$212,420

Medicare paid this office $212,420 for 165 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

165 Original Medicare patients in 2024. Average age 74 · Women 63% · Health risk score 0.81. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 1.13.

Conditions among them: High blood pressure 47% · Coronary heart disease 19% · Depression 19% · Cancer 15% · Atrial fibrillation 13% · Chronic kidney disease 12% · Diabetes 9%.

The office billed $575,914, Medicare allowed $274,031 and paid $212,420; for 4,805 services of 63 kinds; $104,946 of it was for drugs given in the office and $107,473 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.

$2,436

Pharmacies billed $2,436 in 2024.

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

Opioids were 44% of their Part D prescriptions (14 of 32) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

32 generic and 0 brand-name prescriptions · $2,436 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.

$64 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.
