What descriptor is typically associated with "G" codes in HCPCS Level II?

The descriptor typically associated with "G" codes in HCPCS Level II is that they are temporary codes for specific services or procedures. G codes are primarily used to identify specific professional services that are not adequately represented by existing codes, including transportation, certain therapy services, and other procedures that may arise based on advances in medical technology or shifts in clinical practice.

These codes are assigned to various healthcare services for which coding might be required on a short-term basis, especially for new techniques and technologies, thus providing a mechanism for capturing and reporting these services while establishing whether they should receive a permanent code in the future.

By design, these codes help in the documentation and reimbursement processes, ensuring that services rendered can be specifically coded, facilitating their tracking and payment in the healthcare system. The temporary nature of "G" codes underscores the ongoing evolution of healthcare services and coding requirements.
