CPT® Code 26080

The CPT® Code 26080 refers to an arthrotomy procedure specifically involving the interphalangeal joint, which is the joint located between the phalanges (the bones of the fingers). This procedure encompasses exploration, drainage, or removal of loose or foreign bodies within the joint. The interphalangeal joints are crucial for finger movement and dexterity, with each hand containing nine such joints—one in the thumb and two in each finger. The procedure begins with an incision over the affected joint, allowing for direct access to the joint capsule. Once the joint is accessed, a thorough inspection is conducted to identify any pathological conditions such as infections, which may necessitate the drainage of fluid, blood, or pus. If foreign bodies are present, they are carefully located and removed to restore normal joint function. This procedure is significant in addressing joint issues that can lead to pain, swelling, and impaired mobility, thereby improving the overall function of the hand. Each arthrotomy performed on a separate interphalangeal joint is reported individually under this code, ensuring accurate documentation and billing for the services rendered.
