Acute dilatation of stomach

This code represents a sudden, significant distension of the stomach, often due to impaired gastric motility or outflow obstruction, leading to an accumulation of gastric contents. It is a serious condition that can cause severe abdominal pain, nausea, vomiting, and potentially lead to complications like gastric ischemia or perforation.

Use this code when documentation clearly indicates an acute, non-obstructive enlargement of the stomach. This typically occurs in post-operative patients, those with electrolyte imbalances, or individuals with severe systemic illness. Supporting documentation should include findings of a dilated stomach on imaging (e.g., X-ray, CT scan) and clinical signs of acute gastric distension.

• Differentiate from chronic gastric dilatation, which has a different underlying etiology and code.
• Ensure documentation specifies "acute" to justify this code; otherwise, consider unspecified gastric dilatation.
• Code any underlying cause or associated conditions, such as electrolyte imbalance or post-surgical state, as additional diagnoses.
