Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (56.4%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. Boehringer Ingelheim accounts for 62.8% of it on its own, with 3 other manufacturers making up the rest. 2025 is the largest year on record at $31,877, more than ten times the $2,206 reported in 2019. Among internal medicine clinicians in NC with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 121 payments — averaging $472.79 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Boehringer Ingelheim$36K
- United Therapeutics Corporation$21K
- Boston Scientific$44
- Genentech, Inc.$33
Across 97 payments — averaging $11,929 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| Boehringer Ingelheim | 74 | $35,946 |
| United Therapeutics Corporation | 44 | $21,185 |
| Boston Scientific | 2 | $44 |
| Genentech, Inc. | 1 | $33 |
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
How this compares
$57,208 in reported general payments places this provider in the 95th percentile of 3,302 internal medicine providers in North Carolina.
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

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| Boehringer IngelheimOfev | $35,946 | $380,91530 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 3,302 internal medicine providers in North Carolina.
