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

| Colonoscopy | 12 | More than 42% of doctors who do this |
Year by year
| 2018 | 25 | 32 | 65 | 3.09 | $31,115 | $6,784 |

| 2016 | 73 | 99 | 68 | 1.82 | $84,047 | $17,105 |
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.

Drugs they prescribed that Part D paid
$650
Pharmacies billed $650 in 2024.
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 41% of their Part D prescriptions (31 of 76) in 2024. A higher opioid share than 9 in 10 peers; the typical colorectal surgery (proctology) clinician is at 16%.
76 generic and 0 brand-name prescriptions · $650 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.
| Ibuprofen | 25 | $236 | $9 |
| Oxycodone | 16 | $107 | $7 |
| Tramadol | 14 | $92 | $6 |
