POLICY UPDATE CHANGES

Removed language indicating electromagnetic therapy for wounds is medically necessary in certain circumstances.

Added language to indicate electromagnetic therapy is unproven and not medically necessary due to insufficient evidence of efficacy for treating wounds or ulcers including but not limited to arterial ulcers, chronic pressure ulcers, diabetic foot ulcers, soft tissue injuries, and venous stasis ulcers.

Revised language pertaining to medical necessity clinical coverage criteria; removed reference to InterQual ® Medicare: Procedures, Electrical Stimulation (ES) and Electromagnetic Therapy for the Treatment of Wounds NCD.

Coverage Criteria — Electromagnetic Therapy for Wounds

Not medically necessary — general

Covered when ALL of the following are met

Primary stance: Electromagnetic therapy for wounds is considered unproven and not medically necessary due to insufficient evidence of efficacy for treating wounds or ulcers (including arterial ulcers, chronic pressure ulcers, diabetic foot ulcers, soft tissue injuries, and venous stasis ulcers).

Policy declares NMN across listed wound types.

The FDA has not approved any electromagnetic devices specifically for the treatment of chronic wounds. Use of electromagnetic devices for wound healing is an off-label indication. This information is provided for informational purposes and FDA approval alone does not determine coverage.

UnitedHealthcare considers electromagnetic therapy for wounds unproven and not medically necessary due to insufficient evidence of efficacy. This stance applies to treatment of wounds and ulcers including, but not limited to, arterial ulcers, chronic pressure ulcers, diabetic foot ulcers, soft tissue injuries, and venous stasis ulcers. The policy was revised effective 04/01/2026 to remove prior language that described certain circumstances as medically necessary and to clarify that electromagnetic therapy is not covered for these indications.

Step Therapy

Step therapy — none specified

Background

Electromagnetic therapy (also referred to as pulsed electromagnetic induction/field therapy) delivers electromagnetic fields to the wound area rather than applying direct electrical current. Published studies consist of small randomized trials and systematic reviews with inconsistent results and methodological limitations, leaving the overall evidence insufficient to support the efficacy of electromagnetic therapy for chronic wounds such as venous leg ulcers, pressure ulcers, and diabetic foot ulcers.

Definitions

Electromagnetic therapy (EMT) definition

TermElectromagnetic therapy (EMT)

DefinitionApplication of electromagnetic fields to the wound area; also referred to as pulsed electromagnetic induction, pulsed electromagnetic field, and pulsed electromagnetic therapy.

Also calledPulsed electromagnetic induction; pulsed electromagnetic field; pulsed electromagnetic therapy

Mechanism — distinctionApplies electromagnetic fields to the wound rather than direct application of electrical current.
