Poisn by insulin and oral hypoglycemic drugs, undet, init

This code signifies an adverse event involving insulin or oral hypoglycemic medications where the intent (accidental, intentional self-harm, assault) cannot be determined. The patient is experiencing the initial effects or treatment for the poisoning.

This code is appropriate when a patient presents with symptoms of hypoglycemia or hyperglycemia due to insulin or oral antidiabetic drug exposure, and the clinician cannot definitively ascertain if the exposure was accidental, intentional, or due to an assault. It is used for the initial encounter for this poisoning event.

• Always assign an additional code for the specific adverse effect or manifestation of the poisoning (e.g., hypoglycemia, coma).
• Do not use this code if the intent of the poisoning is known; instead, select the appropriate T38.3X1-T38.3X3 code.
• Ensure the "A" seventh character for initial encounter is used only for the period when the patient is receiving active treatment for the poisoning.
