Adult hypertrophic pyloric stenosis
ICD-10 K31.1 is a billable code used to indicate a diagnosis of adult hypertrophic pyloric stenosis.
Adult hypertrophic pyloric stenosis is a condition characterized by the abnormal thickening of the pyloric sphincter, which is located at the junction of the stomach and the small intestine. This thickening leads to a narrowing of the pylorus, resulting in gastric outlet obstruction. Clinically, patients may present with symptoms such as persistent vomiting, abdominal pain, and weight loss. The condition is often diagnosed through imaging studies such as ultrasound or upper gastrointestinal series, which can reveal the characteristic 'string sign' or delayed gastric emptying. The disease progression can lead to severe dehydration and electrolyte imbalances if not addressed promptly. Anatomically, the pylorus consists of the pyloric canal and pyloric sphincter, which play a crucial role in regulating the passage of food from the stomach to the duodenum. Diagnostic considerations include a thorough patient history, physical examination, and appropriate imaging to confirm the diagnosis and rule out other gastrointestinal disorders. Treatment typically involves surgical intervention, specifically a pyloromyotomy, to relieve the obstruction and restore normal gastric function.

K31.1 specifically covers adult hypertrophic pyloric stenosis, which is characterized by the thickening of the pyloric sphincter leading to gastric outlet obstruction. It is important to differentiate this condition from other types of pyloric stenosis that may occur in infants.
K31.1 should be used when the diagnosis of adult hypertrophic pyloric stenosis is confirmed, particularly when the clinical presentation aligns with the symptoms and diagnostic findings associated with this specific condition, as opposed to other gastrointestinal disorders.
Documentation for K31.1 should include a detailed patient history, physical examination findings, imaging results confirming pyloric stenosis, and any surgical notes if applicable. Clear documentation of symptoms and treatment plans is essential for accurate coding.
