Manifest MedEx provides the actionable clarity health plans need to manage population health and improve member outcomes. By securely bringing together clinical, claims, behavioral health, and social drivers of health (SDOH) data, we bridge the gap between fragmented silos and whole person health. Health plans rely on us as a central source for the most comprehensive California longitudinal health records, enabling them to manage better care for their members.

Advancing Health Plan Priorities


Use real-time hospital event notifications (ADT) to ensure members get the care they need in the hospital and upon discharge


Access comprehensive longitudinal health summaries from the state’s largest database to manage population health


Use NCQA-validated data to improve quality scores and reduce the burden of HEDIS® reporting


Streamline performance with “uplifted” or enhanced data services that provide more accurate data than standard HIEs


Simplify risk adjustment with easy-to-consume, clinical chart notes

Real-World Impact

California Roots. National Connectivity.

Ready to explore what’s possible with the state’s largest non-profit health data network?

Manifest MedEx provides health plans with real-time hospital event notifications (ADT), comprehensive longitudinal health records, NCQA-validated data to streamline HEDIS reporting, clinical notes for risk adjustment, and enhanced data services that bring together more accurate clinical, claims, behavioral health, and social care data to support population health management and improve member outcomes. All data is exchanged securely and only as permitted under HIPAA and California privacy law.

Yes. Manifest MedEx has earned NCQA’s Data Aggregator Validation (DAV) designation every year since that program’s official launch in 2021, building on MX’s participation in earlier DAV pilot efforts dating back to 2019. This means health plans can use MX’s validated data as standard supplemental data for HEDIS reporting without needing separate primary source verification from individual providers, saving time and reducing the administrative burden of “chart chasing” each year.

Enhanced Data Services, also called “uplifted” data, go beyond standard data by normalizing and mapping local or non-standard provider codes to standard codes. This includes both Enhanced NCQA Data Aggregator Validation Services, which improves the accuracy of data used for HEDIS reporting, and Enhanced Longitudinal Patient Summaries, which provide health plans with more accurate, complete Consolidated Clinical Document Architecture (C-CDA) summaries of a member’s medical history. Together, these services from Manifest MedEx help health plans avoid data errors and underreporting caused by inconsistent coding, giving them a clearer and more reliable picture of member health while keeping data use limited to permitted, authorized purposes.

Manifest MedEx helps Medi-Cal managed care plans (MCPs) succeed under CalAIM by supporting Enhanced Care Management (ECM) and Community Supports through real-time ADT notifications, longitudinal health records, and social drivers of health (SDOH) data, including Z-codes used for community support referrals. This helps MCPs start care coordination immediately when a member is admitted, discharged, or transferred. MX also helps plans meet data-sharing requirements like those in DHCS All Plan Letter (APL) 23-029, all in accordance with member privacy protections and consent requirements under CalAIM.

Manifest MedEx offers flexible data delivery options designed to fit directly into a health plan’s existing systems, including CCDA forwarding and message forwarding services. These data feeds send longitudinal health records and clinical documents directly into the health plan’s own systems and workflows, always in compliance with HIPAA and other applicable privacy laws governing how member health information may be used and shared.

Yes. Manifest MedEx offers Clinical Notes for Risk Adjustment, a data service that helps health plans access relevant clinical documentation, already permitted for treatment, payment, and healthcare operations purposes, to support accurate risk adjustment reporting and coding.
