ICD-10 Code H01.89 – Other specified inflammation of unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.89 – Other specified inflammation of unspecified eye, unspecified eyelid
What it is
This code identifies an inflammatory condition affecting the eye or eyelid when the documentation does not name a more specific disorder. Use it for a stated “other specified” inflammation that is not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include redness, swelling, irritation, or tenderness involving the eye or eyelid, but you should code only what is specifically documented.
When to use this code
Use H01.89 when the provider documents a specified inflammatory condition of the eye or eyelid and no more precise ICD-10-CM code applies. It is appropriate when the note distinguishes the condition from routine blepharitis, conjunctivitis, or other named diagnoses. If the laterality or exact structure is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for common, better-defined eye or eyelid inflammations that have their own codes. If the record only says “eye irritation” or “eyelid redness” without a documented inflammatory diagnosis, check documentation.
Coding tip
Assign H01.89 only when the provider clearly documents an unspecified but specified inflammatory diagnosis, not just symptoms.
