Oth diab with moderate nonp rtnop with macular edema, unsp

This code signifies a form of diabetes mellitus, other than Type 1 or Type 2, that is complicated by moderate nonproliferative diabetic retinopathy (NPDR) with macular edema. This retinopathy stage involves microaneurysms, hemorrhages, and cotton wool spots, but no new vessel growth, and is further characterized by fluid accumulation in the macula. The specific eye affected is not documented.

Assign this code when documentation clearly indicates a diagnosis of "other specified diabetes mellitus" (e.g., secondary diabetes due to cystic fibrosis or pancreatectomy) alongside moderate NPDR with macular edema. This code requires the physician's assessment to explicitly state both the diabetes type and the specific stage of retinopathy with macular involvement.

• Always confirm the specific type of diabetes mellitus; this code is not for Type 1 or Type 2.
• Ensure documentation specifies "moderate" nonproliferative retinopathy and the presence of "macular edema."
• If the affected eye is known, a more specific code (e.g., right or left eye) should be used instead.
