Diameter Health, a fast-growing leader in health data interoperability, has announced that it raised $18 million in a Series B funding round led by managed care organization Centene Corporation, with participation from existing investors Optum Ventures, LRVHealth, Connecticut Innovations and Activate Venture Partners. This brings Diameter Health's total funding to $30 million.

Diameter Health enables clinical insight through the normalization, cleansing, deduplication and enrichment of clinical data from across the care continuum. This creates a single, unified source of longitudinal structured patient information for improved care and actionable analytics. The Diameter Health platform empowers organizations that depend on multi-source data streams, such as Health Information Exchanges (HIEs), Accountable Care Organizations (ACOs), health systems and health plans, to realize greater value from their data.
