Splenomegaly

This code represents an enlargement of the spleen, a condition known as splenomegaly. The spleen, an organ in the upper left abdomen, can become enlarged due to various underlying medical conditions affecting the blood, liver, or immune system.

Use this code when documentation explicitly states "splenomegaly" or describes an enlarged spleen identified during physical examination, imaging studies (e.g., ultrasound, CT scan), or surgical exploration. This code is often used as a secondary diagnosis, indicating a manifestation of another primary disease.

• Always code the underlying cause of the splenomegaly first, if known and documented.
• Do not use this code if the enlargement is due to a normal variant or a temporary, non-pathological condition.
• Ensure the medical record clearly supports the diagnosis of splenomegaly, not just a palpable spleen.
