How this compares
Too few colon & rectal surgery providers in New Hampshireto place this figure against a meaningful peer group, so we don't.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Sod Sulf-Potass Sulf-Mag SulfSodium, Potassium,mag Sulfates | 25 | $1,596 |
| Hydrocortisone | 15 | $245 |
| Neomycin Sulfate | 16 | $80 |
| Ondansetron Hcl | 38 | $76 |
| Metronidazole | 17 | $39 |
