Diabetes with mild nonp rtnop with macular edema, left eye

This code signifies diabetes that is a consequence of another underlying medical condition, specifically presenting with early-stage diabetic retinopathy in the left eye. The retinopathy is characterized by mild nonproliferative changes and is complicated by swelling of the macula, the central part of the retina responsible for sharp vision.

Use this code when documentation clearly states diabetes due to an underlying condition (e.g., cystic fibrosis-related diabetes, pancreatectomy-induced diabetes) and identifies mild nonproliferative diabetic retinopathy with macular edema affecting the left eye. This code requires explicit linkage between the underlying condition and the diabetes, as well as specific laterality and severity of the retinopathy.

• Always sequence the underlying condition first, followed by this diabetes code.
• Ensure documentation specifies "mild nonproliferative" and "macular edema" in the "left eye" for accurate coding.
• Distinguish from type 1 or type 2 diabetes with retinopathy; this code is specifically for diabetes due to an underlying condition.
