We are contracted with most major insurance companies with the exception of Humana and Medicare Replacement policies.  We will collect your co-payment, coinsurance, and deductible at time of service.  We will file your primary insurance and send you a statement of any balance remaining after your insurance has paid. We do not file secondary insurance with the exception of Medicare. After three consecutive months with no payment, your account may be forwarded to a collection agency.

It is your responsibility to notify us when you have a change in insurance and to obtain a referral from your primary care physician if required by your insurance. We cannot file a claim after the "timely filing" deadline designated by your insurance company.    

If you have no insurance or we are not in network with your insurance, we offer a discount and payment is due in full at the time services are rendered. Once this discount is transacted, your insurance will not be filed after-the-fact.
