Which modifier is used to indicate multiple procedures that are performed during the same session?

Modifier 51 is specifically used to indicate that multiple procedures were performed during the same session by the same provider. This modifier is appended to the additional procedures to demonstrate to the payer that these procedures were not separate, distinct, or unrelated rather, they were part of a series of services provided in one encounter.

The use of Modifier 51 helps in the accurate processing of claims, allowing for proper compensation for multiple procedures performed in a single visit. It is essential in billing practices to ensure that the provider is not penalized or underpaid when multiple procedures are needed for the same patient at one time.

Modifier 33 is associated with preventive services and does not pertain to multiple procedures. Modifier 47 indicates a procedure that was performed with anesthesia and is not related to indicating multiple procedures. Modifier 50 refers to bilateral procedures and is used when the same procedure is performed on both sides of the body, not multiple different procedures.
