ICD-10 Code H02.829 – Cysts of unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.829 – Cysts of unspecified eye, unspecified eyelid
What it is
This code identifies a cyst involving the eyelid or eye region when the exact side and location are not specified. Use it when documentation confirms a cyst but does not provide more detail.
Clinical signs
Findings may include a localized, usually painless eyelid or periocular lump, swelling, or a visible cystic lesion. Clinical features vary; refer to documentation.
When to use this code
Use H02.829 when the record states “cyst” of the eye or eyelid but does not identify the side or a more specific subtype. It also fits cases where the clinician documents an unspecified cystic lesion in this area. If laterality or a more precise diagnosis is available, code that instead.
Do not use for
Do not use this code for chalazion, hordeolum, or other clearly named eyelid disorders. If the cyst is documented elsewhere on the face or a different eye structure, Check documentation.
Coding tip
Query for laterality and exact lesion type before assigning this unspecified code.
