Diab with moderate nonp rtnop without macular edema, unsp

This code signifies diabetes mellitus that has developed as a consequence of another underlying medical condition, rather than being Type 1 or Type 2. The patient exhibits moderate nonproliferative diabetic retinopathy, a stage of retinal damage characterized by microaneurysms and hemorrhages, but without any swelling in the macula, affecting an unspecified eye.

Use this code when documentation clearly states diabetes is secondary to another condition (e.g., pancreatitis, cystic fibrosis, drug-induced) and the patient has moderate nonproliferative diabetic retinopathy without macular edema. The eye affected is not specified in the clinical notes. Ensure the underlying condition causing the diabetes is also coded.

• Always code the underlying condition causing the diabetes first, followed by this code.
• Distinguish carefully between "unspecified eye" and situations where the laterality (left, right, bilateral) is known but not explicitly stated in the code description.
• Do not use if macular edema is present; a different subcategory of E08.3 will be required.
