Madarosis of right upper eyelid and periocular area

This code signifies the loss of eyelashes (madarosis) specifically affecting the right upper eyelid and the surrounding periocular skin. This condition can range from partial thinning to complete absence of lashes, often indicating an underlying dermatological, autoimmune, or systemic issue.

Apply this code when documentation clearly states madarosis of the right upper eyelid and/or the adjacent periocular region. This is appropriate for conditions like alopecia areata, blepharitis, or drug-induced lash loss affecting this specific anatomical site. Ensure the laterality and specific eyelid are explicitly documented.

• Differentiate from trichiasis (misdirected eyelashes) or poliosis (whitening of eyelashes).
• Always confirm laterality (right vs. left) and the specific eyelid (upper vs. lower) from the physician's notes.
• Code any underlying systemic or dermatological condition causing the madarosis as a primary diagnosis, if known and documented.
