Serous retinal detachment

This code represents a condition where fluid accumulates under the retina, separating it from the underlying retinal pigment epithelium. This detachment is caused by serous fluid leakage, often due to choroidal neovascularization or inflammatory processes, rather than a retinal tear. It typically leads to visual disturbances, including blurred vision or metamorphopsia.

Use this code when documentation specifies a "serous retinal detachment" or "exudative retinal detachment" without evidence of a rhegmatogenous (tear-related) cause. This diagnosis is often made following ophthalmoscopic examination, optical coherence tomography (OCT), or fluorescein angiography confirming subretinal fluid accumulation.

• Differentiate carefully from rhegmatogenous retinal detachment (e.g., 361.0x) which involves a retinal break.
• Look for documentation specifying the underlying cause of the serous detachment, if known, for potential additional coding.
• Ensure laterality (right, left, bilateral) is clearly documented, though ICD-9-CM 361.2 does not have laterality specificity.
