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

$12,691,262

Medicare paid this office $12,691,262 for 2,078 people.

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

Procedures Medicare counted

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

2,078 Original Medicare patients in 2024. Average age 73 · Under 65 18% · 85 and older 19% · Women 49% · Also on Medicaid 69% · Health risk score 2.14. Sicker patients than 9 in 10 peers; the typical family practice clinician is at 1.13.

Conditions among them: High blood pressure 75% · Depression 44% · Diabetes 42% · Chronic kidney disease 35% · Dementia 35% · Heart failure 32% · Coronary heart disease 31% · COPD 25% · Atrial fibrillation 24% · Stroke 19% · Cancer 11%.

The office billed $16,950,598, Medicare allowed $15,964,717 and paid $12,691,262; for 17,808 services of 57 kinds; $9,839,104 of it was for drugs given in the office and $2,852,158 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.

$339,096 in 2024

Medicaid paid $339,096 for 3,846 billed services this clinician did in 2024, up to 180 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.

$618,548

Pharmacies billed $618,548 in 2024.

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

Opioids were 2% of their Part D prescriptions (174 of 7,893) in 2024. Above the middle of the specialty; the typical family practice clinician is at 2%. Long-acting opioids: 21% of their opioid prescriptions.

6,552 generic and 1,300 brand-name prescriptions · $618,548 in drug cost · 240 antibiotic prescriptions to 101 people · 191 antipsychotic prescriptions to people over 65.

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.

$43 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.
