CPT® Code 94668

The procedure described by CPT® Code 94668 involves the manual manipulation of the chest wall, which is performed to enhance lung function by breaking up secretions within the lungs. This technique is particularly beneficial for patients who may have difficulty clearing mucus or other secretions due to various respiratory conditions. The manipulation is executed using the hands or a hand-held oscillating device, allowing for targeted treatment of specific lung areas. During the procedure, the patient is positioned either lying down or sitting up, which facilitates the use of percussion, vibration, and gravity to effectively dislodge secretions. The respiratory therapist or qualified healthcare professional employs cupped hands to create a forceful, rhythmic percussion against the chest wall, focusing on the lung regions that require drainage. Following this, vibration is applied by placing flat hands over the targeted lung area and moving the chest musculature to create vibrations that further assist in loosening secretions. After the percussion and vibration techniques, the patient is encouraged to take deep breaths, which helps to maximize air intake into the lungs. This is often followed by a forced exhalation to stimulate the cough reflex, aiding in the clearance of the airways. If the patient finds coughing too exhausting, an alternative technique called huffing can be utilized, where the patient takes a deep breath and forcefully exhales to help clear the airways. The entire process is repeated with the patient in various positions to ensure comprehensive treatment of all lung areas that require manipulation. It is important to note that CPT® Code 94667 is used for the initial demonstration of the procedure and/or the initial evaluation of the caregiver performing the manipulation, while CPT® Code 94668 is specifically designated for evaluation and treatment on subsequent days.
