CPT® Code 26034

The procedure described by CPT® Code 26034 involves an incision into the bone cortex of the hand or finger, specifically targeting conditions such as osteomyelitis or a bone abscess. Osteomyelitis refers to an infection of the bone, while a bone abscess is a localized collection of pus within the bone. The bones involved in this procedure include the metacarpals of the hand and the proximal, middle, and distal phalanges of the fingers. During the procedure, an incision is made through the skin and soft tissue to access the infected area of the bone. The periosteum, which is the dense layer of vascular connective tissue enveloping the bones, is elevated to expose the underlying bone cortex. A small section, or button, of the cortical bone is then removed to access the bone marrow, which is crucial for alleviating pressure caused by inflammation and preventing further restriction of blood flow to the infected area. If pus is present, the initial incision may be enlarged using specialized instruments such as a chisel or gouge, allowing for effective drainage of the abscess. In cases where the epiphysis, the end part of a long bone, is affected, a portion of the epiphyseal cortex may also be excised to ensure complete drainage and treatment of the infection.
