About This Data

ProPublica obtained prescribing data from Medicare’s prescription drug benefit, known as Part D, under the Freedom of Information Act. The data for 2011 includes nearly 1.2 billion prescriptions written by 1.6 million doctors, nurses and other providers. This database lists about 364,000 of those providers who wrote 50 or more prescriptions for at least one drug that year. About three-fourths went to patients 65 and older; the rest were for disabled patients. Methodology »
