Building the Foundation for Medicare Data Transparency
CareSet’s work began with a series of FOIA requests to HHS and CMS, seeking a clearer view of how providers collaborate within the healthcare system. These efforts led to access to Medicare data, culminating in the release of the DocGraph Hop Teaming Medicare Referral Public Use File (PUF)—the first dataset to map patient-sharing relationships among providers.
This dataset opened new opportunities to examine referral patterns, provider collaboration, and healthcare delivery. Today, CareSet continues to expand access to Medicare data, helping researchers, journalists, and industry leaders use this information to support analysis and decision-making.
