Unified Comment from CDC

  • General Comment: Recommend moving this element to a new “Cancer Data” USCDI Class (not in the Observation class).   
  • Additional Use Case: This is a standard data item used by central cancer registries in all states. Data received through data exchange from medical facilities (e.g., laboratories, hospitals, physician EHRs, etc.) to central cancer registries for CDC and NCI’s national cancer surveillance systems, as required by law.
