Acute lymphadenitis of upper limb
ICD-10 L04.2 is a billable code used to indicate a diagnosis of acute lymphadenitis of upper limb.
Acute lymphadenitis of the upper limb is an inflammatory condition characterized by the swelling and tenderness of lymph nodes in the axillary or brachial regions, often due to infection. The condition typically arises from bacterial infections, such as staphylococcal or streptococcal infections, which can originate from skin wounds, insect bites, or systemic infections. Clinically, patients may present with localized pain, erythema, and warmth over the affected area, along with systemic symptoms like fever and malaise. The anatomy involved includes the lymphatic system, particularly the lymph nodes and associated vessels in the upper limb. Disease progression can lead to abscess formation if not treated promptly, necessitating surgical intervention in severe cases. Diagnostic considerations include physical examination, imaging studies (like ultrasound), and laboratory tests to identify the causative organism. Accurate diagnosis is crucial for effective treatment, which may involve antibiotics and, in some cases, drainage of abscesses.

L04.2 specifically covers acute lymphadenitis of the upper limb, which may be due to localized infections, systemic infections, or complications from skin conditions. It does not include chronic lymphadenitis or lymphadenopathy due to malignancies.
L04.2 should be used when there is a clear diagnosis of acute lymphadenitis localized to the upper limb, particularly when accompanied by signs of infection. Related codes may be more appropriate for generalized lymphadenopathy or lymphadenitis in other regions.
Documentation should include a thorough clinical evaluation, details of the patient's symptoms, laboratory results confirming infection, and any imaging studies performed. Notes should also reflect the treatment plan and response to therapy.
