What This Code Means

Type 2 diabetes causing various mouth and oral problems beyond periodontal disease, such as oral infections or dry mouth.

Coding Tips

• •Document the specific oral complication to justify use of this code over more specific alternatives
• •Ensure the oral condition is directly attributable to diabetes rather than another cause

Clinical Significance

Type 2 diabetes mellitus with other oral complications captures diabetes-related mouth conditions beyond periodontal disease, including oral candidiasis, xerostomia, angular cheilitis, burning mouth syndrome, and impaired taste sensation. These conditions result from microvascular damage, immune dysfunction, salivary gland changes, and altered oral flora associated with chronic hyperglycemia. They can significantly impact nutrition, medication adherence, and quality of life.

Documentation Requirements

• ✓The provider must identify the specific oral complication and establish its relationship to Type 2 diabetes.
• ✓Documentation should describe the oral condition, functional impact, and treatment provided.
• ✓The record must confirm the condition is not periodontal disease (E11.630), which has its own specific code.
• ✓Dental or oral medicine specialist findings strengthen the documentation.
