What does the modifier 58 indicate in the CPT manual?

The modifier 58 in the CPT manual indicates a staged or related procedure or service that is performed during the postoperative period of a previous procedure. It signifies that the subsequent procedure is intentional and planned, rather than a complication or unplanned service. This modifier helps to clarify the relationship between the procedures for billing and coding purposes. It is important for ensuring appropriate reimbursement and accurate reporting of surgical care.
