ICD-10 Code E09.64 – Drug or Chemical Induced Diabetes Mellitus with Hypoglycemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.64 – Drug or chemical induced diabetes mellitus with hypoglycemia
What it is
This code identifies diabetes caused by a drug or chemical, with documented hypoglycemia. Use it when the diabetes is attributed to an external substance rather than primary diabetes.
Clinical signs
Clinical features vary; refer to documentation. Look for evidence of diabetes linked to a medication or chemical exposure, along with recorded low blood sugar episodes or symptoms consistent with hypoglycemia.
When to use this code
Use E09.64 when the provider clearly documents drug- or chemical-induced diabetes and hypoglycemia in the same encounter. It fits cases where the substance effect is the cause of the diabetic condition, not an incidental finding. Check documentation for the responsible agent and any linked adverse effect.
Do not use for
Do not use this code for primary diabetes with hypoglycemia or for hypoglycemia without documented drug- or chemical-induced diabetes. If the cause is unclear, check documentation.
Coding tip
Confirm the causal substance and the hypoglycemia documentation before assigning E09.64.
