ICD-10 Code E09.9 – Drug or chemical induced diabetes mellitus without complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.9 – Drug or chemical induced diabetes mellitus without complications
What it is
This code identifies diabetes caused by a drug or chemical exposure, without documented complications. Use it when the record links hyperglycemia or diabetes to a medication or other chemical agent.
Clinical signs
Clinical features vary; refer to documentation. You may see persistent elevated glucose, new-onset diabetes after exposure, or worsening glycemic control attributed to the offending agent.
When to use this code
Use E09.9 when the clinician documents drug- or chemical-induced diabetes and does not report any complication such as ketoacidosis, kidney involvement, or neurologic effects. It also fits cases where the note clearly ties diabetes to a medication or toxin but leaves complications unspecified.
Do not use for
Do not use this code for type 1, type 2, gestational, or postprocedural diabetes. If a complication is documented, choose the more specific E09 code instead.
Coding tip
Link the diabetes to the causative drug or chemical in the documentation before assigning E09.9.
