$307,531

Medicare paid this office $307,531 for 508 people.

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

Who their Medicare patients are

508 Original Medicare patients in 2024. Average age 77 · Under 65 5% · 85 and older 23% · Women 42% · Also on Medicaid 13% · Health risk score 2.69. Above the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Chronic kidney disease 75% · Diabetes 50% · Coronary heart disease 41% · Heart failure 32% · Atrial fibrillation 31% · Cancer 19% · Dementia 15% · Stroke 14% · COPD 13% · Depression 13%.

The office billed $733,890, Medicare allowed $402,863 and paid $307,531; for 2,096 services of 19 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.

$0 in 2020

Medicaid paid $0 for 17 billed services this clinician did in 2020, up to 17 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.

$814,410

Pharmacies billed $814,410 in 2024.

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

Opioids were 2% of their Part D prescriptions (84 of 4,743) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

3,978 generic and 732 brand-name prescriptions · $814,410 in drug cost · 144 antibiotic prescriptions to 67 people · 15 antipsychotic prescriptions to people over 65.

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.
