Billing & Insurance

Office Visits:

Your co-payment and any remaining deductible are due at the time of your appointment. We accept cash, personal check, Visa and MasterCard. If you have any questions regarding the amount of your co-payment please contact your insurance company. Additional billing inquiries may be directed to our billing staff by phone at 301-654-1575 (option 5).

Sleep Laboratory Studies:

After you schedule a sleep study our billing office will contact your insurance company to determine whether you are covered for the requested study and to request an estimate of your out-of-pocket responsibility for the study. Insurance companies will generally indicate if the study is approvable but will not ever guarantee coverage in advance. They always reserve the right to deny coverage. We make every attempt to clarify your benefits in advance so that there are no surprises. Your co-payment and any remaining deductible (as specified by your insurance company) are due at the time of your study and can be paid for with cash, personal check, Visa, MasterCard, and Discover.  We do not accept American Express.

Your bill is due upon receipt of statement. If you are unable to pay your bill in full at the time of your visit we will customize a payment plan for you. Please be sure to contact our Billing Office prior to your visit to work out details.

Please be sure to bring your referral to your appointment if one is required by your insurance company. If you do not have a referral with you at the time of service you will be asked to sign an “Acknowledgement of Responsibility” form and will be charged in full for services rendered. If you are able to provide a properly dated, valid referral within two working days, fees will be refunded to you minus any co-payment assessed by your insurance carrier.


Late Cancellation Fees:

Please be courteous to fellow patients awaiting appointments and sleep studies and provide us with at least 24 hours notice if you are unable to make your appointment. If your study or appointment is scheduled before the next working day then please call 301-654-1575, follow the instructions to leave an emergency message (press 8) and leave a voice message. Late cancellation fees will be assessed if you fail to comply with this policy. Please note that late cancellation fees are YOUR responsibility and cannot be billed to your insurance company. There is a $375 late cancellation fee for sleep studies cancelled with less then 24 hours notice. To reach Dr. Emsellem on nights or weekends, please dial (301) 654-1575, press 8 and leave your name and phone number and she will return your call.

There is a $375 late cancellation fee for new patient consultations that are cancelled with less than 24 hours notice. Patients will not be rescheduled for a new patient visit unless this fee is paid in advance.

There is an $50 late cancellation fee for follow-up visits cancelled with less than 24 hours notice.
