Nondiabetic hypoglycemic coma

This code signifies a severe neurological emergency characterized by profound unconsciousness resulting from critically low blood glucose levels in an individual who does not have diabetes. It can be triggered by various factors, including medication side effects, excessive insulin production, or other underlying conditions.

Apply this code when documentation clearly indicates a patient presenting with a coma directly attributed to hypoglycemia, and there is no underlying diagnosis of diabetes mellitus. This includes cases of iatrogenic hypoglycemia (e.g., from insulin or oral hypoglycemic agents in a nondiabetic) or endogenous hyperinsulinism leading to coma.

• Differentiate carefully from diabetic hypoglycemic coma (E11.649, E13.649, etc.), which requires a confirmed diagnosis of diabetes.
• Always review medication lists and patient history to rule out diabetes before assigning this code.
• Consider additional codes for the underlying cause of the nondiabetic hypoglycemia, if known and documented.
