Insurance and Billing

Insurance issues can be complicated and difficult to understand. Our billing department is helpful and skilled in navigating the "ins and outs" of the insurance system and can be reached at (231) 421-8099 extension 211.

While we do accept all insurances (meaning we will not turn your child away due to what insurance they have), we are not "in network" for every single insurance company, which may affect the amount of money that you as the patient are ultimately responsible for. Please do be mindful of this and do your research with your insurance company prior to choosing a physician!

If we do not participate with your insurer, as a courtesy we will file a claim for you. We expect that you will follow-up with them with any reimbursement issues. Payment is expected at the time of service.

We currently participate with the following insurance companies:

We currently participate with the following Medicaid plans:

  • McLaren
  • Meridian Health Plan
  • “MiChild”
  • Molina

Please bring your current insurance card to each visit so that we may bill properly. 

Financial Policy

To serve our patients in the most efficient and economical manner possible, we must keep our accounts current. For this reason, we ask that all patients pay office copays at the time of service. We accept cash, personal checks, debit cards, health savings account cards, MasterCard, Visa, Discover, American Express, and money orders. A payment plan can be arranged if necessary. We will bill participating insurance companies and Medicaid for you. If we do not participate with your insurer we expect you to pay us directly. As a courtesy we will submit a claim for you when possible, or we will provide you with the necessary forms for reimbursement. We cannot, however, follow-up with them to ensure they have reimbursed you.

If you have any additional questions about our financial policy or specific fees please call our billing specialist between 8:00 a.m. to 5:00 p.m. Monday through Friday at (231) 421-8099 extension 211.

Payment Options

Payment is required at time of service. If you are unable to make payment in full, please ask for more information on payment options.

What our patients say about us

  • "Both of my children were patients of TAPAC, and I can only say Very Good Things about all the services offered. Even when my kids were older, they chose to continue to see Dr. Sara Mulder through college, and I'm so grateful for her care of their physical, mental, and emotional needs during this time of growth. Thank you to all of you who make up the amazing team that is TAPAC."
    Carla W.
  • "I really appreciate the trouble they go through to keep the kids safe during this whole covid thing. Separate docs for healthy kids vs sick. Nice front desk staff. have a doc that specializes in asthma."
  • "We have had nothing but great experiences here at TAPAC. This practice is equipped with very knowledgeable clinical staff and very friendly administrative staff. Our son is comfortable here and loves seeing his primary Dr Koehler but has also had great experiences with Dr Stilwell and Dr Mulder."
