Symphony of Destruction

Sleep Review Magazine has a Podcast series on portable monitoring. The series starts off with a talk by Mary Susan Esther, MD, President-elect of the AASM. Dr. Esther's talk is followed by that of Dr. Chediak, current AASM President. In the coming days, talks will be added by industry representatives.

Local Coverage Decision for Home Testing for OSA

The local coverage decisions that will implement Medicare coverage for home testing are starting to come out. The following "Future LCD" appears to cover Indiana, New Jersey, New York, and Kentucky:
The diagnosis of sleep apnea may be made using the following modalities:
polysomnography (PSG) performed in a sleep laboratory; or
unattended home sleep monitoring device of Type II; or
unattended home sleep monitoring device of Type III; or
unattended home sleep monitoring device of Type IV, measuring at least three channels (CAG-00093R2)


CPT code 95806 (unattended sleep study) by definition involves the absence of a technologist. Unattended sleep studies must meet the CPT definition in order to bill CPT code 95806.
95806
SLEEP STUDY, SIMULTANEOUS RECORDING OF VENTILATION, RESPIRATORY EFFORT, ECG OR HEART RATE, AND OXYGEN SATURATION, UNATTENDED BY A TECHNOLOGIST


I expect LCD's covering other regions to be similar. The bottom line is that Type 4 devices can be used to diagnose osa and obtain coverage for cpap, but there is no reimbursement for the actual study. The reimbursement for a type 3 study (95806) is about $200.

Get 8 hours of sleep to lose weight



Carnie Wison agrees with me:

"Ever since I had my daughter, my focus is not on me; it's on her," says Wilson, who is currently a size 16. "For the past two-and-a-half years, I haven't slept. I am convinced there has to be a link between sleep deprivation and a slower metabolism ... the past year, my workouts have been lazy. I've been snacking on the wrong foods and not drinking enough water."

eHealthTech

The billing for my outpatient sleep practice as well as for Somnus Sleep Clinic (sleep studies) is done by eHealthTech. eHealthTech is stationed in MS, but handles medical billing and physician practice management across the country. I highly recommend eHealthTech to sleep physicians and sleep labs.

Confessions of a sleeping-pill junkie

MSNBC reports on an Ambien junkie (via Kevin MD):
Right off I had trouble adjusting to my new schedule. The workdays went by slowly and the evenings all too quickly, and by the time I got into bed, it was often midnight or later. Knowing I could get only six hours of sleep at the most, I would start to panic. Worrying about not sleeping kept me from sleeping, and by the time my alarm clock sounded, I was lucky if I’d gotten four hours.
So by the time I turned to the sleep aid Ambien for relief, I was desperate — and primed to become an addict.
And I started abusing it almost immediately: I ignored the prolific warnings on the package, called multiple doctors to get it, mixed it with alcohol and took more than the prescribed amount. The makers of this drug never intended it to be used in any of those ways. And neither did I.

Type 4 Devices for Home Testing for OSA

I received the press release below via email. The two main type 4 devices that meet CMS criteria for home testing for OSA are the Itamar Watch-PAT100 and the Resmed ApneaLink (with the optional oximeter). Neither device is acceptable by the AASM for accredited sleep centers. The AASM has approved certain type 3 devices for accredited sleep centers.
Press Release

Hold until 18:00 (13 March, 2008)

"Watch-PAT100 included as an accepted ambulatory device for Medicare and Medicaid beneficiaries"

Itamar Medical Inc. is pleased to report that the Centers for Medicare and Medicaid Services (CMS) has released today its final National Coverage Decision (NCD) where it has decided to cover the Watch-PAT 100 for home diagnosis of obstructive sleep apnea. This decision will make the Watch-PAT available to Medicare beneficiaries nationwide.

"Today's decision will mean that Medicare beneficiaries in the United States will have access to one of the most accurate, convenient, and cost-effective home sleep testing diagnostic device for sleep apnea," said Itamar Medical Inc. CEO Israel Schreiber. "Medicare now joins the Department of Veterans Affairs, Kaiser Permanente, and other organizations and physicians nationwide in recognizing the usefulness and benefits of Watch-PAT in the diagnosis of sleep apnea."

