ICD-10 Code H11.8 – Other specified disorders of conjunctiva (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.8 – Other specified disorders of conjunctiva
What it is
H11.8 identifies a conjunctival disorder that does not fit a more specific ICD-10 category. Use it when documentation names an unusual or specified conjunctival condition, but no better code is available.
Clinical signs
Clinical features vary; refer to documentation. Conjunctival findings may include redness, irritation, swelling, or visible surface changes, depending on the underlying disorder.
When to use this code
Use H11.8 when the provider documents a specific conjunctival disorder that is not otherwise classified in the code set. It may apply when the note clearly describes the condition but does not support a more precise conjunctival code. Check documentation if the diagnosis is vague or incomplete.
Do not use for
Do not use this code for conjunctivitis, conjunctival hemorrhage, or other conditions with a dedicated ICD-10 code. If the record supports a more specific diagnosis, code that condition instead.
Coding tip
Query for the exact conjunctival diagnosis when the wording is nonspecific, so you can avoid defaulting to H11.8 unnecessarily.
