Will Insurance Pay for an In-Lab Sleep Study? Home Sleep Tests vs. Rest assured, we’ll handle that! Floyd Memorial Sleep Disorders Center experts work with insurance companies every day to obtain pre-authorizations for sleep studies. We will make the necessary calls and arrangements to satisfy the insurance requirements to obtain authorization before the patient is scheduled for a sleep study. Monitored In-Lab Sleep Studies All we need is the physician referral, and we’ll take it from there. Our office handles the entire process from the initial evaluation by a board certified sleep specialist, through the comprehensive sleep study and, if indicated, fitting the patient for a CPAP machine. We also perform the CPAP titration study and complete the required DME (durable medical equipment) orders required by insurance companies to cover the cost of the equipment. The accredited sleep experts at the Floyd Memorial Sleep Disorder Center can help you, or your patients, get a good night’s sleep.

There are major differences betwen the home sleep tests they provide and the traditional in-lab sleep studies administered in accredited facilities. This brochure will explain the important differences between the two types of sleep study. Home Testing May Produce Less than Optimal Results Because home testing relies upon the patient to correctly place the monitoring equipment on themselves, many overnight studies have suboptimal results. The patient may incorrectly place the monitors on themselves, or during their sleep, accidentally remove or shift the position of the equipment to give false readings, or no readings at all. Frequently, home studies require multiple nights of monitoring to achieve one full night with potentially usable data. When a patient has an in-lab monitored sleep study, the trained technician ensures the accurate placement of the equipment and can immediately correct or replace the monitors if the patient knocks them off or dislodges the placement. This allows “clean” results and greater data accuracy. Chain of Custody The Department of Transportation has been increasing the mandatory testing of commercial drivers for obstructive sleep apnea (OSA) and other sleep disorders. Many professional drivers fearful of losing their licenses may seek to fake a ‘passing grade’ on their sleep evaluation. There are patients who have been known to place home sleep study equipment onto their spouses or children in order to avoid detection of a sleep disorder. Some patients may also wear the equipment, but stay awake all night, in order to hide any breathing issues related to a sleep disorder. Only an in-lab study has the capability to fully monitor the patient to ensure accurate identity and results. False Negatives Studies have shown that people are not able to accurately determine how long it takes to fall asleep, how long they slept, if they had REM sleep (dreaming) or how often they awaken during the night. Most home sleep tests do not include EEG (electroencephalogram) testing which measures electrical activity of the brain, and only rely upon the patient’s guesses as to how much and what type of sleep they might have had. OSA is more severe during REM sleep in most patients. Some will only have sleep apnea during REM sleep, and not during any other stage of sleep. If the patient didn’t have much sleep during the study, or didn’t have REM sleep, the sleep test may result in a false negative. Only a full diagnostic in-lab sleep study can ensure proper electrode placement and accurate determination of sleep stages, total sleep time, sleep disturbances and the presence of REM sleep. False negative studies often result in serious sleep disorders going undiagnosed and untreated. Studies have also shown that OSA is almost always more severe in the supine (back) sleeping position. Many types of home testing equipment do not monitor the patient’s position during sleep. Even when the home testing equipment is recording the patient’s position, the data may not be correct because the position monitor may slip during the night, possibly indicating the patient slept on their back, when in fact they were on their side. In-lab, monitored sleep studies have trained technicians monitoring and correcting the position for the patient so the study will accurately determine the severity of OSA while sleeping on the back. Situations When Home Tests Should Not Be Administered Because of the limited and possible inaccuracy of the data from home studies, the American Academy of Sleep Medicine advises that patients with the following conditions should not have a home study. These patients should only have in-lab, monitored sleep studies: Patients with another significant medical condition including: •Congestive heart failure •Neuromuscular disease •Moderate to severe pulmonary disease Patients suspected to have other sleep disorders such as: •Central sleep apnea •Periodic limb movement disorder •Insomnia •Parasomnias •Narcolepsy What if a Patient Requires or Wants a Home Study? While many home study providers have appeared in recent years, few meet the exacting standards set forth by the American Academy of Sleep Medicine (AASM) to achieve accreditation. The Floyd Memorial Sleep Disorders Center is one of the few providers who have met these standards and is accredited by the AASM to perform out-ofcenter (home) sleep studies if they are required. Some insurance companies will not approve a full in-lab study if a patient does not have certain medical conditions. In this situation, we are able to provide a home study that is scored by a registered polysomnographer and read by an AASM diplomate to provide the most accurate results for diagnosing a sleep disorder.
