I believe the information you recieved for the 8 facet injections in the neck was incorrect.. I bill facet injections all the time and have no problem w/ recieving payment. CPT codes 64475 & 64476 are for facet injections to the lumbar spine, and the facet injections your Dr gave was to the C/S. The correct way to code this is:
64470 RT
64470 LT
64472 RT
64472 LT
64472 59RT
64472 59LT
64472 59RT
64472 59LT
I Normally only bill a max of 6 injections at one time, our Dr's have never given 8 at once. Also, the correct HCPCs code for depo-medrol is J1030.
I hope this helps
