About K56.4

K56.4 is the ICD-10-CM diagnosis code for other impaction of intestine. It belongs to category K56 (paralytic ileus and intestinal obstruction without hernia), block K55-K64 (other diseases of intestines) 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 K56, choose K56.4 (Other impaction of intestine) only when documentation doesn't support a more specific option: paralytic ileus (K56.0), intussusception (K56.1), Volvulus (K56.2), Gallstone ileus (K56.3), intestinal adhesions [bands] with obstruction (postinfection) (K56.5), other and unspecified intestinal obstruction (K56.6) and ileus, unspecified (K56.7).

To report this condition, pick the subcode that matches the documentation: K56.41 (impaction) and K56.49 (intestine).

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