What This Code Means

A type of diabetes (not type 1 or type 2) that causes skin inflammation or dermatitis as a complication.

Coding Tips

• •Ensure documentation specifies this is diabetic dermatitis, not a separate skin condition

Diabetic dermopathy, necrobiosis lipoidica diabeticorum, and diabetic bullae are examples of diabetes-specific skin conditions that reflect underlying microvascular damage and impaired skin integrity.

Documentation Requirements

• ✓The provider must document secondary diabetes and the specific skin condition with a causal link to diabetes.
