I was contacted last week by a member who was denied payment by Medicare for 2 units of 64614 (Chemodenervation of muscle(s); extremity(s) and/or trunk muscle(s) {eg, for dystonia, cerebral palsy, multiple sclerosis}) of the right arm and right leg on the same visit. He has received payment in the past for billing 2 units of service in this circumstance. The member believed that policy existed supporting side of the body application for this code.
I have not located any information supporting a hemisphere concept for this code. In fact, it’s just the opposite. By defining the code use for “extremity(s) and/or trunk muscle(s),” the code language indicates that everything--whether 1 extremity or multiple extremities--is covered in 1 unit. Additionally, a CPT Assistant Q&A from February 2005 touched on this topic.
Q: Would it be appropriate to append modifier 50, Bilateral procedure, to CPT code 64614, Chemodenervation of muscle(s); extremity(s) and/or trunk muscle(s) (eg, for dystonia, cerebral palsy, multiple sclerosis), if both extremities are treated at the same session?
AMA Comment: From a CPT coding perspective, modifier 50 should not be appended to CPT code 64614 because the language of the code descriptor allows for chemodenervation of muscles of single or multiple extremities, as well as muscles of the trunk, if performed. This code should be reported only one time for chemondenervation of any of these areas within a single session.
Some payors may incorrectly pay for bilateral injection reported with modifier 50. Others may incorrectly pay for 2 units of 64614. However, the correct way to bill this service is to report 1 unit of 64614 for any/all extremities and/or muscles of the trunk.
