ICD-10 Code H18.069 – Stromal corneal pigmentations, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.069 – Stromal corneal pigmentations, unspecified eye
What it is
This code identifies pigment deposits within the corneal stroma of an unspecified eye. Use it when the record describes stromal corneal pigmentation but does not name a specific cause or eye.
Clinical signs
Findings may include visible corneal discoloration or pigment seen on slit-lamp examination. Clinical features vary; refer to documentation for the exact appearance, laterality, and any associated corneal disorder.
When to use this code
Use H18.069 when the provider documents stromal corneal pigmentations and the eye is not specified. It also fits cases where the note confirms corneal stromal pigment but does not identify a more precise diagnosis. If the chart names a different corneal condition or a specific eye, code that instead.
Do not use for
Do not use this code for pigment changes limited to other parts of the eye or for corneal findings with a documented specific cause. Check documentation if the record describes a different corneal opacity, deposit, or laterality.
Coding tip
Confirm that “stromal” and “unspecified eye” are both documented before assigning H18.069.
