Serous retinal detachment, left eye

This code signifies the separation of the neurosensory retina from the underlying retinal pigment epithelium due to the accumulation of serous fluid in the subretinal space, specifically affecting the left eye. This detachment is typically non-rhegmatogenous, meaning it's not caused by a retinal tear or break.

Apply this code when documentation clearly indicates a serous detachment of the retina in the patient's left eye. This is often seen in conditions like central serous chorioretinopathy, inflammatory processes, or choroidal tumors. Supporting documentation should include ophthalmological exam findings, imaging (e.g., OCT, fluorescein angiography), and a definitive diagnosis of serous detachment.

• Ensure laterality is precisely documented and coded; do not use unspecified eye codes if the left eye is clearly affected.
• Distinguish carefully from rhegmatogenous retinal detachment (H33.0-) which involves a retinal break.
• Code any underlying systemic or ocular conditions contributing to the serous detachment, such as central serous chorioretinopathy (H35.7-), as primary or secondary diagnoses as appropriate.
