ICD-10 Code E09.01 – Drug or chemical induced diabetes mellitus with hyperosmolarity with coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.01 – Drug or chemical induced diabetes mellitus with hyperosmolarity with coma
What it is
This code identifies diabetes caused by a drug or chemical, complicated by hyperosmolarity and coma. Use it when the record links the condition to an external substance rather than primary diabetes.
Clinical signs
Clinical features vary; refer to documentation. The chart should support hyperosmolarity with coma and a documented drug- or chemical-induced diabetic state.
When to use this code
Use E09.01 when the provider states that a medication or chemical has caused diabetes and the patient has hyperosmolarity with coma. You should code it only when both the induced diabetes and the coma complication are documented together.
Do not use for
Do not use this code for primary diabetes with hyperosmolar coma, or when coma is not documented. Check documentation if the cause is unclear or if another diabetes type is specified.
Coding tip
Verify the causal agent and the coma complication in the note before assigning E09.01.
