ICD-10 Code H17.0 – Adherent leukoma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H17.0 – Adherent leukoma
What it is
Adherent leukoma is a dense corneal scar that has become stuck to the iris after a severe eye injury or ulcer. It usually reflects prior damage to the cornea and may distort vision.
Clinical signs
You may see a white or gray corneal opacity with iris tissue attached to the scar. Clinical features vary; refer to documentation for the extent of corneal involvement and any associated visual impairment.
When to use this code
Use H17.0 when the record specifically documents adherent leukoma or a corneal scar adherent to the iris. This code fits sequelae of corneal trauma, infection, or ulceration when the adhesion is the diagnosed condition. Check documentation if the note only says corneal scar without adhesion.
Do not use for
Do not use this code for uncomplicated corneal opacity, inactive scar without iris adhesion, or general visual loss without a documented adherent leukoma. If the diagnosis is unclear, check documentation.
Coding tip
Assign H17.0 only when the provider links the corneal scar to iris adhesion, not for a nonspecific corneal opacity.
