Chapter 5: Coding


Surveillance programmes should record diagnostic information about congenital anomalies correctly and accurately, in a standardised way. Programmes can use the international standard classification system for diagnosing diseases, the International Classification of Diseases and Related Health Problems (ICD-10) and related ICD-10 modifications, to classify and record diagnostic information. Programme staff should be trained so that those involved record and review information consistently.

Chapter 5 provides:

  • An overview of coding congenital anomalies
  • Considerations for implementing coding processes, such as the training of staff
  • Information about coding multiple congenital anomalies
  • Specific guidance for staff on using photographs, diagnostic information, and clinical descriptions when coding.
