H34Retinal vascular occlusions

Non-billable headerICD-10-CM

H34 is a non-billable header ICD-10-CM code for retinal vascular occlusions. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Other codes that can never be billed with H34

These codes carry an Excludes1 note pointing at H34. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H34 alone.

  • G45Transient cerebral ischemic attacks and related syndromes
  • H53.12Transient visual loss

Risk adjustment

H34 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead H34

5 child codes. Green means billable.
