ICD-10 Code H04.12 – Dry eye syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.12 – Dry eye syndrome
What it is
H04.12 identifies dry eye syndrome, a condition where the eyes do not maintain a healthy tear film. It is used when decreased tear production or excessive tear evaporation causes ocular dryness.
Clinical signs
Typical findings include burning, foreign-body sensation, redness, tearing, and blurred vision that improves with blinking. Clinical features vary; refer to documentation.
When to use this code
Use H04.12 when the clinician documents dry eye syndrome, keratoconjunctivitis sicca, or similar terminology. Apply it when the record supports a diagnosis of chronic ocular dryness rather than a temporary irritation. Check documentation if the cause is specified.
Do not use for
Do not use this code for nonspecific eye redness, allergic conjunctivitis, or simple irritation without a documented dry eye diagnosis. Do not substitute it for another tear or eyelid disorder unless the provider states dry eye syndrome.
Coding tip
Confirm the exact provider wording and any documented underlying cause before assigning H04.12.
