ICD-10 Code H33.019 – Retinal detachment with single break, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.019 – Retinal detachment with single break, unspecified eye
What it is
This code identifies a retinal detachment caused by one retinal break, when the affected eye is not documented. It tells you the retina has separated from the back of the eye.
Clinical signs
Typical findings include sudden flashes, new floaters, or a curtain-like shadow in vision. Clinical features vary; refer to documentation and the ophthalmology report for the eye involved and the break description.
When to use this code
Use H33.019 when the provider documents retinal detachment with a single break but does not specify right or left eye. It also fits when the record clearly states one retinal break and the laterality remains unspecified. Check documentation if the note mentions multiple breaks, traction, or other retinal detachment types.
Do not use for
Do not use this code if the chart identifies the right or left eye, because a laterality-specific code applies. Also avoid it for retinal detachment with multiple breaks, tractional detachment, or other retinal disorders.
Coding tip
Confirm both the type of detachment and the eye laterality before assigning H33.019.
