ICD-10 Code H02.826 – Cysts of Left Eye, Unspecified Eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.826 – Cysts of left eye, unspecified eyelid
What it is
This code identifies a cyst on the left eyelid when the record does not specify a more exact eyelid location or cyst type. Use it for a documented cyst affecting the left eye’s eyelid area, not the eyeball itself.
Clinical signs
Common findings include a localized, usually round eyelid lump or swelling that may be painless. Clinical features vary; refer to documentation for whether the lesion is inflamed, tender, or causing irritation.
When to use this code
Use H02.826 when the provider documents a cyst of the left eyelid and does not name a more specific eyelid subsite. It also fits when laterality is clear but the cyst is otherwise unspecified. If the note only says “eyelid cyst,” check documentation for side.
Do not use for
Do not use this code for cysts of the right eyelid, bilateral eyelids, or lesions on the eye itself. If the diagnosis is more specific, such as a named eyelid cyst type, code the documented condition instead.
Coding tip
Verify laterality and eyelid location in the note before assigning H02.826.
