2025 ICD-10-CM code A42.7

Actinomycotic sepsis.

Use additional code to identify resistance to antimicrobial drugs (Z16.-).

Medical necessity for treatment of actinomycotic sepsis stems from the life-threatening nature of the infection. Prompt diagnosis and treatment are crucial to prevent serious complications and potentially fatal outcomes.

Physicians diagnose actinomycotic sepsis based on patient symptoms, history, physical examination, blood tests (elevated erythrocyte sedimentation rate, C-reactive protein, alkaline phosphatase), and laboratory tests (culture and staining of sputum, drained fluid, or biopsy). Treatment may involve intravenous antibiotics (penicillin, tetracycline, doxycycline, clindamycin, erythromycin), surgical drainage of lesions or abscesses, and patient education on oral hygiene.

In simple words: Actinomycotic sepsis is a serious blood infection caused by bacteria typically found in the mouth and throat. It can lead to fever, pain, sores, and swelling, especially on the chest wall and face/neck. If left untreated, it can be fatal.

Actinomycotic sepsis is a severe infection that occurs when the bacterium Actinomyces israelii enters the bloodstream.

Example 1: A patient presents with fever, chest pain, and draining sores on the chest wall. Blood cultures reveal Actinomyces israelii, confirming actinomycotic sepsis. , Following a dental procedure, a patient develops a persistent fever and swelling in the neck. After further investigation, actinomycotic sepsis is diagnosed., A patient with poor oral hygiene experiences weight loss, fatigue, and multiple draining abscesses. Lab tests confirm the presence of Actinomyces israelii in the bloodstream, indicating actinomycotic sepsis.

Documentation should include evidence of infection (e.g., positive blood culture for Actinomyces israelii), clinical findings (e.g., fever, pain, swelling, sores), and treatment provided (e.g., antibiotics, surgical drainage).
