Left lower quadrant rebound abdominal tenderness

Code Description

ICD-10 R10.824 is a billable code used to indicate a diagnosis of left lower quadrant rebound abdominal tenderness.

Key Diagnostic Point:

Left lower quadrant rebound abdominal tenderness is a clinical sign that indicates irritation of the peritoneum, often associated with acute abdominal conditions. This sign is elicited during a physical examination when the examiner presses down on the left lower quadrant of the abdomen and then quickly releases the pressure. The patient experiences increased pain upon release, which suggests peritoneal irritation. Common causes of this sign include appendicitis, diverticulitis, and other inflammatory processes in the left lower abdomen. It is crucial for healthcare providers to assess this sign in conjunction with other symptoms such as fever, nausea, vomiting, and changes in bowel habits to determine the underlying cause. Laboratory findings may include elevated white blood cell counts and imaging studies may reveal inflammation or abscess formation. Accurate identification and documentation of rebound tenderness are essential for appropriate diagnosis and treatment planning.

  • Potential overlap with other ICD-10 codes for abdominal pain.

Audit Risk Factors

  • Inadequate documentation of the physical examination findings.
  • Failure to link the symptom to a definitive diagnosis.
  • Misinterpretation of rebound tenderness as a standalone diagnosis.
  • Inconsistent coding practices across different providers.
