ICD-10 Code H33.23 – Serous retinal detachment, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.23 – Serous retinal detachment, bilateral
What it is
H33.23 identifies serous retinal detachment in both eyes, meaning fluid has collected under the retina without a tear or hole. It is a bilateral retinal separation that can impair vision.
Clinical signs
Clinical features vary; refer to documentation. Common findings include blurred vision, visual distortion, or a shadowed area, with retinal elevation and subretinal fluid noted on examination or imaging.
When to use this code
Use H33.23 when the provider documents serous retinal detachment affecting both eyes. This is appropriate when the record clearly states bilateral involvement and does not describe a rhegmatogenous or tractional detachment.
Code it from ophthalmology documentation, imaging, or exam findings that support bilateral serous detachment. If the record is unclear about laterality or detachment type, check documentation before assigning the code.
Do not use for
Do not use this code for retinal detachment with a tear, tractional detachment, or a unilateral serous detachment. Check documentation if the diagnosis is only suspected.
Coding tip
Confirm both laterality and detachment type in the note, because these details determine whether H33.23 is correct.
