Has Lynna Bui received payments from drug or device companies?

Yes. Drug and device makers reported $12,539 in general payments to Lynna Bui across 224 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 Lynna Bui 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.
