CPT 3274F: Sleep Apnea Evaluation Result from Overnight Testing

CPT code 3274F denotes a documented clinical finding related to sleep-disordered breathing used in sleep medicine and respiratory care; it represents a specific sleep apnea evaluation result typically generated from overnight polysomnography or home sleep testing and is associated with interpretation and reporting of nocturnal respiratory events, oxygen desaturation, and apneic/hypopneic indices. The service type is diagnostic sleep study reporting and the typical site of service is an outpatient sleep laboratory or home sleep testing setting.

For related coverage guidance, see recent payer policy updates: Diagnostic Testing Of Iron Homeostasis & Metabolism, Gamma-glutamyl Transferase (GGT) Testing in Adults, Venous and Arterial Thrombosis Risk Testing.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting to pulmonary medicine or thoracic surgery clinic with suspected obstructive sleep apnea, chronic hypoventilation, or unexplained daytime somnolence requiring objective assessment of nocturnal respiratory events. The clinical workflow begins with an outpatient visit documenting symptoms (snoring, witnessed apneas, daytime sleepiness), relevant comorbidities (obesity, COPD, neuromuscular disease), and ordering a diagnostic sleep study or overnight oximetry per facility protocol. The patient receives pretest instructions (medication, alcohol, caffeine avoidance) and undergoes monitoring at a sleep laboratory or at home with portable monitoring equipment. Technologists apply sensors, monitor data quality overnight, and a sleep medicine physician reviews and interprets the recorded respiratory, oxygenation, and airflow data to generate a report used for diagnosis and treatment planning (e.g., CPAP initiation, supplemental oxygen, referral for advanced testing). Typical sites of service include an accredited sleep center (polysomnography lab) or the patient's home when portable monitoring is appropriate.
