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

404 Original Medicare patients in 2024. Average age 75 · Under 65 4% · 85 and older 12% · Women 57% · Also on Medicaid 19% · Health risk score 1.19. Above the middle of the specialty; the typical ophthalmology clinician is at 1.16.

Conditions among them: High blood pressure 73% · Diabetes 31% · Coronary heart disease 22% · Chronic kidney disease 22% · Depression 17% · Cancer 15% · Atrial fibrillation 14% · Heart failure 11% · COPD 10% · Stroke 7% · Dementia 3%.

The office billed $542,286, Medicare allowed $206,237 and paid $162,266; for 1,846 services of 44 kinds; $49,680 of it was for drugs given in the office and $112,586 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.

$14,074 in 2024

Medicaid paid $14,074 for 346 billed services this clinician did in 2024, up to 42 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.

$20,336

Pharmacies billed $20,336 in 2024.

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

Opioids were 0% of their Part D prescriptions (0 of 190) in 2024. At or below the middle of the specialty; the typical ophthalmology clinician is at 0%.

97 generic and 93 brand-name prescriptions · $20,336 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.

$6,637 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.
