ICD-10 Code H33.059 – Total Retinal Detachment, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.059 – Total retinal detachment, unspecified eye
What it is
This code identifies a complete retinal detachment in an eye when the affected side is not specified. The retina has separated from the underlying tissue, which can threaten vision and needs prompt evaluation.
Clinical signs
Typical findings include sudden flashes, new floaters, a curtain-like shadow, or reduced vision. Clinical features vary; refer to documentation and the ophthalmology exam for confirmation.
When to use this code
Use H33.059 when the record states total retinal detachment but does not identify right or left eye. It also fits when the provider documents retinal detachment without laterality and the condition is clearly total. Check documentation if the note describes a partial, tractional, or rhegmatogenous detachment instead.
Do not use for
Do not use this code for partial retinal detachment, retinal tears without detachment, or detachment with documented laterality. If the chart specifies the eye or a different detachment type, choose the more specific code.
Coding tip
Assign the unspecified-eye code only after confirming the record truly lacks laterality.
