Shortly after speaking with Kelsey and making an appointment at the Daly City office I received an email stating that my appointment had been changed to a time that I had said I was unavailable. Several phone messages over several weeks went unanswered. The day before my appointment I called a different number associated with the business and stated the problem. I was put on hold, then told 'she said you can come by after hours.' When I went for the appointment I was met at the door by Kelsey, who handed me a piece of equipment and some papers. I was told by Kelsey that she had someone on the phone and couldn't talk to me at that point, but that she had left her phone number on a post-it stuck to the equipment box if I should have any questions. I felt that the equipment was not working pr

I switched to California Center for sleep disorders because I was getting horrible treatment from another organization (Penninsula sleep center) Because of my terrible experience with penninsula i did not have great expectations when I contacted California center. I was more than pleasantly surprised. The day prior to my appointment I received a call from the nurse technician Natalie. She was amazingly nice and friendly. She walked me through the paperwork with the patience of a saint. She was equally helpful and friendly during my office visit. Dr. Ruddy was Perfect for me. The doctor at Penninsula treated me like just another item on an assembly line and never got my prescription right in 4 months. Dr Ruddy was attentive and intuitive. He asked what I felt were extremely pertinent ques

CCSD and DR KRAM (or is it Dr SCAM?) seem to be a total shady operation. My experience has been HORRIBLE! Avoid this scam operation. Save your time, nerves and money. Billed $5000 and provided absolute no health care, nothing but frustration and headaches. Never got to interact with Dr Kram, or any actual physician. He is NEVER available. Terrible service during sleep study. Double billed me for the at home study and never even provided test results until I opened a formal complaint via my insurance and threatened to take it further. The results (which previously could not be found but then suddenly appeared) revealed they clearly did not provide any actual treatment and proved my case for the over billing. Alas, this still didn’t seem to help resolve the billing error. No one except

My insurance directed me to use this clinic as they are in-network. I've tried calling them for weeks to schedule an appointment, and they do not answer their phone or return my calls. After weeks of calling I was finally able to schedule an appointment. They have now cancelled my appointment twice due to not having equipment at their office. Their customer service is worse than Comcast.

I have never had such a poor experience with a provider - more than a month after the initial appointment and with the expectation that i would schedule (just schedule!) an at home sleep test, still nothing. I called two weeks in and one of the associates mentioned that they were waiting on insurance. I called my insurance and found out they never heard from them. This is your bread and butter. If you are considering this place, go somewhere else.

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.

Frequently asked questions about California Center for Sleep Disorders
What does California Center for Sleep Disorders do?
California Center for Sleep Disorders is a sleep medicine clinic in Daly City, CA 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 California Center for Sleep Disorders?
Many insurance plans require a referral or prior authorization before covering a sleep study. Requirements vary by insurer and by clinic, so contact California Center for Sleep Disorders directly using the phone number on this page and ask what your plan needs.
How much does a sleep study cost at California Center for Sleep Disorders?
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 California Center for Sleep Disorders?
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.
