Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.5% of the total across 241 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 24 manufacturers, the largest accounting for just 19.9% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $1,284, 2.9 times the $437 reported in 2019. That places this record below the midpoint for allergy & immunology clinicians in GA, where the typical reported total is $4,504.
Across 241 payments — averaging $21.93 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

How this compares
$5,286 in reported general payments places this provider in the 50th percentile of 107 allergy & immunology providers in Georgia.
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
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Dupixent SyringeDupilumab | 16 | $73,013 |
| Trelegy ElliptaFluticasone/Umeclidin/Vilanter | 13 | $14,457 |
| XhanceFluticasone Propionate | 11 | $6,603 |
| Ipratropium Bromide | 42 | $872 |
| Fluticasone Propionate | 20 | $345 |
| Famotidine | 14 | $156 |
| Prednisone | 11 | $20 |
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 |
|---|---|---|
| GSKTrelegy Ellipta | $934 | $14,45713 claims |
| Optinose US, Inc.Xhance | $436 | $6,60311 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 50th percentile of 107 allergy & immunology providers in Georgia.
