ICD-10 Code E13.630 – Other specified diabetes mellitus with periodontal disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.630 – Other specified diabetes mellitus with periodontal disease
What it is
This code identifies periodontal disease occurring with other specified diabetes mellitus. Use it when the record links the diabetes type to gum disease, but the diabetes does not fit another specific category.
Clinical signs
Common findings include gingival inflammation, bleeding, periodontal pocketing, and bone loss around teeth. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents periodontal disease in a patient with other specified diabetes mellitus and clearly connects the two conditions. It is appropriate for encounters focused on diabetic periodontal complications or related oral evaluations. Check documentation if the diabetes type is not clearly specified.
Do not use for
Do not use it for diabetes without periodontal disease, or for periodontal disease unrelated to diabetes. Do not assign it when the diabetes is better classified under another ICD-10-CM diabetes category.
Coding tip
Verify both the diabetes type and the periodontal diagnosis are documented together before assigning E13.630.
