Lichen striatus
ICD-10 L44.2 is a billable code used to indicate a diagnosis of lichen striatus.
Lichen striatus is a rare, self-limiting skin condition characterized by linear bands of papules that typically appear on the extremities, particularly the arms and legs. It is believed to be a variant of lichen planus, often presenting in children and young adults. The lesions are usually asymptomatic, but they can occasionally be itchy. The pathophysiology involves an inflammatory response affecting the epidermis and dermis, leading to the characteristic appearance of the skin. Diagnosis is primarily clinical, supported by a thorough history and physical examination. A biopsy may be performed to rule out other conditions, particularly if the presentation is atypical. The disease generally resolves spontaneously within months to a few years, and treatment is often unnecessary unless symptoms are bothersome. In such cases, topical corticosteroids may be used to alleviate discomfort. Understanding the anatomy involved, particularly the skin layers affected, is crucial for accurate diagnosis and management.

L44.2 specifically covers lichen striatus, which is characterized by linear papules on the skin. It is distinct from other lichen conditions such as lichen planus and lichen simplex chronicus.
L44.2 should be used when the clinical presentation matches that of lichen striatus, particularly the linear arrangement of lesions. If the lesions are more generalized or exhibit different characteristics, other codes such as L43 may be more appropriate.
Documentation should include a detailed clinical description of the lesions, their distribution, and any associated symptoms. A biopsy report may be necessary to confirm the diagnosis and rule out other conditions.
