How should you code multiple procedures during a single operative session?

When coding multiple procedures performed during a single operative session, applying modifier 51 to each secondary procedure is the correct approach. Modifier 51 is specifically intended to indicate that multiple procedures were performed by the same professional in one session. It allows for the distinction to be made between the primary procedure and any additional procedures that were performed.

Using modifier 51 tells payers that the services rendered are related but distinct, ensuring proper reimbursement for each procedure performed. It’s essential to apply this modifier only to the additional procedures following the primary procedure to avoid confusion regarding billing and reimbursement.

Using only one code would not accurately reflect the work done, as it would imply that only one procedure was performed. Applying modifier 50, which indicates a bilaterally performed procedure, is also incorrect unless both sides of the body were actually involved in the procedures. Lastly, using both modifiers 32 and 51 together is not a recommended practice, as modifier 32 refers to mandated services rather than indicating multiple procedures. Each modifier serves a different purpose, and in this case, only modifier 51 is necessary for indicating multiple procedures within a single operative session.
