Hourglass stricture and stenosis of stomach

This code represents an acquired narrowing or constriction of the stomach, specifically characterized by an hourglass-like deformity. This stricture or stenosis impedes the normal passage of food through the stomach. It is typically a chronic condition resulting from inflammation, scarring, or other pathological processes.

Assign this code when documentation clearly indicates an acquired hourglass stricture or stenosis of the stomach. This diagnosis is often supported by endoscopic findings, imaging studies (e.g., barium swallow, CT scan), and clinical symptoms such as dysphagia, early satiety, or vomiting. Use this code for conditions that develop after birth, differentiating it from congenital forms.

• Differentiate carefully between acquired (this code) and congenital hourglass stomach (Q40.2), which is an Excludes1.
• Do not confuse with hourglass contraction of the stomach (K31.89), which is also an Excludes1 and represents a functional rather than structural narrowing.
• Ensure documentation specifies "stricture" or "stenosis" and not merely a "contraction" to accurately apply this code.
