Summary & Overview
CPT 95800: Unattended Sleep Monitoring (Home Sleep Test)
CPT code 95800 represents unattended sleep monitoring — commonly known as a home sleep test — that records heart rate, blood oxygen concentration, respiratory activity, and sleep duration without a provider physically present. This code matters nationally as use of home sleep testing has expanded for diagnosing sleep-disordered breathing, offering a lower-cost, more convenient alternative to in-lab polysomnography and affecting utilization patterns across payers. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn what CPT code 95800 covers clinically and operationally, typical sites of service, and which major payers recognize or cover the service. The publication summarizes benchmarks and coverage context relevant to national billing practice, highlights common clinical applications for unattended sleep monitoring, and outlines the service type and typical care settings.

Clinical & Coding Specifications
Clinical Context
A 52-year-old patient with excessive daytime sleepiness and witnessed apneas is referred for an overnight unattended home sleep apnea test. The device records heart rate, oxygen saturation, respiratory airflow/effort, and sleep time. The patient receives device setup instructions in clinic, takes the portable monitor home, and returns it the next day. Data are downloaded and analyzed remotely; there is no physician physically present during the study. The clinical workflow includes order entry with diagnosis, device provision and patient education by sleep lab staff or a technologist, overnight unattended monitoring at home, return of equipment, data upload, scoring by a sleep technician, and interpretation and report generation by a sleep medicine physician or qualified provider for diagnostic or treatment decisions.
