What modifier should be used when the same procedure is performed multiple times during a single session?

The correct modifier for indicating that the same procedure is performed multiple times during a single session is -51. This modifier is specifically used in medical coding to signify that multiple procedures were performed during the same encounter. It helps to clarify that while the primary procedure is to be paid at the full established rate, any subsequent identical procedures may be reimbursed at a reduced rate.

Using -51 ensures that the insurance payer understands that multiple instances of the service or procedure occurred, which can affect reimbursement rates and the overall billing process. This is particularly important for accurate coding and ensuring that providers are correctly compensated for the services they deliver.

The other modifiers listed serve different purposes and are not suited for indicating multiple instances of the same procedure. For example, -50 denotes bilateral procedures, -32 refers to mandated services, and -26 indicates professional component services. Each of these modifiers addresses distinct scenarios not related to performing the same procedure multiple times within a single session.
