Answer: Neurologists perform facet joint injections to relieve or control pain believed to be from a pars interarticularis defect.
You must know the injection level before coding the procedure, so ask the physician for more details. With complete information in hand, you should select a code from the 64470-64476 series (Injection, anesthetic agent and/or steroid, paravertebral facet joint or facet joint nerve ...), depending on the level.
