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

$16,048

Medicare paid this office $16,048 for 113 people.

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

Who their Medicare patients are

113 Original Medicare patients in 2024. Average age 77 · Women 53% · Also on Medicaid 60% · Health risk score 2.58. 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 58% · Heart failure 51% · Diabetes 48% · Coronary heart disease 38% · Depression 36% · Atrial fibrillation 35% · COPD 34% · Dementia 26% · Stroke 24% · Cancer 19%.

The office billed $80,056, Medicare allowed $22,019 and paid $16,048; for 115 services of 2 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.

$3,691 in 2018

Medicaid paid $3,691 for 12 billed services this clinician did in 2018, up to 12 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.

$437,249

Pharmacies billed $437,249 in 2024.

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

Opioids were 2% of their Part D prescriptions (13 of 588) in 2024. Above the middle of the specialty; the typical internal medicine clinician is at 1%.

446 generic and 142 brand-name prescriptions · $437,249 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.
