Has Joanna Lee received payments from drug or device companies?

Yes. Drug and device makers reported $1,617 in general payments to Joanna Lee across 67 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 Joanna Lee 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 Joanna Lee 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.

Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 67 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 29 manufacturers, the largest accounting for just 12.6% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $837 and has fallen 96.0% since, to $33 in 2025. That places this record below the midpoint for surgical oncology clinicians in CA, where the typical reported total is $1,777.
