HCC Category Mapping

What This Code Means

A type of diabetes (not type 1 or type 2) with low blood sugar that does not cause loss of consciousness.

Coding Tips

• •Verify that hypoglycemia is present but the patient did not lose consciousness; if coma occurred, use E13.641 instead
• •Document the severity and symptoms of the hypoglycemic episode

Clinical Significance

E13.649 captures hypoglycemia without coma in other specified diabetes mellitus. Hypoglycemic episodes, while not resulting in loss of consciousness, can cause significant symptoms including confusion, diaphoresis, tremors, palpitations, and seizures. Recurrent hypoglycemia may lead to hypoglycemia unawareness, paradoxically increasing the risk of severe future episodes.

Documentation Requirements

• ✓The provider must document secondary diabetes, the hypoglycemic episode, and confirm that coma did not occur.
• ✓Blood glucose levels, symptoms, precipitating factors, treatment, and any medication adjustments should be recorded.
