Type 1 diabetes mellitus with periodontal disease

This code identifies a patient diagnosed with Type 1 diabetes mellitus who also presents with periodontal disease. It signifies the co-occurrence of these two distinct conditions, highlighting the systemic impact of diabetes on oral health.

Apply this code when documentation clearly states a diagnosis of Type 1 diabetes and a concurrent diagnosis of periodontal disease. This is appropriate for patients receiving treatment for either or both conditions, where the physician explicitly links or notes the presence of both.

• Ensure documentation specifies "Type 1" diabetes; do not use for Type 2 or unspecified diabetes.
• Verify that periodontal disease is explicitly documented, not just gingivitis or other non-periodontal oral conditions.
• Sequence this code as a secondary diagnosis if the primary reason for the encounter is related to the periodontal disease, or as a primary diagnosis if the encounter is for diabetes management and periodontal disease is a significant co-morbidity.
