Non-ESRD claims for ESAs submitted without one of these modifiers will be rejected and must be corrected and resubmitted.
  • Report only one ESA modifier with each appropriate procedure code. If the ESA is submitted with multiple ESA modifiers, it will be rejected. 
  • Hematocrit and/or hemoglobin levels are required for the administration of ESAs or will be rejected.
  • For electronic claims, report the most recent hematocrit or hemoglobin level in Loop 2400 MEA segment. Specifically: MEA01=TR (for test results), MEA02=R1 (for hemoglobin) or R2 (for hematocrit), and MEA03=the test results. Enter the test results as follows: TR=test results, R1=hemoglobin or R2=hematocrit (a two position alpha-numeric element), and the most recent numeric test result (a three position numeric element (xx.x))
  • For paper claims, report the most recent hematocrit or hemoglobin level in Item 19 of the CMS-1500 claim form
