Question:
We had a patient who came in for a nerve block 3 days ago and came back in today and my physician performed another nerve block.  Since this procedure has a 10-day global period do I report Modifier 58 to 64450 for today’s block?

Answer:
CPT code 64450 (Injection, anesthetic agent; other peripheral nerve or branch) has 0 global days so you would report 64450 without a modifier since the global day is 0.
