Public records, made easier to understand.

Why this site exists

CMS Open Payments, NPPES, and public Medicare prescribing data already exist, but they live in separate datasets and are difficult for a patient to connect safely. This site turns those public records into a doctor-centered summary while keeping the source, year, and limits close to each conclusion.

These records are a starting point for informed questions, not a verdict about a doctor.

What we do

• Use NPI as the preferred stable doctor identifier and show disambiguation context when names are similar.
• Summarize reported Open Payments by year, company, and payment category.
• Keep products explicitly named on payment records separate from drugs associated with a paying company.
• Compare public Medicare Part D data only when the evidence boundary supports the comparison.
• Show source releases, years, matching methods, and important limitations.

What we do not do

• We do not rate doctors, create conflict scores, or publish moral rankings.
• We do not determine whether a payment influenced prescribing or medical care.
• We do not provide personalized medical advice.
• We do not claim that Medicare Part D represents all of a doctor’s prescribing.
• We do not let a doctor or company pay to hide, change, or improve a public-data result.

Who operates this site

Who Pays My Doctor? is an independent public-data project. It is not an official CMS, Medicare, pharmaceutical-company, medical-device-company, or physician-rating website.
