Oth diabetes with moderate nonp rtnop with macular edema, bi

This code signifies a patient diagnosed with a form of diabetes mellitus other than type 1 or type 2, who also presents with a specific stage of diabetic retinopathy. The retinopathy is characterized as moderate nonproliferative, meaning there are signs of damage to the retinal blood vessels but without new, abnormal vessel growth. Crucially, both eyes are affected, and there is swelling in the macula, the central part of the retina responsible for sharp, detailed vision.

Use this code when documentation clearly indicates "other specified diabetes mellitus" as the underlying diabetic condition. The ophthalmologist's or endocrinologist's notes must explicitly state "moderate nonproliferative diabetic retinopathy" with "macular edema" affecting "both eyes." This code is appropriate for patients undergoing treatment or monitoring for this specific combination of diabetic complications.

• Ensure the type of diabetes is documented as "other specified" (e.g., secondary diabetes, genetic defects in beta-cell function) and not type 1 or type 2.
• Verify that both the severity of retinopathy (moderate nonproliferative) and the presence of macular edema are clearly documented for both eyes.
• Always sequence the diabetes code (E13.-) first, followed by any associated complications, unless a specific guideline dictates otherwise.
