Medical policy: H-Wave Electrical Stimulation

Policy number: MP 6.049

Effective date: 4/1/2026

Policy

The use of H-wave stimulation is considered investigational for all indications, including but not limited to:

• Treatment of pain
• Wound healing
• Post-operative treatment to improve function and/or range of motion

There is insufficient evidence to support a general conclusion concerning the health outcomes or benefits associated with this procedure.

Description/background

H-wave stimulation is a form of electrical stimulation that differs from other forms of electrical stimulation, such as transcutaneous electrical nerve stimulation (TENS), in terms of its waveform. H-wave stimulation has been used for the treatment of pain related to a variety of etiologies, such as diabetic neuropathy, muscle sprains, temporomandibular joint dysfunctions, or reflex sympathetic dystrophy. H-wave stimulation has also been used to accelerate healing of wounds such as diabetic ulcers and to improve range of motion and function after orthopedic surgery. H-wave electrical stimulation must be distinguished from the H-waves that are a component of electromyography.

Rationale

Summary

Two small controlled trials are insufficient to permit conclusions about the effectiveness of H-wave electrical stimulation as a pain treatment. Additional sham-controlled studies are needed from other investigators, preferably studies that are clearly blinded, specify the handling of any withdrawals, and provide long-term comparative follow-up data. One small randomized controlled trial (RCT) represents insufficient evidence on the effectiveness of H-wave stimulation for improving strength and function after rotator cuff surgery. No comparative studies have been published evaluating H-wave stimulation to accelerate wound healing. In addition, no studies were identified that evaluated H-wave stimulation for any clinical application other than those described above.

Recent literature suggests that H-wave electrical stimulation may provide clinically meaningful pain reduction and could serve as an adjunct within non-opioid, multimodal pain management strategies (Williamson et al.). This consideration is particularly relevant in the context of the ongoing opioid crisis. However, current evidence also emphasizes the need for higher-quality research and rigorous long-term clinical trials to validate appropriate use and define specific indications for most forms of electrical stimulation (Williamson et al.; Allen et al.). The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.
