Has Duncan Langguth received payments from drug or device companies?

Does a payment mean Duncan Langguth did something wrong?

No. Federal law requires drug and device makers to report almost every transfer of value to a physician, including a $14 sandwich at a lunch presentation. Consulting fees, research funding and royalties to device inventors are ordinary, legal parts of medicine. This site reports what was disclosed; it makes no allegation.

Medicare billing

Part B allowed, 2024

$34,070

Medicare patients

131

Services billed

434

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.
