An Update on Insurance & Our New Concierge Service

At Grand River Rehabilitation LLC, we are committed to providing high-level, individualized care. To ensure we can continue meeting our standards of excellence, we are making some adjustments to our insurance participation and introducing a new way to work with us in the new year.

Insurance Changes (Effective Dec 31, 2025)

Starting at the end of this month, Grand River Rehabilitation LLC will no longer participate with the following networks for our adult patients:

  • ASR
  • Blue Care Network
  • HAP (Health Alliance Plan)
  • McLaren Health Plan
  • Medicaid
  • UHC

Important: No Change for Pediatric Patients

We understand the specialized needs of our youngest patients. We will continue to accept all currently contracted insurances for pediatric patients at this time. There will be no disruption to their coverage or care within Grand River Rehabilitation LLC.


Also, to our patients who have one of the above plans, but only as your secondary coverage: there will be no change to your care, either.

Introducing: Grand River Concierge LLC

Many of our adult patients have asked if they can simply pay "out-of-pocket" to remain in our care. Due to the legal complexities of insurance contracts, we cannot accept private pay under our existing entity.

In response to your requests, we are currently forming Grand River Concierge LLC, launching in January/February 2026. This sister practice is designed to be a seamless way for you to continue your treatment with the provider you trust.

  • Fee-for-Service: Payments are made at the time of service at a competitive rate.
  • Out-of-Network Reimbursement: We will provide you with a Superbill at every visit. You can submit this to your insurance provider to seek reimbursement using your out-of-network benefits.
  • Same Location, Same Care: This is simply a billing mechanism to allow us to see you outside of restrictive insurance contracts.

Next Steps

We are working diligently to finalize the billing and legal infrastructure for this transition. If your insurance is changing at the end of the month and you would like to continue your care through Grand River Concierge LLC, please let our front desk know.

Grand River Concierge LLC: Frequently Asked Questions

Please call us at 616.780.2324 if you cannot find an answer to your question.

Insurance contracts often prevent providers from accepting cash from members for covered services under the same Tax ID. By creating Grand River Concierge LLC, we create a legal pathway to provide you with the care you want at a transparent price.


No. Everything stays exactly the same. You will use the same phone number, see us in the same office, and work with the same staff you already know and trust. Grand River Concierge LLC is simply the administrative way we process your visits.


We are working hard to make this transition as invisible as possible. Our goal is to maintain your current patient portal and chart so that your medical history remains seamless and accessible to you. We will update you as soon as the technical integration is finalized.


Insurance contracts are complex. Most "preferred provider" agreements legally prohibit a practice from accepting cash from a patient if that practice also has a contract with the patient's insurance company. By creating a separate entity, we can legally and ethically offer you a way to pay for your care directly without violating those contracts.


At the end of your visit, we will provide you with a standardized document called a Superbill. It contains all the necessary diagnosis and procedure codes. You simply mail or upload this to your insurance company. Depending on your "out-of-network" benefits, they may reimburse you directly for a portion of the cost.


To keep things fair and transparent, our fee-for-service rates are modeled after our most competitive insurance payer rates. Please contact our office for a specific fee schedule.


Not at all. For the time being, we are continuing to accept all current insurances for our pediatric patients through Grand River Rehabilitation LLC. Your care and billing process will remain exactly as it is now.


We are currently finalizing the legal and billing infrastructure and expect to go live in January or February 2026. If you have an immediate need or want to ensure you are on our first wave of appointments, please reach out to us today to join our priority list.
