Code Description

ICD-10 R19.02 is a billable code used to indicate a diagnosis of left upper quadrant abdominal swelling, mass and lump.

Key Diagnostic Point:

R19.02 refers to the clinical presentation of swelling, mass, or lump specifically located in the left upper quadrant (LUQ) of the abdomen. This symptom can arise from various underlying conditions, including organ enlargement (such as splenomegaly), tumors, cysts, or inflammatory processes. Patients may present with associated symptoms such as pain, discomfort, or changes in bowel habits. Physical examination may reveal a palpable mass, tenderness, or signs of peritoneal irritation. Diagnostic imaging, such as ultrasound or CT scans, is often employed to characterize the mass and determine its etiology. Laboratory tests may include complete blood counts, liver function tests, and tumor markers, depending on the suspected underlying condition. Accurate documentation of the mass's characteristics, associated symptoms, and any relevant imaging or lab findings is crucial for appropriate coding and management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes (e.g., tumors, cysts, organ enlargement)
  • Need for detailed documentation of mass characteristics
  • Differentiation from other abdominal masses in coding
  • Potential for overlapping symptoms with other ICD codes

Audit Risk Factors

  • Inadequate documentation of mass characteristics
  • Failure to specify the location of the mass
  • Misclassification of the mass type (benign vs malignant)
  • Lack of supporting imaging or lab results

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed history and physical examination notes, including mass characteristics and associated symptoms.

Common Clinical Scenarios

Patients presenting with LUQ pain and palpable mass during routine examinations.

Billing Considerations

Consideration of chronic conditions that may contribute to mass formation, such as liver disease.

Emergency Medicine

Documentation Requirements

Acute care documentation must include immediate assessment findings, imaging results, and treatment plans.

Common Clinical Scenarios

Patients presenting with acute LUQ pain and signs of possible splenic rupture or other urgent conditions.

Billing Considerations

Rapid assessment and documentation are critical due to the potential for life-threatening conditions.
