About K41

K41 is the ICD-10-CM diagnosis code for femoral hernia. It belongs to block K40-K46 (hernia) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: K41.0 (gangrene), K41.1 (gangrene), K41.2 (gangrene), K41.3 (gangrene), K41.4 (gangrene) and K41.9 (gangrene).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
