64450 and 77003

My physician has billed 64450 x 4 for a L5, S1, S2 and S3 nerve block. He wants to bill fluoro with 77003. When I check the CCI edits, I see where 77002 is bundled, but not 77003. He told me that 77003 was the correct fluoro code for SJI as the sacrum is part of the spine. Is it OK to bill 77003?

Thank you for your assistance.
