Pneumatic Compression Therapy FAQ

Pneumatic compression therapy uses an inflatable garment connected to an electric pump. The pump fills and releases chambers in a controlled sequence to apply intermittent pressure to an affected limb or body area.

It may be prescribed as part of a broader lymphedema or venous-disorder treatment plan. It is generally used as an adjunct to clinician-directed care rather than as a stand-alone cure.

A clinician may consider pneumatic compression for people with diagnosed primary or secondary lymphedema, chronic edema, or certain venous disorders when it is medically appropriate.

Eligibility depends on the diagnosis, symptoms, objective findings, previous treatment, safety considerations, insurance requirements, and the patient’s or caregiver’s ability to use the equipment correctly.

For appropriately selected patients, pneumatic compression may help manage swelling, reduce limb heaviness, and support movement of lymphatic or venous fluid. Sequential pneumatic compression is commonly considered an additional treatment used alongside compression garments, exercise, skin care, elevation, and other clinician-recommended measures.

Results vary, and the device pressure, treatment area, frequency, and duration should follow the prescribing clinician’s instructions and the specific device user guide.

Medicare may cover a pneumatic compression device in the home when the applicable coverage criteria and documentation requirements are met.

For lymphedema, Medicare’s national coverage policy generally requires a four-week trial of conservative therapy that includes an appropriate compression bandage system or garment, exercise, and elevation. The treating practitioner must determine that significant symptoms remain or that there has not been significant improvement.

Coverage is not automatic. The prescribed equipment, medical record, supplier requirements, and current Medicare rules must all be reviewed.

Under Medicare’s national policy, home pneumatic compression for chronic venous insufficiency of the lower extremities is limited to patients with one or more venous stasis ulcers that have failed to heal after a six-month trial of physician-directed conservative therapy.

That conservative treatment generally includes compression, appropriate wound dressings, exercise, and elevation. Other insurers may use different medical-necessity criteria.

Payment may come from Medicare, Medicaid, a commercial health plan, a supplemental plan, or the patient, depending on eligibility and the terms of the plan.

Deductibles, coinsurance, network requirements, prior authorization, documentation rules, and covered device codes can vary. Advanced Rehab Technologies can help review benefits, but final coverage and payment decisions are made by the insurer.

Contraindications and precautions vary by device and treatment area. A pneumatic compression device should not be started without appropriate clinical evaluation.

Examples listed in some device instructions include acute pulmonary edema or decompensated heart failure, acute venous disease such as acute deep-vein thrombosis or pulmonary embolism, severe peripheral arterial disease or critical limb ischemia, an active skin or limb infection such as acute cellulitis, and any condition in which increased venous or lymphatic return is undesirable.

This is not a complete list. The prescribing clinician and the instructions for the exact device must be followed.

Equipment selection should be based on a clinical assessment and the prescription. Important factors may include the diagnosis, affected body area, severity and distribution of swelling, limb measurements, skin condition, previous treatment response, mobility, dexterity, caregiver support, and the ability to apply and operate the system safely.

Medicare applies additional criteria to certain advanced, segmented devices. A more complex device is not automatically appropriate for every patient.

Documentation may need to include the diagnosis and prognosis, symptoms, objective findings and measurements, the reason the equipment is required, conservative treatments that were tried, the patient’s response, and the ability of the patient or caregiver to use the device at home.

The exact requirements depend on the payer, prescribed device, diagnosis, and current coverage policy.

There is no single treatment schedule that is appropriate for every person or every device. Pressure, session length, frequency, garment configuration, and treatment sequence should be prescribed or approved by the treating clinician and must follow the manufacturer’s instructions.

Contact the prescribing clinician before changing pressure or treatment duration.

Stop the treatment and contact the prescribing clinician if the device causes unexpected pain, numbness, skin changes, increased swelling, breathing difficulty, dizziness, or other concerning symptoms.

Seek urgent medical care for chest pain, severe shortness of breath, symptoms of a possible blood clot, or another medical emergency.
