Has John David received payments from drug or device companies?

Yes. Drug and device makers reported $59,005 in general payments to John David across 196 transactions between 2019–2025. Most Open Payments records nationally are meals worth under $20; a reported payment is not evidence of wrongdoing.

Does a payment mean John David 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.

Where does this information about John David come from?

The U.S. Centers for Medicare & Medicaid Services. Payments come from Open Payments, published under the Physician Payments Sunshine Act. Billing and prescribing figures come from the Medicare Physician & Other Practitioners and Part D Prescriber public use files for 2024.

Medicare billing

Part B allowed, 2024

$287,040

Medicare patients

Services billed

1,459

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.
