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 »

Caveats
  • No comparisons are shown if 10 or fewer prescribers in the state share this specialty.
  • The list of top drugs includes only those for which this provider wrote 50 or more prescriptions, but all prescriptions are counted in the summary totals at the top.
  • The calculation of “Risky Drugs to Seniors” does not include drugs for which a provider wrote 11 or fewer prescriptions because Medicare redacted the information to protect patient privacy.
  • Comparisons do not take into account the medical conditions of patients. Medications for certain conditions do not have generic alternatives, so patients would receive more expensive brand name drugs.
  • This provider's address and specialty information was last updated on Jan. 3, 2008.
  • Comparisons are based on each provider’s current address, not necessarily where he or she worked during the time period covered in this database.
