Since relatively new negative pressure wound therapy (NPWT) has become an integral part of simple to complex wound management, effective price transparency of NPWT should include the release of clear, accurate, and actionable information for patients to determine their cost of treatment and remove the guesswork. The amount and type of material used, number of hours of negative pressure application, cost of maintaining negative pressure for a definite period, etc., usually determine the cost of NPWT. With this idea of price transparency, the author attempted to classify NPWT in different ways. The author believes that, with similar attempts by various authors in the future, a better classification would evolve.
