In Current Procedural Terminology, what signifies that multiple procedures may not include a more serious procedure?

The use of the -51 modifier is the correct choice because it specifically indicates that multiple procedures are being performed during the same session. This modifier is applied to the secondary procedural codes to show that they are separate and distinct from the primary procedure billed.

When multiple procedures are performed, the -51 modifier helps to signify that these additional procedures are not bundled into the highest level of service provided. This is important for proper billing, as it ensures that each procedure is accounted for and reimbursed appropriately, without implying that one is included in the other. Therefore, when using the -51 modifier alongside other procedure codes on a claim, it clearly communicates to the payer that multiple procedures exist in the same session and that they should not be considered part of a more serious or primary procedure.

Other options do not convey this intent. The -79 modifier is utilized for procedures performed on the same area during the postoperative period but is unrelated to the primary procedure. Multiple coding without modifiers does not specify the relationship between the procedures, potentially leading to confusion during billing. Referral to a different facility does not relate to multiple procedure billing practices and is focused more on the transfer of care than on coding specifics.
