Particle Health is a healthcare data interoperability platform that aggregates patient medical records from across the US healthcare system into a single RESTful API. Particle is connected to all three nationwide health information exchange networks (Carequality, CommonWell, eHealth Exchange), TEFCA / QHIN partners, state HIEs (Healthix in New York, Manifest MedEx in California), and Surescripts for pharmacy data. The platform exposes patient demographics, clinical resources, and document retrieval via FHIR R4, C-CDA, Flat, and Deltas formats, layered with deduplication, normalization, AI summarization (Particle Snapshot), real-time encounter and transition alerts (Particle Signal), and longitudinal patient journey tracking (Particle Navigator). Customer segments include value-based care organizations, payers, health systems, primary and specialty providers, and digital health developers.
