What This Code Means

This code describes a serious condition where a patient with a specific type of diabetes (not Type 1 or Type 2) experiences dangerously low blood sugar levels that cause them to lose consciousness. This is a medical emergency requiring immediate treatment to restore blood sugar levels.

Coding Tips

• •Verify the diabetes type is documented as 'other specified' rather than Type 1 or Type 2, as this distinction is critical for correct code selection
• •Ensure documentation clearly indicates both hypoglycemia AND coma are present; if only hypoglycemia without coma exists, use E13.641 without the coma component instead

Clinical Significance

E13.641 identifies hypoglycemia with coma in other specified diabetes mellitus, representing a severe and potentially fatal acute complication. Hypoglycemic coma occurs when blood glucose drops critically low (typically below 40 mg/dL), causing loss of consciousness due to neuroglycopenia. This requires immediate glucose administration and is most commonly associated with insulin or sulfonylurea therapy.

Documentation Requirements

• ✓Documentation must confirm secondary diabetes, hypoglycemia with coma, and the clinical circumstances.
• ✓Blood glucose levels, the cause of hypoglycemia (medication-related, missed meals, excessive exercise), treatment administered, and resolution of coma should be documented.
