CPT® Code 28090

The procedure described by CPT® Code 28090 involves the excision of a lesion located in the tendon, tendon sheath, or joint capsule of the foot. Lesions that may be excised include cysts or ganglions, which are abnormal growths that can cause discomfort or functional impairment. During this procedure, a surgical incision is made over the area where the lesion is situated, allowing access to the affected tendon, tendon sheath, or joint capsule. The surgeon carefully dissects the surrounding soft tissues to expose the lesion, ensuring that it is meticulously separated from the healthy tissue surrounding it. This careful dissection is crucial to prevent damage to the adjacent structures and to ensure complete removal of the abnormal tissue. Once the lesion is fully excised, it is sent for pathology evaluation to determine its nature and to rule out any malignancy. Additionally, if there is inflamed synovial tissue present, it may be removed using a motorized suction shaving device, which aids in minimizing trauma to the surrounding tissues. This procedure is specifically indicated for lesions in the foot, and a different code, CPT® Code 28092, is used for similar procedures performed on the toes.
