Portable Personal Health Record
In addition to multiple account access, UnitedHealth Groups new cards will also provide access to an individuals Personal Health Record, making critical health information highly portable. This will allow patients to provide their physicians with secure access to an online medical history summary (currently available via the myuhc.com® website). A swipe of the card will give a physician access to the Personal Health Record. That Personal Health Record uses claims data and other data elements to automatically compile a comprehensive summary of medical conditions, medication history, significant medical interventions and laboratory results. In addition, it can be augmented by patients who choose to provide details such as allergies, immunizations and family history.
