H34 — Retinal vascular occlusions
Not billable
Is H34 billable?
No — H34 is a non-billable header code. H34 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 45 billable codes beneath H34.

Excludes1 — never code together
The conditions below can never be reported together with H34 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- amaurosis fugax (G45.3)
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H34, but a patient may have both at the same time. When documentation supports it, H34 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury (trauma) of eye and orbit (S05.-)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
- syphilis related eye disorders (A50.01, A50.3-, A51.43, A52.71)
What codes fall under H34? (5)
How long has H34 existed?
H34 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with H34?
ICD-10-CM declares these codes mutually exclusive with H34 — exactly one of each pair can be correct for a given encounter.
