Top 25 of 561 MS-DRGs with published discharges in Wisconsin, ranked by discharges. Share is this state's discharges against the DRG's national total (both from CMS's by-geography inpatient file, so a share never exceeds 100%). Each DRG opens its market for Wisconsin. Discharges are counted stays under Medicare fee-for-service Part A (no Medicare Advantage), Maryland waiver-priced.

Ranked by claims: the 25 of 2,243 medications CMS publishes for Wisconsin with the most claims in CY2024. Medications are shown as CMS prints them, at the brand-and-generic grain CMS publishes. Geography is the prescriber's state as CMS files it: claims are counted where the prescriber sits, not where the pharmacy or the patient is. A claim is one dispensed fill, refills included; it is not a prescription written and not a patient count. 30-day fills restate claims to a 30-day supply, so a 90-day fill counts as three. Share is this state's claims against the total CMS publishes for the medication nationally. Claims are Medicare Part D drug-plan claims, Medicare Advantage plans included. Drug cost and prescriber figures are not part of this page.

Figures are attributable Medicare billing: each service is credited to a physician group only when the clinician who billed it belongs to exactly one group in CMS's Doctors and Clinicians register. Clinicians registered with more than one group, and groups without a specialty label, are not included in the specialty table above.

The physician-billing figures are Medicare fee-for-service Part B, and the hospital inpatient figures Medicare fee-for-service Part A — Medicare Advantage is not included in these. The Part D medication claims are the exception: they are drug-plan claims and include Medicare Advantage drug plans.
