Diagnosis Overview

What is Enlarged Spleen?
Essential facts and insights about Enlarged Spleen

Key Clinical Considerations:

  • Abdominal pain or discomfort
  • Early satiety
  • Fatigue or weakness
  • Key diagnostic tests: Ultrasound, CT scan, CBC showing leukopenia or thrombocytopenia
  • Physical exam findings: Palpable splenomegaly, tenderness in the left upper quadrant

Clinical Information

Clinical Criteria & Documentation Requirements

  • Required documentation elements: Patient history, physical exam findings, imaging results
  • Specific coding terminology: Splenomegaly, underlying conditions (e.g., hematologic disorders)
  • Documentation examples: 'Patient presents with splenomegaly confirmed by ultrasound.'

Coding Guidelines

Usage Guidelines & Examples

  • Usage guidelines: Use R16.0 for isolated splenomegaly; consider underlying conditions for additional codes.
  • Common errors: Failing to document the cause of splenomegaly.

Code Exclusions

Important Exclusions

  • Excluded conditions: Splenic rupture, splenic abscess
