ICD-10 Code H11 – Other disorders of conjunctiva (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11 – Other disorders of conjunctiva
What it is
H11 identifies disorders affecting the conjunctiva that are not classified elsewhere. Use it when documentation describes a conjunctival condition but does not fit a more specific ICD-10-CM code.
Clinical signs
Clinical features vary; refer to documentation. Conjunctival findings may include redness, irritation, swelling, discharge, or visible surface changes, depending on the underlying disorder.
When to use this code
Use H11 when the provider documents an unspecified or other conjunctival disorder and no more specific diagnosis is available. It may also apply when the record confirms conjunctival disease, but the exact subtype is not stated. Review the note carefully before assigning this code.
Do not use for
Do not use H11 if the record identifies a more specific conjunctival diagnosis, such as conjunctivitis or a defined lesion with its own code. Check documentation.
Coding tip
If the chart names a particular conjunctival condition, code that diagnosis instead of the broad H11 category.
