Acute lymphadenitis of trunk

This code signifies an acute inflammatory process affecting the lymph nodes located in the trunk of the body. This inflammation is typically a response to infection or other localized pathology, presenting with sudden onset of pain, tenderness, and swelling of the affected lymph nodes.

Assign this code when documentation clearly indicates an acute inflammation of lymph nodes within the thoracic, abdominal, or pelvic regions. This diagnosis is supported by findings such as palpable, tender, and enlarged lymph nodes in these areas, often accompanied by systemic signs of infection.

• Differentiate from chronic lymphadenitis, which is coded elsewhere.
• Ensure the documentation specifies "acute" and the "trunk" as the anatomical location.
• If the underlying cause of the lymphadenitis is known (e.g., bacterial infection), sequence the code for the underlying condition first, followed by this code.
