Coverage Summary

Scope: This policy addresses coverage and medical necessity for ultrasonic diathermy devices (including low-intensity continuous therapeutic ultrasound / sustained acoustic medicine) used for treatment of musculoskeletal pain in Medicare Advantage and commercial plans.

Coverage stance: Not covered / not_covered_cosmetic for Medicare Advantage and Not medically necessary for Commercial Products due to insufficient evidence to determine effects on health outcomes. Confidence in this brief: 0.88.

Medical-Necessity / Coverage Determination

Coverage Determination

Coverage stance for ultrasonic diathermy devices for musculoskeletal pain:

ALL of the following

Medicare Advantage Plans: Ultrasonic diathermy devices for the treatment of musculoskeletal pain are considered not covered because evidence is insufficient to determine the effects of the technology on health outcomes.
Commercial Products: Ultrasonic diathermy devices for the treatment of musculoskeletal pain are considered not medically necessary because evidence is insufficient to determine the effects of the technology on health outcomes.

ref”:

Evidence summary: A meta-analysis and randomized controlled trials (including small RCTs of sustained acoustic medicine devices) reported some reductions in pain and improvements in quality of life in certain short-duration, small studies, but study limitations (heterogeneity of treatment areas and outcomes, small sample sizes, and short follow-up) result in overall insufficient evidence to establish a clear net health benefit.

Not Covered / Not Medically Necessary

Policy stance: For Medicare Advantage Plans, ultrasonic diathermy devices for musculoskeletal pain are not covered because the evidence is insufficient to determine effects on health outcomes. For Commercial Products, these devices are considered not medically necessary for the same reason. The policy frames this coverage stance as not covered / cosmetic for Medicare Advantage and not medically necessary for commercial coverage, and lists related HCPCS codes as not covered or not medically necessary.

Not Covered

Not covered / Not medically necessary determinations:

Not Covered / Not Medically Necessary: For Medicare Advantage Plans: not covered; For Commercial Products: not medically necessary — evidence is insufficient to determine effects on health outcomes.

Related HCPCS codes: K1004, K1036 are not covered for Medicare Advantage and not medically necessary for Commercial Products.

Background and Evidence

Background: Therapeutic ultrasound (ultrasonic diathermy) uses acoustic vibrations (≥20 kHz) to generate deep heat in collagen-rich tissues to treat musculoskeletal conditions such as pain, muscle spasms, and joint contractures. Traditionally delivered in-clinic with short sessions, newer stationary/portable devices enable self-applied, continuous low-intensity therapeutic ultrasound at home for multihour treatments—often referred to as sustained acoustic medicine (SAM).

Device status and evidence limitations: Several stationary/home ultrasonic diathermy devices (including Manasport, sam®, PainShield MD, and others) have received FDA 510(k) clearance for delivering ultrasound to generate deep heat for symptom relief. Available clinical data include a meta-analysis and a few RCTs showing some pain improvements in small, short-duration trials, but limitations such as heterogeneity in treatment areas and implementations, small sample sizes, and short follow-up periods make the evidence insufficient to determine an improvement in net health outcomes.

Evidence and definitions

EvidenceIncluded studies demonstrated pain reduction and improved quality of life in some small trials, but limitations (heterogeneity, sample sizes, short follow-up) make evidence insufficient to establish net health benefit.

Definition - Ultrasonic diathermyApplication of ultrasonic energy (>20 kHz) to generate deep heat within body tissues for treatment of musculoskeletal conditions.

Definition - Sustained Acoustic Medicine (SAM)A type of low-intensity continuous therapeutic ultrasound delivered by portable/wearable stationary devices for prolonged home use.

Definitions

Definitions: Ultrasonic diathermy — application of ultrasonic energy (>20 kHz) to generate deep heat within body tissues for treatment of musculoskeletal conditions.

Sustained Acoustic Medicine (SAM) — a form of low-intensity continuous therapeutic ultrasound delivered by portable or wearable stationary devices for prolonged (multihour) home use; devices of this type have been marketed and some have received FDA 510(k) clearance.
