I am little confused about the use of external cause codes, Y92. Y93, and Y99 with poisonings. Here is what the guidelines say, but my answer key for my text book is assigning the Y codes for place of occurrence, activity, and status. The text book even has a note that says "recall that external cause, place, activity, and status codes are not applicable to poisoning, adverse effects, misadventures, or late effects" so I am confused as to why the answer key includes them as part of the correct answer.
From the guidelines:
Codes in categories T36-T65 are combination codes that include the substance that was taken as well as the intent. No additional external cause code is required for poisonings, toxic effects, adverse effects and underdosing codes.
No external cause code needed in certain circumstances
No external cause code from Chapter 20 is needed if the external cause and intent are included in a code from another chapter (e.g. T36.0X1- Poisoning by penicillins, accidental (unintentional)).