"The Watch-PAT is already a widely used home sleep testing device, and this coverage decision means that all Medicare beneficiaries suspected of having obstructive sleep apnea will have access to a device that was designed to provide uniquely convenient and comfortable use with proven accurate and reliable performance," said Gary Sagiv, Itamar Medical Inc's Vice President.

Another Update on Home Testing for OSA

Several weeks ago I posted that regional Medicare carriers in many states decided not to cover home testing. Apparently those decisions are not in effect and the new national decision takes precedence:
That's because CMS has not yet released its final decision on whether to cover at-home based sleep tests. The decision, expected March 13, will likely favor the proposal. Until then, local coverage policy cannot be updated, said Dr. Hughes."Until the rules change, the rules are what they are," he said.
So basically, the new CMS decision overrides any pre-existing rules, but now that there has been a national decision, local coverage policy can be updated (at least that's my understanding, it's a confusing issue).

Aetna Follows CMS Policy on Home Testing

Please see my earlier posts today about CMS approving home testing for OSA.

Aetna's Policy is very similar to Medicare's:

Aetna considers the diagnosis and treatment of obstructive airway disease medically necessary according to the criteria outlined below.
Diagnosis
Aetna considers any of the following diagnostic techniques medically necessary for members with symptoms suggestive of OSA:
Full-channel nocturnal polysomnography (NPSG) (Type I device) performed in a healthcare facility;
Unattended home sleep monitoring using a Type II, III, or IV device.
Split-night study NPSG in which the final portion of the NPSG is used to titrate continuous positive airway pressure (CPAP);
Note: On occasion, an additional full-night CPAP titration NPSG may be necessary if the split-night study did not allow for the abolishment of the vast majority of obstructive respiratory events or prescribed CPAP treatment does not control clinical symptoms.
Limited-channel NPSG for members with a high pretest probability of OSA (as suggested by the simultaneous presence of snoring, excessive daytime sleepiness, obesity, and observed apneas or nocturnal choking or gasping);
Video-EEG-NPSG (NPSG with video monitoring of body positions and extended EEG channels) to assist with the diagnosis of paroxysmal arousals or other sleep disruptions that are thought to be seizure related when the initial clinical evaluation and results of a standard EEG are inconclusive.

Thank you to my colleague in Ohio for sending me the link to Aetna's policy.

The Key Line in the CMS decision

Please see my post earlier today for the full CMS decision on Home Testing.

I found this line interesting:

unattended home sleep monitoring device of Type IV, measuring at least three channels

I only have a basic understanding of the main Type 4 device on the market, the Resmed ApneaLink. My understanding is that it utilizes a nasal pressure transducer. I just googled it and came up with this site:

http://www.resmed.com/en-us/products/clinical_systems/apnealink/apnealink.html?menu=products

It looks like there is an optional oximeter available, that adds 2 channels (pulse and oximetry) to the nasal pressure transducer channel, giving the required 3 channels.

Are most doctors who are currently using the Resmed ApneaLink also using the optional oximeter??? If anyone has some info about this device, please leave a comment. Thanks.

CMS Approves Home Testing for Obstructive Sleep Apnea

Decision Summary
We received a request to reconsider the 2005 National Coverage Determination (NCD) for CPAP Therapy for OSA (CAG-00093R) to allow coverage of CPAP based upon a diagnosis of OSA by home sleep testing (HST). After considering public comments and additional information, we are making the following changes to the NCD for CPAP. The revised indications and limitations NCD are noted in Appendix B.
Coverage of CPAP is initially limited to a 12 week period for beneficiaries diagnosed with OSA as subsequently described. CPAP is subsequently covered for those beneficiaries diagnosed with OSA whose OSA improved as a result of CPAP during this 12 week period.We remind the reader that Durable Medical Equipment, Prothetics, Orthotics, and Supplies (DMEPOS) suppliers are required to provide beneficiaries with necessary information and instructions on how to use Medicare-covered items safely and effectively. 42 CFR 424.57(c)(12). Failure to meet this standard may result in revocation of the DMEPOS supplier’s billing privileges. 42 CFR 424.57(d).
CPAP for adults is covered when diagnosed using a clinical evaluation and a positive:
polysomnography (PSG) performed in a sleep laboratory; or
unattended home sleep monitoring device of Type II; or
unattended home sleep monitoring device of Type III; or
unattended home sleep monitoring device of Type IV, measuring at least three channels

