Hypertrichosis of left eye, unspecified eyelid

This code signifies an abnormal or excessive growth of hair on the left eye, specifically on an unspecified eyelid. This condition, known as hypertrichosis, can range from fine vellus hair to coarse terminal hair, and may be congenital or acquired.

Use this code when documentation clearly indicates hypertrichosis affecting the left eye, but the specific eyelid (e.g., upper, lower) is not specified. This code is appropriate for conditions like localized hirsutism or eyelash overgrowth (trichomegaly) when the laterality is known but the precise eyelid is not documented.

• Ensure documentation specifies "left eye" and "unspecified eyelid" for accurate coding.
• Avoid using this code if the specific eyelid (e.g., upper, lower) is documented; more specific codes exist.
• Do not confuse with codes for madarosis (loss of eyelashes) or trichiasis (misdirected eyelashes).
