Official Description

Biopsy, bone, trocar, or needle; superficial (eg, ilium, sternum, spinous process, ribs)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The biopsy of superficial bone is indicated for various clinical scenarios where tissue diagnosis is necessary. The following conditions may warrant this procedure:

  • Bone Lesions The presence of abnormal bone lesions that require histological examination to determine the nature of the lesion.
  • Infectious Processes Suspected infections within the bone that necessitate sampling for microbiological analysis.
  • Bone Tumors Evaluation of suspected benign or malignant bone tumors to guide treatment decisions.
  • Unexplained Bone Pain Persistent bone pain of unknown origin that requires investigation through tissue sampling.

2. Procedure

The procedure for performing a superficial bone biopsy using CPT® Code 20220 involves several key steps:

  • Preparation The patient is positioned appropriately, and the area of the skin overlying the targeted bone is cleaned and sterilized to minimize the risk of infection. Local anesthesia is administered to ensure the patient’s comfort during the procedure.
  • Needle Insertion A large trocar or needle is carefully inserted into the superficial bone, such as the ilium, sternum, spinous process, or ribs. The physician ensures that the needle is positioned correctly to obtain an adequate sample of bone tissue.
  • Tissue Extraction Once the needle is in place, the physician withdraws the plunger to collect the bone tissue. The sample is then carefully removed from the needle for further analysis.
  • Post-Procedure Assessment After the tissue sample is obtained, the physician assesses the site to ensure there are no complications. Typically, no closure is required, as the procedure is minimally invasive.

3. Post-Procedure

Following the biopsy, patients are usually monitored for any immediate complications, such as bleeding or infection. Since the procedure is minimally invasive, recovery is generally quick, and patients can often resume normal activities shortly after. However, they may be advised to avoid strenuous activities for a short period to allow for proper healing. Follow-up appointments may be scheduled to discuss the biopsy results and any further management based on the findings.

X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
GC This service has been performed in part by a resident under the direction of a teaching physician
LT Left side (used to identify procedures performed on the left side of the body)
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period

77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
