ICD-10 Code E13.63 – Other specified diabetes mellitus with oral complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.63 – Other specified diabetes mellitus with oral complications
What it is
This code identifies diabetes mellitus from other specified causes when it is documented with oral complications. It tells you the diabetes type is not one of the standard categories, and the mouth involvement is part of the diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Oral findings may include gum disease, mouth infections, delayed healing, or other diabetes-related oral problems noted by the clinician.
When to use this code
Use this code when the provider documents other specified diabetes mellitus and specifically links it to an oral complication. It is appropriate when the mouth condition is part of the record and not just a separate dental issue. Check documentation for the exact diabetes type and the oral manifestation.
Do not use for
Do not use this code for diabetes without an oral complication, or when the diabetes type is unspecified. Do not assign it if the oral problem is documented separately without a causal link to diabetes.
Coding tip
Confirm both the diabetes category and the oral complication in the provider note before assigning E13.63.
