ICD-10 Code H01.84 – Other specified inflammation of left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H01.84 – Other specified inflammation of left upper eyelid
What it is
This code identifies inflammation limited to the left upper eyelid when the condition does not fit a more specific eyelid diagnosis. Use it for documented inflammatory changes of that eyelid only.
Clinical signs
Typical findings may include eyelid redness, swelling, tenderness, or irritation. Clinical features vary; refer to documentation, especially when the note describes a nonspecific inflammatory eyelid disorder.
When to use this code
Use H01.84 when the provider documents inflammation of the left upper eyelid and does not name a more specific condition. It may fit cases described as nonspecific, other specified, or not otherwise classified inflammation. Check documentation for laterality and exact eyelid location before coding.
Do not use for
Do not use this code for inflammation of the right eyelid, both eyelids, or the lower eyelid. Also avoid it when the record supports a more specific diagnosis, such as a clearly named eyelid disorder.
Coding tip
Confirm both laterality and eyelid location in the note; if either is missing or unclear, check documentation before assigning H01.84.
