ICD-10 Code H16.293 – Other keratoconjunctivitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.293 – Other keratoconjunctivitis, bilateral
What it is
H16.293 identifies keratoconjunctivitis affecting both eyes when the record does not specify a more exact type. It means inflammation involves the cornea and conjunctiva on both sides.
Clinical signs
Typical findings include bilateral eye redness, irritation, tearing, foreign-body sensation, and light sensitivity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents other keratoconjunctivitis in both eyes and does not name a more specific subtype. It is appropriate for charted bilateral corneal and conjunctival inflammation when laterality is clear. Check documentation if the note only says conjunctivitis, keratitis, or dry eye.
Do not use for
Do not use H16.293 if the condition is unilateral, unspecified, or documented as a different keratoconjunctivitis type. Do not use it for isolated conjunctivitis or keratitis without corneal and conjunctival involvement.
Coding tip
Confirm both the “other” designation and bilateral laterality in the provider note before assigning H16.293.
