Which code is typically used for a procedure that is performed on both sides of the body?

A bilateral modifier is used to indicate that a procedure has been performed on both sides of the body. In coding, this modifier is typically applied to the procedure codes in order to signify that the treatment was bilateral instead of unilateral. This is important for accurate billing, as procedures performed on both sides may have different reimbursement implications compared to those done unilaterally.

When using a bilateral modifier, it clarifies the extent of the procedure to insurers, ensuring proper payment and documentation. Additionally, applying this modifier can prevent confusion about whether separate procedures were performed, which may require distinct coding.

In contrast, unilateral modifiers are meant for procedures performed on one side, global codes refer to a comprehensive package of services surrounding a procedure, and diagnostic codes are used to identify the reasons for the surgery rather than the procedure itself. Thus, the bilateral modifier is the most appropriate choice for denoting procedures conducted on both sides of the body.
