ICD-10 Code H33.32 – Round hole of retina without detachment (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.32 – Round hole of retina without detachment
What it is
H33.32 identifies a full-thickness round retinal break that has not progressed to retinal detachment. Use it when the retina is torn or perforated, but the neurosensory retina remains attached.
Clinical signs
Findings may include a visible round retinal hole on dilated fundus examination, sometimes with photopsia or floaters. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a round hole of the retina and specifically states there is no detachment. It also fits follow-up visits after diagnosis when the condition remains present and unchanged. Check documentation if the note mentions a retinal tear, lattice degeneration, or detachment instead.
Do not use for
Do not use H33.32 if the retina is detached or if the documentation describes another retinal break type. If the record is unclear, check documentation.
Coding tip
Confirm the note says “without detachment” before assigning H33.32.
