ICD-10 Code H33.033 – Retinal detachment with giant retinal tear, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.033 – Retinal detachment with giant retinal tear, bilateral
What it is
This code identifies retinal detachment in both eyes caused by a giant retinal tear. It means the neurosensory retina has separated from the underlying tissue bilaterally.
Clinical signs
Typical findings include sudden flashes, floaters, a curtain-like shadow, or reduced vision in one or both eyes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states bilateral retinal detachment with a giant retinal tear. It is appropriate for ophthalmology notes, operative reports, or discharge summaries that document both the detachment and the tear.
If laterality is not documented, or the tear type is not specified as giant, check documentation before coding. Do not assume bilateral involvement from a unilateral note.
Do not use for
Do not use this code for retinal detachment without a giant tear, or for a giant retinal tear without detachment. Check documentation if the condition is unilateral or unspecified.
Coding tip
Confirm both elements—bilateral detachment and giant retinal tear—are explicitly documented before assigning H33.033.
