Retinal detachment with giant retinal tear, left eye

This code signifies a serious ocular condition where the retina detaches from the underlying choroid due to a large, horseshoe-shaped or circumferential tear involving 90 degrees (3 clock hours) or more of the retinal circumference in the left eye. This type of detachment often leads to significant vision loss if not promptly treated.

Apply this code when documentation explicitly states a diagnosis of retinal detachment with a giant retinal tear affecting the left eye. This typically occurs following trauma, high myopia, or previous intraocular surgery. Supporting documentation should include ophthalmological examination findings detailing the size and location of the retinal tear.

• Differentiate from other types of retinal detachment (e.g., rhegmatogenous, exudative, tractional) which have distinct codes.
• Ensure laterality is clearly documented and correctly assigned (left eye in this case).
• Verify the tear meets the "giant" criteria (90 degrees or more) to avoid miscoding as a standard retinal tear with detachment.
