Question about your bill

What billing or insurance information will I receive?

When you come into our office for the first time, bring a photo ID and your insurance cards.  We will check on your eligibility when you are registered as a new patient and will be verified before your subsequent appointments.

How long will it take to get things settled with the insurance company?

According to CA state law, insurance companies have 45 to 60 days to pay a claim.  Sometimes the processors need additional information which may delay the payment.

Why am I getting bills from physicians?

Many insurance plans have out of pocket expenses due to co-payments, deductibles and co-insurance percentages.  We post information from the explanation of benefits from your insurance company.  If payment is due to your responsibility you will receive a statement and request for payment from Chestnut Medical Group.

I received a notice that my insurance company has paid on my bill - but I can't understand how they calculated their payment amount. Do you know?

Chestnut Medical Group posts information given to us from your claim explanation of benefits but we do not know the plan information on each individual's policy.   We are looking at the same explanation that is mailed to you.

You receive a booklet or letter explaining your benefits when you or your employer enrolls you in a health insurance plan.  If you have questions, you should call the member services phone number listed on your card or talk to the human resources coordinator where you work.

The Best Care

Welcome to Chestnut Medical Group.  As a new patient you will call in for your first appointment.  When you do, the new patient coordinator will take down your information and verify eligibility with your insurance company.  A call will be returned to you to schedule with your doctor.  

On your first visit in the office you will have paperwork to fill out.  Please allow an additional 15 minutes to fill this out.  Your doctor will need to know what medications your are taking so have a list or your bottles handy for review.  You can find these forms on the Home Page to print and fill out ahead of time.

The medical assistant will obtain your height, weight, blood pressure and a brief history before the doctor comes in to the room.  If you have forms to fill out such as disability, pre-employment or any other request there is a $15 charge to complete them.  

Referrals to specialists typically take two weeks to process and are often determined by the pre-authorization process of your health plan as well as the availability of the specialist's office schedule.
