These rate the hospital, not this clinician. Most measures at most hospitals are no different from the national rate.

$54,089

Medicare paid this office $54,089 for 446 people.

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

Procedures Medicare counted

Who their Medicare patients are

446 Original Medicare patients in 2024. Average age 74 · Under 65 9% · 85 and older 10% · Women 63% · Also on Medicaid 19% · Health risk score 1.24. At or below the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 59% · Diabetes 26% · Coronary heart disease 22% · Cancer 20% · Chronic kidney disease 18% · Atrial fibrillation 16% · Depression 15% · Heart failure 12% · COPD 8% · Dementia 6% · Stroke 5%.

The office billed $401,381, Medicare allowed $88,861 and paid $54,089; for 961 services of 15 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.

$1,038 in 2024

Medicaid paid $1,038 for 57 billed services this clinician did in 2024, up to 19 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.

$408,389

Pharmacies billed $408,389 in 2024.

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

Opioids were 3% of their Part D prescriptions (118 of 4,090) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

3,630 generic and 443 brand-name prescriptions · $408,389 in drug cost · 78 antibiotic prescriptions to 52 people · 12 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.
