What This Code Means

Type 1 diabetes with dangerously low blood sugar levels that have caused the patient to lose consciousness.

Coding Tips

• •This is an emergent condition requiring immediate documentation of the hypoglycemic episode and treatment provided
• •Verify whether the coma was resolved or if the patient remained unconscious at the time of coding

Clinical Significance

Type 1 diabetes mellitus with hypoglycemia with coma is a life-threatening acute complication where severely low blood glucose causes loss of consciousness. This represents a medical emergency requiring immediate intervention with intravenous dextrose or glucagon administration. Hypoglycemic coma in Type 1 diabetes is most commonly caused by insulin overdose, missed meals, or excessive physical activity, and indicates a need for intensive diabetes management reassessment.

Documentation Requirements

• ✓Documentation must clearly state hypoglycemic coma occurred in a patient with Type 1 diabetes, including blood glucose levels at the time of the event, the duration of unconsciousness, treatment administered, and clinical response.
• ✓The precipitating cause should be identified when possible.
• ✓Emergency department or inpatient records should document the level of consciousness using a validated scale.
