Medicare Advantage Policy

Title:Bioimpedance for the Detection of Lymphedema
Policy #:MA07.052

This policy is applicable to the Company’s Medicare Advantage products only. Policies that are applicable to the Company’s commercial products are accessible via a separate commercial policy database.


The Company makes decisions on coverage based on the Centers for Medicare and Medicaid Services (CMS) regulations and guidance, benefit plan documents and contracts, and the member’s medical history and condition. If CMS does not have a position addressing a service, the Company makes decisions based on Company Policy Bulletins. Benefits may vary based on contract, and individual member benefits must be verified. The Company determines medical necessity only if the benefit exists and no contract exclusions are applicable. Although the Medicare Advantage Policy Bulletin is consistent with Medicare’s regulations and guidance, the Company’s payment methodology may differ from Medicare.

When services can be administered in various settings, the Company reserves the right to reimburse only those services that are furnished in the most appropriate and cost-effective setting that is appropriate to the member’s medical needs and condition. This decision is based on the member’s current medical condition and any required monitoring or additional services that may coincide with the delivery of this service.


This Policy Bulletin document describes the status of CMS coverage, medical terminology, and/or benefit plan documents and contracts at the time the document was developed. This Policy Bulletin will be reviewed regularly and be updated as Medicare changes their regulations and guidance, scientific and medical literature becomes available, and/or the benefit plan documents and/or contracts are changed.



Policy

Coverage is subject to the terms, conditions, and limitations of the member's Evidence of Coverage.

Although the US Food and Drug Administration (FDA) has approved devices for bioimpedance for the detection of lymphedema, the Company has determined that the effectiveness of this procedure cannot be established by review of the available published peer-reviewed literature. Therefore, bioimpedance for the detection of lymphedema is considered experimental/investigational by the Company and not covered.
Policy Guidelines

There is no Medicare coverage determination addressing this service; therefore, the Company policy is applicable.

BENEFIT APPLICATION

Subject to the terms and conditions of the applicable Evidence of Coverage, bioimpedance for the detection of lymphedema is not eligible for payment under the medical benefits of the Company's Medicare Advantage products because the service is considered experimental/investigational and, therefore, not covered.

Services that are experimental/investigational are excluded for the Company's Medicare Advantage products. Therefore, they are not eligible for reimbursement consideration.

US FOOD AND DRUG ADMINISTRATION (FDA)

There are numerous devices approved by the FDA for bioimpedance for the detection of lymphedema.

Description

Lymphedema is a condition characterized by excess edema and protein in the tissues caused by fluid that is not drained by the lymphatic system. The lymphatic system is part of the body's circulatory system, and its main function is to drain fluid, absorb fats, maintain the body's fluid balance, and help defend the body against disease. The failure of this system can lead to lymphedema and other conditions.

There are two types of lymphedema: primary and secondary. Primary lymphedema is an inherited condition and is determined by genetic factors. Secondary lymphedema is usually caused by trauma, radiation therapy, surgery, or infection that causes a disruption in the lymphatic channels or loss of lymph nodes.

In time, lymphedema can lead to recurring infections, pain, and decreased or loss of function and mobility. Control of the condition usually involves exercise, compression bandaging, and massage. The practice of measuring limb girth with tape measures or the immersion of the limb in water to measure the displacement of the water is considered the gold standard for detection of lymphedema. One of the many problems associated with lymphedema involves early detection; however, detection in the early subclinical phase is difficult. While there is no cure for lymphedema, early detection and treatment are critical in achieving the optimal outcome for the individual.

There are five grades of lymphedema, using the Miller Classification:
  • Grade 0 (subclinical): Individual has abnormal or non-efficient lymph rerouting but does not have clinical edema.
  • Grade 1: Normal in appearance, positive for pitting edema, edema resolves or greatly decreases with elevation of the limb.
  • Grade 2: Skin on affected limb develops yellowish discoloration, there is skin thickening, positive for pitting under moderate pressure, moderate decrease in edema with elevation, loss of limb mobility and function as edema increases, physical therapy is necessary.
  • Grade 3: Development of vesicles and papules on the affected limb, keratosis of the effective limb, skin thickening with little pitting on pressure, minimal decrease of edema with elevation, decreased function and mobility of affected limb, physical therapy and medical intervention are necessary.
  • Grade 4: Increased yellowish discoloration, increased pigmentation, weeping vesicles, increased keratotic papules, increased skin thickening, no pitting with pressure, no decrease in edema with elevation, marked loss of limb function and mobility, multimodality therapy is required.

The detection of lymphedema at a subclinical level is a current area of study. The detection of grade 0 lymphedema is problematic and may be present for months or years without physical manifestation. Optimally, the "at risk" limb is tested pre- and post-surgery (eg, mastectomy or lumpectomy with lymph node dissection) using bioimpedance spectroscopy. Bioimpedance spectroscopy (ie, impedance plethysmography) is a measure of the resistance met by a current passed through the skin via electrodes. The difference appreciated between the readings pre- and post-surgery is proposed to determine the presence or lack of lymphedema.

Currently, there is little information regarding the technical and diagnostic performance of bioimpedance testing for the detection of lymphedema. Also, there are no comparative clinical trials that demonstrate the impact of bioimpedance on clinical outcomes. The approach to subclinical lymphedema (diagnosis and treatment) appears to be under active investigation.
