Drug/chem diab w prolif diab rtnop w trctn dtch n-mcla,l eye

This code signifies diabetes mellitus caused by a drug or chemical, specifically complicated by proliferative diabetic retinopathy. The retinopathy has progressed to include tractional retinal detachment in the left eye, but this detachment does not involve the macula, preserving central vision.

Use this code when documentation clearly states drug or chemical-induced diabetes with proliferative retinopathy and a non-macular traction retinal detachment in the left eye. This is typically found in ophthalmology reports or endocrinology notes detailing diabetic complications.

• Always sequence the underlying drug or chemical as an external cause code (T36-T65) after this diabetes code.
• Ensure documentation specifies "proliferative" retinopathy and "traction" retinal detachment, as well as laterality and macular involvement.
• Distinguish from diabetic retinopathy without tractional detachment or with serous/rhegmatogenous detachment.
