Perifolliculitis capitis abscedens

This code represents a severe, chronic inflammatory condition affecting the scalp, characterized by deep-seated pustules, abscesses, and sinus tracts that can lead to scarring alopecia. It is a rare form of folliculitis that primarily affects the hair follicles of the scalp.

Apply this code when documentation clearly indicates a diagnosis of perifolliculitis capitis abscedens, also known as dissecting cellulitis of the scalp or dissecting folliculitis. This diagnosis should be supported by clinical findings of inflammatory nodules, abscesses, and scarring on the scalp.

• Differentiate from other forms of folliculitis or scalp infections; this condition is distinct due to its chronic, deep, and scarring nature.
• Ensure documentation specifies "capitis abscedens" or "dissecting cellulitis of the scalp" to support this specific code.
• Consider co-occurring conditions like acne conglobata or hidradenitis suppurativa, as these can sometimes be seen in conjunction with this disorder.
