Clinical Policy Bulletin: Apnea Monitors for Infants
Aetna considers apnea monitors medically necessary durable medical equipment (DME) for infants less than 12 months of age with documented apnea or who have known risk factors for life threatening apnea according to the following indications:
Diagnosis of pertussis, with positive cultures, upon discharge from acute care facility. If monitored for pertussis, use of an apnea monitor is considered medically necessary for up to 1 month post diagnosis.
Documented apnea accompanied by bradycardia to less than 80 beats per minute; use of an apnea monitor is considered medically necessary until the infant remains event free for 6 weeks.
Documented apnea accompanied by marked hypotonia; use of an apnea monitor is considered medically necessary until the infant remains event free for 6 weeks.
Documented apnea accompanied by oxygen desaturation (oxygen saturation below 90 %), cyanosis or pallor; use of an apnea monitor is considered medically necessary until the infant remains event free for 6 weeks.
Documented gastro-esophageal reflux disease that results in apnea, bradycardia, or oxygen desaturation, until the infant remains event free for 6 weeks.
Documented prolonged apnea of greater than 20 seconds in duration; use of an apnea monitor is considered medically necessary until the infant remains event free for 6 weeks.
Infants with an apparent life-threatening event (ALTE), defined as an episode that is characterized by some combination of apnea (central or occasionally obstructive), color change (usually cyanotic or pallid but occasionally erythematous or plethoric), marked change in muscle tone (usually marked limpness), choking, or gagging. If monitored due to ALTE, use of an apnea monitor is considered medically necessary until the baby remains event free for 6 weeks.
Infants with apnea of prematurity, defined as sudden cessation of breathing that lasts for at least 20 seconds or is accompanied by bradycardia (heart rate less than 80 beats/min) or oxygen desaturation (oxygen saturation less than 90 % or cyanosis) in an infant younger than 37 weeks' gestational age. Continued use is considered medically necessary until they are past a post-conceptional age of 43 weeks and are event free for 6 weeks.
Infants with bradycardia on caffeine, theophylline, or similar agents, until event free for 6 weeks off medication.
Infants with chronic lung disease (bronchopulmonary dysplasia), especially those requiring supplemental oxygen, continuous positive airway pressure, or mechanical ventilation*.
Infants with neurologic or metabolic disorders affecting respiratory control (medical necessity reviewed on an individual case basis)*.
Infants with tracheostomies or anatomic abnormalities that make them vulnerable to airway compromise (medical necessity reviewed on an individual case basis)*.
Later siblings of infants who died of sudden infant death syndrome (SIDS), use of an apnea monitor is considered medically necessary until the later siblings are 1 month older than the age at which the earlier sibling died and they remain event free.
Aetna considers infant apnea monitors experimental and investigational for all other indications because their effectiveness for indications other than the ones listed above has not been established.
Aetna considers the use of remote infrared sensor for the detection of infant sleep apnea experimental and investigational because its effectiveness for has not been established.
* Except as specified for certain indications noted above, infant apnea monitors are usually considered medically necessary for approximately 3 months. Continued use of an apnea monitor is considered medically necessary for the durations noted in this policy, even when infants reach 12 months of age during the course of specified medically necessary duration of use.
The later siblings of infants who died of SIDS present a unique emotional and clinical dilemma. Many clinicians suggest monitoring such infants until they are 1 month older than the age at which the sibling died, and remain event free, although such use is not directly supported by specific evidence in the peer-reviewed medical literature. Aetna considers apnea monitors medically necessary in such circumstances.
The term “post-conceptional age” is defined as gestational age at birth plus age in weeks from birth. According to the American Academy of Pediatrics, this is more accurately designated as “postmenstrual age”.
Types of Monitors/Studies:
Because of the capabilities of a smart monitor, continuing sleep studies and pneumograms are not typically necessary. Should the ordering doctor wish to continue obtaining pneumograms for a child on a smart monitor, Aetna will alert the ordering doctor that continued use of a smart monitor is not considered medically necessary. Aetna considers a regular apnea monitor medically necessary for the duration of time that the doctor continues to want ongoing studies.
This policy is supported by a statement by the American Academy of Pediatrics (2003) on home apnea monitoring of infants.
There are 3 types of infant apnea: (i) central, (ii) obstructive, and (iii) mixed central and obstructive apnea. In central or diaphragmatic apnea, the infant makes no effort to breathe; the chest is still, and no air passes through the mouth or nose. In obstructive apnea, the chest is moving but no air passes through the mouth or nose (usually due to soft tissue such as the tongue blocking the upper airway). In mixed apnea, the infant has episodes of both central and obstructive apnea all within the same event. Most home infant apnea monitors measure chest movements and heart rate. Normally, the monitor's alarm is set to go off if the infant stops breathing for 20 seconds or if the heart rate slows to less than 80 beats/min (Stehlin, 1991).
Bani Amer and colleagues (2010) presented a contactless method for monitoring infant sleep apnea. The method uses a remote infrared sensor to monitor the motion of the infant's abdomen. According to the developers, this method has potential important clinical advantages in comparison with conventional methods. First, it has the potential to improve the comfort and compliance of the infants. Second, it may eliminate the effects of motion artefacts and skin irritation. Third, it may enhance infant safety. Fourth, it does not require frequent calibration and thus enables a continuous monitoring of sleep apnea. Finally, it is suitable for home applications. Experimental evaluation of this method showed that it has 85 % accuracy, 85.71 % specificity and 84.62 % sensitivity, which imply that it is a promising technique for the detection of infant sleep apnea.
