ICD-10 Code E09.63 – Drug or chemical induced diabetes mellitus with oral complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.63 – Drug or chemical induced diabetes mellitus with oral complications
What it is
This code identifies diabetes caused by a drug or chemical, with oral complications affecting the mouth. Use it when the record links the diabetes to an external substance and documents a mouth-related complication.
Clinical signs
Clinical features vary; refer to documentation. Oral complications may include problems in the mouth that are specifically tied to the diabetic condition, such as infection, inflammation, or other oral disease noted by the clinician.
When to use this code
Use E09.63 when the provider states the diabetes is drug or chemical induced and also documents an oral complication. The record should support both the cause of diabetes and the mouth-related manifestation. If the causal agent or oral finding is unclear, check documentation before coding.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes. Also avoid it when oral problems are present but there is no documented drug- or chemical-induced diabetes connection.
Coding tip
Code the causative substance and any additional manifestation codes only if the documentation supports them.
