CPT® Code 27626

The procedure described by CPT® Code 27626 refers to an arthrotomy with synovectomy of the ankle, which includes the additional step of tenosynovectomy. The synovial tissue is a specialized membrane that lines the ankle joint and is responsible for producing synovial fluid, which lubricates the joint. In certain conditions, such as rheumatoid arthritis or synovial proliferative disorders, this tissue can become inflamed, leading to an overproduction of synovial fluid and resulting in joint effusion, which is the accumulation of fluid in the joint space. The surgical approach to the ankle joint is determined by the location of the affected synovial tissue. During the procedure, a surgical incision is made through the skin and down through the soft tissues, with careful attention to preserving nearby nerves and blood vessels. The ankle joint capsule is then incised to allow for direct inspection of the joint for any signs of injury, disease, or infection. In the context of CPT® Code 27625, a motorized shaver is utilized to excise the inflamed synovium, ensuring that all diseased tissue is removed while protecting the underlying vascular and nervous structures. The joint is subsequently flushed with saline to clear any debris. After the synovectomy, as specified in CPT® Code 27626, the procedure may also involve the excision of damaged or diseased extensor tendons, which can include the tibialis anterior tendon and the retromalleolar tendons associated with the tibia and fibula. The surgical site is then closed in layers, starting with the joint capsule, followed by the soft tissues and skin, ensuring proper healing and recovery.
