Total retinal detachment, left eye

This code signifies a complete separation of the neurosensory retina from the underlying retinal pigment epithelium in the left eye. This detachment involves the entire retinal surface, leading to significant vision loss in the affected eye. It is a severe ophthalmic emergency requiring prompt surgical intervention.

This code is appropriate when documentation clearly indicates a total retinal detachment affecting the left eye. Supporting clinical notes should describe the extent of the detachment as complete, often including findings such as a "bullous" or "total" detachment on ophthalmoscopy or imaging. It is used for the initial diagnosis and subsequent encounters related to this specific condition.

• Ensure laterality is accurately documented and coded; this code is specific to the left eye.
• Distinguish from partial retinal detachments (H33.01-) or detachments with retinal breaks (H33.02-).
• Always check for associated conditions, such as retinal breaks or proliferative vitreoretinopathy, and code them additionally if present.
