Sympathetic Therapy for the Treatment of Pain Form

500 EXCHANGE STREET, PROVIDENCE, RI 02903-2699 MEDICAL COVERAGE POLICY | 1 (401) 274-4848 WWW.BCBSRI.COM EFFECTIVE DATE: 01|01|2026 POLICY LAST REVIEWED: 09|17|2025 OVERVIEW 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.
MEDICAL CRITERIA Not applicable PRIOR AUTHORIZATION Not applicable POLICY STATEMENT Medicare Advantage Plans Sympathetic therapy for the treatment of pain is not covered as the evidence is insufficient to determine that the technology results in an improvement in the net health outcome. Commercial Products Sympathetic therapy for the treatment of pain is not medically necessary as the evidence is insufficient to determine that the technology results in an improvement in the net health outcome. COVERAGE Benefits may vary between groups and contracts. Please refer to the appropriate section of the Benefit Booklet, Evidence of Coverage or Subscriber Agreement for applicable not medically necessary/not covered benefits/coverage. BACKGROUND Sympathetic therapy uses 4 intersecting channels of various frequencies with bilateral electrode placement on the feet, legs, arms, and hands. Based on the location of the patient’s pain and treatment protocols supplied by the manufacturer, electrodes are placed in various locations on the lower legs and feet or the hands and arms. Electrical current is then induced with beat frequencies between 0 and 1000 Hz. Treatment may include daily 1-hour treatments in the physician’s office, followed by home treatments, if the initial treatment is effective.
Unlike transcutaneous electrical nerve stimulation (TENS) or interferential electrical stimulation, sympathetic therapy is not designed to treat local pain, but is designed to induce a systemic effect on sympathetically induced pain.
Currently, there are no studies published in the peer-reviewed literature regarding sympathetic therapy, therefore there is no evidence to support its efficacy and the service is considered not medically necessary. CODING Medicare Advantage Plans and Commercial Products There is no specific CPT or HCPCS code for sympathetic therapy for the treatment of pain, therefore providers should report this service with an unlisted procedure code.
