What this record shows

That places this record below the midpoint for retina specialist clinicians in MD, where the typical reported total is $3,416.
Across 6 payments — averaging $50.60 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$304 in reported general payments places this provider in the 5th percentile of 47 retina specialist providers in Maryland.
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.
