National Uniform Claim Committee (NUCC)


The National Uniform Claim Committee (NUCC) is chaired by the American Medical Association (AMA), with the Centers for Medicare and Medicaid Services (CMS) as a critical partner. The NUCC maintains the Health Care Provider Taxonomy, a standardized code set used in healthcare transactions specified by HIPPA and the National Provider Identifier application. The code set is structured into three distinct levels: Provider Grouping, Classification, and Area of Specialization.

Cybersyn NUCC data provides:

  • National Provider Identifiers (NPIs) mapped to NUCC taxonomy codes and business groups

  • NUCC taxonomy codes mapped to CMS Medicare speciality codes

As with all Public Domain datasets, Cybersyn aims to release data on Snowflake Marketplace as soon as the underlying source releases new data. We check periodically for changes to the underlying source and, upon detecting a change, propagate the data to Snowflake Marketplace immediately. See our release process for more details.


All Cybersyn products follow the EAV (entity, attributes, value) model with a unified schema. Entities are tangible objects (e.g. geography, company) that Cybersyn provides data on. All timeseries' dates and values that refer to the entity are included in a timeseries table. Descriptors of the timeseries are included in an attributes table. Data is joinable across all Cybersyn products that have a GEO_ID. Refer to Cybersyn Concepts for more details.
