Supply of injectable contrast material for use in echocardiography, per study

HCPCS code

Name of the Procedure:

Supply of Injectable Contrast Material for Use in Echocardiography, per study (HCPCS Code A9700)

Common name(s): Echocardiographic contrast, Echo contrast Technical or medical terms: Contrast echocardiography, Injectable ultrasound contrast agent


This procedure involves administering a special dye (contrast material) into the bloodstream to enhance the quality of ultrasound images of the heart during an echocardiogram. This helps in providing clearer and more detailed pictures of the heart's structure and function.


Medical Conditions or Problems It Addresses
  • Cardiac function assessment
  • Detection of heart abnormalities
  • Evaluation of blood flow within the heart
  • Identification of myocardial perfusion
Goals or Expected Outcomes
  • Improved visualization of heart structures
  • Enhanced diagnostic accuracy of echocardiograms
  • Better evaluation of cardiac health


Specific Symptoms or Conditions
  • Unclear or poor-quality standard echocardiogram images
  • Suspected heart abnormalities (e.g., defects, masses, clots)
  • Difficulty in assessing left ventricular function
  • Evaluation post-heart surgery or intervention
Patient Criteria or Factors
  • Patients with obesity or chronic lung disease affecting image quality
  • Patients undergoing stress echocardiography
  • When high precision in cardiac imaging is necessary for diagnosis or treatment planning


Pre-procedure Instructions
  • Patients may be advised to fast for a few hours before the echocardiogram.
  • Inform the healthcare provider of any allergies, especially to contrast materials.
  • Certain medications may need to be adjusted; follow the doctor’s specific guidance.
Diagnostic Tests or Assessments
  • A preliminary standard echocardiogram may be conducted to evaluate baseline images.
  • Review of patient’s medical history and current medications.

Procedure Description

Detailed Step-by-Step Explanation
  1. The patient lies on an examination table.
  2. An intravenous (IV) line is inserted, typically in the arm.
  3. The contrast material is injected through the IV line.
  4. As the contrast flows through the bloodstream, real-time ultrasound images are captured.
  5. The echocardiogram is performed using an ultrasound probe placed on the patient’s chest.
Tools, Equipment, or Technology
  • Ultrasound machine
  • Injectable contrast material
  • IV line and accessories
Anesthesia or Sedation Details
  • The procedure is typically performed without anesthesia.
  • Mild sedation may be used in rare cases.


The procedure, including the echocardiogram, typically takes about 45-60 minutes.


Performed in a hospital's echocardiography lab, outpatient clinic, or a specialized cardiac diagnostic center.


  • Cardiologist or echocardiography technician trained in administering contrast material and interpreting results.
  • Nursing staff to assist with IV insertion and patient monitoring.

Risks and Complications

Common Risks
  • Mild allergic reactions or side effects (e.g., nausea, headache, dizziness)
Rare Risks
  • Severe allergic reactions or anaphylaxis
  • Discomfort at the IV insertion site
Possible Complications and Their Management
  • Immediate medical attention for any allergic reactions.
  • Monitoring vital signs during and after the procedure.


Expected Benefits
  • Enhanced clarity of heart images, leading to more accurate diagnosis.
  • Improved ability to evaluate heart function and detect abnormalities.
Timeframe for Realization
  • Benefits are realized immediately as the enhanced images are available during the echocardiogram.


Post-procedure Care and Instructions
  • Monitor for any delayed allergic reactions.
  • Keep the IV site clean and dry.
Expected Recovery Time
  • Patients can usually resume normal activities immediately after the procedure.
Restrictions or Follow-up Appointments
  • No significant restrictions; follow up based on the echocardiogram results.


Other Treatment Options
  • Standard echocardiography without contrast
  • Other imaging modalities like cardiac MRI or CT scans
Pros and Cons of Alternatives
  • Standard echocardiography is less invasive but may provide less detailed images.
  • Cardiac MRI and CT scans are more detailed but more expensive and not as readily available.

Patient Experience

During the Procedure
  • Mild discomfort from IV insertion.
  • Feeling of cold or warmth as the contrast material is injected.
  • Lying still on the examination table.
After the Procedure
  • Minimal to no pain.
  • Immediate return to normal activities.
  • Follow any specific post-procedure instructions given by the healthcare provider.

Pain Management and Comfort Measures:

  • IV insertion site may be monitored for discomfort.
  • Patients are encouraged to communicate any discomfort during the procedure.
