Drug/chem diab with prolif diab rtnop with mclr edema, unsp

This code describes a form of diabetes mellitus caused by a drug or chemical, specifically complicated by proliferative diabetic retinopathy affecting the macula with associated edema. This advanced stage of retinopathy involves new, fragile blood vessel growth and swelling in the central part of the retina, leading to significant vision impairment. The laterality of the affected eye is not specified.

Use this code when documentation clearly indicates drug- or chemical-induced diabetes and the patient has been diagnosed with proliferative diabetic retinopathy with macular edema. This diagnosis typically follows an ophthalmological examination, including imaging such as OCT, confirming macular edema and neovascularization. Ensure the medical record specifies the diabetes etiology as drug or chemical induced.

• Always sequence the drug or chemical responsible for the diabetes as an additional code, if known.
• Distinguish carefully between nonproliferative and proliferative retinopathy; this code is specific to the proliferative form.
• Verify the presence of macular edema, as separate codes exist for proliferative retinopathy without macular edema.
