Other specified diabetes mellitus with foot ulcer

This code signifies a form of diabetes mellitus, other than Type 1 or Type 2, that is complicated by the presence of a foot ulcer. This could include diabetes secondary to other conditions or drug-induced diabetes. The foot ulcer is a direct consequence of the diabetic condition.

Apply this code when documentation specifies "other specified diabetes mellitus" and clearly indicates a foot ulcer as a complication. This code is appropriate when the provider explicitly diagnoses a type of diabetes not classified as Type 1 or Type 2, such as secondary diabetes due to pancreatitis, and notes a diabetic foot ulcer.

• Always code the underlying diabetes first, followed by the foot ulcer.
• Ensure the medical record specifies "other specified diabetes mellitus" and not Type 1 or Type 2.
• Do not use this code if the foot ulcer is not explicitly documented as diabetic in origin.
