CPT® Code 97022

Whirlpool therapy, as described by CPT® Code 97022, is a specialized form of hydrotherapy that involves immersing a part of the body or the entire body in a tub filled with water that is agitated by a motor. This therapeutic modality can utilize water at varying temperatures, typically warm (ranging from 98 to 110 degrees Fahrenheit) or cold (between 50 and 60 degrees Fahrenheit). The application of warm whirlpool therapy is particularly beneficial as it enhances blood circulation by dilating blood vessels, which facilitates the delivery of oxygen and essential cells to areas of injury. This increased blood flow is instrumental in promoting healing, improving the range of motion, alleviating pain, and reducing muscle spasms. Conversely, cold whirlpool therapy serves a different purpose by constricting blood vessels, which can help in minimizing inflammation and swelling. Additionally, whirlpool therapy is effective in treating open wounds, as it aids in the debridement process by removing necrotic tissue, cellular debris, and biofilm, as well as eliminating dressing materials and other contaminants. Overall, whirlpool therapy is a versatile and valuable treatment option in rehabilitation and recovery settings.
