This code signifies diabetes mellitus resulting from drug or chemical exposure, specifically presenting with advanced diabetic eye disease affecting both eyes. The retinopathy has progressed to the proliferative stage, characterized by new blood vessel growth, and has led to tractional detachment of the retina, with the macula (central vision area) being involved.

Apply this code when documentation clearly indicates drug or chemical-induced diabetes and bilateral proliferative diabetic retinopathy with macula-involving traction retinal detachment. This typically occurs in patients with a history of medication-induced hyperglycemia who develop severe, vision-threatening diabetic eye complications. Supporting documentation would include ophthalmology reports detailing the specific type and extent of retinopathy and retinal detachment.

• Always sequence the underlying drug or chemical poisoning code (T36-T65) as the primary diagnosis, followed by this code.
• Ensure documentation specifies "bilateral" involvement and "macula involving" for accurate coding.
• Distinguish from non-proliferative retinopathy or detachments not involving the macula, which would require different codes.
