What This Code Means

This code describes a type of diabetes (not type 1 or type 2) that is causing skin problems beyond the common diabetic complications. These skin issues could include infections, ulcers, or other conditions directly related to the diabetes.

Coding Tips

• •Ensure the documentation specifies 'other specified diabetes mellitus' rather than type 1 or type 2 diabetes, and clearly identifies the specific skin complication present
• •The fifth character '2' indicates 'with complications' and the sixth character '8' specifies 'other skin complications' - verify the skin condition is documented and related to the diabetes before assigning this code

Clinical Significance

E13.628 captures other skin complications of other specified diabetes mellitus beyond dermatitis and ulcers. These include conditions such as diabetic thick skin (scleredema diabeticorum), acanthosis nigricans associated with insulin resistance, granuloma annulare, or other dermatologic manifestations directly attributable to the metabolic dysfunction of secondary diabetes.

Documentation Requirements

• ✓The provider must document the secondary diabetes, the specific skin complication, and its causal relationship to diabetes.
• ✓The condition must not fit into the dermatitis (E13.620) or ulcer (E13.621/E13.622) subcategories.
• ✓Dermatologic examination and clinical description should support the diagnosis.
