Lichen planopilaris, unspecified

This code describes an inflammatory, chronic autoimmune condition affecting hair follicles, leading to scarring alopecia. It is characterized by perifollicular erythema and scaling, primarily on the scalp, resulting in permanent hair loss. The "unspecified" nature indicates that further details regarding the specific type or extent of lichen planopilaris are not documented.

Use this code when the physician's documentation clearly states a diagnosis of lichen planopilaris but does not specify a particular variant or provide additional descriptive details. This code is appropriate when the clinical presentation aligns with the general characteristics of the condition, and no further specificity is available or required for coding.

• Avoid using this code if the documentation specifies a particular subtype of lichen planopilaris, such as frontal fibrosing alopecia.
• Ensure the medical record supports the diagnosis of lichen planopilaris, even if unspecified, through clinical findings or biopsy results.
• Consider querying the provider for more specific documentation if a subtype is suspected but not explicitly stated.
