What this clinician told their state board, medical school and everything before it. Only some states publish this, so nothing here means the state does not say, not that there was no training or certification.

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

$4,859

Medicare paid this office $4,859 for 51 people.

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

Who their Medicare patients are

51 Original Medicare patients in 2024. Average age 73 · Women 69% · Also on Medicaid 47% · Health risk score 1.45. At or below the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Diabetes 43% · Chronic kidney disease 25%.

The office billed $13,855, Medicare allowed $6,123 and paid $4,859; for 56 services of 8 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.

$185,141 in 2023

Medicaid paid $185,141 for 2,741 billed services this clinician did in 2023, up to 73 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.

$113,743

Pharmacies billed $113,743 in 2024.

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

Opioids were 6% of their Part D prescriptions (67 of 1,081) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%. Long-acting opioids: 24% of their opioid prescriptions.

932 generic and 135 brand-name prescriptions · $113,743 in drug cost · 17 antibiotic prescriptions to 14 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.
