Official Description

Partial excision of posterior vertebral component (eg, spinous process, lamina or facet) for intrinsic bony lesion, single vertebral segment; each additional segment (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 22103 refers to the procedure of partial excision of a posterior vertebral component, which may include structures such as the spinous process, lamina, or facet, specifically for the treatment of an intrinsic bony lesion located within a single vertebral segment. This procedure is typically indicated when there is a need to remove a bony growth, such as a bone spur, that is causing discomfort or other complications. The process begins with the physician making an incision over the affected vertebral segment, which allows access to the underlying structures. The incision is carefully extended through the paravertebral muscles to reach the lesion. Once the lesion is exposed, the physician excises the affected portion of the vertebral segment, thereby alleviating the issue. After the excision, the incision is then closed. It is important to note that this code is specifically for the first segment treated, and additional segments that may require similar excision are coded separately, with the primary procedure being indicated by the appropriate CPT® codes for cervical, thoracic, or lumbar segments, namely codes 22100, 22101, and 22102 respectively.

1. Indications

The procedure described by CPT® Code 22103 is indicated for the removal of intrinsic bony lesions located in the posterior components of the vertebrae. These lesions may present as bone spurs or other bony growths that can lead to pain, discomfort, or neurological symptoms due to their proximity to spinal structures. The specific indications for this procedure include:

  • Bone Spurs These are bony projections that develop along the edges of bones, often in response to joint damage or degeneration, and can cause pain or restrict movement.
  • Intrinsic Bony Lesions These are abnormal growths or formations within the bone that may require surgical intervention to alleviate symptoms or prevent further complications.
  • Spinal Stenosis This condition involves the narrowing of the spinal canal, which can lead to pressure on the spinal cord and nerves, necessitating the removal of bony structures that contribute to the narrowing.

2. Procedure

The procedure for CPT® Code 22103 involves several key steps that ensure the effective excision of the bony lesion. The steps are as follows:

  • Step 1: Incision The physician begins by making a precise incision over the vertebral segment that contains the bony lesion. This incision is strategically placed to provide optimal access to the affected area while minimizing damage to surrounding tissues.
  • Step 2: Dissection Following the incision, the physician carefully dissects through the paravertebral muscles. This step is crucial as it allows the surgeon to reach the underlying vertebral structures without compromising the integrity of the surrounding muscles and tissues.
  • Step 3: Excision of the Lesion Once the lesion is adequately exposed, the physician excises the affected portion of the vertebral segment. This excision is performed with precision to ensure complete removal of the bony lesion while preserving as much healthy vertebral structure as possible.
  • Step 4: Closure After the excision is complete, the physician proceeds to close the incision. This involves suturing the layers of tissue back together to promote healing and restore the integrity of the back.

3. Post-Procedure

Post-procedure care following the excision of a bony lesion using CPT® Code 22103 typically involves monitoring the patient for any signs of complications, such as infection or excessive bleeding. Patients may be advised to limit physical activity for a specified period to allow for proper healing. Pain management strategies may be implemented to address any discomfort following the surgery. Follow-up appointments are essential to assess the healing process and to determine if any further interventions are necessary. Additionally, the physician may provide specific instructions regarding wound care and signs to watch for that could indicate complications.

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.
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.
73 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure prior to the administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may cancel a surgical or diagnostic procedure subsequent to the patient's surgical preparation (including sedation when provided, and being taken to the room where the procedure is to be performed), but prior to the administration of anesthesia (local, regional block(s) or general). under these circumstances, the intended service that is prepared for but cancelled can be reported by its usual procedure number and the addition of modifier 73. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
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).
