About coding neurogenic ileus
The ICD-10-CM code for neurogenic ileus is K56.0 (Paralytic ileus). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K56.0.
Within K56 (paralytic ileus and intestinal obstruction without hernia), K56.0 is specifically for paralytic ileus. Related codes cover intussusception (K56.1), 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).
Don't report K56.0 together with the conditions in its Excludes1 note: gallstone ileus (K56.3), ileus NOS (K56.7) and obstructive ileus NOS (K56.69-).
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.
