CPT® Code 25101

The procedure described by CPT® Code 25101 refers to an arthrotomy of the wrist joint, which involves making an incision to access the joint for exploration. This procedure can include various actions such as joint exploration, obtaining biopsies, and the removal of loose or foreign bodies within the joint space. The incision can be either a longitudinal midline incision or a horizontal incision, depending on the specific location of the pathology being addressed. The surgical approach requires careful dissection through the skin and underlying tissues, including the development of full-thickness skin flaps down to the extensor retinaculum, while taking precautions to protect important anatomical structures such as the superficial radial nerve and the dorsal sensory branch of the ulnar nerve, as well as associated blood vessels. The retinaculum is then incised to allow access to the wrist joint, facilitating further exploration and intervention as necessary. This procedure is critical for diagnosing and treating various wrist joint conditions, particularly when less invasive methods have not provided sufficient information or relief.
