Ending in T are codes that identify what type of services?

The codes that end in "T" are specifically designated for emerging technologies, services, and procedures. These codes serve to identify new and innovative medical procedures or services that are not yet fully established within the standard coding systems, thus providing a unique designation to report their use. This coding category acknowledges advancements in healthcare and allows for appropriate documentation and reimbursement for novel interventions.

In contrast, the other options focus on categories that do not align with the designation of codes ending in "T." Routine services, history taking procedures, and surgical procedures are classified differently, reflecting established standards in medical coding rather than the innovative nature captured by the "T" codes. Hence, recognizing codes ending in "T" as related to emerging technologies is crucial for accurately reflecting modern medical practices.
