Paravertebral Joint/Nerve Blocks - Diagnostic and Therapeutic

by  Find-A-Code
January 29th, 2018

According to Medicare article A50443, a facet joint level refers to the zygapophyseal joint or the two medial branch nerves innervating that zygapophyseal joint. 

Use CPT codes 64491 and 64492 in conjunction with 64490. Do not report CPT code 64492 more than once per day. Use CPT codes 64494 and 64495 in conjunction with 64493. Do not report CPT code 64495 more than once per day. For injection of the T12-L1 joint, or nerves innervating that joint, use 64493

The CPT codes 64490 and 64493 have a bilateral surgery indicator of "1." Thus, they are considered "unilateral" procedures and the 150% payment adjustment for the bilateral procedures applies.

Whether a paravertebral facet joint/nerve block is performed unilaterally or bilaterally at one vertebral level, use CPT code 64490 or 64493 for the first level injected. If a second, third or any additional level is injected unilaterally or bilaterally, use CPT codes 644916449264494 or 64495.
