Official Description

Infusion or instillation of radioelement solution (includes 3-month follow-up care)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 77750 involves the infusion or instillation of a radioelement solution, which is a specialized treatment primarily used in the context of brachytherapy. Brachytherapy is a form of radiation therapy where a radioactive source is placed inside or very close to the area requiring treatment. In this case, the radioelement solution is delivered intravenously, allowing for targeted distribution within the body, particularly to the bones and intestines. This method is particularly beneficial for patients suffering from prostate cancer that has metastasized to the bone, as well as those with cranial tumors. The radioelement solution is designed to be toxic to malignant cells, effectively targeting cancerous tissues while minimizing damage to surrounding healthy tissues. The administration of the solution can be performed through a peripheral vein or a central line, and it can be delivered either as an intravenous push or via a continuous drip. Importantly, the procedure also includes a follow-up care period of three months, ensuring that patients receive the necessary monitoring and support following the treatment.

1. Indications

The infusion or instillation of a radioelement solution, as described by CPT® Code 77750, is indicated for specific medical conditions where targeted radiation therapy is beneficial. The following are the primary indications for this procedure:

  • Prostate Cancer with Bone Metastasis This procedure is utilized in patients diagnosed with prostate cancer that has spread to the bones, allowing for localized treatment of malignant cells.
  • Cranial Tumors The infusion may also be indicated for individuals with cranial tumors, where the radioelement solution can effectively target and treat cancerous tissues in the cranial region.

2. Procedure

The procedure for the infusion or instillation of a radioelement solution involves several critical steps to ensure effective delivery and patient safety. The following outlines the procedural steps:

  • Step 1: Establishing Intravenous Access The first step in the procedure is to establish intravenous access. This can be achieved through a peripheral vein or a central line, depending on the patient's condition and the duration of the infusion required. Proper aseptic technique is essential to minimize the risk of infection during this process.
  • Step 2: Preparation of the Radioelement Solution Once intravenous access is secured, the radioelement solution is prepared for administration. This involves ensuring that the solution is correctly dosed and ready for infusion, adhering to safety protocols to handle the radioactive material.
  • Step 3: Administration of the Solution The radioelement solution is then administered to the patient. This can be done either as an intravenous push, where the solution is injected directly into the bloodstream, or through a continuous drip, allowing for a steady infusion over a specified period. The method of administration may depend on the specific treatment plan and the patient's needs.
  • Step 4: Monitoring During Infusion Throughout the infusion process, the patient is closely monitored for any adverse reactions or complications. Vital signs and overall patient response are assessed to ensure safety and efficacy of the treatment.
  • Step 5: Post-Infusion Care After the infusion is complete, the patient may require additional monitoring and care. This includes assessing for any immediate side effects and providing instructions for follow-up care, which is included in the three-month post-procedure period.

3. Post-Procedure

Following the infusion or instillation of the radioelement solution, patients are typically monitored for any immediate reactions to the treatment. The three-month follow-up care included in the procedure encompasses regular assessments to evaluate the effectiveness of the treatment and to monitor for any potential side effects or complications. During this follow-up period, healthcare providers may conduct imaging studies or other evaluations to determine the response of the cancer to the therapy. Patients are also advised on any necessary precautions regarding the handling of bodily fluids, as the radioelement solution is excreted in urine and feces. This follow-up care is crucial for ensuring the patient's ongoing health and addressing any concerns that may arise after the procedure.

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.
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.
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.)
