ICD-10 Code H33.049 – Retinal detachment with retinal dialysis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.049 – Retinal detachment with retinal dialysis, unspecified eye
What it is
This code identifies a retinal detachment caused by retinal dialysis, with no eye specified. Retinal dialysis is a separation of the retina at its outer edge, which can allow fluid to lift the retina.
Clinical signs
Clinical features vary; refer to documentation. Common findings include symptoms of retinal detachment such as flashes, floaters, or a shadow over vision, along with exam evidence of retinal separation related to dialysis.
When to use this code
Use H33.049 when the record documents retinal detachment due to retinal dialysis and laterality is not stated. You should code it when the diagnosis is confirmed by ophthalmic examination or specialist documentation. If the provider specifies right or left eye, use the more specific code instead.
Do not use for
Do not use this code for retinal detachment without dialysis, or for dialysis without detachment. Also avoid it when the affected eye is documented, because unspecified eye is less precise.
Coding tip
Check the ophthalmology note for laterality and the exact relationship between dialysis and detachment before selecting this unspecified-eye code.
