About H34.833

H34.833 is the ICD-10-CM diagnosis code for tributary (branch) retinal vein occlusion, bilateral. It belongs to category H34 (retinal vascular occlusions), block H30-H36 (disorders of choroid and retina) 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 H34.83 (tributary (branch) retinal vein occlusion), H34.833 is specifically for tributary (branch) retinal vein occlusion, bilateral. Related codes cover right eye (H34.831), left eye (H34.832) and unspecified eye (H34.839).

Codes in this range require a 7th character: 0 for with macular edema, 1 for with retinal neovascularization and 2 for stable. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
