ICD-10 Code H33.039 – Retinal detachment with giant retinal tear, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.039 – Retinal detachment with giant retinal tear, unspecified eye
What it is
This code identifies a retinal detachment caused by a giant retinal tear, when the affected eye is not specified. It describes a serious separation of the retina from the underlying tissue.
Clinical signs
Typical findings include sudden flashes, new floaters, a curtain-like shadow, and decreased vision. Clinical features vary; refer to documentation, especially for laterality and confirmation of a giant tear.
When to use this code
Use H33.039 when the record documents retinal detachment with a giant retinal tear and does not state whether the right or left eye is involved. You may also use it when the provider confirms the diagnosis but laterality remains unspecified. Check documentation if the note mentions a different retinal detachment type.
Do not use for
Do not use this code for retinal detachment without a giant tear, or when the eye is clearly identified and a laterality-specific code is available. Check documentation for the exact diagnosis.
Coding tip
Verify both the giant retinal tear and unspecified eye before assigning H33.039.
