Clinical & Coding Specifications
Clinical Context
A patient presents to the office with symptoms of acute airway obstruction, such as wheezing, shortness of breath, or productive cough. The provider determines that an inhalation treatment is necessary to relieve airway obstruction or to induce sputum for diagnostic evaluation. The procedure is performed using an aerosol generator, nebulizer, metered dose inhaler, or intermittent positive pressure breathing (IPPB) device. The clinical workflow involves assessment, administration of the inhalation treatment, monitoring of the patient's response, and documentation of the procedure. This service is typically provided by a respiratory therapist or pulmonary function technologist in an office setting.
