I work for an anesthesia group. I have come across a lot of denied nerve blocks. ( 64445, 64446, 64447, ect) We billed 64445 59 LT 64447 59 LT. UHC MCR denied, I called and they said they have removed modifier 59 from their list. ????? I also was told that I was either needing another modifier or I needed to remove a modifier. I asked if they followed MCR guidelines, she said yes. I found several claims paid by MCR with the 59 modifier. I cannot find anything specific on the modifiers I should use to bill out the 2 codes. Can you help me with this mystery? THX Desperate to Know
