Official Description

Radiopharmaceutical therapy, by intravenous administration

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Radiopharmaceutical therapy by intravenous (IV) administration is a specialized medical procedure that involves the use of radioactive substances to treat various diseases or conditions, particularly in oncology. This therapy necessitates the establishment of an intravenous access line, which allows for the direct delivery of a dose-specific radioisotope into the patient's bloodstream. Once administered, the radioisotope circulates through the body and targets specific organs or tissues that require treatment. The use of radiopharmaceuticals such as Strontium 99 (Metasron), Samarium 153 (Quadramet), and Radium-223 (Xofigo) is particularly notable in this context, as these agents are specifically indicated for alleviating bone pain associated with cancer metastasis. The therapeutic action of these radioisotopes is based on their ability to emit radiation that can destroy cancerous cells or alleviate pain, making this a critical option in the management of metastatic bone pain.

1. Indications

The indications for radiopharmaceutical therapy by intravenous administration include the following:

  • Cancer Metastasis to Bone This therapy is primarily indicated for patients experiencing bone pain due to cancer that has spread (metastasized) to the bones, providing symptomatic relief and potentially improving quality of life.

2. Procedure

The procedure for administering radiopharmaceutical therapy by intravenous administration involves several key steps:

  • Step 1: Establishing IV Access The first step in the procedure is to establish an intravenous access line. This is typically done by inserting a catheter into a suitable vein, allowing for the safe and effective administration of the radiopharmaceutical. Proper aseptic technique is crucial during this step to prevent infection.
  • Step 2: Administering the Radiopharmaceutical Once the IV access is established, a dose-specific radioisotope is injected into the bloodstream. The choice of radiopharmaceutical, such as Strontium 99 (Metasron), Samarium 153 (Quadramet), or Radium-223 (Xofigo), depends on the specific clinical scenario and the patient's needs. The injection is performed slowly to ensure proper distribution of the radioisotope throughout the circulatory system.
  • Step 3: Monitoring After the administration of the radiopharmaceutical, the patient is monitored for any immediate adverse reactions or side effects. This monitoring is essential to ensure patient safety and to address any complications that may arise during or after the procedure.

3. Post-Procedure

Post-procedure care for patients receiving radiopharmaceutical therapy includes monitoring for potential side effects, which may include fatigue, nausea, or localized pain at the injection site. Patients are typically advised to stay hydrated and may be instructed to avoid close contact with others for a specified period to minimize radiation exposure to others. Follow-up appointments may be scheduled to assess the effectiveness of the treatment and to manage any ongoing symptoms related to the underlying condition.

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.
GC This service has been performed in part by a resident under the direction of a teaching 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
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.
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
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
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
GA Waiver of liability statement issued as required by payer policy, individual case
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
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
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.
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.
