Oth diab with prolif diab rtnop without macular edema, bi

This code signifies a diagnosis of diabetes mellitus, other specified type, complicated by proliferative diabetic retinopathy affecting both eyes. Importantly, there is no associated macular edema in either eye. This represents an advanced stage of diabetic eye disease characterized by abnormal new blood vessel growth on the retina.

Use this code when documentation explicitly states "other specified diabetes mellitus" and "proliferative diabetic retinopathy" bilaterally, with a clear absence of macular edema. This is typically found in ophthalmology reports or endocrinology notes detailing diabetic complications. Supporting documentation would include funduscopic examination findings, OCT scans confirming no macular edema, and a confirmed diagnosis of the specific diabetes type.

• Always verify the specific type of diabetes mellitus; "other specified" is distinct from Type 1 or Type 2.
• Ensure documentation clearly states "proliferative" retinopathy and "without macular edema" for both eyes.
• Sequence this code after the primary diabetes mellitus code (e.g., E13.xx) to indicate the manifestation.
