Bone Stimulator Billable Amount

Are Bone Stimulators, CPT Code 20979 and CPT Code 20974 billed per day as a rental? As a DME provider is it worth the investment?

re: Bone Stimulator Billable Amount

These codes are classified as a therapeutic procedure, not DME. Ultrasonic osteogenic stimulators are generally used and may be considered medically reasonable and necessary for the treatment of non-union fractures.
