ICD-10 Code H18.063 – Stromal corneal pigmentations, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.063 – Stromal corneal pigmentations, bilateral
What it is
H18.063 identifies pigment deposits within the corneal stroma in both eyes. Use it when documentation specifically describes bilateral stromal corneal pigmentation rather than a superficial corneal stain or a different corneal disorder.
Clinical signs
Findings may include visible corneal discoloration on slit-lamp exam and bilateral stromal pigment accumulation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents stromal corneal pigmentations affecting both corneas. It is appropriate for ophthalmology notes, consults, or problem lists that clearly name the bilateral stromal location. If laterality is not documented, check documentation before coding.
Do not use for
Do not use H18.063 for corneal pigmentation limited to one eye or for pigment on the surface layer only. Do not assume the code applies to other corneal opacities or deposits; check documentation.
Coding tip
Confirm both the stromal location and bilateral laterality in the record before assigning H18.063.
