CPT modifier used for two surgeons. When two surgeons work together as primary surgeons performing distinct parts of a single reportable procedure, each surgeon should report his or her distinct operative work using the same procedure code and adding the modifier -62. If additional procedures (including add-on procedures) are performed during the same surgical session, separate codes may be reported without the modifier -62. If the cosurgeon assists in the performance of additional procedure(s) during the same surgical session, those services may be reported using separate procedure code(s) with modifier -80 or -81.
