Is H34.0 a billable ICD-10-CM code?

No. H34.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does H34.0 sit in the tabular list?

Diseases of the eye and adnexa (H00-H59), in the block Disorders of choroid and retina (H30-H36).

What cannot be coded together with H34.0?

H34.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above H34.0 (H34) and apply to it just the same.

H34.0

H34.0 — Transient retinal artery occlusion

Non-billable headerICD-10-CM

H34.0 is a non-billable header ICD-10-CM code for transient retinal artery occlusion. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above H34.0

These are not written on H34.0, but they bind it: a note on a category applies to every code beneath it. Billing H34.0 with anything listed here is a denial.

Written on H34 — Retinal vascular occlusions

amaurosis fugax (G45.3)

Other codes that can never be billed with H34.0

These codes carry an Excludes1 note pointing at H34.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H34.0 alone.

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

Risk adjustment

H34.0 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 history

H34.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead H34.0

4 child codes. Green means billable.
