Negative Pressure Wound Pump

Negative Pressure Wound Therapy (NPWT) can be an effective treatment for wounds like venous stasis ulcers, diabetic wounds, surgical wounds, pressure ulcers, and more. Rice Home Medical carries two pumps for NPWT: Invia Liberty and Invia Motion.

Invia Liberty 

Invia Liberty Negative Pressure Wound Therapy system provides convenience and flexibility. It is lightweight and compact to promote patient mobility. The pump features double lumen tubing with built-in protection filters and tube clamps, and comes with a one-touch canister release button. This system also has a range of pressure settings and therapy modes and operates quietly and discreetly. Disposable canisters come in two sizes: 300 mL and 800 mL.

Invia Motion

This easy-to-use Negative Pressure Wound Therapy pump is best suited for use in the home or other post-acute settings as it helps patients comfortably go about daily activities while promoting freedom and mobility during the entire length of treatment. It has only 4 buttons and visual and audible monitoring. The canister has a capacity of 150 mL and therapy can be delivered in constant or intermittent mode. Duration of therapy is customizable and should be discussed with your care provider.

 


Insurance

Insurance coverage should always be verified with one of Rice Home Medical’s customer service representatives. Eligibility can vary by policy plan.

Medicare, and other insurance providers who follow Medicare guidelines, will cover a NPWT pump and supplies when either criterion A or B is met. A written order prior to delivery is also required.

A. Ulcers and wounds in the Home Setting:
The patient has a chronic Stage III or IV pressure ulcer, neuropathic (for example, diabetic) ulcer, venous or arterial insufficiency ulcer, or a chronic ulcer of mixed etiology present for at least 30 days. A complete wound therapy program described by criterion 1 and criteria 2, 3, or 4, as applicable depending on the type of wound, must have been tried or considered and ruled out prior to application of NPWT.

  1. For all ulcers and wounds, the following components of a wound therapy program must include a minimum or all of the following general measures, which should either be addressed, applied, or considered and ruled out prior to the application of NPWT:
    – Documentation in the patient medical record of evaluation, care, and wound measurements by a licensed medical professional (MD, DO, PA, RN, LPN, PT)
    – Application of dressings to maintain a moist wound environment
    – Debridement of necrotic tissue if present
    – Evaluation of and provision for adequate nutritional status
  2. For Stage III or IV pressure ulcers:
    – The patient has been appropriately turned and positioned
    – The patient has a used group 2 or 3 support surface for pressure ulcers on the posterior trunk or pelvis
    – The patient’s moisture and incontinence have been appropriately managed
  3. For neuropathic (for example, diabetic) ulcers:
    – The patient has been on a comprehensive diabetic management program
    – Reduction in pressure on a foot ulcer has been accomplished with appropriate modalities
  4. For venous insufficiency ulcers:
    – Compression bandages and/or garments have been consistently applied
    – Leg elevation and ambulation have been encouraged

B. Ulcers and Wounds Encountered in an Inpatient Setting:

  1. An ulcer or wound is encountered in the inpatient setting and after wound treatments under A-1 through A-4 have been tried or considered and ruled out, NPWT is initiated because it is considered in the judgement of the treating physician, the best available treatment option.
  2. The patient has complications of a surgically created wound (for example, dehiscence) or a traumatic wound (for example, pre-operative flap or graft) where there is documentation of the medical necessity for accelerated formation of granulation tissue which cannot be achieved by other available topical wound treatments.

In either situation B-1 or B-2, NPWT will be covered when treatment is ordered to continue beyond discharge to the home setting.

In order for coverage to continue, a licensed medical professional must do the following on a regular basis:

  1. Directly assess the wound(s) being treated with the NPWT pump
  2. Supervise or directly perform the NPWT dressing changes
  3. On at least a monthly basis, document changes in the ulcer’s dimensions and characteristics
