About coding intussusception
The ICD-10-CM code for intussusception is K56.1 (Intussusception). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K56.1.
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.
