Can anyone help me on coding x-rays during a global period. Should they be coded as follows: Ex: TKA and on fu they did an x-ray to make sure everything is okay.

Z98.890
73560 – LT – 58
99024

Or is this part of the Global Package does it get a modifier 58 or not.

I just started coding x-rays and I am not sure.

Any help is appreciated.

Thank you,
LLR
