Cancellation Policy

We do have a 24-hour cancellation policy. Please be considerate of other patients and our staff; if you have to cancel your appointment, please call our office at least 24 hours in advance of your appointment.

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.

Out-of-Network, Medicare, and Medicaid

We do not participate in any Medicaid plans and we have opted out of Medicare. If you receive benefits from an out-of-network provider, you are responsible for all the charges of your visit.

Contact us if you have any questions regarding insurance coverage, billing, or our payment procedures.
