Just in case you missed it on the VisionWeb Blog:
Medicare has expanded the Multiple Procedure Payment Reduction (MPPR) policy and, effective January 1, 2013, will implement cuts to concurrent diagnostic eye services. If more than one test is performed on the same day, the payment for the technical component (TC) of the less expensive service will be reduced by 20 percent. The MPPRs do not apply to professional component (PC) services.
