Bench techs ordering patient tests and entering diagnosis codes

I work in a very toxic lab that has gotten significantly worse with new management. We've always been required to order tests based on doctors req's. This is in microbiology. We have a processing bench (separate from lab processing) that resolves errors, receives, orders tests, and plates. It is staffed by microbiology techs.

We're switching LIS systems, and the new system is less forgiving. Each test and order must be assigned by a diagnosis code. All management and leadership is pressuring us to enter these codes, put our names as the collector of the samples, and order the tests. They are refusing to train, provide resources, provide a chart or guide, and we've been told to "look it up" (i.e. Google it). We've been told "it's easy" to just copy what the doctor has written, but we immediately faced an issue of the doctor writing the wrong code for the diagnosis.

I am steadfast in refusal, but I am being made out to be a problem by leadership and by others in my department. Unfortunately, my coworkers are programmed to do anything that's being screamed at them, so they are quick to turn on me as well. I'm also so drained from everything else that has gone wrong with this system switch, and it's been difficult to catch my footing. That, coupled with feeling like the only sane person, is erroding at my resolve.

Can anyone provide a resource for why this is wrong? Am I incorrect that we shouldn't be doing this? Is this breaking some sort of regulation outside of just not being in my original job description? Sorry for the long post, I am so overworked and stressed, and this is just one item in the list of atrocities that has been our go-live.
