Dr. Nicole Yee is absolutely amazing. I was visiting family from out of town when I experienced a miscarriage, and even though I was not an established patient, she took me in without hesitation. From the moment I walked in, she treated me with such kindness, compassion, and genuine care. She made me feel seen, important, and truly cared for during one of the most difficult moments of my life. Dr. Yee was incredibly gentle, patient, and reassuring, and she continued to check in on me to make sure I was okay — something I will never forget. It’s rare to find a doctor who shows that level of empathy and humanity, especially to someone who isn’t even their regular patient. If I lived here, I would choose Dr. Nicole Yee as my OB without question. I am beyond grateful for her and will always

Dr. Victoria Yung is one of the best doctors I have worked with. From the very beginning, she was caring, thorough, and genuinely invested in my health. She guided me through every step of my diagnosis and treatment, always making sure I understood what was happening and what the next steps would be. Her responsiveness, professionalism, and kindness gave me a lot of confidence during a stressful time. Thanks to her care, my H. pylori infection was successfully treated, and I am incredibly grateful for her help. I highly recommend Dr. Yung and her team.

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 BASS Medical Group
What does BASS Medical Group do?
BASS Medical Group is a sleep medicine clinic in Walnut Creek, 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 BASS Medical Group?
Many insurance plans require a referral or prior authorization before covering a sleep study. Requirements vary by insurer and by clinic, so contact BASS Medical Group directly using the phone number on this page and ask what your plan needs.
How much does a sleep study cost at BASS Medical Group?
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 BASS Medical Group?
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.
