ICD-10 Code H11.44 – Conjunctival cysts (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.44 – Conjunctival cysts
What it is
H11.44 identifies a cyst in the conjunctiva, the thin membrane covering the white of the eye and inner eyelids. It is used when documentation shows a conjunctival cyst rather than another surface eye lesion.
Clinical signs
Clinical features vary; refer to documentation. A conjunctival cyst is typically described as a small, fluid-filled, translucent or clear lesion on the conjunctival surface.
When to use this code
Use H11.44 when the provider documents a conjunctival cyst, including a cyst noted on eye exam or ophthalmology consultation. Apply it when the lesion is specifically identified as conjunctival and not another ocular surface condition. Check documentation if the record is unclear.
Do not use for
Do not use this code for chalazion, stye, or other eyelid masses. Also avoid it when the lesion is documented as a different conjunctival disorder or the diagnosis is uncertain.
Coding tip
Code only when the chart clearly names a conjunctival cyst; if the site or lesion type is vague, query the provider.
