ICD-10 Code H16.292 – Other keratoconjunctivitis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.292 – Other keratoconjunctivitis, left eye
What it is
This code identifies keratoconjunctivitis affecting the left eye when the record does not fit a more specific subtype. It indicates inflammation involving both the cornea and conjunctiva.
Clinical signs
Typical findings may include eye redness, irritation, tearing, foreign-body sensation, and light sensitivity. Clinical features vary; refer to documentation for the exact cause and laterality.
When to use this code
Use H16.292 when the provider documents other keratoconjunctivitis in the left eye and no more specific code applies. It is appropriate when the diagnosis is clearly limited to the left eye and the chart supports corneal and conjunctival inflammation. Check documentation if the type is unspecified or if both eyes are involved.
Do not use for
Do not use this code for keratoconjunctivitis in the right eye, bilateral disease, or a more specific named subtype. If the record only says conjunctivitis or keratitis, code the documented condition instead.
Coding tip
Verify laterality and the exact diagnosis wording before assigning H16.292.
