  • If only one NIHSS score is documented within the first 36 hours following initiation of IV thrombolytic (t-PA) therapy and no other NIHSS score(s) are available for comparison, enter the value for that score.
  • If multiple scores are documented within the first 36 hours following initiation of IV thrombolytic (t-PA) therapy, select the highest score.
    EXAMPLES:
    • NIHSS Score is 10 at 1500 and 20 at 2300. Both scores are documented following the initiation of IV thrombolytic therapy. Select NIHSS score of 20.