We remind the reader that, in general, pursuant to 42 CFR 410.32(a) diagnostic tests that are not ordered by the beneficiary’s treating physician are not considered reasonable and necessary. Pursuant to 42 CFR 410.32(b) diagnostic tests payable under the physician fee schedule that are furnished without the required level of supervision by a physician are not reasonable and necessary.
A positive test for OSA is established if either of the following criterion using the Apnea-Hypopnea Index (AHI) or Respiratory Distress Index (RDI) are met:
AHI or RDI greater than or equal to 15 events per hour, or
AHI or RDI greater than or equal to 5 and less than or equal to 14 events per hour with documented symptoms of excessive daytime sleepiness, impaired cognition, mood disorders or insomnia, or documented hypertension, ischemic heart disease, or history of stroke. The AHI is equal to the average number of episodes of apnea and hypopnea per hour. The RDI is equal to the average number of respiratory disturbances per hour.
If the AHI or RDI is calculated based on less than two hours of continuous recorded sleep, the total number of recorded events to calculate the AHI or RDI during sleep testing is at least the number of events that would have been required in a two hour period.
We are deleting the distinct requirements that an individual have moderate to severe OSA and that surgery is a likely alternative.

I wish to thank my colleague in Ohio for sending this to me.

Behavioral Sleep Medicine- Who Should Practice It?

I would like to thank Dr. Perlis for his thougtful response to my Saturday March 1 post. Since not everyone reads the comments, I think that Dr. Perlis's reply deserves its own post and am reprinting it below:

===========> Michael Perlis Reply RE: Michael Rack, MD Post #1169The Threat FROM Psychologists===========>
It is interesting that Dr. Rack phrased the subject to his email this way. I think many people who specialize in Behavioral Sleep Medicine would see this differently, i.e., be concerned about recent initiatives by the AASM as a THREAT TO the continued participation of Psychologists in Sleep Medicine.
MR: Has anyone read the editorial in this month's issue of JCSM by Michael Perlis, Phd? In this editorial about behavioral sleep medicine/CBT-insomnia, Dr. Perlis advocates for the requirement that all accredited sleep disorders centers be required to "have a provider on staff (full time or part time) who is BSM "boarded" or board eligible. ===========>

This was indeed one of many recommendations. There are two issues here. First, it is a fact that most accredited Sleep Disorders Centers (SDCs) do not have people who specialize in the assessment and tx of insomnia. Second, it is a fact that the people who are "boarded" in BSM specialize in the assessment and tx of insomnia and are the only Sleep Medicine clinicians with any certification to conduct CBT-I. So it follows that fully accredited SDCs
Given that the need to provide treatment for all sleep DXs Incl. insomnia
Given the desire to provide the highest standard of care possible
should have BSM "boarded" or board eligible on staff.

MR: I am a DABSM and also certified in sleep medicine by the ABIM. I have also passed the AASM behavioral sleep medicine certification exam, and so I periodically receive emails from Dr. Perlis regarding the issue of who can provide behavioral sleep medicine services (I am also a member of the behavioral sleep medicine committee, but I will not reveal those confidential discussions). There is a growing movement among psychologists who are upset because they are not eligible for the new physician sleep boards to require accredited sleep centers to have BSM-certified individuals (primarily psychologists) on staff.===========>
While there is a contingent of PhD clinicians that are indeed upset about not being eligible for the ABMS exam, this is not the main issue for BSM clinicians. In fact, this issue is old news. The BSM exam was designed and established by the original AASM Presidential Committee for BSM (of which I was a member) precisely to fill the void left by the closure of the ABMS to PhD clinicians. Note: Unlike the new Sleep Medicine Exam… The BSM exam is (and should continue to be) open to PhDs and MDsThe current debate is whether to extend the credentialing process to MA level clinicians (NPs, PAs, etc.). The commentary written by Dr. Smith and I airs out the issues related to this movement and how this might be achieved in a manner that guarantees the highest standards of care be maintained. Finally, please note that one of the recommendations made in our JCSM Commentary is that both BSM and ABMS certified individuals should supervise MA level clinicians.
MR: I encourage all sleep physicians to write the AASM Board of Directors and support the position that physician board certification in sleep medicine qualifies the physician to practice all aspects of sleep medicine, including behavioral sleep medicine. ===========>
There is no question that the certification in sleep medicine does indeed proffer the right for all such certified individuals to practice BSM. The real questions are
1. Do most MDs certified in sleep medicine feel themselves qualified to practice and/or supervise CBT-I and other BSM interventions ?
2. Do most MDs want to practice in this arena ? I think the answer to both questions would be an emphatic “No!”. Perhaps the best analogy, as I understand this, is that MD degree and license is sufficient to for any MD to conduct any form of medicine. So any MD, for example, can conduct assessments and treatment for sleep disorders. The question here, again, is should they ? Are they really qualified? Will they provide the best possible treatment? Like Dr. Rack – I also encourage you to engage these issues and, whatever your opinion, share them with the BSM section leaders and the AASM BOD.
MR: In addition, consider attending the Insomnia Section meeting at Sleep 2008. The Insomnia Section has become a center for psychologists who support Dr. Perlis's position.===========> Please do attend. Although if your expecting this to be a Perlis Supporter Che-Guevara-type meeting… you’ll likely be very disappointed. Sincerely Michael Perlis

