ICD-10 Code E13.64 – Other specified diabetes mellitus with hypoglycemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.64 – Other specified diabetes mellitus with hypoglycemia
What it is
This code identifies diabetes mellitus due to another specified cause, complicated by hypoglycemia. Use it when the record shows a nonstandard diabetes type and low blood sugar, but not type 1, type 2, or gestational diabetes.
Clinical signs
Clinical features vary; refer to documentation. Typical hypoglycemia may include sweating, shakiness, confusion, hunger, or altered mental status, but you should code only when the provider documents the condition.
When to use this code
Use E13.64 when the chart documents “other specified diabetes mellitus” and hypoglycemia as a current complication. This is appropriate for encounters focused on low blood sugar in a patient with a specified non-type 1/non-type 2 diabetes. If the note does not clearly identify the diabetes category or the hypoglycemia, check documentation.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes with hypoglycemia. Also avoid it when hypoglycemia is listed without a documented diabetic relationship or when the diabetes type is unspecified.
Coding tip
Verify both the diabetes category and the hypoglycemia relationship in the provider note before assigning E13.64.
