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

Please help us welcome Courtney to our practice! We have known her for years as an excellent nurse case manager. Courtney recently completed her nurse practitioner training and certification. We are delighted that she is joining us!

Dr. Rush has for the fourth year in a row been chosen as a Top Doctor by Grand Rapids Magazine. Peer physicians nominate and vote for these doctors, making this recognition truly appreciated! The listing is in GR Magazine's May issue.

We especially appreciate our patients who consistently arrive on time and have their paperwork completed. To ensure fairness for all, we've implemented a rescheduling fee of $200 for new patients and $100 for established patients who cancel late or miss appointments without notice.
RENLY was featured in PAWS With a Cause's Summer 2024 Newsletter. She's the canine social worker superhero (along with her sidekick, Captain America)!

Dr. Rush has for the third year in a row been chosen as a Top Doctor by Grand Rapids Magazine in both Pain Medicine and Physical Medicine & Rehabilitation. Physicians are nominated by and voted upon by their peers, so this is truly appreciated! The listing will be in GR Magazine's May issue.

We are very happy to announce that pediatric physiatrist Lisa Voss, DO is now at Grand River Rehabilitation full-time. Dr. Voss has been extraordinarily popular with patients at Mary Free Bed Rehabilitation Hospital for the last seven years.
Dr. Voss is board-certified in Physical Medicine & Rehabilitation and in Pediatric Rehabilitation Medicine. She's also trained in Advanced Assessment of General Movements, an evidence-based method for diagnosing disorders such as cerebral palsy in young infants.

Dr. Rush has again been chosen as a Top Doctor by Grand Rapids Magazine in Physical Medicine & Rehabilitation. Physicians are nominated by and voted upon by their peers, so this is once again greatly appreciated!

We just learned that in 2022 Dr. Rush was chosen as a Top Doctor by Grand Rapids Magazine in two categories: Pain Medicine and Physical Medicine & Rehabilitation. Physicians are nominated by and voted upon by their peers, so this is greatly appreciated. Thank you!
Two ways: Quality and Access.
Dr. Rush and Dr. Voss have consistently been rated as the top pediatric physiatrists in West Michigan.
There should be no barriers to the care you or your child deserve. We do not require physician referrals*—we are happy to accept referrals from any licensed healthcare professional.
*Unless your insurance requires it, of course.
