What does the term "bundling" refer to in CPT coding?

Bundling in CPT coding refers specifically to the practice of grouping related services under one comprehensive code. This approach simplifies billing and documentation by consolidating multiple procedures or services that are typically performed together into a single code. For example, a surgical procedure that routinely includes pre-operative, intra-operative, and post-operative care might be represented by one bundled code, rather than having separate codes for each individual service. This not only reduces administrative burden but also helps in accurately reflecting the nature of the services provided, ensuring a more straightforward billing process.

In contrast, the other options address different aspects of coding or billing practices that do not align with the concept of bundling. Thus, the focus on grouping related services into one code is what specifically defines the practice of bundling in CPT coding.
