Which code type focuses on outpatient services like therapy?

The correct choice emphasizes the coding system specifically designed for outpatient services, particularly therapy-related services. C codes are utilized in the Healthcare Common Procedure Coding System (HCPCS) for reporting outpatient services, particularly those that do not fall under standard procedure codes and are often related to procedures done in an outpatient setting. This makes them appropriate for therapy services, which are typically provided outside of an inpatient context.

In contrast, other code types mentioned, such as A codes, B codes, and K codes, are not primarily focused on outpatient services. A codes are typically used for ambulance services, B codes are generally reserved for certain products and supplies, while K codes are often related to durable medical equipment. Thus, C codes are distinctively applicable to outpatient therapeutic services, making them the right choice in this scenario.
