Question: Using the Resource-Based Relative Value Scale (RBRVS), what are the relative value units (RVUs) for modifiers 25, 26, 51, 52, 57, 59, and 80?

Answer: The official RBRVS assigns no RVUs to any modified code -- except for modifier 26 (Professional component) and modifier TC (Technical component).Remember, RVUs simply represent the procedures value.

Once you calculate your practice locations allowable, you can calculate the Medicare reduction for modifier 80 (Assistant surgeon) or modifier 51 (Multiple procedures).Under Medicare rules, a surgical assistant is paid 16 percent of the allowable, while the normal multiple procedure reduction is 50 percent of the allowable for the second through fifth additional procedure. Your payer may or may not reimburse a sixth additional procedure.

Modifier 59 (Distinct procedural service) has the same reduction as modifier 51. Why: When you apply modifier 59, you usually are applying it to secondary bundled procedures. In other words, modifier 59 tells the payer that the payer should not deny the procedure but treat it as any other multiple procedure.

You wont have any reduction for modifier 25 (Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service) or modifier 57 (Decision for surgery). Why: The payer will decide to either pay the E/M service or deny it.

Also, you cannot calculate the reduction for modifier 52 (Reduced services). Why: The payer will decide your reimbursement based on your physicians description of the proportion of work that he performed.
