Lymphadenitis, acute, primary
ICD-10 A28.0 is a billable code used to indicate a diagnosis of lymphadenitis, acute, primary.
Acute primary lymphadenitis is an inflammatory condition characterized by the swelling and tenderness of lymph nodes, typically resulting from an infection. This condition can arise from various infectious agents, including bacteria, viruses, and, in some cases, zoonotic pathogens. Zoonotic infections, which are transmitted from animals to humans, can lead to acute lymphadenitis when pathogens such as Bartonella henselae (cat scratch fever) or Francisella tularensis (tularemia) invade the lymphatic system. The clinical presentation often includes fever, localized pain, and swollen lymph nodes, which may be palpable on examination. Diagnosis is primarily clinical, supported by laboratory tests to identify the causative organism. Treatment typically involves antibiotics, and in some cases, drainage of abscesses may be necessary. Public health considerations are crucial, especially in areas where zoonotic diseases are prevalent, necessitating awareness and preventive measures to reduce transmission risks.
Detailed history of exposure, laboratory results, and treatment plans.
Patients presenting with swollen lymph nodes after animal exposure or recent travel.
Ensure documentation includes specific zoonotic infections and their management.
Comprehensive patient history, including recent infections and travel history.
Patients with acute febrile illness and lymphadenopathy.
Documenting the timeline of symptoms and any potential zoonotic exposures.
Used when an abscess forms in the lymph node area.
Document the size, location, and characteristics of the abscess.
Infectious disease specialists may need to provide additional context for the procedure.
Common causes include bacterial infections from zoonotic sources, such as cat scratch fever and tularemia, as well as viral infections.
