Official Description

Myelography via lumbar injection, including radiological supervision and interpretation; lumbosacral

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Myelography is a specialized imaging technique utilized to obtain detailed visualizations of the spinal canal, spinal cord, and spinal nerve roots. This procedure employs real-time fluoroscopy in conjunction with X-ray imaging to create comprehensive images that assist in diagnosing various spinal conditions. The procedure is performed under the direct supervision of a radiologist, ensuring that the imaging is conducted safely and effectively. Myelography is particularly useful for identifying issues such as intervertebral disc herniation, spinal stenosis, tumors, infections, inflammation, and other lesions that may arise due to disease or trauma. During the procedure, the patient is typically positioned lying on their abdomen or side to facilitate access to the lumbar region of the spine. A spinal needle is carefully advanced into the spinal canal until cerebrospinal fluid (CSF) is observed flowing freely, indicating proper placement. Subsequently, a non-ionic contrast material is injected into the subarachnoid space, allowing for enhanced visualization of the spinal structures. The flow of the contrast dye is monitored through fluoroscopy, and X-rays are taken to document any abnormalities present. Upon completion of the procedure, the patient is returned to a comfortable position, and the imaging results are interpreted to guide further clinical decision-making.

1. Indications

Myelography via lumbar injection is indicated for a variety of conditions affecting the spinal region. The following are the explicitly provided indications for this procedure:

  • Intervertebral Disc Herniation - A condition where the disc between the vertebrae bulges or ruptures, potentially compressing nearby nerves.
  • Spinal Stenosis - The narrowing of the spinal canal, which can lead to pressure on the spinal cord and nerves.
  • Spinal Tumors - Abnormal growths within or around the spinal cord that may require evaluation for treatment planning.
  • Infection - The presence of infectious processes affecting the spinal structures, which may necessitate imaging for diagnosis.
  • Inflammation - Conditions that cause swelling and irritation of the spinal tissues, requiring detailed imaging for assessment.
  • Other Lesions - Various other abnormalities caused by disease or trauma that may affect the spinal canal and require further investigation.

2. Procedure

The myelography procedure involves several critical steps to ensure accurate imaging of the spinal structures. The following procedural steps are outlined:

  • Step 1: Patient Positioning - The patient is positioned either lying on their abdomen or side to provide optimal access to the lumbar region of the spine for the injection.
  • Step 2: Needle Insertion - Under fluoroscopic guidance, a spinal needle is carefully advanced into the spinal canal at the lumbar region. The correct placement is confirmed by observing a free flow of cerebrospinal fluid (CSF) from the needle.
  • Step 3: Contrast Material Injection - Once the needle is properly positioned, a non-ionic contrast material is injected through the needle into the subarachnoid space. This contrast dye enhances the visibility of the spinal structures during imaging.
  • Step 4: Monitoring Contrast Flow - The procedure table is then slowly tilted up or down to allow the contrast dye to flow within the subarachnoid space. The flow of the dye is continuously monitored using fluoroscopy to ensure proper distribution.
  • Step 5: Imaging Acquisition - After the contrast has been adequately distributed, X-rays are obtained to document any abnormalities present in the spinal canal, spinal cord, and nerve roots.
  • Step 6: Completion of Procedure - Once imaging is complete, the procedure table is returned to a horizontal position, and the patient is allowed to assume a comfortable position for recovery.

3. Post-Procedure

After the myelography procedure, patients are typically monitored for any immediate adverse reactions to the contrast material. It is common for patients to experience some discomfort or headache following the procedure, which may be managed with appropriate analgesics. Patients are usually advised to rest and hydrate adequately to help flush the contrast material from their system. Follow-up imaging or clinical evaluations may be scheduled to discuss the results of the myelography and any further necessary interventions based on the findings.

MUE 1
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
GC This service has been performed in part by a resident under the direction of a teaching physician
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
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).
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.
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.
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.
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.)
