How is CareCredit different from my other bank cards?

CareCredit extends special financing offers that you can't get when using your Visa or MasterCard to pay for health, beauty and wellness care at enrolled providers. With shorter term financing options of 6, 12, 18 or 24 months no interest is charged on purchases of $200 or more when you make the minimum monthly payments and pay the full amount due by the end of the promotional period. If you do not, interest is charged from the original purchase date**.

CareCredit also extends longer term healthcare financing for 24, 36, 48 or 60-month periods with a Reduced APR and Fixed Monthly Payments Required until paid in Full. Purchases of $2,500 or more qualify for the 60-month offer with a 16.9% APR (24, 36 and 48 financing terms are for purchases of $1,000 or more with a 14.9% APR**).

Is CareCredit a medical insurance policy?

No. CareCredit is a healthcare credit card and it does not replace medical insurance policies that you might have. It is intended to help you pay for out-of-pocket expenses that are not covered by your health plan.

I'm not sure I want another credit card. Why do I want CareCredit?

CareCredit helps you pay for out-of-pocket healthcare expenses for you, your family, and even your pets! Once you are approved, you can use it again and again* to help you manage health, wellness and beauty costs not covered by insurance.

When are allergies serious enough to seek medical help?

Allergies are extremely common and affect millions of Americans.  Symptoms range from a stuffy nose and occasional sneeze to severe allergic reactions.  Allergies are also a common trigger for asthma attacks.  Patients with asthma experience chest tightness, shortness of breath, wheezing and coughing.  Common substances that cause allergic symptoms include pollen (grass, tree and weeds), mold spores, dust mites, feathers and animal dander.  If allergies are causing you discomfort or impairing your ability to work, play or enjoy life, come visit us to see how we can help.

Why doesn't everyone have allergies?

Allergies are caused by the immune system reacting to substances (or allergens) that would typically not trigger a reaction.  Allergies result from environmental factors and genetic predisposition.  If one parent is allergic, the risk of allergies in a child is 30 to 40 percent.  If both parents are allergic, there is a 50 to 70 percent chance of a child developing allergies.  The board certified allergist's goal is to help patients prevent symptoms by managing their allergies and asthma so they can lead healthy, normal lives.  The strong emphasis placed on individualized patient care has been part of the clinic's philosophy of practice for over 75 years.
