My doc who is credentialed & certified as a FP doc wants to read spirometry tests. Can anyone advise if Medicare has any special guidelines pertaining to who can read spirometry tests (i.e., do you have to be certified as CRT or other)? Thanks for your help! I did check the Medicare site for my area and printed off the LCDs pertaining to 94010 & I am not seeing it in there. Any direction would be greatly appreciated.
