Frequently Asked Questions
Here are some of the most common questions that patients ask regarding sleep issues. If you have additional inquiries or wish to arrange an appointment, we would be delighted to hear from you.
What insurance do you accept, and do I need a referral?
We accept most insurance, including Medicare and Medicaid. Most plans that require you to pick a Primary Care Physician will require that physician to issue a referral number to us.
How much does my insurance cover?
Coverage varies from policy to policy. Most major insurance companies will pay 80% of reasonable and customary if we are considered “in Network”. For the most accurate information you may call the customer service number on your card to check the coverage for your policy.
What happens on my first visit?
Generally, your first visit will be an office visit. This appointment takes about one hour. After reviewing your medical information, sleep history, and a brief exam we will determine if you need a sleep study(s). The Doctor or Nurse will explain which study(s) you need and have them scheduled before you leave the office. Read your appointment letter carefully to find out if your first visit is a daytime office visit or if it is a sleep study visit at night only. See our section on “What to Expect” for more info on sleep studies.
Why do I need two overnight studies?
The most accurate way to do sleep testing is to have one full night of diagnostic testing, followed by one full night of treatment if you have sleep apnea. The most common treatment for apnea is CPAP (pronounced see-pap). See our section on sleep apnea and treatment for more information. On occasion, the technicians may be able to complete part of both tests in one night, called a split night study.
