Retinal neovascularization, unspecified, left eye

This code signifies the abnormal growth of new blood vessels on the retina of the left eye, where the specific type or cause of the neovascularization is not documented. This condition can lead to vision impairment or loss due to hemorrhage, fibrosis, or retinal detachment. It represents an unspecified form of retinal neovascularization affecting only the left eye.

Use this code when documentation clearly indicates retinal neovascularization in the left eye, but the physician has not specified the type (e.g., proliferative diabetic retinopathy, wet age-related macular degeneration, or other specific causes). This code is appropriate when the laterality is confirmed as left, and the provider has not yet determined or documented the underlying etiology.

• Ensure documentation specifies "unspecified" or lacks further detail regarding the type of retinal neovascularization.
• Always confirm laterality; do not use this code if the right eye or bilateral involvement is documented.
• Prioritize more specific codes if the underlying cause (e.g., diabetes, AMD) or type of neovascularization is known and documented.
