About H53.46

H53.46 is the ICD-10-CM diagnosis code for Homonymous bilateral field defects. It belongs to category H53 (visual disturbances), block H53-H54 (visual disturbances and blindness) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within H53.4 (visual field defects), H53.46 is specifically for Homonymous bilateral field defects. Related codes cover unspecified visual field defects (H53.40), Scotoma involving central area (H53.41), Scotoma of blind spot area (H53.42), Sector or arcuate defects (H53.43), other localized visual field defect (H53.45), Heteronymous bilateral field defects (H53.47) and generalized contraction of visual field (H53.48).

To report this condition, pick the subcode that matches the documentation: H53.461 (right side), H53.462 (left side) and H53.469 (unspecified side).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
