Insurance and Making Payments

The Allergy and Asthma Center accepts several different payments from several health care insurance providers. If you have a deductible, coinsurance, and/or copay as part of your insurance policy, please be prepared to pay it at the time of your office visit.

It is the PATIENT'S RESPONSIBILITY to verify insurance benefits and to verify that we are an in-network provider.

The Allergy and Asthma Center uses an outside billing company (Physicians Billing Services, Burke, Virginia) for all patient billing issues.

Cancellation Policy

Our practice abides by a 24-hour business-day cancellation policy. If your appointment is not canceled within 24 hours of your scheduled appointment, you will be charged a $50 cancellation fee for your visit. If it is a medication or food challenge, you will be charged a $100 cancellation fee. Cancellations must be done during business hours on weekdays only. Voice mails left over weekends or holidays are not acceptable as cancellation notifications.


Financial Policy of Allergy and Asthma Center (Anita N. Wasan, MD, PLC)

When our practice sees you as a patient, it is our policy to bill your insurance company for both the office visit and any procedures administered. Your insurance company reimburses us according to the contracted rates. If you owe more than your copay, depending on your insurance policy, you may owe an additional fee for certain procedures due to your deductible or co-insurance.

If the insurance company tells us to bill you any expenses out of your deductible or co-insurance, you will receive a statement from us. These statements are nonnegotiable and are due within 30 days of receiving the notification.


Referral Policy

If you are a member of any HMO plans, it is your responsibility to have a current referral at the time of your appointment. If you have not obtained a referral, it is expired, or you did not bring it, you are responsible for all charges.


Prior to an Appointment

We do not guarantee participation, benefits, or coverage with insurance companies. It is the patient’s/parent’s responsibility to confirm our participation and benefits with their insurance company. Please call your insurance company to confirm our participation and your benefits prior to your appointment.
