Oth diab with prolif diab rtnop without macular edema, r eye

This code signifies a form of diabetes mellitus, not otherwise classified as type 1 or type 2, that has led to the development of proliferative diabetic retinopathy in the patient's right eye. Proliferative retinopathy is an advanced stage of diabetic eye disease characterized by the growth of abnormal new blood vessels on the retina. Importantly, there is no associated macular edema in this specific instance.

Use this code when documentation clearly indicates a diagnosis of "other specified diabetes mellitus" and the patient presents with proliferative diabetic retinopathy affecting the right eye, with explicit notation that macular edema is absent. This code is appropriate when the physician's assessment confirms the presence of new vessel formation on the optic disc or elsewhere on the retina.

• Ensure the medical record specifies "other specified diabetes mellitus" and not type 1 or type 2.
• Verify laterality (right eye) and the absence of macular edema are explicitly documented.
• Always code the underlying diabetes first, followed by this code for the manifestation.
