H34 is a non-billable ICD-10-CM category code for retinal vascular occlusions, so it cannot be submitted on claims. Use a more specific code from this category instead, such as H34.00, H34.01, H34.02, and H34.03.

Specific Coding for Retinal vascular occlusionsOverview

Non-specific codes like H34 require more characters. Use one of these billable codes instead:

  • H34.0 for Transient retinal artery occlusion

  • Use H34.00 for Transient retinal artery occlusion, unspecified eye

  • Use H34.01 for Transient retinal artery occlusion, right eye

  • Use H34.02 for Transient retinal artery occlusion, left eye

  • Use H34.03 for Transient retinal artery occlusion, bilateral

  • H34.1 for Central retinal artery occlusion

  • Use H34.10 for Central retinal artery occlusion, unspecified eye

  • Use H34.11 for Central retinal artery occlusion, right eye

  • Use H34.12 for Central retinal artery occlusion, left eye

  • Use H34.13 for Central retinal artery occlusion, bilateral

  • H34.2 for Other retinal artery occlusions

  • H34.21 for Partial retinal artery occlusion

  • H34.23 for Retinal artery branch occlusion

  • H34.8 for Other retinal vascular occlusions

  • H34.81 for Central retinal vein occlusion

  • H34.82 for Venous engorgement

  • H34.83 for Tributary (branch) retinal vein occlusion

  • Use H34.9 for Unspecified retinal vascular occlusion

Retinal Disorders

The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. In the center of this nerve tissue is the macula. It provides the sharp, central vision needed for reading, driving and seeing fine detail.

Questions About H34Overview

Is H34 (Retinal vascular occlusions) a billable code?

No. This is a category header that groups the codes for retinal vascular occlusions, and headers cannot be submitted on claims. Claims for retinal vascular occlusions need a more specific code from this category, such as H34.00, H34.01, and H34.02.
