Z83.51Family history of eye disorders

Z83.51 is the ICD-10-CM diagnosis code for family history of eye disorders. It belongs to category Z83 (family history of other specific disorders), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within Z83.5 (family history of eye and ear disorders), Z83.51 is specifically for family history of eye disorders. Related codes cover ear disorders (Z83.52).

To report this condition, pick the subcode that matches the documentation: Z83.511 (glaucoma) and Z83.518 (disorder).

The conditions in its Excludes2 note aren't part of Z83.51, but may be coded alongside it if the patient has both: family history of blindness and visual loss (Z82.1).

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