$111,675

Medicare paid this office $111,675 for 376 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

376 Original Medicare patients in 2024. Average age 74 · Under 65 5% · 85 and older 6% · Women 55% · Also on Medicaid 9% · Health risk score 0.87. At or below the middle of the specialty; the typical orthopedic surgery clinician is at 1.13.

Conditions among them: High blood pressure 67% · Coronary heart disease 23% · Depression 18% · Diabetes 16% · Chronic kidney disease 13% · Atrial fibrillation 13% · Cancer 12% · COPD 11% · Heart failure 7% · Stroke 3%.

The office billed $453,933, Medicare allowed $150,065 and paid $111,675; for 944 services of 26 kinds; $95 of it was for drugs given in the office and $111,580 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.

$1,524 in 2023

Medicaid paid $1,524 for 13 billed services this clinician did in 2023, up to 12 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

$3,753

Pharmacies billed $3,753 in 2024.

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

Opioids were 41% of their Part D prescriptions (188 of 461) in 2024. Above the middle of the specialty; the typical orthopedic surgery clinician is at 31%. Surgeons prescribe little besides pain medicine after an operation, so their opioid share runs high.

459 generic and fewer than 11 brand-name prescriptions · $3,753 in drug cost · 11 antibiotic prescriptions.

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.

$345 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.

9 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.

What the office says it does

Boxes the office ticked on its Medicare worksheet for 2023. Nobody checks these.

• Implementation of medication management practice improvements
• Improved the patient portal
• Lets patients read their visit notes
• Uses standard treatment protocols
