Drug-induced hypoglycemia without coma

This code signifies a state of abnormally low blood glucose levels that is directly caused by a medication, without the patient losing consciousness. It indicates an adverse drug effect leading to symptomatic hypoglycemia. The patient experiences symptoms such as shakiness, sweating, or confusion, but remains awake and responsive.

Use this code when documentation clearly links a patient's hypoglycemic episode to a prescribed or illicit drug, and the patient did not enter a comatose state. This is typically seen with antidiabetic medications (e.g., insulin, sulfonylureas) when dosage is too high or food intake is insufficient, or with other medications known to affect glucose metabolism. Documentation should specify the drug implicated and confirm the absence of coma.

• Always identify the specific drug causing the hypoglycemia using an external cause code (T36-T50 with a 5th or 6th character indicating adverse effect).
• Distinguish carefully from hypoglycemia due to diabetes (E11.649, E10.649, etc.) or other non-drug causes.
• Ensure documentation explicitly states "without coma" or describes the patient as awake and alert during the hypoglycemic event.
