$2,337

Medicare paid this office $2,337 for 13 people.

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

Procedures Medicare counted

Who their Medicare patients are

13 Original Medicare patients in 2024. Average age 63 · Health risk score 1.76. Above the middle of the specialty; the typical internal medicine clinician is at 1.76.

The office billed $16,808, Medicare allowed $3,871 and paid $2,337; for 17 services of 10 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.

$658 in 2024

Medicaid paid $658 for 28 billed services this clinician did in 2024, 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.

$301,036

Pharmacies billed $301,036 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 753) in 2024. At or below the middle of the specialty; the typical internal medicine clinician is at 1%.

606 generic and 147 brand-name prescriptions · $301,036 in drug cost · 29 antibiotic prescriptions.

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.
