About coding Invagination
The ICD-10-CM code for Invagination is K56.1 (Intussusception).
Within K56 (paralytic ileus and intestinal obstruction without hernia), K56.1 is specifically for intussusception. Related codes cover paralytic ileus (K56.0), Volvulus (K56.2), Gallstone ileus (K56.3), other impaction of intestine (K56.4), intestinal adhesions [bands] with obstruction (postinfection) (K56.5), other and unspecified intestinal obstruction (K56.6) and ileus, unspecified (K56.7).
The conditions in its Excludes2 note aren't part of K56.1, but may be coded alongside it if the patient has both: intussusception of appendix (K38.8).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
