Medicare billing

Part B allowed, 2024
$212,131
Medicare patients
487
Services billed
4,368

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.

CompanyPaid to this providerPart D cost of their drugs
Fresenius USA Marketing, Inc.Velphoro$382$216,03050 claims
AstraZenecaFarxiga, Lokelma$114$36,57844 claims
ANI Pharmaceuticals, Inc.Valsartan$22$63339 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 180 nephrology providers in South Carolina.
