ICD-10 Code H33.0 – Retinal detachment with retinal break (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.0 – Retinal detachment with retinal break
What it is
H33.0 identifies a retinal detachment caused by a retinal break, such as a tear or hole. Use it when documentation shows the retina has separated because fluid passed through the break.
Clinical signs
Typical findings include sudden flashes, new floaters, and a curtain-like shadow or peripheral vision loss. Clinical features vary; refer to documentation.
When to use this code
Use H33.0 when the provider documents retinal detachment with a confirmed retinal break. It fits ophthalmology notes describing detachment due to a tear, hole, or similar break. If the record does not clearly link the detachment to a break, check documentation.
Do not use for
Do not use this code for retinal detachment without a documented break, or for other retinal disorders such as tears without detachment. Check documentation.
Coding tip
Look for explicit wording that ties the detachment to the retinal break before assigning H33.0.
