What does the -50 modifier indicate in Current Procedural Terminology?

The -50 modifier in Current Procedural Terminology indicates a bilateral procedure. This modifier is used to signify that a procedure was performed on both sides of the body during the same operative session. When coding for bilateral procedures, it's important to apply the -50 modifier to the appropriate CPT code to ensure that both sides are appropriately accounted for, which can affect billing and reimbursement.

Using the -50 modifier allows the healthcare provider to receive adequate compensation for performing the procedure bilaterally, rather than submitting two separate claims for each side, which could lead to confusion and potential denial of payment. This approach promotes clarity in the medical record and aligns with proper coding practices by indicating that the service performed was intended for both sides simultaneously.

Other options addressed different meanings that do not pertain to the -50 modifier. The multiple procedures aspect is indicated by a different set of modifiers, while unrelated procedures and reference laboratories are denoted by separate coding practices that cater specifically to each scenario.
