Traction detachment of retina, left eye

This code signifies a retinal detachment in the left eye caused by vitreoretinal traction, where fibrous bands or membranes pull on the retina, separating it from the underlying retinal pigment epithelium. This type of detachment is often associated with proliferative diabetic retinopathy or other conditions causing vitreous hemorrhage or inflammation.

Apply this code when documentation explicitly states a tractional retinal detachment affecting the left eye. This diagnosis is typically confirmed via ophthalmoscopy, B-scan ultrasonography, or optical coherence tomography (OCT) showing vitreoretinal traction. The physician's notes should clearly indicate the etiology as tractional.

• Ensure the documentation specifies "tractional" as the cause of detachment, differentiating it from rhegmatogenous or exudative types.
• Verify laterality; this code is specific to the left eye. Use the appropriate code for the right eye or bilateral involvement.
• Code any underlying conditions, such as diabetic retinopathy, that led to the tractional detachment, following sequencing guidelines.
