H33.191
BillableOther retinoschisis and retinal cysts, right eye
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This condition involves abnormal splitting or separation of layers within the retina (the light-sensitive tissue at the back of the eye) or the formation of fluid-filled sacs in the retina of the right eye. These changes can affect vision depending on their location and severity.
Coding Tips
- •Verify laterality is documented as right eye only; if bilateral, use separate codes for each eye (H33.192 for left eye)
- •Distinguish between retinoschisis (layer separation) and retinal cysts (fluid-filled cavities) in the documentation, as this affects clinical management and monitoring
