Coverage Determinations
Coverage determination for stationary ultrasonic diathermy devices
Medicare Advantage: not covered; Commercial: not medically necessary based on insufficient evidence
Use of stationary ultrasonic diathermy devices for the treatment of musculoskeletal pain is excluded. For Medicare Advantage Plans, these devices are not covered because the evidence is insufficient to determine effects on health outcomes.
For Commercial Products, ultrasonic diathermy devices for the treatment of musculoskeletal pain are considered not medically necessary due to insufficient evidence to determine their effect on health outcomes.

Background and Clinical Context
Therapeutic ultrasound delivers acoustic energy (≥20 kHz) to tissues to generate deep heating, with the intended clinical effects of reducing pain, muscle spasm, and improving tissue extensibility. Conventional therapeutic ultrasound is typically clinic‑based and delivered in short sessions via a handheld wand with coupling gel. Stationary ultrasonic diathermy devices are portable/wearable systems that provide continuous, low‑intensity therapeutic ultrasound applied to the skin for extended periods (hours), enabling at‑home self‑treatment. Evidence on these stationary devices for musculoskeletal pain is currently insufficient to demonstrate meaningful improvements in health outcomes, which underlies the noncoverage and not medically necessary determinations.
Definitions
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
