Abscess of thymus

This code represents an acute or chronic localized collection of pus within the thymus gland, typically resulting from a bacterial infection. It signifies an inflammatory process leading to tissue destruction and purulent exudate formation within this primary lymphoid organ.

Use this code when documentation explicitly states "abscess of thymus" or "thymic abscess." Supporting clinical findings may include imaging (e.g., CT scan showing a fluid collection in the thymus), laboratory results indicating infection, and surgical pathology confirming an abscess.

• Ensure documentation clearly specifies the thymus as the affected organ, not adjacent structures.
• Do not confuse with other thymic conditions like cysts or tumors; an abscess implies infection.
• Consider an additional code for the causative organism if identified and documented.
