CPT® Code 28122

Partial excision (craterization, saucerization, sequestrectomy, or diaphysectomy) bone (eg, osteomyelitis or bossing); tarsal or metatarsal bone, except talus or calcaneus

The procedure described by CPT® Code 28122 involves a partial excision of bone, which can also be referred to by various terms such as craterization, saucerization, sequestrectomy, or diaphysectomy. This surgical intervention is specifically performed on tarsal or metatarsal bones, excluding the talus or calcaneus. The primary indications for this procedure include conditions such as osteomyelitis, which is a serious infection of the bone characterized by the presence of pus, and bossing, which refers to a bony protrusion that may require surgical intervention. The goal of the procedure is to remove infected or necrotic bone tissue to alleviate symptoms and promote healing. Craterization and saucerization techniques are utilized to create a shallow depression in the bone surface, facilitating drainage from the infected area. Sequestrectomy focuses on excising necrotic bone that has detached from healthy bone, while diaphysectomy involves the removal of infected sections of the long bone shaft. This procedure is critical in managing infections and abnormalities in the bone structure, ensuring that the affected area is treated effectively to restore function and prevent further complications.
