$311,397

Medicare paid this office $311,397 for 611 people.

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

Who their Medicare patients are

611 Original Medicare patients in 2024. Average age 76 · Under 65 10% · 85 and older 23% · Women 48% · Also on Medicaid 73% · Health risk score 3.75. 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 65% · Heart failure 50% · Coronary heart disease 42% · Atrial fibrillation 37% · COPD 25% · Depression 22% · Dementia 20% · Stroke 19% · Cancer 16%.

The office billed $856,966, Medicare allowed $417,508 and paid $311,397; for 2,812 services of 26 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.

$41,375 in 2024

Medicaid paid $41,375 for 967 billed services this clinician did in 2024, up to 49 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.

$1,105,346

Pharmacies billed $1,105,346 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 3,022) in 2024. At or below the middle of the specialty; the typical nephrology clinician is at 0%.

1,904 generic and 1,095 brand-name prescriptions · $1,105,346 in drug cost · 47 antibiotic prescriptions to 22 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.
