CPT® Code 26070

The CPT® Code 26070 refers to an arthrotomy procedure specifically targeting the carpometacarpal (CMC) joint, which is one of the five joints located in each hand. These joints serve as the connections between the distal row of carpal bones in the wrist and the proximal ends of the metacarpal bones that form the palm. During this procedure, a surgical incision is made over the affected CMC joint, allowing for direct access to the joint space. The surgeon carefully dissects the surrounding soft tissues while protecting vital structures such as nerves and blood vessels. Once the joint capsule is exposed, it is incised to facilitate a thorough visual inspection of the joint interior. If any signs of infection are present, the surgeon will drain fluid, blood, and any purulent material that may have accumulated. Additionally, any loculated fluid collections are addressed through blunt dissection. To ensure the joint is free of debris, it is flushed with a sterile saline or antibiotic solution using a technique known as pulsed lavage. If a foreign body is identified within the joint, it is meticulously located and removed. After the procedure, drains may be placed to prevent fluid accumulation, and the incision is then closed around these drains. It is important to note that similar procedures on the metacarpophalangeal (MCP) joint or interphalangeal (IP) joint are coded differently, specifically using CPT® Codes 26075 and 26080, respectively. Each of these codes is designated for reporting procedures performed on separate joints treated during the surgical intervention.