Restless Legs Syndrome and Cardiovascular Disease

Dr. Poceta at Sleep Expert recently posted about the link between Restless Legs and Heart Attacks. It seems that restless legs syndrome isn't just an abnormal sensory/motor experience, it also has adverse health consequences:
In a recent blog post,
I reviewed a new study that showed an increased risk of heart disease in patients with restless legs syndrome (RLS). This study and others suggest that RLS, like sleep apnea, is more than just an unpleasant sleep disorder; such that RLS actually raises the chances of having a serious medical condition.
RLS is more than a feeling—patients with RLS have poor sleep and also have periodic limb movements (PLM's) during sleep.
PLM's are the repetitive movements of the foot, leg, and thigh that happen mostly during sleep in patients with RLS.

A recent study sheds some light on how and why RLS could lead to heart attacks—by raising blood pressure during the PLM's.
The study is published in the medical journal Clinical Neurophysiology in mid 2007.
I encourage you to read the full post at Sleep Expert, a revolutionhealth blog.

The Growing Threat from Psychologists

I recently posted the following in the American Academy of Sleep Medicine discussion forums. There is a growing movement among sleep psychologists to limit the ability of sleep physicians to practice the full aspect of sleep medicing. Specifically, some sleep psychologists are trying to make it a condition of sleep center accreditation that the sleep center has a practioner certified in behavioral sleep medicine (which is an AASM certificate examination) on staff. The AASM behavioral sleep medicine certification is primarily for psychologists, though some MD's, including myself, have taken and passed the exam.

Has anyone read the editorial in this month's issue of JCSM (The Feb issue of the Journal of Clinical Sleep Medicine) by Michael Perlis, PhD?
In this editorial about behavioral sleep medicine/CBT-insomnia, Dr. Perlis advocates for the requirement that all accreditied sleep disorders centers be required to "have a provider on staff (full time or part time) who is BSM "boarded" or board elgible.
I am a DABSM and also certified in sleep medicine by the ABIM. I have also passed the AASM behavioral sleep medicine certification exam, and so I periodically receive emails from Dr. Perlis regarding the issue of who can provide behavioral sleep medicine services (I am also a member of the behavioral sleep medicine committee, but I will not reveal those confidential discussions).
There is a growing movement among psychologists who are upset because they are not elgible for the new physician sleep boards to require accredited sleep centers to have BSM-certified individuals (primarily psychologists) on staff.
I encourage all sleep physicians to write the AASM Board of Directors and support the position that physician board certification in sleep medicine qualifies the physician to practice all aspects of sleep medicine, including behavioral sleep medicine. In addition, consider attending the Insomnia Section meeting at Sleep 2008. The Insomnia Section has become a center for psychologists who support Dr. Perlis's position.


Sleep psychologists are trying to force sleep disorders centers to hire them on staff, using AASM accreditation as the enforcement mechanism. Most sleep physicians, including myself, would have no problem with referring CBT-I (cognitive behavioral therapy for insomnia) cases out to qualified psychologists. We board-certified sleep physicians should not, however, be force to hire psychologists, nor be limited in our ability to practice the full spectrum of sleep medicine, including, if we choose, behavioral sleep medicine.
