Acute lymphadenitis of lower limb
ICD-10 L04.3 is a billable code used to indicate a diagnosis of acute lymphadenitis of lower limb.
Acute lymphadenitis of the lower limb is characterized by the inflammation of lymph nodes in the groin or popliteal region, often resulting from an infectious process. Clinically, patients may present with localized swelling, tenderness, erythema, and warmth over the affected area, accompanied by systemic symptoms such as fever and malaise. The anatomy involved primarily includes the lymphatic system, particularly the lymph nodes that drain the lower limb. Disease progression can vary; if untreated, acute lymphadenitis may lead to abscess formation or systemic infection. Diagnostic considerations include a thorough clinical examination, imaging studies such as ultrasound to assess lymph node enlargement, and laboratory tests to identify the causative organism, which may include bacterial cultures. Prompt diagnosis and treatment are essential to prevent complications and ensure optimal patient outcomes.

L04.3 specifically covers acute lymphadenitis of the lower limb, which may arise from infections such as cellulitis, abscesses, or systemic infections that spread to lymph nodes. It is important to differentiate it from chronic lymphadenitis and other related conditions.
L04.3 should be used when the lymphadenitis is acute and specifically localized to the lower limb. If the lymphadenitis is due to a different cause or located in another region, appropriate codes such as L04.0 or L04.1 should be selected.
Documentation should include clinical findings such as the presence of swelling, tenderness, and systemic symptoms, as well as results from imaging studies and laboratory tests that confirm the diagnosis of acute lymphadenitis.
