Prescribed Minimum Benefits in Q23. A medical scheme must fund the diagnosis, treatment and care of a PMB condition in full, within its rules on designated providers and treatment protocols. The PMB code and treatment component beside each code come from the Council for Medical Schemes’ PMB Coded List; the scheme decides whether a given claim qualifies.

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.
