As of January 1, 2018 the US Centers for Medicare and Medicaid have approved the CPT code 36466- treatment for multiple incompetent truncal veins, same leg. We added this code to our medical software program but when it was sent electronically to clearinghouse, it was rejected as a code not recognized. Maybe the insurance companies need some time to update the new codes for 2018 but I'm reaching out to find out if anyone else is familiar with this code.
