i have a procedure where the physician does an injection "outside of the paraspinal process"

Procedures
Paracervical block: After chlorhexidine preparation approximately 3 mL of 0.5% bupivacaine with epinephrine was injected approximately 2 cm to either side the C7 spinous process.

I have been advised to use 62320 which i don’t agree with b/c it does not specify the location exactly in the vertebrae and the documentation seems to be lacking for what is included in carrying out the procedure. i have concluded this is either 20552, unlisted or nothing. The provider did state "this is not a nerve block, per se". SO what is it if anything??

thank you!
