CPT® Code 25135

The procedure described by CPT® Code 25135 involves the excision or curettage of a bone cyst or a benign tumor located within the carpal bones, which are the eight small bones that form the wrist joint. This surgical intervention is performed to remove non-cancerous growths that may cause discomfort, limit mobility, or lead to other complications. The term 'excision' refers to the surgical removal of tissue, while 'curettage' involves scraping away the abnormal tissue. In this specific procedure, the physician not only removes the cyst or tumor but also repairs the resulting wound using an autograft, which is a bone graft taken from the patient's own body. This approach is essential for promoting healing and restoring the structural integrity of the wrist. It is important to note that if a graft from a donor patient is used instead, CPT® Code 25136 should be applied. The use of an autograft is significant as it typically leads to better integration and healing compared to grafts from other sources.
