Which modifiers are used to indicate procedures performed on the right or left side of the body?

The correct option highlights the use of specific CPT modifiers that denote procedures performed on either the right or left side of the body. Modifiers -RT (Right Side) and -LT (Left Side) serve a crucial role in accurately documenting the location of a procedure, ensuring that the billing reflects the precise nature of the services rendered.

Using these modifiers is particularly important in situations where the same procedure is performed on both sides of the body, as they help avoid confusion and ensure proper reimbursement. For example, if a surgeon performs a procedure on the right knee, using the -RT modifier clarifies that the service was localized to that side, which is vital for record-keeping and insurance billing.

In contrast, other modifier combinations mentioned do not specifically denote lateralization of procedures. For instance, -50 refers to bilateral procedures but does not individually specify right or left. Therefore, using -RT and -LT is the most effective way to distinctly communicate the service's location concerning the sides of the body.
