Oth diabetes mellitus with diabetic mononeuropathy

This code describes a form of diabetes mellitus, other than type 1 or type 2, that is complicated by diabetic mononeuropathy. Diabetic mononeuropathy is a condition where a single nerve or nerve group is damaged due to the effects of diabetes, often presenting with sudden onset pain, weakness, or numbness in the affected area.

Use this code when documentation specifies "other specified diabetes mellitus" (e.g., secondary diabetes due to pancreatectomy, drug-induced diabetes) and explicitly states the presence of diabetic mononeuropathy. This code is appropriate when the physician's diagnosis clearly links the mononeuropathy to the patient's diabetes.

• Always sequence the diabetes code first, followed by codes for any associated complications.
• Ensure the documentation specifies "mononeuropathy" and not a more generalized polyneuropathy, which would require a different code.
• Verify the type of diabetes is clearly documented as "other specified" to differentiate from type 1 (E10.-) or type 2 (E11.-) diabetes.
