Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 13 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. AbbVie accounts for 72.3% of it on its own, with 4 other manufacturers making up the rest. That places this record below the midpoint for physical medicine & rehabilitation clinicians in IN, where the typical reported total is $403.
Across 13 payments — averaging $15.58 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| Gabapentin | 67 | $1,068 |
| Lamotrigine | 25 | $589 |
| Metoclopramide Hcl | 13 | $96 |
Paid to pharmacies, not to this prescriber.
