Official Description

Insertion of interlaminar/interspinous process stabilization/distraction device, without open decompression or fusion, including image guidance when performed, lumbar; second level (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 22870 involves the insertion of an interlaminar or interspinous process stabilization or distraction device specifically at the second level of the lumbar spine. This procedure is performed without open decompression or fusion and includes image guidance when applicable. The primary goal of this intervention is to stabilize and/or distract the neural foramen, which is the opening through which spinal nerves exit the vertebral column. The interlaminar devices are strategically placed adjacent to the lamina, utilizing two sets of wings that encircle the inferior and superior spinous processes to limit excessive movement. In contrast, interspinous spacers are small implants inserted between the spinous processes of the vertebrae and are expanded to alleviate pressure on the spinal nerves. This procedure is particularly indicated for adults suffering from spinal stenosis, which can lead to symptoms such as pain and neurogenic claudication. The surgical approach typically involves making a small incision over the targeted lumbar disc(s) and carefully dissecting through the subcutaneous tissue and surrounding structures to access the spine. The procedure is designed to enhance stability and relieve nerve compression, ultimately improving the patient's quality of life.

1. Indications

The procedure described by CPT® Code 22870 is indicated for patients experiencing specific conditions related to the lumbar spine. These indications include:

  • Spinal Stenosis - A narrowing of the spinal canal that can lead to pressure on the spinal cord and nerves, causing pain and discomfort.
  • Neurogenic Claudication - Symptoms such as pain, weakness, or numbness in the legs that occur with walking or prolonged standing, often relieved by sitting or bending forward.

2. Procedure

The procedure for the insertion of an interlaminar/interspinous process stabilization/distraction device at the second level of the lumbar spine involves several detailed steps:

  • Step 1: Incision and Access - A small incision is made over the targeted lumbar disc(s), and the incision is carried down through the subcutaneous tissue to access the underlying structures.
  • Step 2: Dissection - The dissection continues through the dorsolumbar fascia, which is located laterally to the midline. During this step, the multifidus muscle is carefully detached to allow access to the spine.
  • Step 3: Ligament Preservation - The supraspinous ligaments that are attached to the fascia are preserved to maintain structural integrity, while the ligamentum flavum is elevated and partially resected to facilitate access to the interspinous space.
  • Step 4: Resection of Laminae - The superior and inferior laminae of the vertebrae are partially resected to create sufficient space for the device insertion.
  • Step 5: Device Placement - Incrementally sized dilators are inserted across the intraspinous space, positioned close to the posterior border of the facet joint. A sizing instrument is then used to determine the appropriate size for the device, which is inserted between the spinous processes as anterior to the intralaminar space as possible.
  • Step 6: Securing the Device - The device is secured in place using screws to ensure stability and proper function.
  • Step 7: Closure - Drains may be placed before the surgical site is closed, ensuring that any excess fluid can be managed post-operatively.

3. Post-Procedure

After the procedure, patients are typically monitored for any immediate complications. Post-operative care may include pain management, physical therapy, and instructions for activity restrictions to promote healing. The expected recovery period can vary based on individual patient factors and the extent of the procedure performed. Follow-up appointments are essential to assess the effectiveness of the device and to monitor for any potential complications or adjustments needed in the post-operative care plan.

SG Ambulatory surgical center (asc) facility 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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. 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.
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).
