CPT® Code 20974

Electrical stimulation to aid bone healing, as described by CPT® Code 20974, refers to a noninvasive method employed to enhance the healing process of bones that may be compromised. While bone typically heals effectively on its own, certain conditions can hinder this natural process. For instance, inadequate blood circulation to the fracture site or the presence of scar tissue can impede healing. In such cases, electrical stimulation serves as a therapeutic intervention to promote bone repair. The noninvasive techniques utilized in this procedure include methods such as pulsed electromagnetic field (PEMF) therapy, where a coil is positioned on the skin or integrated into a cast over the affected area. This coil is connected to a treatment unit that generates an electrical current, creating an electromagnetic field that surrounds the fracture site, thereby facilitating healing. Another noninvasive approach involves the use of a capacitive coupling device, which employs two electrodes placed on the skin over the fracture. These electrodes connect to a battery-operated stimulation unit that delivers a low-voltage alternating current to stimulate the healing process. It is important to note that CPT® Code 20974 specifically pertains to noninvasive techniques, distinguishing it from CPT® Code 20975, which involves invasive methods where electrodes are directly implanted into the bone during an operative procedure.
