K91.8: Other postprocedural disorders of digestive system, not elsewhere classified

ICD-10 code K91.8 refers to other postprocedural disorders of the digestive system that are not classified elsewhere. Following a digestive system procedure, some patients may experience complications, which this category covers. These complications can affect different parts of the digestive system such as the esophagus, stomach, intestines, liver, gallbladder, and pancreas. Such disorders could be functional or structural changes due to the previous procedures and vary widely in symptoms. The symptoms usually depend on the affected area of the digestive system and may include discomfort, nausea, vomiting, changes in bowel movement, bleeding, or even severe pain. The presence and severity of these disorders often require further diagnostic investigation to determine the exact nature of the complication, its direct cause, and appropriate management strategy. It's important to note that these disorders are usually unintended consequences of procedures aimed at diagnosing or treating digestive system conditions.
