Cellulitis and abscess of oral soft tissues

This code signifies an acute bacterial infection affecting the soft tissues within the oral cavity, such as the buccal mucosa, floor of the mouth, or palate. It encompasses both diffuse inflammation (cellulitis) and localized collections of pus (abscesses) originating from these sites.

Apply this code when documentation clearly indicates an infection like Ludwig's angina, perimandibular cellulitis, or an abscess of the oral mucosa. Supporting documentation should detail the location of the infection within the oral soft tissues and confirm the presence of cellulitis or abscess formation.

• Differentiate from dental abscesses (e.g., periapical, periodontal), which have distinct codes.
• Consider an additional code for the underlying cause if known, such as a dental caries or trauma.
• Ensure the documentation specifies "oral soft tissues" to avoid confusion with infections of other head and neck sites.
