Perifolliculitis capitis abscedens
ICD-10 L66.3 is a billable code used to indicate a diagnosis of perifolliculitis capitis abscedens.
Perifolliculitis capitis abscedens is a dermatological condition characterized by the inflammation of hair follicles on the scalp, leading to the formation of painful abscesses. Clinically, it presents as tender, erythematous nodules that may rupture, releasing pus. The condition primarily affects adolescents and young adults, particularly males, and is often associated with conditions such as acne or folliculitis. The anatomy involved includes the hair follicles, sebaceous glands, and surrounding dermal tissue. Disease progression can lead to scarring and hair loss if not treated promptly. Diagnostic considerations include a thorough clinical examination, patient history, and, in some cases, culture of the pus to identify any underlying bacterial infection. Differential diagnoses may include other follicular disorders, such as folliculitis or hidradenitis suppurativa. Treatment typically involves antibiotics, drainage of abscesses, and, in chronic cases, surgical intervention may be necessary to prevent recurrence.

L66.3 specifically covers perifolliculitis capitis abscedens, which involves inflammation and abscess formation of hair follicles on the scalp. It is distinct from other follicular conditions such as simple folliculitis or acne vulgaris.
L66.3 should be used when there is clear evidence of abscess formation associated with folliculitis on the scalp. If there is no abscess, consider using L66.2 for simple folliculitis.
Documentation should include clinical findings of abscesses, treatment plans, and any laboratory results, such as cultures, that confirm bacterial infection. Detailed notes on the patient's history and response to treatment are also essential.
