How do you determine whether a bone biopsy would be considered superficial (20220) or deep (20225)?


The long descriptions for codes 20220 and 20225 include examples of what would normally fit in the superficial (i.e., ilium, sternum, spinous process, ribs) or deep (i.e., vertebral body, femur) category. The bones listed are not exclusive, if a bone biopsy is performed in another area a good test might be whether the bone can be felt or if it must be found by guidance. When unsure, ask the physician whether they would consider it superficial or deep.
