Actinomycotic infection of other specified sites

This code signifies an actinomycotic infection affecting a specific anatomical location not otherwise classified. Actinomycosis is a chronic bacterial infection caused by Actinomyces species, often characterized by abscess formation, tissue fibrosis, and draining sinuses. This particular code is used when the infection is identified in a site other than those explicitly listed in more specific actinomycosis codes.

Apply this code when documentation confirms actinomycosis in a site such as the abdominal wall, musculoskeletal system (excluding bone-specific codes), or other soft tissues not covered by more precise codes. The medical record should clearly state the diagnosis of actinomycosis and specify the affected "other" site.

• Ensure the documentation explicitly states "actinomycosis" and the specific affected site.
• Differentiate from Nocardiosis, which is a similar but distinct bacterial infection.
• Always sequence this code after the primary manifestation or complication if applicable, unless it is the primary reason for the encounter.
