The Operational Medicine Care Delivery Platform (OpMed CDP) represents a transformative advancement in health care data integration through its seamless mapping and interoperability with MHS GENESIS. A key component of this integration is the accurate mapping of standardized medical code sets, including ICD-10, SNOMED, CPT-4, and other applicable terminologies, to ensure consistent and precise data exchange between Military Health System electronic health record applications. This robust data mapping enables providers receiving casualties to access a unified, comprehensive patient record that eliminates the fragmentation inherent in legacy systems, such as AHLTA-T or HALO. By harmonizing clinical terminologies and ensuring interoperability, health care providers gain immediate access to complete patient histories, treatment records, and clinical data across the entire continuum of care. The bi-directional data flow ensures that critical patient information, encoded in standardized formats, is automatically synchronized and available to all stakeholders, from point-of-injury care through definitive treatment facilities in both connected and disconnected environments. The integration of OpMed CDP and MHS GENESIS was rigorously evaluated through joint operational assessments, testing, and Service experimentation designed to validate the seamless flow of data into OpMed CDP via the Operational Medicine Data Service (OMDS) and its subsequent transmission out of theater to MHS GENESIS. These efforts demonstrated the ability of the integrated systems to support real-time, actionable patient data exchange, ensuring that critical information is available to providers both in theater and at higher roles of care. By enabling efficient data flow and reducing reliance on legacy systems such as the Joint Longitudinal Viewer, this integration enhances operational readiness, improves care coordination, and supports critical decision-making in dynamic operational environments. The standardized coding and interoperability achieved through this framework ensure warfighters receive optimal care, while reducing system complexity and improving the efficiency of military health care networks.
