What This Code Means

Type 2 diabetes causing various skin problems not specifically classified elsewhere, such as necrobiosis or diabetic bullae.

Coding Tips

• •Use this code only when the specific skin complication doesn't fit other more specific diabetic skin codes
• •Document the exact nature of the skin complication for clarity and medical necessity

Clinical Significance

Type 2 diabetes mellitus with other skin complications captures a range of diabetes-related skin conditions beyond dermatitis and ulceration, including necrobiosis lipoidica, diabetic bullae (blisters), scleroderma diabeticorum, eruptive xanthomas, acanthosis nigricans, and diabetic thick skin. These conditions serve as clinical markers of metabolic derangement and may indicate the need for more aggressive glycemic management.

Documentation Requirements

• ✓The provider must document the specific skin complication and establish its causal relationship to Type 2 diabetes.
• ✓Description of the appearance, location, extent, and any treatment should be recorded.
• ✓The documentation must confirm the condition is not dermatitis (E11.620) or ulceration (E11.621/E11.622), which have their own specific codes.
• ✓Dermatological consultation findings strengthen documentation.
