Polysomnography vs. Sleep Studies - General Information
"Sleep studies and polysomnography refer to the
continuous and simultaneous monitoring and recording of various physiological
and pathophysiological parameters of sleep for 6 or more hours with physician
review, interpretation and report. The studies are performed to diagnose a
variety of sleep disorders and to evaluate a patient's response to therapies
such as nasal continuous positive airway pressure (NCPAP). Polysomnography is
distinguished from sleep studies by the inclusion of sleep staging which is
defined to include a 1-4 lead electroencephalogram (EEG), an electrooculogram
(EOG), and a submental electromyogram (EMG). Additional parameters of sleep
include: 1) ECG; 2) airflow; 3) ventilation and respiratory effort; 4) gas
exchange by oximetry, transcutaneous monitoring, or end tidal gas analysis; 5)
extremity muscle activity, motor activity-movement; 6) extended EEG monitoring;
7) penile tumescence; 8) gastroesophageal reflux; 9) continuous blood pressure
monitoring; 10) snoring; 11) body positions, etc."

Criteria for Coverage of Sleep Diagnostic Tests
All reasonable and necessary diagnostic tests given
for the medical conditions listed below are covered when the following criteria
are met:
-
The clinic is either affiliated with a hospital or is
under the direction and control of physicians. Diagnostic testing routinely
performed in sleep disorder clinics may be covered even in the absence of
direct supervision by a physician.
-
Patients are referred to the sleep disorder clinic by
their attending physicians, and the clinic maintains a record of the attending
physician's orders.
-
The need for diagnostic testing is confirmed by
medical evidence, e.g., physician examinations and laboratory tests.
Diagnostic testing that is duplicative of previous
testing done by the attending physician to the extent the results are still
pertinent is not covered because it is not reasonable and necessary under
§1862(a)(1)(A) of the Act.
Coding for Sleep Testing
Following is a list of common CPT codes for sleep
testing from the American Medical Association CPT 2002 Manual. Please note that
coverage guidelines for sleep diagnostic procedures may vary from region to
region. If you have questions, please obtain the policy from your local
Medicare carrier. All sleep diagnostic equipment may not perform all parameters
described by the CPT codes below. Please refer to the Sleep Studies vs.
Polysomnography section for further definition of the parameters described.
Report codes with a -52 modifier if less than 6 hours
of recording or in other cases of reduced services as appropriate.

Medical Conditions For Which Sleep
Testing is Covered
Sleep diagnostic testing is covered only if the
patient has the symptoms or complaints of one of the conditions listed below.
Most of the patients who undergo the diagnostic testing are not considered
inpatients, although they may come to the facility in the evening for testing
and then leave after their tests are over. The overnight stay is considered an
integral part of these tests.
Narcolepsy
This term refers to a syndrome that is characterized by abnormal sleep
tendencies, e.g. excessive daytime sleepiness or disturbed nocturnal sleep.
Related diagnostic testing is covered if the patient has inappropriate sleep
episodes or attacks (e.g., while driving, in the middle of a meal, in the
middle of a conversation), amnesiac episodes or continuous disabling
drowsiness. The sleep disorder clinic must submit documentation that this
condition is severe enough to interfere with the patient's well being and
health before Medicare benefits may be provided for diagnostic testing.
Ordinarily, a diagnosis of narcolepsy can be confirmed by three sleep naps. If
more than three sleep naps are claimed, you must submit persuasive medical
evidence justifying the medical necessity for the additional test(s). Use HCPCS
procedure codes (95828*) and 95808.
*Code 95828 deleted. Substitute codes 95807, 95808 or
95810.

Sleep Apnea
This is a potentially lethal condition where the patient stops breathing during
sleep. Three types of sleep apnea have been described (central, obstructive,
and mixed). The nature of the apnea episodes can be documented by appropriate
diagnostic testing. Ordinarily, sleep apnea can be diagnosed by a single
polysomnogram and EEG. If more than one such testing session is claimed, you
must submit persuasive medical evidence justifying the medical necessity for
the additional tests. Use HCPCS procedure codes (95828*) and 95822.
*Code 95828 deleted. Substitute codes 95807, 95808 or
95810.

Impotence
Diagnostic nocturnal penile tumescence testing may be covered, under limited
circumstances, to determine whether erectile impotence in men is organic or
psychogenic. Although impotence is not a sleep disorder, the nature of the
testing requires that it be performed during sleep. The tests ordinarily are
covered only where necessary to confirm the treatment to be given (surgical,
medical or psychotherapeutic). Ordinarily, a diagnosis may be determined by two
nights of diagnostic testing. If more than two nights of testing are claimed,
you must submit persuasive medical evidence justifying the medical necessity
for the additional tests. Have your medical staff review questionable cases to
ensure that the tests are reasonable and necessary for the individual. Use
HCPCS procedure code 54250. (See § 35-24 of the Coverage Issues Manual for
policy on coverage of Diagnosis and treatment of impotence.)

Parasomnia
Parasomnias are a group of conditions that represent undesirable or unpleasant
occurrences during sleep. Behavior during these times can often lead to damage
to the surroundings and injury to the patient or to others. Parasomnia may
include conditions such as sleepwalking, sleep terrors, and REM sleep behavior
disorders. In many of these cases, the nature of these conditions may be
established by careful clinical evaluation. Suspected seizure disorders as
possible causes of the parasomnia are appropriately evaluated by standard or
prolonged sleep EEG studies. In cases where seizure disorders have been ruled
out and in cases that present a history of repeated violent or injurious
episodes during sleep, polysomnography may be useful in providing a diagnostic
classification or prognosis. Use HCPCS procedure codes (95828*) and/or 95822.
*Code 95828 deleted. Substitute codes 95807, 95808 or
95810.

PSG for Chronic Insomnia is Not
Covered
Evidence at the present time is not convincing that
polysomnography in a sleep disorder clinic for chronic insomnia provides
definitive diagnostic data or that such information is useful in patient
treatment or is associated with improved clinical outcome. The use of
polysomnography for diagnosis of patients with chronic insomnia is not covered
under Medicare because it is not reasonable and necessary under § 1862(a)(1)(A)
of the Act.
Coverage of Therapeutic Sleep
Services
Sleep disorder clinics may at times render
therapeutic as well as diagnostic services. Therapeutic services may be covered
in a hospital outpatient setting or in a freestanding facility provided they
meet pertinent requirements for the particular type of services, are reasonable
and necessary for the patient, and are performed under the direct personal
supervision of a physician.
