The global surgery status indicator 'YYY' refers to which type of codes?

The global surgery status indicator 'YYY' is designated for unlisted procedure codes. This designation indicates that the procedure does not have a specific code within the current coding system, and as such, it must be reported using an unlisted code. This type of code is used when a procedure is performed that does not have a defined or specific CPT code, thereby allowing the healthcare provider to describe the service more accurately.

Using unlisted codes requires careful documentation and often necessitates a detailed description of the procedure performed, as well as justification for why a specific code could not be used. This is crucial for proper reimbursement and for maintaining compliance with coding guidelines.

In contrast, other types of codes such as standard procedure codes, add-on codes, and post-operative codes each have specific purposes within the coding system, which does not correspond to the 'YYY' status indicator. Standard procedure codes indicate defined surgical procedures; add-on codes are supplementary codes that cannot be reported alone and are used to further describe a service; and post-operative codes refer to the care provided during the global surgery period following a specific procedure. Therefore, unlisted procedure codes are accurately represented by the status indicator 'YYY'.
