ICD-10 Code E10.63 – Type 1 diabetes mellitus with oral complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.63 – Type 1 diabetes mellitus with oral complications
What it is
This code identifies type 1 diabetes mellitus with complications affecting the mouth. Use it when the record links the diabetes to an oral condition, such as gum disease or other mouth-related complications.
Clinical signs
Clinical features vary; refer to documentation. Oral findings may include periodontal disease, mouth infection, delayed healing, or other diabetes-related oral problems noted by the clinician.
When to use this code
Use E10.63 when the provider documents type 1 diabetes and a specific oral complication as related to the diabetes. The oral condition must be clearly linked in the medical record. If the note only mentions diabetes and a separate mouth problem without connection, check documentation.
Do not use for
Do not use this code for type 2 diabetes or for oral conditions not documented as diabetic complications. If the record does not specify the relationship, do not assume it.
Coding tip
Always verify that the oral complication is explicitly associated with type 1 diabetes before assigning E10.63.
