Taxonomy versus claims-based specialties
When healthcare providers register for a National Provider Identifier (NPI) number, they select a taxonomy that reflects their specialization and education. This data point, however, may become outdated as a provider finishes training or branches into a sub-specialty focus.
To more accurately reflect a provider’s practice patterns, we assign them a claims-based specialty in our PhysicianView product.
In the list below, we spotlight differences in taxonomy-based specialties and claims-based specialties to see areas where our healthcare commercial intelligence better classifies the providers in our PhysicianView product.

Claims-based specialty better categorizes nearly 18,000 internal medicine doctors
Ten of the 15 pairs of NPI-based and claims-based specialties provide more granular therapy area information for 17,850 providers identified with an internal medicine taxonomy code. These physicians are more accurately described as cardiology, gastroenterology, pulmonology and nephrology specialists when their diagnosis and procedure activity are taken into account.
Why are claims-based medical specialties important?
Compared to self-reported taxonomies, claims-based specialties in PhysicianView use healthcare commercial intelligence to better represent the type of clinical activity a provider performs. It allows for categorization of physicians based on their expertise and provides an up-to-date view of the procedures they’re performing.
For example, if an endocrinology professional association wants to target all endocrinologist providers, they would miss more than 1,300 potential contacts that have an internal medicine taxonomy but bill predominantly for endocrinology codes.
Or, if a biopharma company wants to know more about doctors who treat cancer patients, they could miss more than 1,500 providers with an oncology claims-based specialty who have a different taxonomy-based specialty.
