Oth diabetes with mild nonp rtnop without macular edema, bi

This code signifies a diagnosis of diabetes mellitus, other specified types, complicated by mild nonproliferative diabetic retinopathy affecting both eyes. Importantly, there is no evidence of macular edema in either eye. This indicates early-stage retinal microvascular damage due to diabetes.

Apply this code when documentation confirms a diagnosis of "other specified diabetes mellitus" (e.g., secondary diabetes due to pancreatectomy, drug-induced diabetes) and an ophthalmological examination reveals mild nonproliferative diabetic retinopathy in both eyes without macular edema. Supporting documentation should include an ophthalmologist's report detailing the retinopathy stage and absence of macular edema, along with the specific type of diabetes.

• Ensure the diabetes type is explicitly documented as "other specified diabetes mellitus" to differentiate from Type 1 or Type 2.
• Verify bilateral involvement and the absence of macular edema are clearly stated in the ophthalmology notes.
• This code requires a primary diabetes diagnosis; do not use it as a standalone code.
