I'm new to coding so here is my scenario: the pt had a previous spinal fusion ( for proximal junction kyphosis) extended. Do I use M43.24 as my dx in M1021 or Z98.1? Thanks.
If you look up Z98.1, under the coding tips it states, "If spinal fusion has taken place, also use a code from M43.2-."
I've seen that too but I also have coders telling me not to use it so that was why I asked. Thanks for your input. Figuring this stuff out is crazy sometimes.
