Actinomycosis, unspecified

This code represents an infection caused by Actinomyces bacteria, characterized by chronic, suppurative, and granulomatous inflammation that can affect various body sites. It often presents with abscess formation, tissue fibrosis, and draining sinuses. The "unspecified" nature indicates that the specific anatomical site of the infection is not documented.

Use this code when the medical record clearly indicates a diagnosis of actinomycosis, but the documentation does not specify the primary site of infection (e.g., cervicofacial, thoracic, abdominal, pelvic). This code is appropriate when the physician has diagnosed actinomycosis but further site-specific details are unavailable or not yet determined.

• Avoid using this code if a more specific anatomical site of actinomycosis is documented; always strive for the highest level of specificity.
• Review the entire medical record for any mention of the affected body system or organ to identify a more precise code.
• Query the provider if the documentation is ambiguous regarding the infection site, as more specific codes exist (e.g., A42.0-A42.8).
