ICD-10 Code H11.89 – Other specified disorders of conjunctiva (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.89 – Other specified disorders of conjunctiva
What it is
H11.89 identifies a conjunctival disorder that is specified in the chart but does not have its own more exact ICD-10 code. Use it when the provider documents a distinct conjunctival condition and no other category fits.
Clinical signs
Clinical features vary; refer to documentation. Conjunctival findings may include redness, irritation, swelling, discharge, or visible lesions, but you should code only what the provider specifically describes.
When to use this code
Use H11.89 when the record names an “other specified” conjunctival disorder, such as an unusual inflammatory or structural problem of the conjunctiva. It is also appropriate when the condition is clearly conjunctival but is not indexed to a more specific code. Check documentation if the diagnosis is vague.
Do not use for
Do not use this code for common conjunctival diagnoses that have their own codes, such as conjunctivitis, pterygium, or pinguecula. If the provider does not specify the disorder, you may need a symptom code or further documentation.
Coding tip
Verify that the note says “other specified” or gives a named conjunctival disorder before assigning H11.89.
