$45,337

Medicare paid this office $45,337 for 202 people.

This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.

Procedures Medicare counted

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

202 Original Medicare patients in 2024. Average age 72 · Women 57% · Also on Medicaid 10% · Health risk score 0.89. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 1.13.

Conditions among them: High blood pressure 52% · Coronary heart disease 21% · Diabetes 14% · Cancer 13% · Atrial fibrillation 13% · Depression 12% · Chronic kidney disease 11% · Heart failure 9% · COPD 6%.

The office billed $205,692, Medicare allowed $61,265 and paid $45,337; for 5,816 services of 39 kinds; $6,860 of it was for drugs given in the office and $38,477 for care.

Original Medicare patients only. A risk score of 1.0 is the average Medicare patient; higher means sicker. Any count under 11 is hidden.

Year by year

Original Medicare only. A service billed for fewer than 11 people in a year is hidden, so the lines can add up to less than the year's total.

$322

Pharmacies billed $322 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

40 generic and fewer than 11 brand-name prescriptions · $322 in drug cost.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.

Year by year

Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.

$30 in 2025

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.

Medicare did not publish checkup rates for this clinician.
