ICD-10 Code E08.63 – Diabetes mellitus due to underlying condition with oral complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.63 – Diabetes mellitus due to underlying condition with oral complications
What it is
This code identifies diabetes that is caused by another underlying condition and is documented with oral complications. Use it when the record links the diabetes to a separate cause and notes a mouth-related complication.
Clinical signs
Clinical features vary; refer to documentation. Oral findings may include problems such as gum disease, mouth infections, or other diabetes-related oral changes when specifically documented by the provider.
When to use this code
Use E08.63 when the chart states diabetes mellitus due to an underlying condition and also documents an oral complication. The underlying condition should be identified elsewhere in the record when coding rules require it. If the oral problem is not clearly linked to the diabetes, check documentation before assigning this code.
Do not use for
Do not use this code for diabetes not caused by another condition, or for oral disorders without a documented diabetes link. If the record only says “diabetes” or does not specify the oral complication, check documentation.
Coding tip
Verify both elements: the underlying-condition diabetes and the oral complication must be documented to support E08.63.
