the global period is determined by _______.
The Medicare Claims Processing Manual defines the global surgical package concept in Chapter 12, Section 40.1. The global period is defined for each surgical Healthcare Common Procedural Coding System (HCPCS) code.

This means that all services provided to a patient that included in the global package that provided during this period are considered integral to the global package.
