CPT® Code 27641

The CPT® Code 27641 refers to a surgical procedure known as partial excision of the fibula, specifically targeting infected or necrotic bone due to conditions such as osteomyelitis. This procedure encompasses techniques such as craterization, saucerization, and diaphysectomy. Craterization and saucerization involve the removal of infected and dead bone tissue to create a shallow depression on the bone surface, facilitating drainage from the infected area. Diaphysectomy, on the other hand, entails the excision of the infected segment of the shaft of a long bone, in this case, the fibula. The procedure begins with an incision through the skin and soft tissue over the osteomyelitis site, allowing access to the affected area. The surgical approach includes the resection of any soft tissue sinus tracts and devitalized soft tissue, followed by the exposure of the necrotic and infected bone. The extent of bone removal is determined by the severity of the infection, ensuring that all compromised tissue is adequately addressed to promote healing and prevent further complications.
