We are having a debate in the office and I was hoping to find some assistance here.

If a facet nerve block (64490-64495) or ablation spans two spinal regions, since the description in the additional level CPT codes indicate the regions (ie 64491-64492 indicate cervical or thoracic and 64494-64495 indicate lumbar or sacral), does that mean, you would jump to the primary code of the next spinal region for the additional levels?

For example, T11-L2 facet nerve block. Would it be 64490 for T11-12, 64491 for T12-L1, & 64493 for L1-2 or should the L1-2 be coded as 64492?

The only guideline I can find is in the NCCI where it talks about procedures done at contiguous spine levels but it mentions if the additional level code doesn’t indicate the spine region that you would use the add on code rather than another primary code.

Thanks!
 
I'm not an expert when it comes to spinal coding. However, there is a guideline in the 2018 CPT book (pg 413) that states "For paravertebral facet injection of the T12-L1 joint, or nerves innervating that joint, use 64490". I'm thinking that, for your scenario, this should be coded as 64490 (T11-T12), 64491 (T12-L1) and 64493 (L1-L2).
