Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with chronic obstructive pulmonary disease (COPD) and reduced exercise tolerance attends a scheduled outpatient pulmonary rehabilitation session billed as 94625. The session is provided in an ambulatory clinic-based pulmonary rehabilitation program staffed by a respiratory therapist and a pulmonary physician or advanced practice provider. Typical workflow: intake vitals and brief symptom review, supervised exercise training (walking or cycle ergometer), breathing technique coaching, and education on inhaler use and energy conservation. Continuous oximetry is not used during the session; intermittent pulse oximetry checks may be performed for safety. Documentation includes start and stop times, targeted exercises, patient tolerance, education topics covered, and any adverse events. The session supports ongoing disease management after an acute exacerbation or as chronic disease maintenance, and is scheduled under the outpatient rehabilitation service model with expected durations per program policy.
