ICD-10 Code H11.149 – Conjunctival xerosis, unspecified, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.149 – Conjunctival xerosis, unspecified, unspecified eye
What it is
Use this code for dryness of the conjunctiva in an unspecified eye when the record does not identify a more specific site or cause. It indicates a dry, less-lubricated conjunctival surface.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include ocular dryness, irritation, and a rough or dull conjunctival appearance, but you should code only what is documented.
When to use this code
Assign H11.149 when the provider documents conjunctival xerosis and does not specify right or left eye. Use it when the note supports dryness of the conjunctiva without a more specific diagnosis or underlying condition.
If the chart later identifies the affected eye or a different conjunctival disorder, update the code accordingly. Check documentation for laterality and any linked systemic cause.
Do not use for
Do not use this code for general dry eye syndrome, corneal xerosis, or conjunctivitis. If the record names a different eye condition or specifies the eye, choose the more accurate code.
Coding tip
Confirm that “conjunctival xerosis” is explicitly documented and that no laterality is provided before selecting this unspecified-eye code.
