Diab with prolif diab rtnop without macular edema, left eye

This code signifies diabetes mellitus that has developed as a consequence of another underlying medical condition, specifically presenting with proliferative diabetic retinopathy in the left eye. Proliferative diabetic retinopathy is an advanced stage of diabetic eye disease characterized by the growth of new, abnormal blood vessels on the retina, but without swelling of the macula.

Use this code when a patient has secondary diabetes (e.g., due to pancreatitis, cystic fibrosis, or drug-induced) and is diagnosed with proliferative diabetic retinopathy affecting only the left eye, with no mention of macular edema. Documentation should clearly state the underlying condition causing the diabetes, the specific eye affected, and the absence of macular edema.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Distinguish carefully between proliferative and nonproliferative diabetic retinopathy; this code is specific to the proliferative stage.
• Verify laterality (left eye) and confirm the absence of macular edema to ensure accurate code selection.
