This is the South African table. Most ICD-10 results online are the United States’ ICD-10-CM, a different code set that South African medical schemes do not accept. Regulation 5 of the General Regulations under the Medical Schemes Act requires the diagnostic code on every account, and the Master Industry Table is the list it is coded from.
