2025 CPT code 94669

Mechanical chest wall oscillation to facilitate lung function, per session.

The code 94669 represents a single session of mechanical chest wall oscillation.Multiple sessions on the same day should be reported separately.If an E/M service is also performed on the same day, the appropriate E/M code should also be reported.

Modifiers may be applicable depending on circumstances (e.g., 59 for distinct procedural service, 25 for significant, separately identifiable E/M service).

Mechanical chest wall oscillation is medically necessary when manual techniques fail to effectively mobilize respiratory secretions or improve lung function in patients with conditions like cystic fibrosis, COPD, post-surgical atelectasis, or other respiratory disorders.

The physician or qualified healthcare professional is responsible for assessing the patient's respiratory status, determining the need for mechanical chest wall oscillation, applying the device correctly, monitoring the patient's response during and after the procedure, and documenting the treatment.

IMPORTANT May be used in conjunction with or as an alternative to manual chest wall percussion and vibration (CPT codes 94667 and 94668) if those methods are insufficient to improve lung function.

In simple words: The doctor uses a machine that gently vibrates the chest to help loosen and clear mucus from the lungs, making it easier to breathe.

Mechanical chest wall oscillation is performed to improve lung function by mobilizing secretions.This involves the use of a device, often resembling a vest, that applies oscillating compressive forces to the chest wall via a band placed around the patient's chest. This technique is employed when manual methods (cupping, percussing, vibration) prove insufficient.

Example 1: A patient with cystic fibrosis has excessive mucus buildup in their lungs, causing difficulty breathing.Manual chest physiotherapy has been ineffective.The physician orders mechanical chest wall oscillation (94669) to help mobilize secretions., A post-operative patient with atelectasis (lung collapse) is experiencing reduced lung function and increased secretions. The physician employs mechanical chest wall oscillation to improve lung expansion and secretion clearance., A patient with chronic obstructive pulmonary disease (COPD) experiences frequent episodes of increased mucus production and shortness of breath. Mechanical chest wall oscillation is used as an adjunct therapy to improve airway clearance and reduce dyspnea.

* Patient's medical history, including respiratory symptoms and previous treatments.* Physical examination findings, particularly respiratory assessment.* Rationale for choosing mechanical chest wall oscillation over manual techniques.* Documentation of the device used and the parameters of treatment (e.g., duration, frequency, intensity).* Patient's response to the treatment, including any improvements or adverse effects.

** This procedure may be performed by a respiratory therapist under physician supervision.
