ICD-10 Code H01.86 – Other Specified Inflammation of Left Eye, Unspecified Eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.86 – Other specified inflammation of left eye, unspecified eyelid
What it is
This code identifies a documented inflammatory condition affecting the left eye region when the eyelid is not specified. Use it when the record names an other specified inflammation and does not fit a more exact eyelid diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Typical inflammatory findings may include redness, swelling, irritation, or discomfort involving the left eye area, but you should code only what is clearly recorded.
When to use this code
Use H01.86 when the provider documents other specified inflammation of the left eye and the eyelid is unspecified. It may apply when the note describes an inflammatory process without a more precise subtype. If the laterality, eyelid involvement, or diagnosis is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for generalized eye disorders, conjunctival disease, or conditions with a more specific ICD-10-CM diagnosis. Also avoid it when the record identifies a different eyelid, eye structure, or a nonspecific symptom only.
Coding tip
Confirm that the documentation supports both left-sided involvement and an unspecified eyelid before selecting H01.86.
