1 hospital

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

$22,047

Medicare paid this office $22,047 for 97 people.

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

Who their Medicare patients are

97 Original Medicare patients in 2024. Average age 70 · Under 65 24% · 85 and older 12% · Women 45% · Also on Medicaid 36% · Health risk score 2.81. Above the middle of the specialty; the typical internal medicine clinician is at 1.76.

Conditions among them: High blood pressure 75% · Coronary heart disease 42% · Chronic kidney disease 39% · Diabetes 36% · Heart failure 35% · Atrial fibrillation 32% · Depression 25% · COPD 19% · Dementia 19% · Cancer 18% · Stroke 16%.

The office billed $100,530, Medicare allowed $28,521 and paid $22,047; for 186 services of 17 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.

$2,388 in 2024

Medicaid paid $2,388 for 22 billed services this clinician did in 2024, 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.

$14,993

Pharmacies billed $14,993 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 21) in 2024. Too few prescriptions to compare fairly with other clinicians.

0 generic and 12 brand-name prescriptions · $14,993 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.

$287 in 2024

Paid work is consulting, speaking, honoraria and royalties, as opposed to meals and travel.

A payment is not proof that care is biased.

Research money

Money a company paid to run a study. Where it went to their institution, the clinician is named as an investigator and did not receive it; the amount covers the whole study, often across many sites.
