CPT Code 95810 | Polysomnography (Evaluation Of Sleep Disorders)

Polysomnography (CPT code 95810) is a diagnostic procedure used to evaluate sleep disorders by monitoring various body functions during sleep.

What Is CPT Code 95810

Polysomnography (CPT code 95810) is a diagnostic procedure used to evaluate sleep disorders in patients six years or older.

It involves monitoring brain activity (EEG), heart activity (ECG), muscle activity (EMG), eye movement (EOG), respiration, and pulse oximetry during a period of six or more hours during the patient’s standard sleep period, typically at night.

The procedure is attended by a technologist and is used to diagnose a variety of sleep disorders and to evaluate a patient’s response to therapies such as continuous positive airway pressure (CPAP).

It can detect changes in body functions during different stages of sleep, including rapid eye movement (REM) and non-rapid eye movement (NREM). 

CPT 95810 can be used to diagnose sleep-related disorders such as sleep apnea, narcolepsy, parasomnia, restless leg syndrome, and periodic limb movements.

Description

The CPT book describes CPT code 95810 as: “Polysomnography; age six years or older, sleep staging with four or more additional parameters of sleep, attended by a technologist.”

Procedure

In this procedure, the provider performs a polysomnography exam for a six-year-old or older patient. 

The test is generally done during the regular sleep period of the patient at night. The provider monitors the sleep pattern of the patient over a period of six hours or more.

Along with an electroencephalogram (EEG) to monitor brain activity, at least four or more other parameters are monitored, such as electromyography (EMG) to monitor the muscles, electrooculogram (EOG) for the eyes, electrocardiogram (ECG) to monitor the heart, pulse oximetry and respiration, and other parameters. A technologist remains in attendance during the whole study.

The studies are performed to diagnose a variety of sleep disorders and to evaluate a patient’s response to therapies such as continuous positive airway pressure (CPAP).

The functions monitored include that of the brain (EEG), heart (ECG), muscles (EMG), eyes (EOG), respiration, and pulse oximetry.

The test is done during the regular sleep period of the patient, i.e., at night. Changes in the body functions are recorded at different stages of sleep, namely, the rapid eye movement (REM) stage and the non–rapid eye movement (NREM) stage.

Sleep–related disorders such as sleep apnea, narcolepsy, parasomnia, restless leg syndrome, or periodic limb movements produce different results in the test.

For example, sleep apnea is evident when there is restricted air intake and reduced blood oxygen level.

Similarly, abnormal leg movements during sleep may indicate restless leg syndrome. Polysomnography is distinguished from sleep studies by the inclusion of sleep staging.
