Summary

Accurate diagnosis records are essential for research, billing, and patient care. This study compared diagnostic data in insurance claims and electronic health records for the same patients. Diagnostic information was often inconsistent across sources, and electronic records missed nearly half of all diagnoses, highlighting the need for better data completeness to support population health efforts.
