ICD-10 Code H33.01 – Retinal detachment with single break (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.01 – Retinal detachment with single break
What it is
H33.01 identifies a retinal detachment caused by one retinal break. Use it when the chart documents a detached retina with a single tear or hole as the source.
Clinical signs
Typical findings include sudden flashes, new floaters, and a curtain-like visual field defect. Clinical features vary; refer to documentation, especially the eye exam or ophthalmology report.
When to use this code
Use this code when the provider documents retinal detachment and specifically states a single break. It fits operative notes, consultation reports, or problem lists that clearly identify one retinal tear or hole.
If the record does not specify the number of breaks, check documentation before coding. Do not infer a single break from general retinal detachment language alone.
Do not use for
Do not use H33.01 for retinal detachment with multiple breaks, tractional detachment, or detachment due to another stated cause. Check documentation if the type of detachment is unclear.
Coding tip
Confirm both detachment and the single break in the same source note before assigning H33.01.
