Transcutaneous Electrical Nerve Stimulator (TENS)
DESCRIPTIONTranscutaneous electrical nerve stimulator (TENS) is an electronic device that applies electrical stimulation to the surface of the skin at the site of pain and has been used to relieve chronic intractable pain, post-surgical pain, and pain associated with active or post-trauma injury unresponsive to other standard pain therapies. TENS has also been used to treat dementia by altering neurotransmitter activity and increasing brain activity that is thought to reduce neural degeneration and stimulate regenerative processes.
TENS consist of an electrical pulse generator, usually battery operated, connected by wire to two or more electrodes, which are applied to the surface of the skin at the site of the pain.
Sympathetic therapy describes a type of electrical stimulation of the peripheral nerves that is designed to stimulate the sympathetic nervous system in an effort to "normalize" the autonomic nervous system and alleviate chronic pain. Unlike TENS or inferential electrical stimulation, sympathetic therapy is not designed to treat local pain, but is designed to induce a systemic effect on sympathetically induced pain.
POLICYTranscutaneous electrical nerve stimulation (TENS) is considered medically necessary for chronic intractable back pain (lumbar, cervical, or thoracic), where other modalities have failed.
Transcutaneous electrical nerve stimulation (TENS) is considered investigational for the management of chronic intractable or acute postoperative pain.
The use of TENS to relieve pain of labor and vaginal delivery is considered investigational.
The use of TENS for any other condition, including but not limited to the treatment of dementia and prevention of migraine headaches, is considered investigational.
Sympathetic Therapy, which is delivered using the Dynatron STS and Dynatron STS Rx device, is considered investigational.
POLICY EXCEPTIONSFor FEP subscribers, continued use of transcutaneous electrical nerve stimulation (TENS) may be considered medically necessary for treatment of refractory chronic pain (e.g., chronic musculoskeletal or neuropathic pain) that causes significant disruption of function when efficacy has been demonstrated in an initial therapeutic trial and compliance has been demonstrated in the therapeutic trial with the device used on a regular basis (e.g., daily or near daily use) throughout the trial period. Refractory chronic pain is defined in this policy as pain that causes significant disruption of function and has not responded to at least 3 months of conservative therapy, including nonsteroidal anti-inflammatory medications, ice, rest, and/or physical therapy.
Federal Employee Program (FEP) may dictate that all FDA-approved devices, drugs or biologics may not be considered investigational and thus these devices may be assessed only on the basis of their medical necessity.
Investigative service is defined as the use of any treatment procedure, facility, equipment, drug, device, or supply not yet recognized by certifying boards and/or approving or licensing agencies or published peer review criteria as standard, effective medical practice for the treatment of the condition being treated and as such therefore is not considered medically necessary.
The coverage guidelines outlined in the Medical Policy Manual should not be used in lieu of the Member's specific benefit plan language.
POLICY HISTORY8/2001: Approved by Medical Policy Advisory Committee (MPAC), Code Reference section completed, CPT code 64550 added, ICD-9 procedure code 93.39 added, HCPCS E0720-E0749, K0118 added
