CPT® Code 99185

Hypothermia, in the context of CPT® Code 99185, refers to a medically induced state where the temperature of a specific region of the body is lowered intentionally by a physician. This procedure is typically performed to reduce the metabolic rate of the tissues in that area, which can be crucial in situations where blood flow has been compromised, such as in cases of limb ischemia. By lowering the temperature, the physician aims to protect the affected tissues from damage due to lack of oxygen and nutrients, thereby potentially saving the limb from necrosis or other complications. The procedure is carefully controlled and monitored to ensure the safety and effectiveness of the treatment, making it a critical intervention in emergency and surgical settings.
