A42.2

What This Code Means

Cervicofacial actinomycosis is a bacterial infection caused by Actinomyces that affects the neck and face area, often developing after dental procedures or jaw injuries. It typically causes swelling, drainage, and sinus tracts in the affected region.

Coding Tips

• •This code is specific to actinomycosis affecting the cervicofacial region; do not use for actinomycosis in other body sites (thoracic, abdominal, or CNS), which have separate codes
• •Ensure documentation clearly indicates the cervicofacial location and confirms actinomycosis diagnosis, as this is a rare infection that requires specific identification
