About K56.5

K56.5 is the ICD-10-CM diagnosis code for intestinal adhesions [bands] with obstruction (postinfection). 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 3 subcodes must be used instead.

Within K56 (paralytic ileus and intestinal obstruction without hernia), K56.5 is specifically for intestinal adhesions [bands] with obstruction (postinfection). Related codes cover paralytic ileus (K56.0), intussusception (K56.1), Volvulus (K56.2), Gallstone ileus (K56.3), other impaction of intestine (K56.4), other and unspecified intestinal obstruction (K56.6) and ileus, unspecified (K56.7).

To report this condition, pick the subcode that matches the documentation: K56.50 (obstruction), K56.51 (obstruction) and K56.52 (obstruction).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (title revised).
