Other lichen planopilaris

This code represents a chronic inflammatory scalp condition characterized by follicular hyperkeratosis, perifollicular erythema, and progressive scarring alopecia, not otherwise specified as frontal fibrosing alopecia or Graham-Little syndrome. It is a variant of lichen planus that specifically affects hair follicles, leading to permanent hair loss.

Use this code for documented cases of lichen planopilaris that do not fit the criteria for frontal fibrosing alopecia (L66.3) or Graham-Little syndrome (L66.2). Documentation should clearly indicate the diagnosis of lichen planopilaris and specify that it is not one of the more specific subtypes.

• Ensure the physician's documentation explicitly states "lichen planopilaris" and rules out frontal fibrosing alopecia or Graham-Little syndrome.
• Do not use this code if a more specific subtype of lichen planopilaris is documented.
• Consider any associated symptoms or complications, such as pruritus or pain, for additional coding if documented.
