ICD-10 Code H33.322 – Round hole, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.322 – Round hole, left eye
What it is
H33.322 identifies a round retinal hole in the left eye. It describes a full-thickness defect in the retina, usually documented by eye examination.
Clinical signs
Patients may have flashes, floaters, or no symptoms at all. Clinical features vary; refer to documentation, especially findings of a retinal hole in the left eye.
When to use this code
Use this code when the provider documents a round hole specifically in the left retina. It is appropriate for confirmed retinal findings on ophthalmic exam or imaging when the laterality is clearly stated.
Code it only when the record supports the diagnosis, not just symptoms such as flashes or floaters. If the note mentions a retinal tear, detachment, or unspecified hole, check documentation before assigning H33.322.
Do not use for
Do not use this code for right eye or bilateral retinal holes. It is also incorrect for retinal detachment or nonspecific vitreoretinal symptoms without documented left-eye round hole.
Coding tip
Always verify laterality and whether the provider documented a round hole rather than another retinal lesion.
