Folliculitis ulerythematosa reticulata
ICD-10 L66.4 is a billable code used to indicate a diagnosis of folliculitis ulerythematosa reticulata.
Folliculitis ulerythematosa reticulata is a chronic inflammatory skin condition characterized by the presence of follicular papules and plaques, primarily affecting the face, neck, and upper trunk. It is often associated with a history of folliculitis or acneiform eruptions. The condition arises from the inflammation of hair follicles, leading to the formation of keratin plugs and subsequent scarring. Clinically, patients may present with skin changes that include erythematous papules, hyperpigmentation, and a reticular pattern of scarring. The condition can progress over time, leading to significant cosmetic concerns and psychological distress. Diagnosis is typically made through clinical examination, and in some cases, a biopsy may be performed to rule out other conditions such as acne vulgaris or other follicular disorders. Differential diagnoses include other forms of folliculitis, such as bacterial or fungal infections, and conditions like lichen planus. Treatment options may include topical retinoids, corticosteroids, and other anti-inflammatory agents, but management can be challenging due to the chronic nature of the disease.

L66.4 specifically covers folliculitis ulerythematosa reticulata, which is characterized by chronic follicular inflammation and scarring. It is important to differentiate this from other forms of folliculitis and skin disorders that may present similarly.
L66.4 should be used when the clinical presentation aligns with folliculitis ulerythematosa reticulata, particularly when there is a chronic inflammatory process with scarring. It is distinct from acute folliculitis or other non-scarring follicular conditions.
Documentation should include a detailed clinical history, description of the lesions, treatment history, and any diagnostic tests performed. A biopsy report may also be beneficial to confirm the diagnosis and rule out other conditions.
