Official Description

Excision first and/or cervical rib;

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 21615 refers to the surgical procedure known as the excision of the first and/or cervical rib. This procedure is typically performed under general anesthesia, ensuring that the patient is completely unconscious and free of pain during the operation. The process begins with the physician making a precise incision over the clavicle, which is the bone that connects the arm to the body. This incision allows the surgeon to access the rib that is to be excised. Once the rib is located, the surgeon carefully isolates it from surrounding tissues. The excision involves the use of specialized surgical instruments, including saws, to remove the rib from its articulation, which is the joint where the rib connects to the spine. After the rib has been successfully removed, the surgical site is thoroughly irrigated to clean the area and reduce the risk of infection. Finally, the incisions made during the procedure are closed, typically with sutures or staples, to promote healing. It is important to note that if the procedure also involves severing the sympathetic nerve pathway, a different code, CPT® Code 21616, should be used to accurately reflect the additional surgical intervention.

1. Indications

The excision of the first and/or cervical rib (CPT® Code 21615) is indicated for various clinical conditions that may necessitate the removal of the rib. These indications include:

  • Thoracic Outlet Syndrome - A condition characterized by compression of the nerves or blood vessels in the thoracic outlet, which can lead to pain, numbness, and weakness in the arms.
  • Cervical Rib Syndrome - Occurs when an extra rib develops above the first rib, potentially causing similar symptoms as thoracic outlet syndrome due to compression of surrounding structures.
  • Trauma or Injury - Situations where the rib may be fractured or otherwise damaged, necessitating surgical intervention for removal.

2. Procedure

The procedure for excising the first and/or cervical rib involves several critical steps, which are outlined as follows:

  • Step 1: Anesthesia Administration - The patient is placed under general anesthesia to ensure they are completely unconscious and free from pain during the procedure.
  • Step 2: Incision Creation - The surgeon makes a careful incision over the clavicle, which provides access to the rib that needs to be excised.
  • Step 3: Rib Isolation - Once the incision is made, the surgeon isolates the rib from surrounding tissues, ensuring that all necessary structures are protected during the excision.
  • Step 4: Rib Excision - Using surgical instruments, including saws, the surgeon removes the rib from its articulation, which is the joint where it connects to the spine.
  • Step 5: Site Irrigation - After the rib has been excised, the surgical site is irrigated to clean the area and minimize the risk of infection.
  • Step 6: Closure of Incisions - Finally, the incisions made during the procedure are closed using sutures or staples to promote healing.

3. Post-Procedure

Post-procedure care following the excision of the first and/or cervical rib involves monitoring the patient for any complications and managing pain. Patients are typically advised to rest and may be prescribed pain medication to alleviate discomfort. Follow-up appointments are essential to assess the healing process and to remove any sutures if necessary. Patients should also be educated on signs of infection or other complications that may arise, such as increased swelling or persistent pain, and instructed to contact their healthcare provider if these occur. Rehabilitation exercises may be recommended to restore mobility and strength in the affected area as the patient recovers.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
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).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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)
