Wisconsin Physician Services (WPS) covering Iowa, Kansas, Missouri and Nebraska is publishing an LCD to make the Wound VAC "non-covered modality" claiming a lack of evidence.

I am deeply troubled. I have personally witnessed many limbs and lives saved with Wound VAC therapy. How can they possibly ignore all the good RCT studies done by Dr. Armstrong and many others???


Non-Covered Modalities:

Negative Pressure Wound Therapy (97605-97606): involves the application of controlled or intermittent negative pressure to a properly dressed wound cavity. Suction (negative pressure) is applied under airtight wound dressings to promote the healing of open wounds resistant to prior treatments. Negative pressure wound therapy facilitates the removal of excessive exudates that inhibit wound healing. Medicare coverage will no longer be considered for negative pressure wound therapy when it is used as an adjunct to surgery, an alternative to surgery, or a therapy for refractory chronic wounds.


CMS partnered with Agency of Healthcare Research and Quality (AHRQ) to commission a review of NPWT devices to ensure all relevant studies and information on NPWT were captured.  ECRI Institute solicited information from stakeholders and searched literature in conducting this review. A draft report of their findings was published for comment in April 2009. After analysis of comments received, ECRI concluded that the available evidence does not support significant therapeutic distinction of a NPWT system or component of a system. The report informed CMS' HCPCS workgroup's decision. The final report will be publicly available no later than June 10, 2009 on AHRQ's homepage for the Technology Assessment Program at http://www.ahrq.gov/clinic/techix.htm.

Ultrasonic Wound Debridement: (CPT code 0183T) is a system that uses continuous low   frequency ultrasonic energy to atomize a liquid and deliver continuous low frequency ultrasound to the wound bed. This cleansing method is not considered a significantly separately payable coverable service by Medicare. Therefore Mist Therapy (CPT code 0813T) is included in the payment for the E&M or wound care services. Mist Therapy™ System 5.0 Wound Treatment Device is not covered.

  • Hurray !  Don't you love when the good guys win ?


    Thanks for the great news gathering and reporting here, guys...

  • It wasn't a rumor. It was very real problem in Mid-West. The bottom line, their reasoning for making NPWT non-covered service wasn't sound, and they quickly reversed their position.

    Here's the official response from WPS below.


    WPS Rescinds Non Coverage Policy for NPWT:

    we have concluded that we were premature in our assessment of this technology. As result the LCD will be changed back to the original description of NPWT   as in the current policy which is being retired at the end of this month. Since the effective date for the new policy is 9-1-2009 this will not cause any inappropriate denial in claims.  I will contact the appropriate people to ensure that this information is placed on the WPS ListServ and is published in the next Communiqué.

    The LCD L28572 Wound Care (GSURG-051) will now read as the same language as before which is in the current policy.

    We apologize for the inconsistancy.

  • I just heard that this was apparently a rumor that got distributed and it got out of hand, as of right now, no coverage regarding the VAC has been changed in texas from what I can see, The use of this medical device is vital in some of the major Diabetic Ulcers and especially some of the Gunshut wounds that I have seen presented here..

  • Thanks, Lee. That's great news.

    What's curious is how WPS misinterpreted the original report, stating that they could not compare one NWPT against the others, since the KCI device is the only one with the RCT data. 

    I do encourage the other NWPT device companies to fund more clinical studies (not just case studies) to prove their points. In other words, I or any other conscientious clinicians won't use non-KCI NPWT device until they do so.  


  • Thanks, Lee. This is excellent news, not as much for us as it is for the patients who so often have no place else to turn in order to build those masses of sturdy, viable granulation tissue that are the framework for the reconstuction of the foot.

    This is definitely great news and I know a lot of patients and physicians welcoming this news.

  • I just found out that WPS has reversed their decision and will be covering NPWT as per their previous guidelines.

  • I hope that is the case! I also contacted KCI about this here in Texas and they are checking with the reimbursement people but I have not yet heard back.  

    I could not imagine that this would be the case. As you know, while the "VAC wanna be's" have not gone through the same rigorous evidence-based  trials they have been trying to suggest their product has been through those same trials. I thought that perhaps that was the source of the problem.   I will post anything else I here from here, Kazu. Thanks for the update.

  • The update of the WPS (Mid-West Medicare) debacle with "NPWT becoming non-covered service."

    KCI officially says it was a case of misinterpretation and they are confident to reverse their decision (which is not finalized yet).

    Again, sorry for the excitement. I am taking a big sigh of relief.

  • I've read the report in depth, and this is what I found out.


    (1). The original ECRI report was to investigate the clinical evidence of various NPWT devices as compared to each other (see under the Methods of the Review).

    (2). No studies directly comparing one NPWT system to another NPWT system were identified that addressed the "Key Questions" (In fact, there was no RCT available for non-KCI device, so no comparison could be made.)

    Quote: “After analysis of comments received, ECRI concluded that the available evidence does not support significant therapeutic distinction of a NPWT system or component of a system.”

    (3). WPS (Wisconsin Physicians Services) appears to misinterpret the report above, saying that available evidence does not support the use of NPWT and therapeutic distinction compared to the conventional wound care treatment. (... therefore, it should be a non-covered service)

    I was told that the Alliance of Wound Care is aware and taking up the issue.

    It seem to me that it may be a matter of miscommunication, as opposed to a malicious attempt by the "powers-that-be" to take away Wound VAC from us. 

    Will keep you posted...
