Why ICD-10 codes are important
The diagnostic code you use needs to be identical to that used by the surgeon. The date of service should correspond to the date of the surgery. Use the same surgical CPT procedure code used by the surgeon, but add the -55 modifier to signify that you are rendering the postoperative care.

ICD-10-CM Code for Ileus, unspecified K56.
K56. 7 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Introduction. Postoperative ileus is an abnormal pattern of slow or absent gastrointestinal motility in response to surgical procedures.
Z48. 815 - Encounter for surgical aftercare following surgery on the digestive system | ICD-10-CM.
Similarly, the ICD-10-CM alphabetic index under the main term “ileus” has a subterm or essential modifier “postoperative” and points to code K91. 89 with a description of “other postprocedural complication and disorders of the digestive system” and a “use additional code” note.
Ileus is a temporary and often painful lack of movement in the intestines. It is a serious condition because, if left untreated, it can cut off blood supply to the intestines and cause tissue death. This can result in an intestinal tear or infection of the abdominal cavity that can be life threatening.
Mechanical ileus affects the small bowel more often than the large bowel, in a ratio of 4:1. Small-bowel ileus is usually due to adhesions, while large-bowel ileus is usually due to cancer.
Causes of an ileus Surgery - Especially abdominal surgery, for any reason; surgery is the most common cause of ileus. This is due to manipulation of the intestines and exposure to the open air. This causes the intestines to go to sleep for up to several days after surgery.
Postoperative ileus (POI) is a transient inhibition of gastrointestinal (GI) motility that involves the entire GI tract (1). Prolonged POI is characterized by abdominal distention, nausea, vomiting and delayed passage of flatus and stool.

ICD-10 Code for Other intestinal obstruction- K56. 69- Codify by AAPC.
The term ‘postoperative’ can mean either a time frame (i.e., there is expected ileus occurring after a surgery) or complication (there is significant ileus after surgery that is unexpected.) The documentation in the record must be read to determine the meaning.
If the physician clearly documents or confirms that the ileus is not a surgical complication, but just occurred in the postoperative period, then only K56.7 (Ileus, unspecified) would be reported. If the physician clearly documents or confirms that the ileus is not a surgical complication, but just occurred in the postoperative period, ...
Use of some encoders are leading coders to the incorrect code. Ileus does not always involve intestinal obstruction and may or may not be a true postoperative complication. Many times ileus is a normal result and expected outcome of a surgery and it is not considered a true complication. A physician query may be necessary to clarify.
