ICD-10 Code E13.641 – Other specified diabetes mellitus with hypoglycemia with coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.641 – Other specified diabetes mellitus with hypoglycemia with coma
What it is
This code identifies hypoglycemia with coma in a patient who has other specified diabetes mellitus. Use it when the record links the coma to low blood sugar and specifies this diabetes category.
Clinical signs
Clinical features may include loss of consciousness, severe confusion, seizure activity, or inability to awaken, with documentation indicating hypoglycemia. Clinical features vary; refer to documentation.
When to use this code
Use E13.641 when the provider documents other specified diabetes mellitus and states that the patient had hypoglycemia with coma. The coma should be attributed to the hypoglycemic episode, not another cause. Check documentation if the diabetes type or the relationship is unclear.
Do not use for
Do not use this code for hypoglycemia without coma, or when coma is due to another condition. If the chart does not support other specified diabetes mellitus, choose the more accurate diabetes code.
Coding tip
Confirm both the diabetes category and the coma linkage to hypoglycemia before assigning E13.641.
