For specialty practices such as dermatology clinics, dental groups, and surgical centers, growth often depends on referrals. When a practice expands into a new city, leadership must quickly identify local primary care physicians, nurse practitioners, and physician assistants because these providers typically see patients first and play a key role in directing referrals to specialists.
Finding the right referring providers in a new market can be difficult. Traditional provider directories are often outdated or incomplete, or they may list individual clinicians but fail to show how those clinicians connect to larger health systems. Without that context, expansion teams can spend significant time verifying information before outreach even begins.
High-quality provider data helps simplify this process by revealing the structure of the local healthcare landscape. Veritas’s Provider Network and Affiliations Index is designed to provide that visibility across the United States healthcare system. The dataset includes more than 6.6 million active individual providers and 1.8 million facilities, along with 16 million network connections across 3,000 health systems. It captures key information for physicians, specialists, nurse practitioners, and physician assistants, while also mapping how those providers relate to hospitals, clinics, and health networks.
How Medical Practices Use Provider Affiliations to grow their business
Medical practices often use geographic subsets of Veritas’s Provider Index when planning expansion into a new region. For example, a clinic opening in a new metropolitan area can request a dataset containing all providers of a certain speciality (e.g. general practitioners) within a specific radius of its planned locations. Business development teams can then focus outreach efforts on the clinicians most likely to refer patients.
Affiliation data also provides important market context. Teams can see whether a provider operates independently or within a large hospital system. This distinction helps practices tailor their outreach strategy. Independent practices may require direct relationship building, while providers affiliated with large health systems may involve broader institutional partnerships.
Example: Nurse Practitioners specializing in family practice in New York

Streamlining Your Market Entry Strategy
The Veritas Provider Index can be delivered through flat files or cloud platforms, allowing practices to integrate the data into their internal tools and analytics workflows. The dataset focuses on professional reference and affiliation information and includes contact details for providers.
With a reliable view of provider networks and affiliations, medical practices can enter new markets with a clearer strategy. Instead of building referral relationships after opening a new location, expansion teams can begin mapping the local ecosystem and prioritizing outreach well in advance.
