Cyst of spleen

This code signifies the presence of a fluid-filled sac or lesion within the splenic parenchyma. These cysts can be congenital, post-traumatic, parasitic, or neoplastic in origin, often discovered incidentally during imaging studies.

Apply this code when documentation clearly identifies a splenic cyst, regardless of its etiology (e.g., simple cyst, epidermoid cyst, post-traumatic cyst). Supporting documentation typically includes imaging reports (ultrasound, CT, MRI) or pathology reports confirming the diagnosis.

• Do not use this code for splenic abscesses or hematomas; these have distinct codes.
• If the cyst is due to a parasitic infection (e.g., echinococcosis), code the parasitic disease first, followed by this code.
• Ensure the documentation specifies "cyst" and not just a "lesion" if the nature of the lesion is unknown.
