Type 1 diabetes mellitus with foot ulcer

This code signifies a patient diagnosed with Type 1 diabetes who has developed an ulcer on their foot. It indicates a specific diabetic complication affecting the lower extremities, often due to neuropathy, peripheral vascular disease, or a combination of factors.

Apply this code when documentation clearly states Type 1 diabetes and a foot ulcer. This is appropriate for initial encounters, subsequent care, or when monitoring the progression of the foot ulcer in a Type 1 diabetic patient. Ensure the physician's notes specify the type of diabetes.

• Always code the specific type of diabetes (Type 1 or Type 2) when a foot ulcer is present.
• Do not use this code if the foot ulcer is not explicitly linked to the patient's diabetes.
• Sequence this code before codes for specific ulcer characteristics (e.g., stage, laterality) or associated infections.
