Our reference data visibility into how healthcare providers are interconnected and operate. Our dataset spans more than 30 unique reference categories such as practice locations, financial performance, contact information, and organizational hierarchy. We also apply data science to generate new intelligence you can only get with Definitive Healthcare. For example, our Claims-Based Specialty analytic uses procedure claims and distinct reference and affiliation data points to identify specialties, eliminating the distraction of unreliable and outdated self-reported information.
