ICD-10 Code H16.141 – Punctate Keratitis, Right Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.141 – Punctate keratitis, right eye
What it is
This code identifies punctate keratitis limited to the right eye. It means the corneal surface has small, scattered epithelial lesions or spots, usually documented on eye examination.
Clinical signs
Typical findings include ocular irritation, redness, foreign-body sensation, tearing, and light sensitivity. Clinical features vary; refer to documentation for the exact cause and extent of corneal involvement.
When to use this code
Use H16.141 when the provider documents punctate keratitis in the right eye only. It is appropriate when the note clearly identifies the right eye and does not describe bilateral disease or a different corneal disorder.
If the record states punctate keratitis without laterality, check documentation before coding. Code the condition based on the documented eye and avoid assuming laterality from exam context alone.
Do not use for
Do not use this code for left eye, bilateral disease, or unspecified punctate keratitis. It is also not appropriate when the documentation describes another corneal condition, such as ulceration or abrasion.
Coding tip
Confirm laterality in the ophthalmology note and code only what is explicitly documented.
