Drug/chem diab w prolif diab rtnop with comb detach, r eye

This code describes a form of diabetes mellitus caused by drugs or chemicals, specifically presenting with advanced diabetic eye disease in the right eye. The retinopathy has progressed to a proliferative stage, characterized by the growth of abnormal new blood vessels, and has led to a complex retinal detachment involving both tractional forces and a retinal break.

Use this code when documentation clearly indicates drug or chemical-induced diabetes mellitus as the etiology, and the patient presents with proliferative diabetic retinopathy in the right eye complicated by a combined tractional and rhegmatogenous retinal detachment. This diagnosis requires specific documentation of the drug/chemical causation of the diabetes and the precise nature and laterality of the retinal detachment.

• Ensure documentation explicitly states "drug or chemical induced" diabetes, not simply type 1 or type 2.
• Verify that both "proliferative diabetic retinopathy" and "combined traction retinal detachment and rhegmatogenous retinal detachment" are present in the right eye.
• Always sequence the underlying drug/chemical-induced diabetes code first, followed by codes for associated complications.
