ICD-10 Code E11.64 – Type 2 diabetes mellitus with hypoglycemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.64 – Type 2 diabetes mellitus with hypoglycemia
What it is
E11.64 identifies type 2 diabetes mellitus when the patient has hypoglycemia linked to the diabetes or its management. Use it when the record clearly shows low blood glucose in the setting of type 2 diabetes.
Clinical signs
Clinical features vary; refer to documentation. Hypoglycemia may be documented by symptoms such as shakiness, sweating, confusion, or other signs of low blood sugar, but you should code only when the provider documents the condition.
When to use this code
Use E11.64 when the clinician documents type 2 diabetes with hypoglycemia, including episodes related to diabetes treatment or diabetes itself. If the chart does not clearly link the low glucose event to type 2 diabetes, check documentation before assigning this code.
Do not use for
Do not use this code for type 1 diabetes, gestational diabetes, or unspecified hypoglycemia without a documented type 2 diabetes link. Check documentation if the record only mentions abnormal glucose or a suspected low blood sugar episode.
Coding tip
Assign the code only when the provider documents hypoglycemia with type 2 diabetes; otherwise, query for clarification.
