CPT code for branch block ablation

    Default CPT code for branch block ablation

    Can anyone tell me what the appropriate CPT code(s) would be for a medial branch block with radiofrequency ablation?

    Thank you in advance!

    Below is from AMA CPT Changes 2012, these codes are broken out between cervical/thoracic (64633, 64634) and lumbar/sacral (64635, 64636).

    64633 represents the primary procedure for the first cervical or thoracic level, which would be abstracted from the procedure note based on the facet joint level or the medial branches that innervate that joint. As seen below, whether for example, it states radiofrequency ablation of L3, L4, L5 or L4-L5 and L5-S1, you are counting by facet joint level, not individual medial branches. RT or LT modifier or 50 modifier should be used. The T12-L1 joint would be a thoracic level. The add on codes (64634 or 64636) would represent additional facet joint levels addressed.

    ......the unit of service is a single facet joint in new codes 64633, 64634, 64635, and 64636, rather than a vertebral level. If both facet joints at the same vertebral level are treated, then the parent code (64633 or 64635) should be reported with modifier 50 appended. It is important to note that the number of nerves injected for a single facet joint does not affect code selection. Therefore, the new codes indicate "nerve(s)" in the descriptors.....

    Depending on how many levels are ablated it would be 64635 64636. Fluoro is bundled into these codes.
