I am a coder for a lab. We really don’t do the coding here, its all sent to us from the provider and we code what they tell us to code. So i feel like I am losing a lot of my knowledge, and I am now second guessing myself. Please help.

-if insurance denies for a DX issue, i will call and see if they have anymore codes to add and resubmit. If none i have to take adjustment.

-Occasionally i will get a claim that will deny bc there are screening codes along with a DX code and they will not process with both, so I have been told to remove the Z codes and resubmit, is this ok to do?

-I work for a lab that does specialized testing, and I will get an order from the provider and they will list 10 plus codes with DX that do not relate to the testing done. Do I have to list all possible codes they have provided? Like acne, when we are doing testing for non related things?

Sorry. I just want to make sure this is all done correctly!
