The DocGraph Edge data set contains very detailed information on referral patterns between CMS healthcare providers. The data can be used to understand referral patterns within any community in the United States. The data sets are very large and are structured for use in network analysis. Providers are identified by their provider identification number.

The basic record structure is simple:

FirstNPI, SecondNPI, SharedTransactionCount, PatientTotal, SameDayTotal

The PatientTotal field is the total number of the patients involved in a treatment event (a healthcare transaction), which means that you can now tell the difference between high transaction providers (lots of transactions on few patients) and high patient flow providers (a few transactions each but on lots of patients).
