You can't tell just from a code whether or not it is included in the global surgical package - the determination is not made by the type of code, but by whether the service is related vs. unrelated to the original procedure, whether it requires a return to the operating room, and whether it meets the definition of a staged/related procedure. Any code could be part of the package or not, depending on these factors.
Here's a link to the CMS publication on the Global Surgery package - I think this is the best resource out there for explaining this:
