Code Description

ICD-10 R10.0 is a billable code used to indicate a diagnosis of acute abdomen.

Key Diagnostic Point:

Acute abdomen refers to a sudden onset of severe abdominal pain that may indicate a serious underlying condition requiring immediate medical attention. Symptoms often include sharp or cramping pain, tenderness upon palpation, and may be accompanied by nausea, vomiting, fever, or changes in bowel habits. The acute abdomen can arise from various causes, including appendicitis, pancreatitis, bowel obstruction, perforated ulcers, or ectopic pregnancy. Clinical evaluation typically involves a thorough history and physical examination, laboratory tests (such as complete blood count, electrolytes, and liver function tests), and imaging studies (like ultrasound or CT scans) to identify the underlying cause. Prompt diagnosis and treatment are crucial to prevent complications such as sepsis or organ failure.
