ICD-10 Code H16.269 – Vernal keratoconjunctivitis, with limbar and corneal involvement, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.269 – Vernal keratoconjunctivitis, with limbar and corneal involvement, unspecified eye
What it is
This code identifies vernal keratoconjunctivitis affecting both the limbus and cornea, but the chart does not specify which eye is involved. It is a chronic allergic eye condition that can cause surface inflammation.
Clinical signs
Typical findings include itching, redness, tearing, and photophobia, with limbal and corneal involvement documented on exam. Clinical features vary; refer to documentation.
When to use this code
Use H16.269 when the provider documents vernal keratoconjunctivitis with both limbal and corneal involvement and does not identify the eye. It is appropriate when the record supports the diagnosis but laterality remains unspecified. Check documentation if the note only says allergic conjunctivitis or keratitis.
Do not use for
Do not use this code for nonspecific conjunctivitis, isolated keratitis, or vernal keratoconjunctivitis without corneal involvement. If the affected eye is documented, select the laterality-specific code instead.
Coding tip
Confirm both the diagnosis detail and laterality in the note before assigning H16.269.
