$1,052,168

Medicare paid this office $1,052,168 for 1,475 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

1,475 Original Medicare patients in 2024. Average age 76 · Under 65 5% · 85 and older 16% · Women 63% · Also on Medicaid 31% · Health risk score 1.26. Above the middle of the specialty; the typical ophthalmology clinician is at 1.16.

Conditions among them: High blood pressure 75% · Diabetes 42% · Chronic kidney disease 28% · Coronary heart disease 26% · Heart failure 18% · Cancer 14% · Depression 14% · Atrial fibrillation 13% · COPD 10% · Stroke 8% · Dementia 6%.

The office billed $4,405,715, Medicare allowed $1,392,111 and paid $1,052,168; for 18,812 services of 49 kinds.

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.

$58,154 in 2024

Medicaid paid $58,154 for 2,415 billed services this clinician did in 2024, up to 70 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.

$341,542

Pharmacies billed $341,542 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 3,513) in 2024. At or below the middle of the specialty; the typical ophthalmology clinician is at 0%.

2,205 generic and 1,308 brand-name prescriptions · $341,542 in drug cost · 15 antibiotic prescriptions to 11 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.

$4,358 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.

Medicare did not publish checkup rates for this clinician.
