ICD-10 Code H02.0 – Entropion and trichiasis of eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.0 – Entropion and trichiasis of eyelid
What it is
H02.0 identifies inward turning of the eyelid margin or misdirected eyelashes that rub against the eye. This code covers conditions where the lashes or lid edge contact the globe and cause irritation.
Clinical signs
Typical findings include eyelid inversion, lashes touching the cornea or conjunctiva, tearing, foreign-body sensation, redness, and discomfort. Clinical features vary; refer to documentation.
When to use this code
Use H02.0 when the record documents entropion, trichiasis, or both affecting an eyelid. It is appropriate when the provider diagnoses the lid malposition or misdirected lashes as the reason for eye irritation or exam findings.
If the note specifies a more detailed eyelid condition, code that documented diagnosis instead. Check documentation when the laterality or exact eyelid involvement is unclear.
Do not use for
Do not use H02.0 for general eye redness or irritation without documented entropion or trichiasis. Do not assign it when the eyelid problem is a different disorder, such as ptosis or blepharitis.
Coding tip
Verify the provider’s wording for entropion, trichiasis, or both, and capture laterality only if the record supports it.
