Below displays that Aetna, Cigna, United HealthCare state they do not cover epidural injections utilizing ultrasound guidance. I believe you will find this with Blue Cross Blue Shield also per the specific policies that you bill. Additionally, Medicare released in the 2015 final rule for physician fee schedule that image guidance is not separately reportable with epidural injections.
"Aetna considers ultrasound guidance of epidural injections experimental and investigational because of insufficient evidence of its effectiveness."

"The use of ultrasound guidance for epidural steroid injection(s) and facet joint injection(s) is unproven and not medically necessary. There is insufficient clinical evidence regarding its safety and/or efficacy in published peer-reviewed medical literature. The available published evidence for ultrasound guidance for epidural and facet injections is limited to a small feasibility study and a cadaver study"

"After considering comments received, we are finalizing CPT codes 62310, 62311, 62318, and 62319 as potentially misvalued, finalizing the proposed RVUs for these services, and prohibiting separate billing of image guidance in conjunction with these services."
