CPT® Code 25929

The CPT® Code 25929 refers to a specific surgical procedure known as transmetacarpal amputation with secondary closure or scar revision. This procedure involves the complete removal of the bones that constitute the fingers from the hand, effectively amputating the fingers. The term 'transmetacarpal' indicates that the amputation occurs at the level of the metacarpal bones, which are the long bones in the hand that connect the wrist to the fingers. Following the initial amputation, there may be a need for further intervention at the surgical site. This is where the secondary closure or scar revision comes into play. If the physician returns to the site of the amputation to perform a more permanent closure of the wound or to revise the scar tissue that has formed, this procedure is coded as 25929. It is important to note that this code is specifically for cases where the physician is addressing the closure or appearance of the surgical site after the initial amputation has taken place. In contrast, if the physician revisits the site to remove additional tissue, a different code, 25931, would be applicable. This distinction is crucial for accurate medical coding and billing purposes.
