ICD-10 Code E09.649 – Drug or chemical induced diabetes mellitus with hypoglycemia without coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.649 – Drug or chemical induced diabetes mellitus with hypoglycemia without coma
What it is
This code identifies diabetes caused by a drug or chemical, with documented hypoglycemia but no coma. Use it when the record links the low blood sugar to the induced diabetic condition.
Clinical signs
Patients may have typical hypoglycemia findings such as sweating, shakiness, confusion, or weakness. Clinical features vary; refer to documentation for the specific episode and the causal agent.
When to use this code
Use E09.649 when the provider documents drug- or chemical-induced diabetes mellitus and also documents hypoglycemia without coma. The chart should support the relationship between the medication or chemical exposure and the diabetic condition.
Apply this code when the encounter focuses on the hypoglycemic complication of the induced diabetes. If the cause, diabetes type, or presence of coma is unclear, check documentation before coding.
Do not use for
Do not use this code for hypoglycemia without diabetes, or for diabetes with coma. Also avoid it when the diabetes is not documented as drug or chemical induced.
Coding tip
Verify both the induced diabetes diagnosis and the hypoglycemia complication are explicitly documented before assigning E09.649.
