Summary & Overview
CPT 95811: Polysomnography with PAP Initiation, Attended
CPT 95811 represents an attended polysomnography study that combines comprehensive sleep staging with multiple physiologic channels and the initiation of positive airway pressure therapy during the recording. This procedure is a key tool in diagnosing complex sleep-disordered breathing and initiating treatment during a single monitored night, making it clinically and operationally significant across the United States. Major national payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical purpose of the code, common billing and site-of-service considerations, and how CPT 95811 relates to adjacent polysomnography codes used for differing monitoring scopes and patient ages. The publication outlines billing nuances such as typical facility settings, common usage scenarios in sleep medicine and neurology practices, and links to related procedure codes for comparative context. It also highlights coding attributes relevant to payers and providers without issuing clinical recommendations. Data not available in the input for certain operational metrics (for example, service line metadata) is noted where applicable.
CPT Code Overview
CPT 95811 describes an attended polysomnography procedure that includes sleep staging with four or more additional physiologic parameters and the initiation of continuous positive airway pressure (CPAP) or bilevel ventilation during the study. This service is performed in the context of Sleep Medicine / Neurology and is typically delivered in a facility-based sleep laboratory setting (for example, POS 22 or POS 11). The procedure is attended by a technologist throughout the recording and is intended to document sleep architecture while initiating PAP therapy as part of the diagnostic and therapeutic evaluation.
Clinical & Coding Specifications
Clinical Context
A middle-aged adult with excessive daytime sleepiness, loud snoring, and witnessed apneas is referred to a sleep laboratory for attended in-lab polysomnography with auto-titration of positive airway pressure. The patient arrives in the evening and is evaluated by a sleep technologist and ordering sleep medicine physician. Standard sensors are applied for electroencephalography, electrooculography, electromyography, airflow, respiratory effort, oxygen saturation, and body position. During the study, diagnostic sleep staging is performed with four or more additional physiological parameters and continuous positive airway pressure (CPAP) therapy or bilevel ventilation is initiated and adjusted by the technologist under physician protocol. Monitoring continues until an adequate therapeutic response is achieved or the study is completed; results are reviewed by the interpreting physician and a report is generated for the referring provider.
