ICD-10 Code H33.002 – Unspecified retinal detachment with retinal break, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.002 – Unspecified retinal detachment with retinal break, left eye
What it is
This code identifies a retinal detachment in the left eye caused by a retinal break, when the type of detachment is not further specified. Use it when documentation confirms both the left eye and a break in the retina.
Clinical signs
Typical findings may include sudden flashes, floaters, a curtain-like shadow, or decreased vision. Clinical features vary; refer to documentation and ophthalmology findings confirming retinal detachment with a retinal break.
When to use this code
Use H33.002 when the provider documents an unspecified retinal detachment with a retinal break affecting the left eye. It also fits when the record does not identify the detachment subtype, but does confirm the break and laterality. Do not code from symptoms alone.
Do not use for
Do not use this code if the detachment is in the right eye, both eyes, or if no retinal break is documented. Check documentation if the record instead describes retinal tear without detachment.
Coding tip
Always verify laterality and the presence of a retinal break before assigning H33.002.
