Code Description

ICD-10 D73.4 is a billable code used to indicate a diagnosis of cyst of spleen.

Key Diagnostic Point:

A cyst of the spleen is a fluid-filled sac that can develop within the spleen, often discovered incidentally during imaging studies for other conditions. These cysts can be classified as either true cysts, which are lined by epithelium, or pseudocysts, which lack an epithelial lining. While many splenic cysts are asymptomatic and do not require treatment, some may cause symptoms such as abdominal pain, splenomegaly, or complications like rupture. The presence of a splenic cyst can be associated with various hematological conditions, including neutropenia and other white blood cell disorders, as the spleen plays a crucial role in filtering blood and managing immune responses. In cases where the cyst is symptomatic or there is concern for malignancy, surgical intervention may be necessary. Accurate diagnosis typically involves imaging studies such as ultrasound or CT scans, and the management approach may vary based on the size and symptoms associated with the cyst.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between true cysts and pseudocysts
  • Potential association with other hematological disorders
  • Need for imaging studies to confirm diagnosis
  • Variability in treatment approaches based on symptoms

Audit Risk Factors

  • Inadequate documentation of imaging studies
  • Failure to specify the type of cyst
  • Lack of clinical correlation with symptoms
  • Misclassification of cysts as tumors
