CPT® Code 27630

The CPT® Code 27630 refers to the excision of a lesion located within the tendon sheath or joint capsule, specifically in the leg and/or ankle region. Common lesions that may necessitate this procedure include cysts and ganglia. Cysts are fluid-filled sacs that can develop in various tissues, while ganglia are a specific type of cyst that is multiloculated, meaning they contain multiple compartments filled with fluid, and typically arise from fibrous tissue. These lesions are generally benign, meaning they are not cancerous. However, they may cause significant discomfort or pain, particularly when the patient is standing or walking, which can lead to the decision to remove them. The surgical approach for excision is determined by the precise location of the lesion. During the procedure, a surgical incision is made in the skin, and the incision is extended through the underlying soft tissues with careful attention to preserving nearby nerves and blood vessels. Once the tendon sheath or joint capsule is adequately exposed, the surgeon identifies the cyst and meticulously dissects it away from the surrounding tendon sheath or capsule before removing it entirely. Finally, the incision is closed in layers to promote proper healing and minimize scarring.
