ICD-10 Code H33.012 – Retinal detachment with single break, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.012 – Retinal detachment with single break, left eye
What it is
This code identifies a retinal detachment in the left eye caused by one retinal break. The retina separates from the underlying tissue, which can threaten vision and usually requires prompt ophthalmic evaluation.
Clinical signs
Typical findings include flashes, new floaters, a curtain-like shadow, or decreased vision in the affected eye. Clinical features vary; refer to documentation, and confirm the left eye and single-break detail.
When to use this code
Use H33.012 when the provider documents retinal detachment of the left eye with one retinal tear or hole as the cause. It is appropriate for confirmed diagnoses in outpatient, inpatient, or operative records. You should code the laterality and the single-break detail exactly as documented.
Do not use for
Do not use this code for retinal detachment in the right eye, bilateral disease, or detachments without a documented single break. Check documentation if the record does not specify laterality or the type of retinal break.
Coding tip
Verify the eye and the number of breaks in the ophthalmology note before assigning H33.012.
