On April 1, 2013, the multiple procedure payment reduction will increase to 50% in all outpatient therapy settings who are reimbursed under the Medicare Physician Fee Schedule. The first unit of the CPT code that has the highest practice expense (PE) value will retain 100% of its value. Subsequent units of that CPT and all other CPT codes billed that day will have their PE value decreased by 50%. This will cause an approximate 6-9% reduction in your payments.
