Other specified diabetes mellitus with diabetic dermatitis

This code signifies a form of diabetes mellitus, not classified as Type 1 or Type 2, that is complicated by diabetic dermatitis. Diabetic dermatitis refers to various skin conditions directly attributable to diabetes, such as diabetic dermopathy, bullosis diabeticorum, or necrobiosis lipoidica diabeticorum. It indicates a systemic impact of the diabetes on the integumentary system.

Apply this code when documentation specifies "other specified diabetes mellitus" and explicitly links a dermatological condition to the patient's diabetes. This typically requires a physician's diagnosis of both the specific type of diabetes and the associated skin manifestation. Look for terms like "diabetic skin changes" or specific dermatoses attributed to diabetes in patients with non-Type 1/Type 2 diabetes.

• Always sequence the diabetes code first, followed by a more specific code for the type of dermatitis if available and not already inherent in the diabetes complication.
• Ensure the medical record clearly establishes a causal link between the "other specified diabetes" and the skin condition.
• Distinguish from skin conditions that are merely co-occurring with diabetes but not directly caused by it.
