Summary & Overview
CPT 95808: Technologist-Attended Polysomnography, Diagnostic Sleep Study
CPT code 95808 denotes a technologist-attended polysomnography, a diagnostic sleep study used to record biophysiological changes during sleep to identify sleep disorders. This code is widely used across hospital-based sleep centers and independent sleep laboratories and is central to diagnosing obstructive sleep apnea, central sleep apnea, periodic limb movement disorder, and other sleep-related conditions. Nationally, accurate coding for polysomnography affects access to diagnostic services and appropriate clinical follow-up.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for 95808, payer coverage considerations, common modifiers and billing caveats (where available), and benchmarking topics relevant to utilization and site-of-service patterns. The publication outlines how 95808 fits within the broader sleep medicine service line and highlights items to review when preparing claims or evaluating contracts.
This summary serves clinicians, billing professionals, and policy analysts seeking a national perspective on the role and documentation requirements of CPT code 95808. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 95808 represents a technologist-attended polysomnography (sleep study). This diagnostic service measures biophysiological changes that occur during sleep to help physicians diagnose sleep disorders such as sleep apnea, narcolepsy, and other sleep-related breathing or movement disorders.
Service type: Diagnostic sleep study (polysomnography) with technologist present
Typical site of service: Sleep laboratory or hospital-based sleep center, where technologists monitor the patient and recording equipment throughout the overnight or extended study period.
Clinical & Coding Specifications
Clinical Context
A 52-year-old male with obesity (BMI 34), daytime sleepiness, loud snoring reported by his partner, and witnessed apneas is referred by his primary care physician to a sleep center for diagnostic polysomnography. The patient arrives in the evening for an attended overnight sleep study. A sleep technologist performs setup, applies electrodes and sensors to monitor electroencephalography, electrooculography, electromyography, electrocardiography, respiratory effort, airflow, oxygen saturation, snoring, and body position. The technologist documents baseline vitals, calibrates equipment, monitors signal quality throughout the night, troubleshoots sensor dislodgement, and records annotated events (arousals, apneas, hypopneas) while the patient sleeps. The recorded data are transmitted to the interpreting physician for review the following day. The typical workflow includes intake and clinical history review, sensor application and equipment calibration by the technologist, overnight monitoring and event marking, equipment removal and data upload, and physician scoring and interpretation leading to a diagnostic report and treatment recommendations (for example, CPAP titration if obstructive sleep apnea is confirmed). Typical site of service is an accredited sleep laboratory or hospital-based sleep center where attended polysomnography is performed.
