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

$30,390

Medicare paid this office $30,390 for 146 people.

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

Procedures year by year

Times billed to Original Medicare each year. A blank year means fewer than 11 people had it, or none: Medicare does not publish smaller counts. Medicare Advantage patients are not included.

Who their Medicare patients are

146 Original Medicare patients in 2024. Average age 72 · Women 57% · Also on Medicaid 23% · Health risk score 1.19. Above the middle of the specialty; the typical sports medicine clinician is at 1.05.

Conditions among them: High blood pressure 59% · Depression 23% · Coronary heart disease 22% · Diabetes 20% · Cancer 18% · Atrial fibrillation 16% · Chronic kidney disease 15% · Heart failure 12% · COPD 10%.

The office billed $238,346, Medicare allowed $42,092 and paid $30,390; for 907 services of 33 kinds; $2,052 of it was for drugs given in the office and $28,338 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.

$1,244 in 2024

Medicaid paid $1,244 for 12 billed services this clinician did in 2024, 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.

$682

Pharmacies billed $682 in 2024.

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

Opioids were 46% of their Part D prescriptions (12 of 26) in 2024. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.

26 generic and 0 brand-name prescriptions · $682 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.

$36 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.

Medicare did not publish checkup rates for this clinician.
