Unlisted musculoskeletal procedure, diagnostic nuclear medicine

CPT4 code

Name of the Procedure:

Unlisted musculoskeletal procedure, diagnostic nuclear medicine


This is a diagnostic test used to assess various conditions affecting the bones and muscles, utilizing radioactive substances and specialized imaging technology to obtain detailed images of the musculoskeletal system.


The procedure aims to diagnose musculoskeletal issues, such as fractures, infections, tumors, and other abnormalities. It helps in forming a precise diagnosis to guide treatment decisions.


  • Persistent bone pain or unexplained musculoskeletal symptoms
  • Detection of bone infections or fractures not visible on standard X-rays
  • Evaluation of bone tumors or metastasis
  • Assessment of bone diseases like osteoporosis


  • Fasting for a few hours before the procedure may be required.
  • Patients may need to adjust or stop certain medications as directed by their doctor.
  • Initial blood tests or imaging studies might be needed to tailor the procedure.

Procedure Description

  • The patient receives an injection of a small amount of radioactive tracer.
  • After the injection, a waiting period of several hours is usually necessary for the tracer to accumulate in the target areas.
  • The patient then lies on a table while a special camera (gamma camera) captures images of the bones and muscles.
  • The procedure is non-invasive and typically doesn’t require anesthesia.


The waiting period between injection and imaging can range from 2 to 4 hours. Actual imaging typically takes around 30 to 60 minutes.


The procedure is performed in a hospital’s nuclear medicine department or at an outpatient imaging center.


  • Nuclear medicine physician
  • Radiologic technologist
  • Nurses or support staff for patient preparation and care

Risks and Complications

  • Common risks include slight discomfort at the injection site.
  • Rare risks include allergic reactions to the radioactive tracer or complications related to radiation exposure, which are generally minimal.


  • Provides detailed images for accurate diagnosis.
  • Helps detect issues that may not be visible with other imaging techniques.
  • Early and precise diagnosis can lead to more effective treatment.


  • Generally, no significant recovery time is needed.
  • Patients are encouraged to drink plenty of fluids to help flush out the radioactive tracer.
  • Normal activities can usually be resumed immediately following the procedure.


  • X-rays, MRI, or CT scans as alternative imaging modalities.
  • The choice of alternative depends on the specific condition and recommendation by the healthcare provider.

Patient Experience

  • The procedure is painless but may involve lying still for extended periods.
  • Some patients might feel slight discomfort during injection and mild apprehension due to the radioactive substance.
  • Pain management or comfort measures are typically unnecessary given the non-invasive nature of the procedure.
