Type 2 diabetes mellitus with diabetic dermatitis

This code identifies type 2 diabetes mellitus complicated by diabetic dermatitis. Diabetic dermatitis refers to various skin conditions directly attributable to the metabolic effects of diabetes, such as diabetic dermopathy, bullosis diabeticorum, or necrobiosis lipoidica diabeticorum. It signifies a direct causal link between the patient's diabetes and their skin manifestation.

Use this code when documentation clearly links a patient's type 2 diabetes to a diagnosis of dermatitis. This typically occurs when a physician explicitly states "diabetic dermatitis" or a specific dermatological condition known to be a complication of diabetes, in a patient with type 2 diabetes. The medical record should support the diabetic etiology of the skin condition.

• Ensure the documentation explicitly states the dermatitis is a diabetic complication, not merely co-occurring.
• Do not use this code for general skin infections or non-diabetic dermatological conditions in a diabetic patient.
• Sequence this code as the primary diagnosis if the dermatitis is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity being managed.
