Is documenting the interpreter’s ID number a waste of time?

Hi everyone!

Whenever I consent a patient for a procedure using an interpreter I have to document the interpreter’s name and ID number. I have never seen this information get used for anything. I feel like a generic statement like “a professional interpreter was used during consent” should suffice. Does anyone have any interesting examples in which the interpreter’s ID wound up being useful for something? Or alternatively you forgot to document the interpreter’s ID number and created a problem?

Yes I realize that this is probably an extremely unimportant question.
