Madarosis of left lower eyelid and periocular area

This code signifies the loss of eyelashes (madarosis) specifically affecting the lower eyelid and the surrounding periocular region of the patient's left eye. This condition can be a symptom of various underlying dermatological, systemic, or inflammatory disorders, or it can be drug-induced or traumatic.

Apply this code when documentation clearly indicates madarosis localized to the left lower eyelid and its adjacent periocular area. Supporting documentation should specify the affected eye (left) and the precise location (lower eyelid, periocular area). This code is appropriate for both primary and secondary diagnoses, depending on the clinical context.

• Ensure the documentation specifies "left" eye and "lower" eyelid/periocular area; laterality and specific location are crucial for accurate coding.
• Do not confuse with codes for poliosis (whitening of eyelashes) or trichiasis (misdirected eyelashes).
• Always code any underlying systemic or local condition causing the madarosis, if known and documented, as a primary diagnosis if appropriate, with this code as a secondary diagnosis.
