The DocGraph Journal

What The DocGraph Journal does

The DocGraph Journal is the publishing identity for the DocGraph Hop Teaming Medicare Referral Public Use File, operated by CareSet Systems, a private for-profit company headquartered in Houston, Texas. Founded in 2012 after initiating FOIA requests to HHS and CMS, CareSet built and released the first open dataset to map patient-sharing relationships among U.S. healthcare providers, derived from Medicare claims data. CareSet publishes annual DocGraph releases covering 2014 through 2022, each available under a non-commercial license at no cost to researchers and journalists.

The company's underlying technology is a claims-data graph product, not a software platform: it ingests publicly released Medicare claims, constructs provider-to-provider collaboration edges based on shared patients, and releases the resulting public-use file with longitudinal methodology. Distribution is dual-mode: self-serve free downloads via Dropbox links for academic and journalistic use, and quote-based direct-sales engagement (a 'Request Demo' CTA on the website) for commercial licensing. Additional reach comes through the company's VRDC Users Group and ongoing federal regulatory advocacy around healthcare data transparency.

CareSet's primary customers are healthcare services researchers at academic institutions, healthcare policy journalists, and an emerging secondary segment of healthcare industry leaders (insurers, executives, policymakers) accessing data via commercial licensing. Revenue is generated from commercial licensing of the DocGraph dataset to organizations with non-research use cases; terms and pricing are negotiated through direct inquiry. No revenue, funding, parent company, or acquisitions are disclosed, and the firm operates with 1-10 employees, indicating a small, niche commercial footprint layered on top of a broadly consumed open data asset.

Direct peers

• Cotiviti: Payment integrity and analytics firm that works with Medicare, MA, and commercial claims to derive provider and network insights. Overlaps with DocGraph on Medicare claims analytics and provider-network intelligence for payer customers.
• Definitive Healthcare: Provides healthcare commercial intelligence built on claims and reference data, including provider network and referral analytics. Closely comparable to DocGraph's Medicare referral PUF use cases, but serves enterprise customers with proprietary, multi-source datasets.
• Health Catalyst: Healthcare data and analytics platform serving providers and payers with population health, value-based care, and network analytics. Comparable to DocGraph because both target value-based care and provider network questions using claims-derived data.
• Komodo Health: Healthcare analytics company that aggregates de-identified claims data (including Medicare) to map provider networks, patient journeys, and treatment patterns. Most directly comparable to DocGraph's provider-patient-sharing analytics, but at much greater scale and with commercial-only data licensing.
• Innovaccer: Healthcare data activation platform unifying claims, EHR, and social determinants data for value-based care. Comparable to DocGraph on value-based-care analytics and the provider-network data interoperability themes highlighted in CareSet's research.
• Arcadia: Healthcare data platform focused on value-based care performance and population health using aggregated claims and EHR data. Comparable to DocGraph because both serve value-based contracting analytics and provider network measurement needs.
• Trilliant Health: Healthcare market analytics platform using claims, demographics, and competitive intelligence to inform provider strategy. Comparable to DocGraph's healthcare industry leaders segment and provider-network reporting use cases.

Broad incumbents

• IQVIA: Global healthcare data and analytics company with deep claims, provider, and life sciences datasets. Comparable to DocGraph's Medicare claims analytics at the conceptual level, though IQVIA operates across payers, providers, and life sciences at enterprise scale.
• Optum (UnitedHealth Group): Largest US healthcare data and analytics franchise, with deep Medicare, MA, and commercial claims assets used for value-based care and network analytics. Comparable to DocGraph on Medicare data analytics, but embedded inside a much broader payer-services portfolio.
• LexisNexis Risk Solutions (Healthcare): Provides large-scale healthcare provider and patient data assets used for analytics, network management, and risk adjustment. Comparable to DocGraph's provider-network intelligence use cases but operating across many adjacent verticals at much larger scale.
