Abscess of thymus

This code identifies an infection within the thymus gland characterized by a localized collection of pus. This condition is a rare inflammatory process that can impair thymic function and potentially lead to systemic infection.

Assign this code when documentation explicitly states an abscess of the thymus. This diagnosis is typically supported by imaging studies (e.g., CT scan, MRI) showing a fluid collection within the thymus, along with clinical signs of infection such as fever, elevated white blood cell count, and possibly mediastinal pain.

• Ensure documentation clearly specifies "abscess" of the thymus, not just inflammation or enlargement.
• Consider co-reporting with codes for underlying systemic infections or sepsis if present.
• Do not confuse with other thymic disorders like cysts or hyperplasia, which have distinct codes.
