ICD-10 Code H33.112 – Cyst of ora serrata, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.112 – Cyst of ora serrata, left eye
What it is
H33.112 identifies a cyst of the ora serrata in the left eye. This is a localized retinal finding at the eye’s peripheral margin, documented specifically on the left side.
Clinical signs
Clinical features vary; refer to documentation. The diagnosis is usually based on ophthalmic examination and may be noted as an incidental retinal cyst at the ora serrata.
When to use this code
Use H33.112 when the provider documents a cyst of the ora serrata in the left eye. Code it when the record clearly identifies the side and the lesion is not described as another retinal disorder.
If the note only says “retinal cyst” or does not specify laterality, check documentation before assigning this code. You should avoid guessing the anatomic location or eye side.
Do not use for
Do not use this code for cysts in the right eye, bilateral disease, or unspecified eye laterality. Check documentation if the finding is actually a different retinal lesion or a broader retinal detachment-related condition.
Coding tip
Confirm both the exact anatomic term “ora serrata” and the left eye before coding; laterality matters here.
