ICD-10 Code H11.143 – Conjunctival xerosis, unspecified, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.143 – Conjunctival xerosis, unspecified, bilateral
What it is
This code identifies dryness of the conjunctiva in both eyes, with no further detail documented. It indicates a bilateral conjunctival surface change rather than a specific cause.
Clinical signs
Clinical features may include conjunctival dryness, a dull or rough ocular surface, and irritation. Clinical features vary; refer to documentation.
When to use this code
Use H11.143 when the provider documents conjunctival xerosis affecting both eyes and does not specify a cause or more precise subtype. It is appropriate for charted bilateral conjunctival dryness, including when the record states “unspecified” or provides limited detail. Check documentation if laterality or etiology is unclear.
Do not use for
Do not use this code for corneal dryness, dry eye syndrome, or conjunctival disorders with a documented specific cause. If the record identifies a different conjunctival condition, code that diagnosis instead.
Coding tip
Confirm both laterality and the exact wording “conjunctival xerosis” before assigning H11.143.
