ICD-10 Code H33.04 – Retinal detachment with retinal dialysis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.04 – Retinal detachment with retinal dialysis
What it is
H33.04 identifies a retinal detachment caused by retinal dialysis, a tear or separation at the retinal periphery. Use it when the chart clearly documents this specific type of detachment.
Clinical signs
Patients may report flashes, floaters, or a shadow/curtain over vision. Clinical features vary; refer to documentation and ophthalmology findings confirming retinal detachment with dialysis.
When to use this code
Use this code when the provider documents retinal detachment with retinal dialysis, including operative, consult, or exam notes. It is appropriate when dialysis is the stated cause or associated finding, not just a general retinal tear. Check documentation if the record only says retinal detachment without specifying dialysis.
Do not use for
Do not use it for retinal tears, retinal dialysis without detachment, or unspecified retinal detachment. If the note lacks the dialysis detail, choose the documented diagnosis instead.
Coding tip
Assign H33.04 only when both detachment and dialysis are documented together.
