Type 2 diabetes mellitus with periodontal disease

This code signifies a diagnosis of type 2 diabetes mellitus complicated by the presence of periodontal disease. It indicates a direct clinical association between the patient's diabetes and their gum disease, reflecting the known bidirectional relationship between these conditions.

Use this code when documentation explicitly states a diagnosis of type 2 diabetes and also identifies periodontal disease in the same patient. This is appropriate when the clinician has established a link or comorbidity between the two conditions, often seen in patients with poorly controlled diabetes.

• Ensure the documentation specifies "type 2" diabetes; do not use for type 1 or unspecified diabetes.
• Verify that "periodontal disease" is clearly documented, not just gingivitis or other non-periodontal gum conditions.
• This code inherently links the two conditions; no additional code for the diabetes type is needed, but an additional code for the specific type of periodontal disease (e.g., K05.20) may be appropriate for further specificity.
