ICD-10 Code H11.142 – Conjunctival xerosis, unspecified, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.142 – Conjunctival xerosis, unspecified, left eye
What it is
H11.142 identifies dryness of the conjunctiva in the left eye. It is used when the chart documents conjunctival xerosis but does not specify a more detailed cause.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the conjunctiva appears dry, dull, or less lustrous, and the patient may report irritation, foreign-body sensation, or redness.
When to use this code
Use this code when the provider documents conjunctival xerosis affecting the left eye and does not name another specific conjunctival disorder. It also fits when the record clearly identifies dryness of the left conjunctiva without a more precise etiology. If the note is vague, check documentation before coding.
Do not use for
Do not use it for corneal dryness, dry eye syndrome, or xerosis of another eye structure unless the documentation specifically supports conjunctival involvement. Check documentation if the laterality or diagnosis is unclear.
Coding tip
Always confirm left-eye laterality and the exact wording in the assessment before assigning H11.142.
