64490 & 64493 for post operative pain

I code for anesthesia and I have a doctor that did a Thoracic Paravertebral nerve block; CPT code 64490, for post op pain. We are getting an LCD edit as we are using it for post op pain with ICD 9 - 338.18. When I pull the LCD edit, it only shows that it is valid for cervical and thoracic spondylosis. Any ideas on what nerve block code I should use in its place. I'm thinking that I should just use 62310 for the thoracic nerve block.

Thank you
