ICD-10 Code H33.113 – Cyst of ora serrata, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.113 – Cyst of ora serrata, bilateral
What it is
H33.113 identifies cysts of the ora serrata in both eyes. This code describes a bilateral retinal peripheral finding, not a detached retina or an acute injury.
Clinical signs
Clinical features vary; refer to documentation. Findings may be recorded on ocular examination or retinal imaging as bilateral ora serrata cysts, often noted incidentally during eye evaluation.
When to use this code
Use this code when the clinician documents cysts of the ora serrata in both eyes. It is appropriate when the diagnosis is confirmed on exam, imaging, or specialist assessment. Code the documented bilateral condition rather than a nonspecific retinal finding.
Do not use for
Do not use this code for retinal detachment, tears, or other peripheral retinal disorders unless specifically documented. If laterality is not bilateral or the record is unclear, check documentation.
Coding tip
Verify that the provider explicitly states “bilateral” before assigning H33.113.
