The statement in the question, 'CPT codes 22840-22848 are modifier 62 exempt,' is true. Modifier 62 is used to indicate that a procedure was performed collaboratively by two surgeons. However, codes 22840-22848 are exceptions to this rule and are exempt from using modifier 62. These codes represent spinal fusion procedures that are commonly performed by two surgeons working together.
