ICD-10 Code H33.339 – Multiple defects of retina without detachment, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.339 – Multiple defects of retina without detachment, unspecified eye
What it is
This code identifies multiple retinal breaks or defects in an eye, with no retinal detachment documented. Use it when the chart confirms more than one retinal defect but does not specify the eye.
Clinical signs
Clinical features vary; refer to documentation. Patients may be noted to have retinal tears, holes, or lattice-related defects on ophthalmic exam, usually without evidence of detachment.
When to use this code
Use H33.339 when the provider documents multiple retinal defects and explicitly states there is no detachment. It also fits when the eye is not identified in the record. If laterality is documented, code the specified eye instead.
Do not use for
Do not use this code for retinal detachment, even if a defect is present. Do not use it when only a single retinal defect is documented or when another more specific retinal disorder is named.
Coding tip
Check the ophthalmology note for laterality and for any mention of detachment before assigning this unspecified-eye code.
