Acute lymphadenitis, unspecified
ICD-10 L04.9 is a billable code used to indicate a diagnosis of acute lymphadenitis, unspecified.
Acute lymphadenitis, unspecified, is characterized by the inflammation of lymph nodes, which can occur due to various infectious agents, including bacteria, viruses, or fungi. Clinically, patients may present with swollen, tender lymph nodes, often accompanied by systemic symptoms such as fever, malaise, and localized pain. The lymphatic system, comprising lymph nodes and vessels, plays a crucial role in immune response and fluid balance. Acute lymphadenitis can progress rapidly, leading to complications such as abscess formation if not treated promptly. Diagnostic considerations include a thorough clinical history, physical examination, and, when necessary, imaging studies or laboratory tests to identify the underlying cause. Differential diagnoses may include other forms of lymphadenopathy, such as reactive hyperplasia or malignancy, necessitating careful evaluation to ensure appropriate management.

L04.9 covers acute lymphadenitis without specifying the cause or location. It may include infections from common pathogens like Staphylococcus aureus or Streptococcus species, but does not detail specific infectious agents.
L04.9 should be used when acute lymphadenitis is diagnosed but the specific site or cause is not identified. If the lymphadenitis is localized or due to a specific infection, more specific codes should be utilized.
Documentation should include clinical findings such as the location of lymphadenopathy, associated symptoms, and any diagnostic tests performed. A clear rationale for the acute diagnosis is essential.
