What this record shows
This record is dominated by food and beverage: $273 of the $310 with a category attached, or 88.1%. It is spread thinly across 8 manufacturers, the largest accounting for just 21.6% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $156 and has fallen 81.3% since, to $29 in 2025.
Across 13 payments — averaging $23.86 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
Too few clinical pathology/laboratory medicine providers in Marylandto place this figure against a meaningful peer group, so we don't.
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.
