Guidelines and Instructions
For dates of service prior to July 1, 2019, submit this modifier only for residents of a skilled nursing facility (SNF) who are in a Part A covered stay when it has been determined that:
  • The patient is entitled to Medicare based on End Stage Renal Disease (ESRD)
  • The test is related to the dialysis treatment for ESRD
  • The test was ordered by a doctor providing care to patients in the dialysis facility
