$334,759

Medicare paid this office $334,759 for 602 people.

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

Procedures Medicare counted

Who their Medicare patients are

602 Original Medicare patients in 2024. Average age 74 · Under 65 2% · 85 and older 5% · Women 63% · Also on Medicaid 7% · Health risk score 0.84. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 1.13.

Conditions among them: High blood pressure 68% · Chronic kidney disease 22% · Coronary heart disease 19% · Cancer 17% · Diabetes 16% · Atrial fibrillation 14% · Depression 14% · Heart failure 8% · COPD 8% · Stroke 5% · Dementia 2%.

The office billed $2,669,174, Medicare allowed $429,379 and paid $334,759; for 1,740 services of 28 kinds; $1,063 of it was for drugs given in the office and $333,696 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.

$1,735

Pharmacies billed $1,735 in 2024.

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

Opioids were 28% of their Part D prescriptions (22 of 78) in 2024. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 31%.

75 generic and fewer than 11 brand-name prescriptions · $1,735 in drug cost · 14 antibiotic prescriptions to 14 people.

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.

$20,954 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.

1 measures · 2023

Medicare asked this office to report how often certain checkups happened in 2023. This is not a grade for the doctor. A specialist’s patients may not need every screening.
