Hypertrichosis of right upper eyelid

This code describes an abnormal and excessive growth of hair on the right upper eyelid. This condition, known as hypertrichosis, can range from fine vellus hair to coarse terminal hair, potentially affecting vision or causing irritation. It is distinct from hirsutism, which is typically androgen-dependent.

Use this code when documentation specifically identifies hypertrichosis affecting the right upper eyelid. This diagnosis is supported by physician notes detailing the presence and location of excessive hair growth on this specific anatomical site. It is appropriate for both primary and secondary hypertrichosis.

• Ensure the laterality (right) and specific eyelid (upper) are clearly documented to support this precise code.
• Do not confuse with codes for trichiasis (misdirected eyelashes) or hirsutism (androgen-dependent hair growth).
• If the hypertrichosis affects both upper eyelids, a bilateral code or separate codes for each eye would be necessary.
