V.A.C. Therapy

While V.A.C.® Therapy may initially seem more expensive, the clinical benefits may actually help facilities lower their overall cost of care. You can learn more about V.A.C. Therapy’s demonstrated cost effectiveness.

Can you treat more than one wound with one therapy unit?

Yes. KCI has established two methods for connecting wounds to one therapy unit: “Bridging” and “Y-connecting.”

Bridging can be accomplished when you have multiple wounds of similar pathology in close proximity to one another. The V.A.C.® drape is placed on the intact skin between wounds, and a strip of foam is placed from one wound bed to the other over the draped skin. As long as all pieces of foam are touching each other, you can place the tubing in a central location and use one pump to distribute pressure throughout all the wounds.

Y-connecting allows you to treat multiple, non-infected wounds that are a larger distance apart by using a connector that can support two separate tubing connections. Negative pressure in either situation is distributed across the wounds, yet controlled by one pump.

Please reference the V.A.C. Therapy Clinical Guidelines for more information.

Can a hospital bill for V.A.C. Therapy?

Yes, a hospital can include charges for the daily therapy unit rental and dressings and canisters on its bill. The charge is established in the hospital charge description master with an association to the following UB 92 revenue codes:

  • Daily Unit Rental – UB92 code 947 (medical surgical supplies)
  • Dressings and canisters – UB92 code 272 (sterile medical surgical supplies)

Gauze or foam dressings. Is there a difference?

Yes, there is a clinical difference. Although the V.A.C.® GranuFoam™ Dressing (black foam) may seem like simple surgical foam, it has been specifically engineered to deliver NPWT. The hydrophobic, open pore structure of V.A.C. GranuFoam Dressings adapt to the contours of deep or irregularly shaped wounds in order to provide equal distribution of pressure at the wound site. These open pores are also manufactured under specifications to achieve a 400-600 micron pore size to help promote wound healing.

For these reasons, gauze will not provide the proven benefits of NPWT, and, in some cases, the pooling of fluids may occur and interfere with the wound healing process11, 14.
