Official Description

Laminectomy for excision of intraspinal lesion other than neoplasm, intradural; thoracic

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 63271 refers to a laminectomy performed for the excision of an intraspinal lesion that is not classified as a neoplasm, specifically located in the thoracic region. Intraspinal lesions can arise from various non-neoplastic conditions, which include infectious agents such as tuberculosis, syphilis, cytomegalovirus, herpes simplex virus, bacteria, or parasites. Additionally, non-infectious lesions may occur due to conditions like sarcoidosis, multiple sclerosis, or systemic lupus erythematosus. Inflammatory lesions, which can be caused by idiopathic necrotizing processes or radiation myelopathy, also fall under this category. During the laminectomy, the surgeon makes an incision in the skin over the thoracic area, extending down to the spinous processes to access the spine. The procedure involves retracting the muscles away from the lamina and facet joint, followed by the use of a bone drill to remove part or all of the lamina, thereby exposing the spinal cord. The surgeon then identifies the lesion within the dura mater, incises the dura over the lesion, and explores the extent of the lesion. A tissue sample may be collected for pathology examination to determine the nature of the lesion. Once identified, the lesion is meticulously dissected from the surrounding tissue using an operating microscope and is removed once it is completely free from adjacent structures. This procedure is critical for addressing various non-neoplastic conditions affecting the thoracic spine and ensuring proper patient management.

1. Indications

The laminectomy for excision of an intraspinal lesion other than neoplasm, intradural, is indicated for various conditions that involve non-neoplastic intraspinal lesions. These indications include:

  • Infectious Lesions These may be caused by pathogens such as tuberculosis, syphilis, cytomegalovirus, herpes simplex virus, bacteria, or parasites.
  • Non-Infectious Lesions Conditions such as sarcoidosis, multiple sclerosis, or systemic lupus erythematosus can lead to the formation of non-infectious intraspinal lesions.
  • Inflammatory Lesions These lesions may arise from idiopathic necrotizing processes or radiation myelopathy, necessitating surgical intervention.

2. Procedure

The procedure for CPT® Code 63271 involves several critical steps to ensure the successful excision of the intraspinal lesion:

  • Step 1: Incision The surgeon begins by making an incision in the skin over the thoracic region, which is the area where the intraspinal lesion is located. This incision is extended down to the spinous processes to provide adequate access to the spine.
  • Step 2: Muscle Retraction After the incision, the muscles are carefully retracted away from the lamina and facet joint to expose the underlying bony structures of the spine.
  • Step 3: Bone Removal A bone drill is utilized to remove part or all of the lamina, which is the bony arch of the vertebra. This step is crucial for exposing the spinal cord and the dura mater that encases it.
  • Step 4: Dura Mater Incision Once the spinal cord is exposed, the surgeon identifies the lesion within the dura mater. An incision is made in the dura over the site of the lesion to allow for direct access.
  • Step 5: Lesion Exploration The extent of the lesion is explored to assess its size and relationship to surrounding structures. This exploration may involve obtaining a tissue sample for pathology examination.
  • Step 6: Lesion Dissection and Removal After determining the nature of the lesion, the surgeon carefully dissects it away from the surrounding tissue using an operating microscope. Once the lesion is completely free from all surrounding tissue, it is removed from the body.

3. Post-Procedure

Post-procedure care following a laminectomy for excision of an intraspinal lesion typically involves monitoring the patient for any complications, managing pain, and ensuring proper recovery. Patients may require physical therapy to regain strength and mobility in the affected area. Follow-up appointments are essential to assess the surgical site and the patient's overall recovery. Additionally, if a tissue sample was taken for pathology, the results will guide further management and treatment options based on the nature of the lesion.

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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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).
