ICD-10 Code E09.65 – Drug or chemical induced diabetes mellitus with hyperglycemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.65 – Drug or chemical induced diabetes mellitus with hyperglycemia
What it is
This code identifies diabetes caused by a drug or chemical, with documented hyperglycemia. Use it when the elevated glucose is linked to the offending substance rather than primary diabetes.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records note hyperglycemia, new or worsened diabetes, and a causal medication or chemical exposure.
When to use this code
Use E09.65 when the provider documents drug- or chemical-induced diabetes and specifies hyperglycemia. It fits cases where a medication, toxin, or other chemical is identified as the cause. Code the adverse agent or exposure as instructed in the record and coding guidelines.
Do not use for
Do not use this code for primary type 1 or type 2 diabetes, or for drug-induced diabetes without hyperglycemia. If the documentation does not clearly link the condition to a substance, check documentation.
Coding tip
Confirm both the cause and the hyperglycemia in the provider note before assigning E09.65.
