A new modifier may be forthcoming to distinguish bypassing CCI from bypassing MPPR. CMS released the 2013 Medicare Physician Fee Schedule (MPFS; final with comment period) for services furnished on or after January 1. Not surprisingly, the American College of Radiology (ACR) is speaking up about the expansion of the Multiple Procedure Payment Reduction (MPPR). The MPPR applies to designated imaging services and reduces reimbursement for second and subsequent imaging services at the same session. The 2013 MPFS states Medicare will now "apply the MPPR to both the PC and the TC of advanced imaging procedures One of the reasons CMS gives is that "application of the imaging MPPR to physicians in the same group practice will ensure that there is no financial incentive for physicians in a group practice to change their behavior to split imaging interpretation services for a beneficiary among different physicians in the group." ACR response: Coding challenges: The challenges boil down to: (1) Lack of a clear definition for "same session" (2) Inability to distinguish between bypassing MPPR and bypassing CCI edits when using modifier 59 ( CMS responded in the MPFS: "We are aware of the conflict between use of modifier 59 for CCI edits and for purposes of bypassing the MPPR when multiple procedures are furnished. We are considering creating a new modifier for the MPPR to resolve this problem. In creating a new MPPR modifier, we would refine the definition of what constitutes a session." Resource:
