Policy Overview

Our practice firmly believes that a good provider-patient relationship is based upon understanding and open communication.  Our staff is dedicated to answering questions and clarifying any misunderstanding you may have concerning your account.  With the establishment of a provider-patient relationship, we have entered into an agreement to provide your family professional medical services.  The following information is provided to define the financial responsibilities for payment of our professional services.

It is our expectation that the full payment will be made for an office visit at the time of service.  We accept cash, check, VISA, MasterCard, and Discover.


OVERDUE ACCOUNTS:  As stated above, it is our expectation that the full payment for an office visit will be made at the time of service.  For those accounts that are overdue by 60 days, there will be a $30 fee for the overdue balance.  Subsequent late fees of $30 will be applied monthly for each 30 days the account is overdue.  As we recognize that sometimes there are financial hardships, please inform us of any difficulties and our billing manager will be happy to make arrangements with you.

CANCELLATIONS AND NO-SHOW POLICY:  Please allow ample time for cancellation of appointments, 24-hour notice is appreciated for pre-scheduled visits.  For longer evaluations such as for headaches, ADHD, and behavior issues,  48-72 hour notice is preferable.  We understand that extenuating circumstances can arise, please communicate these with us accordingly so that we can make arrangements with you. 

As a courtesy to you, our office staff typically makes reminder calls the day prior to a pre-scheduled appointment.  As this is a courtesy and not an expectation, there may be times when reminder calls cannot be made. Please be sure that our front office staff has your preferred phone number for these calls and that your voicemail is set-up and not full. This ensures that the staff is able to leave a message for the reminder. 

As stated above, please allow at least 24 hours for cancellation of your appointment.  If you are unable to attend a sick visit that was made the same day, please call as soon as possible to cancel.  If ample time is not given, a cancelled appointment may still be counted as a missed appointment.  Appointments that are missed without ample notification will be considered a "No Show" and a missed appointment fee of $30 will be applied to the account.

It is important to contact your health insurance company to be sure your baby is added to your policy.  Unless you do this, most insurances will only cover expenses for your baby for the first 31 days.  After this time, your baby will lose insurance coverage unless you add them to your policy.

We do prefer that your newborn be registered with us prior to delivery to ensure that we accept your insurance.  Expectant moms are encouraged to call the office during their pregnancy so we can confirm availability and coverage.  This will ease the process for you at the hospital after delivery of your special little one.



In this ever-changing heath care environment, insurance coverage can be confusing and difficult to understand.  In an effort to help you better understand your insurance coverage, we have compiled some information regarding deductibles and coordination of benefits. 

Many of you are now finding yourself with high-deductible insurance plans with which you have never dealt before. These plans can have deductibles upwards of $2,500-$5,ooo.  It is important to educate yourself on which type of plan your employer carries, as you are financially responsible for the deductible amount not covered by your insurance. Just like your car insurance, your health plan deductible is an amount that the plan owner (you) is responsible for paying until the amount is met (can be anywhere from $200 to $5,000).  After the deductible is met, your insurance will then pay for a percentage or all of the fees incurred after that, depending on the type of plan.  Most plans have an individual deductible for each family member, as well as a total family deductible. 

All plans are different, there is no "one size fits all" here!  Your employer can pick a "carve-out" plan with very specific coverage (i.e. some plans do not cover medications or office visits until the deductible is met, and other plans do not cover lab testing, images, or procedures until the deductible is met).  Unfortunately, we do not have a way of knowing which type of plan you have, so we highly recommend that you read your coverage manual and Explanation of Benefits (boring, we know, but important to understand!).

What does this mean for you?  All services rendered are submitted first to your insurance company.  When we submit your visit to the insurance company, the portion (in some cases all) of the fee that is not covered by your insurance will then go to a personal balance that you are individually responsible for payment to the office.  We kindly ask that these balances be paid in a timely manner for our professional services. (Please see the "Policies" section for further details).  We aim to continue to provide our patients with high-quality, individualized care in a personalized environment.

Another area that can be confusing is the Coordination of Benefits form.  This form is typically sent to you from your insurance company at the start of the new insurance year (typically January, but for some in July).  This form is essential to fill out and return to your insurance company, as it tells them whether you have a secondary insurance.  Even if you do not have another health insurance plan, this form must be filled out and returned or you will lose coverage!

Our dedicated staff is here to help!  If you have a question about your bill or insurance, please inquire at your visit or call us.  You may reach our billing manager, Chris Wilhelm, at (570) 321-1831.
