Official Description

Bone and/or joint imaging; limited area

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Bone and/or joint imaging using scintigraphy is a diagnostic procedure that employs a radiolabeled isotope tracer to visualize skeletal structures. This imaging technique is particularly useful for patients experiencing unexplained skeletal pain that may indicate conditions such as bone loss, infection, inflammation, or injury. Traditional radiographic methods, such as planar X-rays, may not always yield a definitive diagnosis, making scintigraphy a valuable alternative. The procedure begins with the establishment of an intravenous line, through which the radiolabeled isotope tracer is injected into the patient's circulatory system. In cases where inflammation is suspected, a blood sample is collected and processed to isolate white blood cells (WBCs). These WBCs are then tagged with radioactive calcium and reintroduced into the patient’s body. Following a designated waiting period, the patient is positioned on an imaging table, and a gamma camera is used to scan the specified limited area of interest. The imaging process involves capturing the radioactive energy emitted from the tracer, which is then transformed into detailed images for analysis. The physician interprets the results of the bone and/or joint imaging study and compiles a comprehensive written report outlining the findings. For coding purposes, if the imaging is limited to a specific area, the appropriate code to use is 78300. In contrast, if multiple areas are examined, code 78305 should be utilized, and for a full-body scan, code 78306 is applicable.

1. Indications

Bone and/or joint imaging using scintigraphy is indicated for patients presenting with specific symptoms or conditions that warrant further investigation. The following indications are explicitly recognized for this procedure:

  • Unexplained Skeletal Pain - Patients experiencing skeletal pain that cannot be attributed to a known cause may require this imaging to identify underlying issues.
  • Suspected Bone Loss - When there is a concern for potential bone loss, scintigraphy can help visualize changes in bone density and structure.
  • Infection - The procedure is useful in detecting infections within the bone or joint that may not be visible through traditional imaging methods.
  • Inflammation - In cases where inflammation is suspected, scintigraphy can provide insights into the inflammatory processes affecting the skeletal system.
  • Injury - Following an injury, if traditional radiographs do not reveal the extent of damage, scintigraphy can assist in diagnosing hidden fractures or other complications.

2. Procedure

The procedure for bone and/or joint imaging using scintigraphy involves several key steps that ensure accurate imaging and diagnosis. The following procedural steps are outlined:

  • Step 1: Establishing an Intravenous Line - The first step involves the placement of an intravenous (IV) line to facilitate the administration of the radiolabeled isotope tracer directly into the patient's circulatory system. This is a critical step as it allows for the effective delivery of the tracer needed for imaging.
  • Step 2: Injection of Radiolabeled Isotope Tracer - Once the IV line is established, the radiolabeled isotope tracer is injected. This tracer is essential for highlighting areas of interest within the bones and joints during the imaging process.
  • Step 3: Blood Sample Collection (if inflammation is suspected) - In cases where inflammation is a concern, a blood sample is drawn from the patient. This sample is then centrifuged to separate the white blood cells (WBCs), which are crucial for the next step.
  • Step 4: Tagging WBCs with Radioactive Calcium - The separated WBCs are tagged with radioactive calcium, enhancing their visibility during imaging. This step is particularly important for detecting inflammatory processes within the skeletal system.
  • Step 5: Re-injection of Tagged WBCs - After tagging, the radioactive WBCs are injected back into the patient. This allows the imaging to capture the areas where these cells migrate, providing valuable diagnostic information.
  • Step 6: Imaging Procedure - Following a prescribed waiting period to allow the tracer to circulate and accumulate in the targeted areas, the patient is positioned on the imaging table. A gamma camera is then used to scan the specified limited area of interest. The scanning process captures the radioactive energy emitted from the tracer, which is converted into images for analysis.
  • Step 7: Interpretation and Reporting - After the imaging is completed, the physician interprets the results of the bone and/or joint imaging study. A comprehensive written report is generated, detailing the findings and any relevant observations.

3. Post-Procedure

Post-procedure care for patients undergoing bone and/or joint imaging using scintigraphy typically involves monitoring for any immediate reactions to the radiolabeled tracer. Patients may be advised to hydrate adequately to help flush the radioactive material from their system. Additionally, they should be informed about any potential side effects, although these are generally minimal. The physician will provide the patient with the results of the imaging study during a follow-up appointment, where further management or treatment options may be discussed based on the findings. It is important for patients to follow any specific instructions given by their healthcare provider regarding activity levels and any additional imaging or tests that may be required.

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
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
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).
