Has Diana Lam received payments from drug or device companies?

Yes. Drug and device makers reported $6,247 in general payments to Diana Lam across 294 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 Diana Lam 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 Diana Lam 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 294 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 48 manufacturers reported payments, led by AbbVie at 26.1% of the total. Reporting peaked in 2021 at $2,579 and has fallen 56.7% since, to $1,117 in 2025. Among physician assistant clinicians in VA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
