About K41.1

K41.1 is the ICD-10-CM diagnosis code for bilateral femoral hernia, with gangrene. It belongs to category K41 (femoral hernia), 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 2 subcodes must be used instead.

Within K41 (femoral hernia), K41.1 is specifically for bilateral femoral hernia, with gangrene. Related codes cover bilateral femoral hernia, with obstruction, without gangrene (K41.0), bilateral femoral hernia, without obstruction or gangrene (K41.2), unilateral femoral hernia, with obstruction, without gangrene (K41.3), unilateral femoral hernia, with gangrene (K41.4) and unilateral femoral hernia, without obstruction or gangrene (K41.9).

To report this condition, pick the subcode that matches the documentation: K41.10 (not specified as recurrent) and K41.11 (recurrent).

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