Cervicofacial actinomycosis

This code represents a chronic bacterial infection caused by Actinomyces species, specifically affecting the head and neck region. It typically presents as a slowly progressive, indurated mass with abscess formation and draining sinuses, often involving the jaw, neck, or face.

Assign this code when documentation clearly indicates a diagnosis of actinomycosis localized to the cervicofacial area. Supporting documentation should include clinical findings consistent with the infection, and ideally, microbiological confirmation of Actinomyces species from a cervicofacial site.

• Differentiate from other fungal or bacterial infections that may present similarly in the head and neck.
• Ensure the documentation specifies "cervicofacial" involvement; other anatomical sites of actinomycosis have different codes.
• Look for terms like "lumpy jaw," "wooden jaw," or "sulfur granules" in the context of a head/neck infection, which are classic signs.
