Rheumatology in California
808 providers, $32,571,991 in total reported payments from drug and device makers. Ranked below by lifetime general payments. The median provider in this group received $1,724.
Ranking high here usually means a consulting or royalty arrangement, not wrongdoing. Payments to device inventors and trial investigators are legal, disclosed, and concentrated in a small number of people — which is exactly why a list like this has a steep top and a long flat tail.
What Medicare pays rheumatology clinicians in California
Across 570 rheumatology clinicians in California who billed Original Medicare Part B in 2024, Medicare allowed $293,049,215 in total — an average of $514,121 each, of which $138,038 was for services and the rest for drugs administered in the office.
This is not a salary. 73% of this figure is the cost of drugs administered in the office — chemotherapy, infusions and injections that Part B pays for and the practice has already bought. That money passes through; it is not earnings. The rest is what Medicare allowed for services these clinicians billed — Original Medicare fee-for-service only. It excludes Medicare Advantage, which now covers more than half of Medicare enrollees, along with Medicaid and every commercial insurer, so for most clinicians it is a fraction of their practice. It is also gross revenue: staff, rent, supplies and malpractice premiums all come out of it before anyone is paid. Anyone quoting a figure like this as physician pay is misreading it.
