Thread: Radiofrequency ablation?

  1. #1

    Question Radiofrequency ablation?

    AAPC: Back to School
    I am trying to code an RFA for an ASC center and the physician states he performed an RFA on the left L4, L5, S1 and the S2 and S3 lateral nerves. I have been given conflicting information that I should code 64622, 64623x4. Also I have been informed it should be 64622, 64623, 64623, and 64640x2. Please help clarify.

    Thank you

    The paravertebral facet joint nerves do notinnervate the SI joint. There are no paravertebral facet jointsbelow the L5-S1 facet joint. Coding for performance of destruction of some branches that innervate the SI joint such as L5, S1, S2 and S3,which are not paravertebral facet joint nerves;so 64622 and 64623, is not correct, I believe.
    More accurately may be with 64640 or 64999., Depending on the procedure performed, upto dorsal ramus of the L5, 64622 and 64623 would appropriate. the remaining would go for 64640(Destruction by neurolytic agent; other peripheral nerveor branch) or an unlisted code, such as 64999 (Unlistedprocedure, nervous system) may be better.
    I hope this helps to calculate better.
