1. What is CPT Code 25040?

CPT 25040 is a code used to describe the arthrotomy procedure performed on the radiocarpal or midcarpal joint. This procedure involves making an incision to gain access to the joint, and it may include exploration, drainage of fluid or abscess, or removal of a foreign body.

The official description of CPT code 25040 is: ‘Arthrotomy, radiocarpal or midcarpal joint, with exploration, drainage, or removal of foreign body.’

During the arthrotomy procedure, the healthcare provider begins by preparing and anesthetizing the patient. They then make an incision over the wrist or midpalm area, carefully dissecting through the subcutaneous tissue until reaching the joint capsule. The provider opens the joint capsule to gain direct access to the joint space. They thoroughly explore the joint to identify any abnormalities or foreign bodies. If necessary, they may remove a foreign body, such as a bullet or nail, or drain any fluid or abscess present. The wound is then irrigated with an antibiotic solution, and the provider sutures the wound in layers. In some cases, a drain may be placed.
