ICD-10 Code H16.262 – Vernal keratoconjunctivitis, with limbar and corneal involvement, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.262 – Vernal keratoconjunctivitis, with limbar and corneal involvement, left eye
What it is
This code identifies vernal keratoconjunctivitis affecting the left eye, with inflammation involving both the limbus and cornea. Use it when documentation specifies left-sided disease with corneal and limbal involvement.
Clinical signs
Typical findings include itching, redness, tearing, and light sensitivity, with signs of limbal and corneal inflammation. Clinical features vary; refer to documentation.
When to use this code
Use H16.262 when the provider documents vernal keratoconjunctivitis in the left eye and notes limbar and corneal involvement. This is appropriate for ophthalmology visits, follow-up care, or problem lists when the laterality and extent are clearly stated. Check documentation if the record only says “vernal conjunctivitis” or does not specify the eye.
Do not use for
Do not use this code for right eye, bilateral disease, or cases without corneal or limbal involvement. If the chart does not clearly identify laterality, check documentation.
Coding tip
Confirm both laterality and the corneal/limbal component before assigning H16.262.
