CPT® Code 20220

The procedure described by CPT® Code 20220 involves the biopsy of superficial bone structures, such as the ilium, sternum, spinous process, or ribs. This procedure is typically performed under local anesthesia, although general anesthesia may be used in certain cases. During the biopsy, a large needle is inserted into the targeted superficial bone area to extract a tissue sample for diagnostic purposes. The technique allows for the collection of bone tissue without the need for extensive surgical intervention. In instances where a biopsy of deeper bone structures is required, a different code (CPT® Code 20225) is utilized, which involves the use of an exploration needle to guide a smaller needle for sample collection. It is important to note that various approaches may be employed for vertebral biopsies, depending on the specific anatomical considerations. Generally, no closure of the site is necessary following the procedure, as it is minimally invasive.
