ICD-10 Code H16.143 – Punctate keratitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.143 – Punctate keratitis, bilateral
What it is
H16.143 identifies punctate keratitis affecting both eyes. It means the corneal surface has multiple small, spot-like areas of inflammation or epithelial injury.
Clinical signs
Typical findings include bilateral eye irritation, foreign-body sensation, redness, tearing, and light sensitivity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents punctate keratitis in both eyes. It fits ophthalmology notes describing bilateral corneal punctate staining or similar bilateral corneal surface disease.
Code it only when laterality is stated as bilateral, or when the clinician’s assessment supports both eyes being involved. Check documentation if the note is vague or only one eye is mentioned.
Do not use for
Do not use H16.143 for unilateral punctate keratitis or for nonspecific keratitis without corneal punctate findings. Do not assume bilateral involvement unless the record supports it.
Coding tip
Verify laterality in the assessment, not just the symptom list, before assigning H16.143.
