Madarosis of left upper eyelid and periocular area

This code signifies the loss of eyelashes (madarosis) specifically affecting the upper eyelid and the surrounding periocular region of the patient's left eye. This condition can be a symptom of various underlying dermatological, autoimmune, or systemic diseases, or a side effect of certain treatments.

Apply this code when documentation clearly indicates madarosis localized to the left upper eyelid and its adjacent periocular area. This is appropriate for conditions such as alopecia areata affecting the eyelid, cicatricial alopecia, or drug-induced eyelash loss in the specified location. Physician notes detailing the exact location of eyelash loss are crucial.

• Differentiate from other forms of madarosis (e.g., poliosis, trichiasis) which have distinct codes.
• Ensure laterality is accurately documented and coded; this code is specific to the left side.
• Always code the underlying cause of the madarosis, if known, as a primary diagnosis when applicable.
