Payments from drug & device makers

What this record shows

The money is spread across several categories — consulting fees (55.5%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. 13 manufacturers reported payments, led by Vertex at 34.8% of the total. 2025 is the largest year on record at $5,496, 5.8 times the $949 reported in 2019. Among pain medicine clinicians in SC with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.

Medicare billing

Part B allowed, 2024

$80,242

Medicare patients

323

Services billed

1,036

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.
