Through program year 2025, David Charytan of New York, NY is reported in the CMS Open Payments database as having received $163,630 across 106 general payments and $8,400 in research payments paid to them. Separately, studies naming them as principal investigator received $1,115,254 in research payments, paid to institutions rather than to them.
No combined total General, research and ownership are kept apart. Each is reported under its own rules, and ownership is not money that moved at all but the value of a stake held. A meal, a clinical trial grant and a shareholding do not add up to anything meaningful, so this site does not add them. The principal-investigator line is research money paid to institutions for studies they led — not to them — and is not added to anything either.
General payments for this record sit in the 98th percentile of Nephrology profiles with reported payments. Percentile describes the distribution, not the conduct.

Breakdown
A payment can name more than one product, so these amounts overlap and do not add up to the general-payment figure.

The 10 drugs with the highest cost, of 12 counted.
Drug cost is what was paid for the drugs at the pharmacy — by Medicare, the patient and others — and is not money to the prescriber. Medicare Part D only: drugs dispensed to Medicare beneficiaries. A drug with fewer than 11 claims for this prescriber is not published, so a missing drug does not mean zero. The medians are for the 9,003 Part D prescribers listed as Nephrology; they describe a distribution and say nothing about conduct.

How to read this page
What each amount means, and what it does not mean.
What this means
U.S. law requires drug and medical device manufacturers to report payments and transfers of value they make to physicians and teaching hospitals. The Centers for Medicare & Medicaid Services publishes that record each year. This page shows what was reported about this person, and nothing else.
An ownership interest is different from the other two. It is not a payment: it is a stake — shares, options, a partnership holding — that a physician or an immediate family member held in a manufacturer during that year. The figure shown is what the stake was reported to be worth.
Research payments frequently pass through a clinician to the institution running a trial, and rarely represent personal income. They should be read differently from general payments.
