Genicular coding

My billing/coding people are telling me that a three nerve genicular block can only be billed as a single nerve block, 64450, one unit. This seems like you should be able to bill 3 units or use -51 modifier, and get paid for 3 nerves Which is it? And, can you use 77002 or is that gone from all nerve blocks now?
