20 measures · 2023

$650,155

Medicare paid this office $650,155 for 1,062 people.

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

Procedures Medicare counted

Who their Medicare patients are

1,062 Original Medicare patients in 2024. Average age 78 · Under 65 2% · 85 and older 25% · Women 50% · Also on Medicaid 7% · Health risk score 1.38. At or below the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Coronary heart disease 41% · Atrial fibrillation 36% · Diabetes 33% · Chronic kidney disease 26% · Heart failure 25% · Cancer 20% · Stroke 16% · COPD 15% · Depression 15% · Dementia 11%.

The office billed $1,558,716, Medicare allowed $847,037 and paid $650,155; for 9,629 services of 88 kinds; $31,333 of it was for drugs given in the office and $618,822 for care.

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.

$108 in 2024

Medicaid paid $108 for 48 billed services this clinician did in 2024, up to 24 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.

$1,542,555

Pharmacies billed $1,542,555 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 5,778) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

4,678 generic and 1,100 brand-name prescriptions · $1,542,555 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.
