Background Information
This technology was reviewed by the State Health Technology Clinical Committee (HTCC) in November 2016 and the determination was finalized on January 20, 2017.  The committee’s determination, based on a systematic review of the evidence of safety, efficacy and cost-effectiveness, is that NPWT is a covered benefit with conditions.  Complete information on this HTCC determination is available at: http://www.hca.wa.gov/about-hca/health-technology-assessment/health-technology-reviews.

In adopting this HTCC coverage determination, the Department has concluded that the determination does not conflict with any state statute. Any coverage for investigational treatment would be considered per WAC 296-20-02850.  Any coverage for health technologies that have a FDA Humanitarian Device Exemption status would be considered per RCW 70.14.120 (1) (b).   

Implementation of the Coverage Decision
All requests for NPWT require prior authorization.  The service may be covered only for care of a condition accepted on or related to the claim.
