Oth diab with prolif diab rtnop with comb detach, left eye

This code signifies a complex manifestation of other specified diabetes mellitus, characterized by the presence of proliferative diabetic retinopathy in the left eye. This retinopathy has progressed to include both tractional and rhegmatogenous retinal detachments, indicating severe ocular complications from the diabetes.

Apply this code when documentation clearly states a diagnosis of "other specified diabetes mellitus" and specifies proliferative diabetic retinopathy in the left eye, along with the co-occurrence of both tractional and rhegmatogenous retinal detachments. This code is appropriate for patients with advanced diabetic eye disease requiring significant medical and surgical intervention.

• Ensure the documentation explicitly states "other specified diabetes mellitus" and not type 1 or type 2.
• Verify that both tractional and rhegmatogenous retinal detachments are present and affect the left eye.
• Confirm the presence of proliferative diabetic retinopathy; this code is not for nonproliferative stages.
