ICD-10 Code H33.111 – Cyst of ora serrata, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.111 – Cyst of ora serrata, right eye
What it is
This code identifies a cyst located at the ora serrata in the right eye. It is a specific retinal finding, not a general eye cyst.
Clinical signs
Clinical features vary; refer to documentation. Diagnosis is usually based on ophthalmologic examination and documented localization to the right eye.
When to use this code
Use H33.111 when the provider documents a cyst of the ora serrata in the right eye. Code it when the record clearly identifies the lesion’s site and laterality.
Choose this code for a confirmed right-eye finding, even if it is incidental. If the note is nonspecific about eye or location, check documentation before assigning the code.
Do not use for
Do not use this code for cysts in the left eye, both eyes, or unspecified eye. Do not use it for other retinal disorders unless the ora serrata cyst is specifically documented.
Coding tip
Verify both laterality and anatomic site in the ophthalmology note before coding.
