My experience with Cynthia Mathieu, APN was wonderful. As a new patient, I truly look forward to future visits. Dr. Mathieu took the time to listen to all of my concerns and immediately addressed everything that needed to be done. The staff and nurses were also wonderful and made me feel very comfortable from the moment I arrived. I feel confident that I made the right choice in switching my PCP to Dr. Mathieu. I’m grateful to be on this journey toward better health with such a caring and attentive provider.

Upon arrival, I observed the front desk clerk engaged in a personal conversation with a patient, and I was not acknowledged until I had to speak loudly to inquire about signing in, as I was using crutches. My son, who is disabled and has limited ability to advocate for himself or comprehend simple tasks following a massive seizure in December 2025 was eventually called to provide his information and complete paperwork after a 25-minute wait. As I walked away from the counter, another clerk made an inappropriate comment about me, prompting a response from the first clerk.

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 The Heart Center of the Oranges
What does The Heart Center of the Oranges do?
The Heart Center of the Oranges is a sleep medicine clinic in Maplewood, NJ 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 The Heart Center of the Oranges?
Many insurance plans require a referral or prior authorization before covering a sleep study. Requirements vary by insurer and by clinic, so contact The Heart Center of the Oranges directly using the phone number on this page and ask what your plan needs.
How much does a sleep study cost at The Heart Center of the Oranges?
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 The Heart Center of the Oranges?
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.
