Check your bills closely if you use this practice. I was billed for a high-level, complex 1+ hour visit, but my own location logs prove I was only in the building for 42 minutes total—meaning the actual face-to-face time with the doctor was a fraction of that. When I requested a formal billing audit and a copy of my electronic record timestamps to verify the doctor's actual time in the room, the office dragged its feet for two months, ignored my compliance inquiries, and continued to send me automated bills. When they finally responded, it was through an outside attorney who flatly refused to adjust the bill or provide the requested tracking logs, or my medical information which is against the law. Complete lack of billing integrity and transparency.

Dr. Keith Schwarz at ENT Specialist of the Rockies is truly outstanding. I have worked with Dr. Schwarz for six years now and have had nothing but positive results, both with my sleep apnea and other ENT-related issues. I trust him so much that even though I now live in Arizona and also work with an ENT here, I still travel back and forth to continue care with Dr. Schwarz. In my opinion, Dr. Schwarz is the best in the business. I highly recommend him to anyone looking for an experienced, knowledgeable, and trustworthy ENT specialist.

Dr. Rasband is extremely professional and one of the best medical professionals I have seen based on customer care, and it is clear that she knows what she’s doing. She puts a real effort in getting to the bottom of things and makes sure that you fully understand what’s going on and the best treatment forward. I specifically chose to see Dr. Rasband a few years after she treated my spouse. I was pleasantly surprised by her consistency in providing the same level of professionalism and care that I witnessed a few years back. I highly recommend.

I had been sick for about a week and after going to urgent care, who tried to get rid of me as fast as possible with no help at all, I received a very different experience at AOO. AOO ENT came highly recommended from a friend. I called them and they got me in within a day. Dr. Agarwal was personable, took her time and did a very thorough job. She didnt sugar coat, which I appreciate. She diagnosed me, ordered me the necessary antibiotics and I already feel better. I am grateful for her help and taking the time to take care of me. Would highly recommend.

I’ve been once but Dr. Schwartz and his MA Spencer were great. The doc was asking many questions and talking about potential things. He was decisive, very personable, and quite charming. I am excited about what we are able to do here.

What to expect at a sleep study appointment
For an in-lab study, you arrive in the evening and sleep in a private room while sensors record breathing, oxygen, heart rhythm and body movement. For a home sleep test, the clinic gives you a portable kit you use in your own bed. Neither test is painful. Results are usually compiled into a physician report within one to two weeks, and the clinic then discusses whether treatment — such as CPAP therapy or an oral appliance — is needed.
Preparation basics: avoid caffeine in the afternoon, skip lotions and hair products, bring comfortable sleepwear, and take your regular medications unless your doctor advises otherwise.

Frequently asked questions about AOO | ENT Specialists of the Rockies
What does AOO | ENT Specialists of the Rockies do?
AOO | ENT Specialists of the Rockies is a sleep medicine clinic in Lone Tree, CO that evaluates and treats sleep disorders such as obstructive sleep apnea, chronic insomnia, restless legs syndrome and narcolepsy. Evaluation usually involves a sleep study, and treatment may include CPAP therapy, an oral appliance, or behavioral therapy depending on the diagnosis.
Do I need a referral to book a sleep study at AOO | ENT Specialists of the Rockies?
Many insurance plans require a referral or prior authorization before covering a sleep study. Requirements vary by insurer and by clinic, so contact AOO | ENT Specialists of the Rockies directly using the phone number on this page and ask what your plan needs.
How much does a sleep study cost at AOO | ENT Specialists of the Rockies?
Sleep study costs vary widely with the type of test, your insurance plan and your deductible. Home sleep tests generally cost less than in-lab studies. Ask the clinic for an itemized estimate and check with your insurer about in-network rates before booking.
Does insurance cover sleep studies and CPAP treatment?
Most US insurers, including Medicare, cover sleep studies and CPAP therapy when they are medically necessary and properly documented. Coverage details — deductibles, co-pays and supply replacement schedules — differ by plan, so verify with your insurer and the clinic.
How long does it take to get sleep study results?
Typically one to two weeks. A sleep physician reviews the recorded data and writes a report, after which the clinic discusses the findings and any recommended treatment with you.
Can I do the sleep study at home?
Possibly. Home sleep apnea tests suit many adults with a high likelihood of obstructive sleep apnea and no major heart or lung conditions. If your symptoms are complex or the home test is negative despite strong symptoms, an in-lab study is usually the next step. The clinic can determine which option fits you.
What should I bring to my appointment at AOO | ENT Specialists of the Rockies?
Comfortable sleepwear, your photo ID and insurance card, a list of current medications, and your own pillow if that helps you sleep. Avoid caffeine after midday and skip lotions or hair products, because sensors attach better to clean skin.
