Level _____ codes were developed by Medicare carriers but are no longer available since HIPAA?

Level III codes were indeed developed by Medicare carriers to represent procedures, services, and supplies that were specific to certain regions. However, following the implementation of the Health Insurance Portability and Accountability Act (HIPAA), which set national standards for electronic health care transactions and privacy, these codes were phased out.

The transition aimed to streamline the coding process and create uniformity across the U.S. healthcare system. As a result, only Level I (CPT codes) and Level II (HCPCS codes for non-physician services) are now in use. Thus, the correct identification of Level III codes as being discontinued is directly tied to changes in regulatory requirements under HIPAA.
