Anomalies of spleen

This code signifies congenital or acquired structural abnormalities of the spleen. These anomalies can range from complete absence (asplenia) or multiple spleens (polysplenia) to variations in size, shape, or position. It encompasses conditions where the spleen's development or morphology deviates from the norm.

Use this code when documentation indicates a diagnosed congenital splenic anomaly, such as asplenia, polysplenia, or accessory spleen. It is also appropriate for acquired structural abnormalities not otherwise classified, such as splenic cysts or ectopic spleen, when no other more specific code applies. Supporting documentation would include imaging reports (e.g., ultrasound, CT, MRI) or surgical findings.

• Differentiate between congenital anomalies and acquired conditions like splenomegaly due to other diseases.
• Ensure documentation clearly specifies the type of anomaly; if more specific ICD-9 codes exist for a particular anomaly, use those.
• Do not use this code for functional disorders of the spleen without a structural anomaly.
