Myelography is a specialized diagnostic imaging procedure that involves the use of contrast material to visualize the spinal cord and its surrounding structures. This technique is performed by injecting a contrast agent into the subarachnoid space, which is the area surrounding the spinal cord. The procedure is conducted under radiological supervision, utilizing real-time fluoroscopic X-ray imaging to monitor the flow of the contrast material. The radiologist carefully introduces a needle into the spinal canal to facilitate the injection of the contrast agent. As the contrast material disperses through the subarachnoid space, it enhances the visibility of critical anatomical structures, including the spinal cord, spinal canal, nerve roots, meninges, and blood vessels. This real-time imaging allows for immediate assessment of any abnormalities. Additionally, permanent X-ray images may be captured during the procedure for further analysis. Myelography is particularly useful in diagnosing various spinal conditions, such as intervertebral disc herniation, meningeal inflammation, spinal stenosis, tumors, and other lesions that may arise from infections or prior trauma. For coding purposes, CPT® Code 72240 specifically refers to myelography of the cervical spine, while other codes are designated for thoracic, lumbosacral, and multi-region examinations.

Myelography is indicated for a variety of spinal conditions that require detailed imaging to assess the integrity and functionality of the spinal structures. The following conditions may warrant the use of this diagnostic procedure:
The myelography procedure involves several critical steps to ensure accurate imaging and patient safety. The following outlines the procedural steps:
After the myelography procedure, patients are typically monitored for a short period to ensure there are no immediate complications. It is common for patients to experience mild discomfort or headache following the injection of the contrast material. Adequate hydration is encouraged to help flush the contrast agent from the body. Patients may be advised to rest and avoid strenuous activities for a specified period. Follow-up appointments may be scheduled to discuss the results of the imaging and any necessary further evaluations or treatments based on the findings.

| 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 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. | 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). | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | TC | Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles | 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). | 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.) | GC | This service has been performed in part by a resident under the direction of a teaching physician | GZ | Item or service expected to be denied as not reasonable and necessary | MG | The order for this service does not have applicable appropriate use criteria in the qualified clinical decision support mechanism consulted by the ordering professional | PC | Wrong surgery or other invasive procedure on patient | Q6 | Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | SA | Nurse practitioner rendering service in collaboration with a physician | 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 | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XP | Separate practitioner, a service that is distinct because it was performed by a different practitioner |
