Oth diabetes mellitus with diabetic polyneuropathy

This code signifies a form of diabetes mellitus, not classified as Type 1 or Type 2, that has resulted in damage to multiple peripheral nerves. This polyneuropathy is a direct complication of the patient's underlying diabetes.

Apply this code when documentation specifies "other specified diabetes mellitus" and explicitly states the presence of diabetic polyneuropathy. This is appropriate for patients whose diabetes type is documented as something other than Type 1 or Type 2 (e.g., secondary diabetes due to pancreatectomy) and who are experiencing nerve damage attributable to their diabetic condition.

• Always code the underlying diabetes first, followed by the manifestation.
• Ensure the documentation clearly links the polyneuropathy to the diabetes.
• Distinguish from mononeuropathy or other neurological conditions not directly caused by diabetes.
