Wound Debridement Before the Vacuum: What Medicare Data Shows About Where NPWT Actually Sits in Care (2026)
Medicare professional-service data and current wound guidance show why debridement and dressings define the pathway—and why NPWT remains a selective downstream adjunct.

Buyer Guide
Single-Use vs Reusable NPWT Pump: A Disposable-vs-Powered Procurement Decision Matrix Built on FDA Product Codes, HCPCS Reimbursement and Per-Episode Cost
The FDA itself splits NPWT into reusable powered, non-powered mechanical and disposable powered single-use pumps under three different Class II product codes, and the right buy flows from exudate volume, wound complexity, care setting and reimbursement path rather than a blanket claim that disposable is better.

Negative Pressure Wound Therapy Dressing Selection: What the PVA-versus-PU Foam, Pore-Size and Closed-Incision-versus-Open-Wound Evidence Actually Supports
Navigating NPWT dressing selection requires separating material mechanics from clinical healing claims—evaluating open-pore PU black foam (400–600 µm) for high-exudate granulation against hydro-retentive PVA white foam for sensitive wound beds, respecting the 48–72 hour open-wound change boundary, and understanding the FDA regulatory divide between open-wound (OMP) and closed-incision (QFC) devices.

How to Specify a Negative Pressure Wound Therapy (NPWT) System: A Lot-by-Lot Tender, RFQ & Acceptance Checklist for Pumps, Dressings and Canisters (2026)
A hospital procurement, health-system category management, or distributor team specifying negative pressure wound therapy (NPWT) should not issue a single bundled RFQ. Structure tenders into platform lots (acute heavy-duty, portable ambulatory, single-use/disposable, consumables, rental), map every pump performance and alarm requirement directly to documented FDA failure modes (leak, occlusion, canister overflow, power thermal cutoff), and demand a 6-part regulatory evidence pack (510(k), UDI, ISO 10993, IEC 60601-1, EO sterilization) before awarding volume.
