Type 1 diabetes mellitus with hypoglycemia with coma

This code describes a patient with Type 1 diabetes who is experiencing a severe hypoglycemic episode that has progressed to a state of unconsciousness. This represents a critical complication of diabetes management, indicating dangerously low blood glucose levels affecting brain function.

Use this code when documentation clearly states Type 1 diabetes and a diagnosis of hypoglycemia with an associated comatose state. This typically occurs in emergency settings or during acute inpatient care where the patient presents with altered mental status due to severe low blood sugar.

• Always confirm the type of diabetes (Type 1 vs. Type 2) as this significantly impacts code selection.
• Ensure documentation explicitly states "coma" or a similar term indicating unconsciousness due to hypoglycemia.
• Sequence this code as the principal diagnosis if it is the primary reason for the encounter, followed by codes for any associated complications or treatments.
