(Active) Effective Date: N/A Cardiac Catheterization and Associated Procedures - Cardiovascular Procedures Medicine Feed
Physiologic exercise study (e.g., bicycle or arm ergometry) including assessing hemodynamic measurements before and after.
Modifiers may be applicable. Refer to guidelines for specific scenarios.
Medical necessity is established when the information obtained from the exercise study is essential for diagnosing or managing a cardiac condition and cannot be adequately assessed through resting measurements alone. The documentation should clearly indicate the clinical rationale for performing the study.
The physician inserts catheters and then has the patient exercise to increase heart rate.Hemodynamic measurements, including cardiac output, pressures, and oxygen saturation, are taken before, during, and after exercise.
In simple words: This procedure involves having the patient exercise while their heart is being monitored through a small tube (catheter). Measurements are taken before, during, and after exercise to see how the heart handles physical activity.
This code represents a physiologic exercise study, typically involving bicycle or arm ergometry, which includes the assessment of hemodynamic measurements both before and after the exercise. It is used in conjunction with cardiac catheterization to evaluate the heart's response to physical stress. This involves measuring parameters like cardiac output, blood flow, pressures, and oxygen levels.
Example 1: A patient with suspected coronary artery disease undergoes cardiac catheterization, including this exercise study, to evaluate blood flow to the heart during physical exertion., A patient with heart failure undergoes this procedure to assess the severity of their condition and how their heart performs under stress., A patient with a history of heart attack undergoes this procedure to evaluate the effectiveness of previous treatments and to guide further management.
Documentation should include details of the exercise protocol, hemodynamic measurements obtained (e.g., cardiac output, pressures, oxygen saturation), and the physician's interpretation of the findings.
