When an Insulin Pump Malfunctions Leading to Overdosing, Select the Appropriate

When an insulin pump malfunctions leading to overdosing, select the appropriate reporting and sequencing of resulting conditions:

A) code first the appropriate diabetes code, then the mechanical complication due to the insulin pump, then poisoning by insulin, then the reason for the pump's presence, and any additional codes for conditions resulting from the overdosing
B) code first the mechanical complication due to the insulin pump, then poisoning by insulin, the appropriate diabetes code, and any additional codes for conditions resulting from the overdosing
C) code first the reason for the pump's presence, then poisoning by insulin, then the mechanical complication due to the insulin pump, the appropriate diabetes code, and any additional codes for conditions resulting from the overdosing
D) code first conditions resulting from the overdosing, then the mechanical complication due to the insulin pump, then the reason for the pump's presence, then poisoning by insulin, followed by the appropriate diabetes code
