Oth diab with prolif diab rtnop with macular edema, left eye

This code signifies a form of diabetes mellitus, not otherwise specified as Type 1 or Type 2, that has led to proliferative diabetic retinopathy (PDR) in the left eye. PDR is an advanced stage of diabetic eye disease characterized by the growth of abnormal new blood vessels on the retina, which in this specific case, is complicated by macular edema, swelling of the central part of the retina.

Apply this code when documentation clearly indicates a diagnosis of "other specified diabetes mellitus" alongside proliferative diabetic retinopathy affecting the left eye, with explicit mention of co-occurring macular edema. This code is appropriate for patients with established diabetes where the specific type is documented as "other specified" (e.g., secondary diabetes due to pancreatectomy) and ophthalmological examination confirms both PDR and macular edema in the left eye.

• Ensure the documentation specifies "other specified diabetes mellitus" and not Type 1 or Type 2.
• Verify laterality for both PDR and macular edema is explicitly stated as "left eye."
• Always sequence the diabetes code first, followed by codes for any associated complications.
