Payments from drug & device makers

What this record shows

This record is dominated by travel and lodging: $7,601 of the $9,702 with a category attached, or 78.3%. 8 manufacturers reported payments, led by Eli Lilly at 52.0% of the total. Among internal medicine clinicians in KS 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.

Medicare billing

Part B allowed, 2024
$354,218
Medicare patients
1,753
Services billed
6,087

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.

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.

CompanyPaid to this providerPart D cost of their drugs
PfizerEliquis$25$34,14151 claims
MerckJanuvia$4,550$33,20525 claims
AbbVieSynthroid$28$3,02343 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 705 internal medicine providers in Kansas.
