Original Medicare doctor bills
$3,043
Medicare paid this office $3,043 for 20 people.
This is what Medicare paid the clinician — not Medicare Advantage, and not the pharmacy.
Procedures Medicare counted
| Colonoscopy | 1-10 | None |
| Upper gastrointestinal (GI) endoscopy for acid reflux | 1-10 | None |
Who their Medicare patients are
20 Original Medicare patients in 2024. Average age 63 · Health risk score 1.29. At or below the middle of the specialty; the typical gastroenterology clinician is at 1.42.
The office billed $14,322, Medicare allowed $3,820 and paid $3,043; for 20 services of 9 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
| 2024 | 20 | 20 | 63 | 1.29 | $14,322 | $3,043 |
| 2023 | 11 | 15 | 62 | 1.48 | $6,234 | $1,344 |
| 2022 | 15 | 1,529 | 67 | 1.29 | $133,481 | $29,444 |
| 2021 | 11 | 19 | 67 | 1.50 | $12,452 | $3,230 |
| 2018 | 12 | 15 | 66 | 2.38 | $13,767 | $2,584 |
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.
Medicaid work
$1,742 in 2024
Medicaid paid $1,742 for 28 billed services this clinician did in 2024, up to 15 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.
| Liver elastography, mechanically induced shear wave (eg, vibration), without imaging, with interpretation and report | 28 | $1,742 |
| 2024 | 28 | 1 | 15 | $1,742 |
Drugs they prescribed that Part D paid
$520,796
Pharmacies billed $520,796 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 619) in 2024. At or below the middle of the specialty; the typical gastroenterology clinician is at 0%.
514 generic and 105 brand-name prescriptions · $520,796 in drug cost · 47 antibiotic prescriptions to 11 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.
