ICD-10 Code H18.011 – Anterior corneal pigmentations, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.011 – Anterior corneal pigmentations, right eye
What it is
This code identifies pigment deposits on the front surface of the cornea in the right eye. Use it when documentation specifically states anterior corneal pigmentation and laterality is right.
Clinical signs
Findings may include visible corneal pigmentation on slit-lamp exam and an ophthalmology note describing the anterior corneal surface. Clinical features vary; refer to documentation.
When to use this code
Use H18.011 when the provider documents anterior corneal pigmentations limited to the right eye. It is appropriate for ophthalmic assessment notes, problem lists, or follow-up visits that confirm this exact laterality. If the record only says corneal pigmentation without location or eye, check documentation.
Do not use for
Do not use this code for pigmentation in the left eye, both eyes, or unspecified eye. Do not assign it when the chart describes a different corneal disorder or the location of the pigmentation is unclear.
Coding tip
Verify the eye and the exact corneal location in the ophthalmology note before assigning H18.011.
