 | $110,662 | Fee-for-service only |
Where the publisher suppresses small managed-care cells, a state's figure covers fee-for-service claims only and understates use (1 state and package figure is marked that way here). A state missing from the table means its figures were suppressed or not reported, not zero use. 45 older-year figures are held and left out of the table.
