$3,706

Medicare paid this office $3,706 for 15 people. Most of that is long return visits and Botox.

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

Who their Medicare patients are

15 Original Medicare patients in 2024. Average age 56 · 85 and older 0% · Health risk score 1.86. Above the middle of the specialty; the typical pediatric medicine clinician is at 1.4.

The office billed $24,380, Medicare allowed $5,031 and paid $3,706; for 66 services of 3 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.

$20,933 in 2024

Medicaid paid $20,933 for 202 billed services this clinician did in 2024, up to 22 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.

$1,590,399

Pharmacies billed $1,590,399 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 47) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

0 generic and 40 brand-name prescriptions · $1,590,399 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.

$9,587 in 2025

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.

Medicare did not publish checkup rates for this clinician.
