Physiologic exercise study (eg, bicycle or arm ergometry) including assessing hemodynamic measurements before and after (List separately in addition to code for primary procedure)
CPT4 code
Name of the Procedure:
Physiologic Exercise Study (e.g., Bicycle or Arm Ergometry) with Hemodynamic Measurements
Summary
A physiologic exercise study involves exercising on a stationary bicycle or using arm ergometry while monitoring the body's response, especially heart and blood vessel function. This includes tracking hemodynamic measurements before and after exercise to assess cardiovascular health.
Purpose
The procedure is used to evaluate cardiovascular function under stress. It helps diagnose heart and blood vessel conditions, guide treatment plans, and assess exercise tolerance and capacity.
Indications
- Symptoms of chest pain or discomfort
- Shortness of breath
- Suspected coronary artery disease (CAD)
- Unexplained fatigue
- Pre-operative assessment for surgery
- Monitoring and managing known cardiovascular disease
Preparation
- Fasting might be required for a few hours before the test.
- Wear comfortable clothing and shoes suitable for exercise.
- Medication adjustments may be needed; follow your healthcare provider’s instructions.
- Baseline diagnostic tests like ECG or blood tests might be performed.
Procedure Description
- The patient is connected to monitoring equipment (ECG, blood pressure cuffs, and oxygen saturation sensors).
- Baseline hemodynamic measurements are recorded.
- The patient begins exercising on a stationary bicycle or using arm ergometry.
- Exercise intensity gradually increases while continuous monitoring is maintained.
- The patient exercises until a predetermined goal or symptom limit is reached.
- Post-exercise hemodynamic measurements are recorded.
- The patient cools down under observation.
Duration
The procedure typically takes about 30 to 60 minutes, including preparation and recovery time.
Setting
This procedure is generally performed in a hospital or outpatient clinic equipped with exercise and monitoring facilities.
Personnel
- Cardiologist or specialized physician
- Exercise physiologist or technician
- Nursing staff
Risks and Complications
- Common: Fatigue, muscle soreness
- Rare: Irregular heart rhythms, chest pain, heart attack
- Management of these risks involves immediate cessation of exercise and appropriate medical intervention.
Benefits
- Provides vital information on cardiovascular health.
- Helps in diagnosing heart conditions and planning treatments.
- Assesses success of ongoing treatment.
Recovery
- Patients can usually resume normal activities after a short period of rest.
- Follow any specific instructions given by your healthcare provider.
- Regular follow-up appointments may be advised.
Alternatives
- Pharmacologic stress testing (using medication to simulate exercise effects)
- Standard treadmill stress test
- Each alternative has its own set of pros and cons; your healthcare provider will choose based on your specific condition and health status.
Patient Experience
- You might feel exertion and breathlessness during the exercise.
- Some discomfort from the monitoring equipment is possible.
- Pain management and comfort measures will be provided throughout the procedure.
