General payments per clinician in Wisconsin across program years
Drug and device makers paid Wisconsin’s clinicians $4,167 each in 2025, against $2,813 across the country
General payments reported to CMS for clinicians in Wisconsin, divided by the clinicians they were reported for, by program year, against the same across the country.
The clinicians counted are the ones paid, not every clinician practising, so this is what a paid clinician received on average, not what a clinician did.
2025 is published and still being revised, so its last point may move.
A clinician is counted in the state CMS lists for them that year, so one who moved is counted where they were paid.

What Wisconsin’s doctors prescribed under Medicare
A second CMS file records what doctors prescribed rather than what they were paid. In 2024, 26,027 prescribers with a Wisconsin address filled 31,645,750 Medicare Part D prescriptions costing $4,883,899,094 — 1.7% of the $288.4 billion Medicare paid nationally. None of that money went to the doctors. It is what Medicare, its plans and patients paid pharmacies for what they wrote.
- 31,645,750
- Prescriptions filled
- Claims, counting every refill. 2024 only, not the period above.
- $4.9 billion
- What the drugs cost
- $4,883,899,094
- Paid to pharmacies by Medicare, its plans and patients. Not income for any doctor.
- 1.7%
- Share of the national drug cost
- Of $288.4 billion Medicare paid nationally in 2024.
- 26,027
- Prescribers
- People CMS published a Part D row for. CMS drops a prescriber-drug row under eleven claims, so a doctor who prescribed little of everything is not here — and this is not a count of doctors in Wisconsin.
- 1,005,695
- Opioid prescriptions
- Of 59,133,014 nationally. CMS withheld the opioid count from 350,416 prescribers, so this is a floor rather than a total.
The state is the practice address CMS holds for the prescriber, not where the patient lives or the pharmacy stands. Unlike the payment figures above, every Part D claim is attributed to a state, so these rows do add up to the national total — the gap described further down this page is an Open Payments gap and not this one. Prescribers ranked by claims, by what their prescriptions cost and by opioid claims are national lists.
Wisconsin elsewhere on the Factbook
- Reported crime Crime and justice
Offenses reported to police by type, the trend, and the reporting coverage.
- Most dangerous cities in Wisconsin Crime and justice
What each agency serving 25,000 or more reported, ranked. Agency populations overlap, so these do not add up to the state.
- Prison population Crime and justice
People held under the state’s correctional authority, and the imprisonment rate. A different publisher counting a different thing.
- Arrests by race, sex and age Crime and justice
Arrests as the FBI’s participating agencies reported them, with what the figures can and cannot support at the top.
- Hate crime Crime and justice
Incidents reported to the FBI by bias motivation, as counts — the collection publishes no participation share, so there is no rate to compare states on.
- Federal obligations Federal spending
What federal agencies obligated against a place of performance in the state, per resident and by agency.
- Registered nonprofits Nonprofits
How many organizations the IRS lists in the state, what they report as revenue, and which kinds of work they do.
- Farm program payments Farm subsidies
What the Farm Service Agency paid through the state’s county offices, by program and by recipient. The offices that administered the payments, not a count of farms: a recipient addressed elsewhere is counted where they were paid.
- Paycheck Protection Program loans PPP loans
The PPP loans SBA guaranteed to businesses operating in the state, by county, with how many carry a forgiveness amount and how many were charged off. Loans, not businesses: a business with two draws is two loans.
- Population, age, income and origin Demographics
The Census Bureau's population estimates year by year, with births, deaths and migration, and age, income, poverty, housing and origin from the American Community Survey, each with its margin of error.
- Public schools Schools
Pupils, schools and teachers, the largest districts, what districts spend per pupil and where the money comes from, and the colleges that take federal student aid.
- Banks and credit unions Banks and credit unions
The FDIC-insured banks headquartered in the state and their offices, and the credit unions based there and their sites, each per resident and against every other state.
- Housing Housing
The homes under HUD’s rental assistance programs in the state, by program and county, and its tax-credit housing, each per resident and against every other state.
- Mortgage lending Mortgage lending
The mortgage applications, loans and denials lenders reported in the state under the Home Mortgage Disclosure Act, and its largest lenders and counties.
- Cost of living Cost of living
BEA’s price level for the state against the nation, for goods, rents, utilities and other services, and its metro areas beside it.

CDC’s model-based estimates of adult health, risk behaviors and prevention for every county in the state, each with its 95% interval.
- College athletics Sports
Every college in the state that reported to the Equity in Athletics survey, ranked by its athletics revenue, with its expenses, athletes and athletic aid.
- Federal civilian workforce Federal salaries
Federal civilian employees stationed in the state by agency and occupation, with the pay OPM publishes and the share it withholds.
- The Wisconsin Factbook entry Across the Factbook
Every measure the Factbook publishes for this state in one place, each with where it ranks among the others and the record it came from.
The immigration hub has no page for this state: EOIR runs no immigration court here, and CBP publishes by sector and field office, which are its own areas of responsibility rather than a geography. Immigration and the border.
What this page does not show
- Where the work happened. The state is the practice address CMS holds for the doctor, not the place the payment was earned or the patient was seen.
- Doctors CMS holds no state for. 435 of 1,693,971 profiles carry no state, holding $3,697,188 in general payments. They are in the national total and on no state page, which is why the 51 state pages do not sum to it.
- Anything about influence. The record says what was paid and by whom, and this page makes no claim beyond that.
