CPT® Code 27600

A decompression fasciotomy of the lower leg is a surgical procedure aimed at alleviating the pressure within the muscle compartments of the leg, specifically targeting the anterior and/or lateral compartments. The lower leg is anatomically divided into three distinct muscle compartments: anterior, lateral, and posterior. Each of these compartments is encased in a tough, fibrous tissue known as fascia, which does not stretch. When conditions such as long bone fractures, crush injuries, or other forms of trauma occur, swelling can develop within these compartments. This swelling leads to increased interstitial pressure, which can compromise blood flow and result in tissue necrosis, ultimately causing permanent functional impairment of the limb if not addressed promptly. The primary goal of the decompression fasciotomy is to relieve this pressure by surgically opening the fascia, thereby allowing for the expansion of the swollen muscle tissue. In the case of CPT® Code 27600, the procedure specifically involves the anterior and/or lateral compartments, where a longitudinal incision is made over the intermuscular septum to facilitate access and decompression. This intervention is critical in preventing severe complications associated with compartment syndrome, ensuring the preservation of limb function and overall patient health.
