Benefit Application
Benefit determinations are based on the applicable contract language in effect at the time the
services were rendered. Exclusions, limitations or exceptions may apply. Benefits may vary
based on contract, and individual member benefits must be verified. Wellmark determines medical
necessity only if the benefit exists and no contract exclusions are applicable. This medical
policy may not apply to FEP. Benefits are determined by the Federal Employee Program.
This Medical Policy document describes the status of medical technology at the time the document
was developed. Since that time, new technology may have emerged or new medical literature may
have been published. This Medical Policy will be reviewed regularly and be updated as scientific
and medical literature becomes available.
Description:
Uterine fibroids (leiomyomata) are one of the most common conditions affecting women in the reproductive years; symptoms include menorrhagia, pelvic pressure, or pain. Hysterectomy and various myomectomy procedures are considered the gold standard treatment. However, there has been longstanding research interest in developing minimally invasive alternatives including endometrial ablation, various laparoscopic ablative procedures using differing energy sources (i.e., laser, radiofrequency ablation or cryotherapy), and uterine artery embolization.
Recently, there has been interest in using high-intensity focused ultrasound treatment that is guided by magnetic resonance imaging (MRI) as a totally noninvasive approach to the ablation of uterine fibroids. The ultrasound beam penetrates through the soft tissues and, using MRI for guidance and monitoring, the beam can be focused on targeted sites. The ultrasound causes a local increase in temperature in the target tissue, resulting in coagulation necrosis while sparing the surrounding normal structures. The ultrasound waves from each sonication can be focused into a maximum tissue volume of 4.3 cubic centimeters, causing a rapid rise in temperature sufficient to cause tissue ablation at the focal point. Initial protocols allowed treatment of only up to 33% volume of each fibroid, although this has subsequently been expanded to permit treatment of up to 50% volume of each fibroid. In addition to providing guidance, the associated MRI imaging can provide on-line thermometric imaging that provides a temperature “map” that can further confirm the therapeutic effect of the ablation treatment and allow for real time adjustment of the treatment parameters. The ultrasound equipment is all specially designed to be compatible with MRI magnets.
MRI-guided high-intensity focused ultrasound ablation as a treatment of benign prostatic hypertrophy (BPH) and of tumors of the breast, prostate, and brain is also being studied, as well as use in the palliative treatment of painful bone metastases. However, the only FDA approved device for MRI-guided ultrasound ablation is for the treatment of uterine fibroids.
Research has also been conducted involving the use of B-mode ultrasound and computerized tomography as the image guidance mechanisms to target tissues for ablation.

Policy:
Image guided high-intensity ultrasound ablation of uterine fibroids is considered investigational.
Image guided high-intensity ultrasound ablation is considered investigational for the treatment of benign and malignant tumors including, but not limited to, tumors of the breast, brain, and prostate; benign prostatic hypertrophy; and palliative treatment of bone metastases.
To date, there are no randomized controlled trials and only one non-randomized study comparing MRI-guided high intensity ultrasound to a different treatment. Other than lack of randomization, this study was limited in that data on the comparison group was not published until 5 years after data on the treatment group, the clinical significance of the primary outcome was unclear, and there were no follow-up data beyond 1 year. There is insufficient evidence on the long-term treatment effects, recurrence rates, and impact on future fertility and pregnancy.
MRI-guided high intensity ultrasound is being investigated for use in several applications that are not currently approved by the FDA. There are some preliminary reports of safety and efficacy in small numbers of patients. Due to a lack of regulatory approval and insufficient evidence of the impact on health outcomes, MRI-guided high intensity ultrasound is considered investigational for treatment of other benign and malignant tumors.

Wellmark medical policies address the complex issue
of technology assessment of new and emerging treatments, devices,
drugs, etc. They are developed to
assist in administering plan benefits and constitute neither offers of
coverage nor medical advice. Wellmark medical policies contain only a
partial, general description of plan or program benefits and do not
constitute a contract. Wellmark does not provide health care services
and, therefore, cannot guarantee any results or outcomes.
Participating providers are independent contractors in private
practice and are neither employees nor agents of Wellmark or its
affiliates. Treating providers are solely responsible for medical
advice and treatment of members. Our medical policies may be updated
and therefore are subject to change without notice.
