About H34.83

H34.83 is the ICD-10-CM diagnosis code for tributary (branch) retinal vein occlusion. 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 4 subcodes must be used instead.

Within H34.8 (other retinal vascular occlusions), H34.83 is specifically for tributary (branch) retinal vein occlusion. Related codes cover central retinal vein occlusion (H34.81) and venous engorgement (H34.82).

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 hasn't changed since.

7th character

One of the following 7th characters is to be assigned to codes in subcategory H34.83 to designate the severity of the occlusion:

  • 0with macular edema
  • 1with retinal neovascularization
