ICD-10 Code H33.331 – Multiple defects of retina without detachment, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.331 – Multiple defects of retina without detachment, right eye
What it is
This code identifies multiple retinal breaks or defects in the right eye when the retina is still attached. Use it for documented retinal lesions that do not include detachment.
Clinical signs
Clinical features vary; refer to documentation. Findings may include retinal tears or holes seen on ophthalmic examination, sometimes with flashes, floaters, or incidental detection during retinal evaluation.
When to use this code
Use H33.331 when the record clearly states multiple defects of the retina in the right eye and there is no retinal detachment. It is appropriate for ophthalmology notes, exam findings, or imaging reports that specify the right eye. Check documentation if laterality or detachment status is unclear.
Do not use for
Do not use this code for retinal detachment, even if defects are present. Do not use it when the defects are in the left eye, both eyes, or when the chart does not specify the right eye.
Coding tip
Confirm both laterality and absence of detachment before assigning H33.331.
