Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 98.6% of the total across 27 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Cipla USA Inc. accounts for 72.2% of it on its own, with 9 other manufacturers making up the rest. Reporting peaked in 2021 at $1,360 and has fallen 96.9% since, to $43 in 2025.

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.

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

$1,805 in reported general payments places this provider in the 60th percentile of 102 infectious disease providers in South Carolina.

Medicare billing

Part B allowed, 2024
$66,690
Medicare patients
153
Services billed
560

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.
