Bone healing service
About 20974: Noninvasive electrical bone stimulation
Report noninvasive electrical stimulation used to support bone healing, such as for a delayed fracture union or a spinal fusion site.
This service involves applying electrical stimulation externally to support bone healing, without implanting an electrode. It is used in situations such as delayed fracture healing or to support a spinal fusion site. Orthopedic and spine practices commonly manage this therapy, with the stimulation delivered at the treatment site using an external device.
Report 20974 for noninvasive electrical stimulation, not an implanted stimulation approach or low-intensity ultrasound. Documentation should identify the bone or fusion site, the healing concern, and the noninvasive electrical service provided. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this service. Medicare does not pay an assistant at surgery for this code, and co-surgeon and team-surgery billing are not permitted.
