Type 1 diabetes mellitus with diabetic dermatitis

This code signifies a patient diagnosed with Type 1 diabetes mellitus who also presents with diabetic dermatitis. Diabetic dermatitis refers to skin conditions directly caused or exacerbated by diabetes, such as shin spots, diabetic bullae, or necrobiosis lipoidica diabeticorum. It indicates a specific dermatological complication arising from the underlying autoimmune metabolic disorder.

Apply this code when documentation clearly states a diagnosis of Type 1 diabetes and a co-occurring skin condition explicitly identified as diabetic dermatitis. This typically occurs in patients with long-standing or poorly controlled Type 1 diabetes. Supporting documentation should include physician notes detailing both the diabetes type and the specific dermatological manifestation.

• Ensure the documentation specifies "Type 1" diabetes; do not use for other types of diabetes.
• Verify the skin condition is explicitly linked to diabetes (e.g., "diabetic shin spots," "diabetic dermopathy") rather than a general dermatological issue.
• Sequence this code after the primary diabetes code if another complication is more severe, or as the principal diagnosis if the dermatitis is the primary reason for the encounter.
