Which modifier indicates a bilateral procedure?

The modifier that indicates a bilateral procedure is -50. This modifier is specifically used to signify that a procedure was performed on both sides of the body during the same session. In medical billing, using this modifier helps to ensure that providers are reimbursed appropriately for bilateral services, as it usually indicates that the procedure has been performed on paired organs or limbs.

Using this modifier alerts the payer to treat the procedure as one comprehensive service rather than two separate services, which is important for correct coding and billing practices. This assists in maintaining clarity in medical records and ensures that the healthcare provider's work is recognized for the additional complexity and effort involved.

In contrast, the other modifiers listed serve different purposes. Modifier -25 is used to indicate that a significant, separately identifiable evaluation and management service was provided on the same day as another procedure. Modifier -22 indicates increased procedural services when a provider has performed more than what is usually required for a procedure. Modifier -76 is used to signify that a procedure was repeated by the same physician or other qualified healthcare professional, typically on the same day. These modifiers serve distinct functions, and thus, they would not apply to indicate bilateral procedures.
