Type 2 diabetes mellitus with hypoglycemia with coma

This code signifies a patient diagnosed with type 2 diabetes who is experiencing a dangerously low blood glucose level (hypoglycemia) that has progressed to a state of unconsciousness (coma). It indicates a severe, acute complication of their diabetes management.

Apply this code when documentation clearly states type 2 diabetes and an episode of hypoglycemic coma. Supporting documentation includes physician notes detailing the patient's diabetic status, blood glucose readings indicating severe hypoglycemia, and a description of the comatose state.

• Always code the underlying type 2 diabetes first, followed by this complication.
• Ensure documentation specifies "coma" and not just severe hypoglycemia without loss of consciousness.
• Distinguish from hypoglycemic shock without coma (E11.649) or other diabetic complications.
