ICD-10 Code H33.2 – Serous Retinal Detachment (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.2 – Serous retinal detachment
What it is
H33.2 identifies serous retinal detachment, where fluid collects under the retina and separates it from the underlying tissue. It is not caused by a retinal tear; check documentation for the underlying cause.
Clinical signs
Common findings include blurred or distorted vision, a visual field defect, and retinal elevation with subretinal fluid on examination. Clinical features vary; refer to documentation.
When to use this code
Use H33.2 when the provider documents serous, exudative, or nonrhegmatogenous retinal detachment. It fits cases where imaging or ophthalmic exam confirms subretinal fluid without a tear. Code the documented eye and underlying condition when specified.
Do not use for
Do not use this code for rhegmatogenous retinal detachment, tractional detachment, or unspecified retinal detachment. If the record does not clearly state serous detachment, check documentation.
Coding tip
Confirm the detachment type and laterality in the ophthalmology note before assigning H33.2.
