CPT 95811: Physician‑Monitored Extended Polysomnography (≥6 Hours)

CPT code 95811 designates a physician-monitored, attended polysomnographic study lasting six hours or more that records sleep patterns and multiple physiologic parameters. This extended diagnostic service is used to evaluate complex sleep-disordered breathing and other sleep-related physiologic abnormalities and is an important component of national sleep medicine practice and coverage frameworks. Key payers in the scope of this publication include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare.

Readers will find a concise explanation of the clinical role of 95811, how it differs from shorter or technologist-attended polysomnography services, and the typical settings in which it is delivered. The publication summarizes payer coverage considerations and common billing practices, highlights typical associated diagnoses that drive use of the service, and compares 95811 with related polysomnography codes used for younger patients or alternative parameter sets. The analysis also covers billing context such as frequently applied modifiers and applicable clinician specialties involved in service delivery.

This material is intended for a national audience of clinicians, coding professionals, and policy analysts seeking a clear operational and policy-oriented briefing on the CPT code 95811 and its role in diagnostic sleep medicine.

Billing Code Overview

CPT code 95811 describes a physician-monitored sleep study in which the clinician observes the patient’s sleep pattern and multiple physiologic functions over a continuous period of six hours or more. The service is a comprehensive, extended-duration attended sleep study focused on diagnosis and characterization of sleep-disordered breathing and related sleep physiology.

Service type: Attended, physician-monitored polysomnography (extended duration, ≥6 hours)

Typical site of service: Sleep laboratory or hospital-based sleep center

National Reimbursement Benchmarks

National comparisons show that Medicare’s mean rate of $492.4 sits below the BUCA average commercial mean of $1392.6, highlighting a substantial gap between Medicare reimbursement and the broader commercial benchmark. Blue Cross Blue Shield and UnitedHealth Group both have mean rates ($1947.8 and $694.2, respectively) that sit above Medicare, while Aetna ($528.5) and Cigna ($734.5) are closer to Medicare’s level but still generally higher.

Rate dispersion (P75 minus P25) varies meaningfully: Blue Cross Blue Shield has the widest interquartile spread at $600.0 (P75 $2147.4 minus P25 $1547.5), indicating high variability in commercial contracting, followed by UnitedHealth Group with a spread of $640.1 (P75 $970.1 minus P25 $309.0). The tightest spreads are seen with Aetna at $484.8 (P75 $720.8 minus P25 $213.6) and Cigna at $816.0 (P75 $1105.4 minus P25 $291.3) — note that while Cigna’s spread is larger than Aetna’s, it reflects different center points in their distributions.

Clinical & Coding Specifications

Clinical Context

A 52-year-old male with excessive daytime sleepiness, loud snoring, and witnessed apneas is referred to a sleep center for diagnostic polysomnography with physician monitoring extending six hours or more (CPT 95811). The physician reviews the referral, assesses history and comorbidities (hypertension, obesity), and documents the indication such as suspected obstructive sleep apnea (G47.33) or central sleep apnea (G47.31). The patient arrives at the outpatient sleep lab in the evening. A sleep technologist places EEG, EOG, chin and limb EMG, airflow sensors, respiratory effort belts, pulse oximetry, and ECG leads. The physician supervises electrode placement as needed, is available during the overnight attended study, monitors physiologic signals in real time, interprets events, and documents findings and a preliminary impression. The study continues for six hours or more to capture multiple sleep cycles. After study completion, the physician reviews scored data, finalizes the interpretation, and issues a report with apnea–hypopnea index, arousal index, sleep architecture, and recommendations for further testing or therapy initiation. Typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare. Typical site of service is an outpatient sleep laboratory or hospital sleep center. Typical providers include Sleep Medicine, Pulmonary, Internal Medicine, Family Medicine, or Psychiatry physicians with sleep credentialing.

`76`	Repeat procedure by same physician	Data not available in the input.
`77`	Repeat procedure by another physician	Data not available in the input.
`22`	Increased procedural services	Use when documentation supports unusually high complexity or work beyond typical for interpretation/monitoring.
