Other androgenic alopecia

This code represents hair loss primarily caused by androgens, presenting in patterns other than the typical male or female pattern baldness. It encompasses various forms of androgen-related alopecia that do not fit the more specific classifications.

Use this code when documentation specifies androgenic alopecia with an atypical presentation, such as diffuse thinning not conforming to a distinct pattern, or when the specific pattern is not clearly defined as male or female pattern baldness. Supporting documentation should clearly indicate an androgenic etiology for the hair loss.

• Differentiate from L64.0 (androgenic alopecia, unspecified) when a more specific, albeit atypical, androgenic cause is documented.
• Avoid using this code if the documentation clearly indicates male pattern (L64.1) or female pattern (L64.2) androgenic alopecia.
• Ensure the physician's notes explicitly link the hair loss to an androgenic cause to support this diagnosis.
