Postgastric surgery syndromes

This code represents a range of adverse conditions that can develop following gastric surgery, such as gastrectomy, gastric bypass, or vagotomy. These syndromes include dumping syndrome, afferent loop syndrome, efferent loop syndrome, and alkaline reflux gastritis, among others. They result from altered anatomy and physiology of the gastrointestinal tract after surgical intervention.

Use this code when documentation clearly indicates a patient is experiencing symptoms or complications directly attributable to a previous gastric surgical procedure. This typically applies to patients presenting with issues like rapid gastric emptying, bile reflux, or obstruction of surgically created loops. Documentation should specify the type of postgastric surgery syndrome.

• Do not use this code for general post-operative complications not specifically related to gastric surgery syndromes.
• Always sequence this code after the primary diagnosis for the current encounter, if applicable, or as the primary diagnosis if the syndrome is the reason for the encounter.
• Ensure the medical record explicitly states a connection between the patient's symptoms and a prior gastric surgical intervention.
