$79,951

Medicare paid this office $79,951 for 297 people.

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

Who their Medicare patients are

297 Original Medicare patients in 2024. Average age 75 · Under 65 5% · 85 and older 11% · Women 63% · Also on Medicaid 21% · Health risk score 1.03. At or below the middle of the specialty; the typical family practice clinician is at 1.13.

Conditions among them: High blood pressure 60% · Depression 21% · Diabetes 19% · Chronic kidney disease 18% · Cancer 16% · Coronary heart disease 12% · Atrial fibrillation 10% · Heart failure 9% · COPD 8% · Dementia 6% · Stroke 4%.

The office billed $255,662, Medicare allowed $100,308 and paid $79,951; for 962 services of 46 kinds; $12,412 of it was for drugs given in the office and $67,539 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.

$1,781 in 2022

Medicaid paid $1,781 for 39 billed services this clinician did in 2022, up to 14 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.

$117,364

Pharmacies billed $117,364 in 2024.

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

Opioids were 18% of their Part D prescriptions (210 of 1,177) in 2024. A higher opioid share than 9 in 10 peers; the typical family practice clinician is at 2%. Long-acting opioids: 14% of their opioid prescriptions.

1,056 generic and fewer than 11 brand-name prescriptions · $117,364 in drug cost · 39 antibiotic prescriptions to 35 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.

$157 in 2022

A payment is not proof that care is biased.
