# Reference Data

## Overview

Ursa Health has synthesized international code sets, best-in-class third-party resources, and its own proprietary intelligence to create a set of look-up tables that are vital ingredients for enriching healthcare’s data ontologies. No need for you to do any research, acquire any additional licenses, or perform any new set-up — we do all the painstaking compilation and maintenance of this valuable healthcare reference material for you. So instead of working with an indecipherable 11-digit NDC pharmacy code, for example, you’re viewing drug names, the way each maps to a therapeutic class of drugs, average pricing, and more.
