ICD-10 Code H33.021 – Retinal detachment with multiple breaks, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.021 – Retinal detachment with multiple breaks, right eye
What it is
This code identifies a retinal detachment in the right eye caused by more than one retinal break. Use it when the documentation specifies both the eye and the presence of multiple breaks.
Clinical signs
Typical findings include sudden flashes, new floaters, or a curtain-like shadow in vision. Clinical features vary; refer to documentation and ophthalmology findings for confirmation.
When to use this code
Use H33.021 when the provider documents retinal detachment of the right eye with multiple breaks, even if the note does not describe every break in detail. It is appropriate for confirmed diagnoses from examination, imaging, or specialist assessment. Check documentation if the laterality or number of breaks is unclear.
Do not use for
Do not use this code for retinal detachment without multiple breaks, or when the affected eye is not the right eye. If the record only says retinal tear, check documentation.
Coding tip
Verify laterality and the phrase “multiple breaks” in the provider note before assigning this code.
