Situs inversus

This code represents situs inversus, a rare congenital condition where the major visceral organs are reversed or mirrored from their normal anatomical positions. This can involve all organs (situs inversus totalis) or only some (situs inversus with levocardia or dextrocardia).

Use this code when documentation explicitly states situs inversus, situs inversus totalis, or a complete reversal of organs. It is typically identified incidentally during imaging studies or clinical examination.

• Do not confuse with isolated dextrocardia or levocardia unless the entire visceral arrangement is reversed.
• Code any associated congenital anomalies or cardiac defects separately.
• This code is for the anatomical anomaly itself, not for symptoms or complications arising from it.
