What modifier indicates subsequent surgical procedures performed by the same surgeon?

The modifier that indicates subsequent surgical procedures performed by the same surgeon is the -54 modifier. This modifier is used to identify surgical care that is provided by a surgeon in conjunction with a procedure that may have multiple visits or stages. When a procedure or service has more than one component, such as the surgical procedure itself and the subsequent follow-up care, the -54 modifier can be used to designate that the surgeon will be handling the surgical part only, while another provider may take over the post-operative care.

In this context, subsequent surgical procedures performed by the same surgeon refer to the ongoing management and care that could be associated with the surgical procedure performed, hence distinguishing it from modifiers used for other scenarios such as global surgical packages or unrelated surgical procedures.

The other modifiers listed serve different purposes: -55 refers to post-operative management provided by a different physician, -56 designates pre-operative care provided by a different physician, and -79 is used for unrelated procedures performed by the same physician during the post-operative period of a previous procedure. Each of these has distinct rules and applications that do not fit the scenario of subsequent surgical procedures by the same surgeon.
