ICD-10 Code E13.649 – Other specified diabetes mellitus with hypoglycemia without coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.649 – Other specified diabetes mellitus with hypoglycemia without coma
What it is
This code identifies a form of diabetes mellitus that is not type 1 or type 2, with documented hypoglycemia but no coma. Use it when the record specifies another diabetes type and low blood sugar is present.
Clinical signs
Typical findings include symptoms of hypoglycemia such as sweating, shakiness, hunger, confusion, or weakness. Clinical features vary; refer to documentation, and confirm that coma is not present.
When to use this code
Use E13.649 when the provider documents other specified diabetes mellitus and also notes hypoglycemia without coma. It fits encounters where the low glucose episode is part of the diagnosis or assessed during the visit. Do not assume the diabetes type; code only what is documented.
Do not use for
Do not use this code if the patient has hypoglycemia with coma, because a different code applies. Do not use it when diabetes type is unspecified or when documentation does not support hypoglycemia.
Coding tip
Check that the record names the diabetes category and clearly states hypoglycemia without coma before assigning E13.649.
