Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.9% of the total across 365 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 19 manufacturers, the largest accounting for just 14.9% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $2,026, 9.4 times the $216 reported in 2019. Among psychiatry 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.
Across 365 payments — averaging $19.55 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
How this compares
$7,136 in reported general payments places this provider in the 90th percentile of 624 psychiatry providers in South 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.

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 |
|---|---|---|
| Johnson & JohnsonInvega Sustenna, Invega Trinza | $1,060 | $499,729101 claims |
| Alkermes, Inc.Aristada, Lybalvi | $473 | $184,39483 claims |
| Otsuka America Pharmaceutical, Inc.Abilify Maintena, Rexulti | $711 | $118,66857 claims |
| Takeda Pharmaceuticals U.S.A., Inc.Trintellix | $166 | $11,75614 claims |
| Teva Pharmaceuticals USA, Inc.Loxapine | $904 | $83116 claims |
| Almatica Pharma LLCSertraline Hcl | $14 | $698111 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 90th percentile of 624 psychiatry providers in South Carolina.
