Magnetic resonance imaging (MRI), specifically proton imaging, is a sophisticated noninvasive technique utilized to assess the blood supply within the bone marrow. This imaging modality leverages the magnetic properties of atomic nuclei, particularly protons found in hydrogen atoms, to generate detailed images of internal structures. When the body is subjected to radiowaves in a strong magnetic field, the protons resonate and emit radiofrequency signals. These signals are then captured and processed by a computer, which constructs high-resolution tomographic images in three-dimensional sections. During the procedure, the patient lies on a motorized table that moves into a large MRI scanner, allowing for comprehensive imaging of the bone marrow. The bone marrow itself is composed of a mixture of fat cells, which have a high water content, and non-fat cells. MRI is particularly effective in revealing changes in the bone marrow, as it can differentiate between normal and abnormal tissue based on the varying atomic actions of different tissue compositions and the distribution of blood cells within the medullary cavity of the bone. This capability is crucial for identifying conditions such as avascular necrosis and metastatic tumors, which can be visualized due to the distinct radiofrequency signal differences between healthy bone marrow and pathological tissues.

The procedure of magnetic resonance imaging (MRI) of the bone marrow blood supply is indicated for various clinical scenarios where detailed visualization of the bone marrow is necessary. The following conditions may warrant this imaging technique:
The procedure for magnetic resonance imaging of the bone marrow blood supply involves several key steps to ensure accurate imaging results. The following outlines the procedural steps:
Post-procedure care for patients undergoing magnetic resonance imaging of the bone marrow is typically minimal, as the procedure is noninvasive and does not involve radiation exposure. Patients are usually monitored briefly to ensure they are feeling well before leaving the facility. It is important for patients to follow any specific instructions provided by their healthcare provider regarding follow-up appointments or additional imaging if necessary. The results of the MRI will be interpreted by a radiologist, who will provide a detailed report to the referring physician for further evaluation and management of any identified conditions.

| 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. | 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 | Q1 | Routine clinical service provided in a clinical research study that is in an approved clinical research study | 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 | 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). | 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. | 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. | GC | This service has been performed in part by a resident under the direction of a teaching physician | GW | Service not related to the hospice patient's terminal condition | 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 | MH | Unknown if ordering professional consulted a clinical decision support mechanism for this service, related information was not provided to the furnishing professional or provider | 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 |
