A word of caution about these numbers
A payment does not mean your doctor is compromised or acting unethically. Most of these entries are drug samples left for patients, or lunch brought in for the office staff, and the amounts are usually small. Research funding and speaking at medical meetings are also normal parts of a clinical career.
As a rough guide, a total under $15,000 a year is usually not a concern. Much larger sums, especially from one company whose product your doctor recommends to you, are worth asking about. You are allowed to ask.
