$217,583

Medicare paid this office $217,583 for 605 people.

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

Who their Medicare patients are

605 Original Medicare patients in 2024. Average age 75 · Under 65 11% · 85 and older 19% · Women 50% · Also on Medicaid 57% · Health risk score 2.90. At or below the middle of the specialty; the typical nephrology clinician is at 4.01.

Conditions among them: High blood pressure 75% · Chronic kidney disease 75% · Diabetes 61% · Heart failure 34% · Coronary heart disease 33% · Atrial fibrillation 26% · Depression 25% · COPD 23% · Cancer 14% · Stroke 14% · Dementia 13%.

The office billed $684,724, Medicare allowed $301,610 and paid $217,583; for 2,029 services of 27 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.

$35,053 in 2024

Medicaid paid $35,053 for 777 billed services this clinician did in 2024, up to 36 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.

$1,118,699

Pharmacies billed $1,118,699 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 2,050) in 2024. At or below the middle of the specialty; the typical nephrology clinician is at 0%.

1,221 generic and fewer than 11 brand-name prescriptions · $1,118,699 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.

$397 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.
