CPT® Code 94370

Deleted

1. Indications

The procedure associated with CPT® Code 94370 is indicated for various clinical scenarios where assessment of airway function is necessary. The following conditions may warrant the performance of this test:

• Assessment of Lung Function This test is utilized to evaluate the overall function of the lungs, particularly in patients with suspected obstructive or restrictive lung diseases.
• Diagnosis of Respiratory Conditions It aids in diagnosing conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other disorders that may affect airway dynamics.
• Monitoring of Disease Progression The procedure can be used to monitor changes in airway closing volume over time, providing insights into the progression of respiratory diseases.
• Preoperative Evaluation It may be indicated as part of a preoperative assessment for patients undergoing thoracic surgery or procedures that may impact lung function.

2. Procedure

The procedure for determining airway closing volume using CPT® Code 94370 involves several key steps that ensure accurate measurement and assessment of the patient's lung function. The following outlines the procedural steps:

• Step 1: Patient Preparation The patient is prepared for the test by ensuring they are in a comfortable position, typically seated. They may be instructed to avoid heavy meals or strenuous activity prior to the test to ensure optimal lung function during measurement.
• Step 2: Equipment Setup The necessary equipment, including a spirometer or similar device capable of measuring lung volumes, is set up and calibrated according to manufacturer specifications to ensure accuracy.
• Step 3: Instruction to the Patient The patient is given clear instructions on how to perform the test. They are typically asked to take a deep breath in, filling their lungs completely, and then exhale slowly and steadily into the device.
• Step 4: Measurement of Airway Closing Volume During the exhalation, the device records the volume of air exhaled and identifies the point at which the airways begin to close. This data is crucial for determining the airway closing volume.
• Step 5: Data Analysis The results are analyzed, and the airway closing volume is calculated. This information is then documented for further evaluation by the healthcare provider.

3. Post-Procedure

After the completion of the airway closing volume test, the patient may be monitored briefly to ensure they are feeling well and do not experience any adverse effects from the procedure. There are typically no specific post-procedure care requirements, as the test is non-invasive and does not involve any sedation or significant physical exertion. Patients can usually resume their normal activities immediately following the test. The results will be reviewed by the healthcare provider, who will discuss the findings with the patient and determine any necessary follow-up actions or additional testing based on the results obtained.
