What does a taxonomy code look like?
Ten characters, for example a code for a family medicine physician or a licensed clinical social worker. The code set is maintained by the National Uniform Claim Committee and updated twice a year.
Why isn't it enough to know a provider's specialty?
Providers pick their own codes, often once, when they get an NPI. The code may not match what they actually do today. A cardiologist who mainly does electrophysiology looks the same as a general cardiologist.
What helps?
Looking at what a provider actually treats and performs, for example from claims, gives a truer picture of their clinical focus.
