Reporting payments is a legal requirement; large totals often reflect large product portfolios.
General and research payments are shown separately, never blended. Research payments are often institution-directed and tied to clinical trials.
General payments by year
General payments only, as reported to CMS. Research payments are totaled above and not included in these bars.
Specialties it works with most
Clinicians with the largest reported totals
