CPT® Code 27640

The CPT® Code 27640 refers to a surgical procedure known as partial excision of bone, specifically targeting the tibia. This procedure is performed to address conditions such as osteomyelitis, which is an infection of the bone. The common language description elaborates on the techniques involved, including craterization and saucerization, which are methods used to remove infected and necrotic bone tissue. These techniques create a shallow depression in the bone surface, facilitating drainage from the infected area. Additionally, diaphysectomy is a technique that involves the removal of the infected portion of the shaft of a long bone, in this case, the tibia. The procedure begins with an incision through the skin and soft tissue over the site of infection, allowing access to the affected area. The surgical approach includes resecting any soft tissue sinus tracts and devitalized soft tissue, exposing the necrotic and infected bone. The extent of bone removal is determined by the severity of the infection, and the procedure aims to eliminate all devitalized and infected tissue to promote healing and recovery. Proper irrigation of the wound with sterile saline or an antibiotic solution is performed before the surgical site is closed, often with a drain placed to manage any potential fluid accumulation.
