Which modifier should be used for a bilateral procedure?

• A. 50
• B. 99
• C. 52
• D. 76

Answer: (A)

The modifier used for a bilateral procedure is referred to as the 50 modifier. This specific modifier indicates that a procedure was performed on both sides of the body during the same session. When a procedure can be done bilaterally, using this modifier informs payers that the service was provided on both sides, which can help in the appropriate reimbursement process. For example, if a surgeon performs a bilateral knee arthroscopy, indicating this with a 50 modifier communicates that both knees were treated in one operation. The other modifiers listed are used for different purposes: modifier 99 is for multiple modifiers, modifier 52 indicates a reduced service, and modifier 76 denotes a repeat procedure by the same physician. Therefore, they do not correctly signify a bilateral procedure, making the 50 modifier the appropriate choice in this context.
