Type 1 diab with prolif diab rtnop without mclr edema, unsp

This code signifies a patient diagnosed with Type 1 diabetes who has developed proliferative diabetic retinopathy, a severe form of diabetic eye disease characterized by new, abnormal blood vessel growth on the retina. Importantly, there is no associated macular edema, and the specific eye affected is not documented.

Use this code when documentation clearly states Type 1 diabetes and proliferative diabetic retinopathy without macular edema, but the laterality (left, right, or bilateral) is not specified. This code is appropriate when the physician explicitly diagnoses these conditions and there is no mention of macular swelling.

• Always strive for greater specificity regarding laterality (e.g., E10.3591 for right eye, E10.3592 for left eye, E10.3593 for bilateral).
• Do not use this code if macular edema is present; instead, select a code from the E10.351- subcategory.
• Ensure the documentation confirms Type 1 diabetes, not Type 2, as this impacts the primary diabetes code.
