H53.423
BillableScotoma of blind spot area, bilateral
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A scotoma is a blind spot or area of vision loss in the eye. This code describes when both eyes have a scotoma (blind spot) specifically in the area of the natural blind spot, which is the normal area where the optic nerve enters the eye.
Coding Tips
- •Verify documentation specifies bilateral (both eyes) involvement; if only one eye is affected, use H53.421 (right eye) or H53.422 (left eye) instead
- •Ensure the scotoma is specifically documented as being in the blind spot area rather than other locations in the visual field, as different anatomical locations have different codes
