ICD-10 Code H02.864 – Hypertrichosis of left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.864 – Hypertrichosis of left upper eyelid
What it is
H02.864 identifies excess hair growth on the left upper eyelid. Use it when documentation specifically describes hypertrichosis affecting that eyelid.
Clinical signs
Clinical features vary; refer to documentation. You may see visibly increased hair growth on the left upper eyelid, sometimes noted during an eye or skin exam.
When to use this code
Use this code when the provider documents hypertrichosis limited to the left upper eyelid. It is appropriate for a localized finding recorded as a diagnosis, problem, or exam abnormality. If the note does not specify laterality or eyelid location, check documentation.
Do not use for
Do not use this code for generalized excess hair growth, eyebrow hair changes, or hair growth on a different eyelid. If the record only says “excess hair” without location, check documentation.
Coding tip
Match the code to the exact eyelid and side documented; laterality matters here.
