Abdominal tenderness

Code Description

ICD-10 R10.81 is a billable code used to indicate a diagnosis of abdominal tenderness.

Key Diagnostic Point:

Abdominal tenderness is a clinical sign characterized by discomfort or pain upon palpation of the abdomen. It is often indicative of underlying pathology and can be associated with a variety of gastrointestinal, urological, and gynecological conditions. Tenderness may be localized or generalized, and its presence can help clinicians narrow down differential diagnoses. Common causes of abdominal tenderness include appendicitis, pancreatitis, cholecystitis, diverticulitis, and bowel obstruction. The assessment of abdominal tenderness is a critical component of the physical examination, often guiding further diagnostic testing and management. Laboratory findings may include elevated white blood cell counts or imaging studies that reveal structural abnormalities. Accurate documentation of the location, severity, and characteristics of the tenderness is essential for appropriate coding and treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of tenderness (localized vs. generalized)
  • Need for correlation with other clinical findings
  • Potential overlap with other abdominal pain codes
  • Differentiation from other abdominal symptoms

Audit Risk Factors

  • Inadequate documentation of the location and severity of tenderness
  • Failure to link tenderness to a definitive diagnosis
  • Misuse of R10.81 when a more specific code is available
  • Inconsistent coding practices across providers
