The CPT® Code 26125 refers to a surgical procedure known as a partial palmar fasciectomy, which involves the excision of thickened fascia in the palm and potentially the fingers. This procedure is specifically performed to address conditions such as Dupuytren's contracture, where the fascia in the palm becomes thickened and can lead to a flexion contracture of the fingers. During the surgery, a zigzag incision is typically made over the affected areas of the palm and fingers to allow for optimal access to the underlying structures. The surgeon elevates the skin and subcutaneous tissue to expose the palmar fascia and the pretendinous fascial cord. Careful dissection is performed at the metacarpal head to identify and protect the digital nerves and arteries adjacent to the tendon cords. The thickened fascia is progressively elevated from the proximal palm to the metacarpal head, and once fully freed from surrounding nerves and vessels, it is excised. This excision alleviates the flexion contracture by freeing the underlying tendon. Following the fasciectomy, the soft tissues in the palm are rearranged as necessary to cover and protect the underlying structures. The zigzag incision is then either closed directly or a skin graft may be harvested and utilized to close the surgical wound. It is important to note that this code is applicable for each additional digit from which the fascial cord is excised, and it is used in conjunction with other related codes for comprehensive billing and documentation purposes.
