Q & A with Dr. Z: Sacroiliac Joint Injection

by David Zielske, MD, CIRCC, COC, CCVTC, CCC, CCS, RCC

Does the 2020 code 64451 (nerves innervating the sacroiliac joint) replace the 27096 when the injection states “into the SI joint,” or is the code used in place of billing the S1, S2, S3 as peripheral (64450)?

No, it does not replace CPT code 27096 when an SI joint injection is performed. Code 64451 is reported for the injections of the nerves that innervate the SI Joint, such as the S1, S2, S3 injections you mention.
