This lookup is a reference to the published code table, not coding advice. Code assignment is the treating practitioner’s responsibility, following the South African ICD-10 Coding Standards and Guidelines and the WHO ICD-10 volumes. GreenNotes does not warrant that the table is complete or current.

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.
