$601,323

Medicare paid this office $601,323 for 1,120 people.

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

Procedures Medicare counted

Who their Medicare patients are

1,120 Original Medicare patients in 2024. Average age 76 · Under 65 2% · 85 and older 13% · Women 66% · Also on Medicaid 12% · Health risk score 1.01. At or below the middle of the specialty; the typical ophthalmology clinician is at 1.16.

Conditions among them: High blood pressure 66% · Coronary heart disease 22% · Diabetes 21% · Chronic kidney disease 18% · Depression 18% · Atrial fibrillation 16% · Cancer 15% · COPD 10% · Heart failure 9% · Stroke 6% · Dementia 3%.

The office billed $1,490,771, Medicare allowed $765,583 and paid $601,323; for 12,842 services of 56 kinds; $49,558 of it was for drugs given in the office and $551,765 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.

$36,353

Pharmacies billed $36,353 in 2024.

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

908 generic and 114 brand-name prescriptions · $36,353 in drug cost · 107 antibiotic prescriptions to 81 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.

$416 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.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.

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.
