Other alopecia areata

This code signifies a form of autoimmune hair loss characterized by patchy, non-scarring hair loss that does not fit the descriptions of more specific alopecia areata subtypes. It involves the immune system mistakenly attacking hair follicles, leading to hair shedding from various body sites. The condition can range from small, isolated patches to more extensive involvement.

Use this code when the medical record documents alopecia areata that is not clearly specified as a single patch (L63.0), ophiasis (L63.1), totalis (L63.2), universalis (L63.3), or another defined type. This code is appropriate for cases where the pattern of hair loss is atypical or involves multiple, scattered patches that don't conform to the more specific classifications. Documentation should clearly state "alopecia areata, other specified" or describe a presentation that falls outside the more precise categories.

• Do not use this code if the documentation specifies a single patch of alopecia areata; instead, use L63.0.
• Ensure the provider's documentation clearly indicates that the alopecia areata does not fit into the more specific categories (e.g., totalis, universalis, ophiasis).
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis if it's a co-existing condition being managed.
