Michigan No-Fault Utilization Review: What Injured Patients Must Know

If your auto insurer is scrutinizing or cutting off your medical care after a Michigan crash, you have likely encountered utilization review — and understanding how it works can mean the difference between getting the treatment you need and watching your recovery stall while fighting a faceless bureaucracy.

Michigan’s no-fault system is designed to pay for accident-related medical expenses without limits on serious injuries, but the 2019 No-Fault Reform Act introduced a formal utilization review (UR) process that gives insurers a new tool to challenge your care. Two recent appellate decisions have clarified your rights, and proposed legislation in 2026 may tip the balance further. Here is what every injured Michigan motorist needs to know.

What Is Utilization Review Under Michigan’s No-Fault Act?

Utilization review is the process by which a no-fault insurer evaluates whether the medical treatment you are receiving — surgeries, physical therapy, pain management, diagnostic imaging, home attendant care — is medically necessary and priced within allowable fee schedules.

Under MCL 500.3157a, enacted as part of the 2019 reforms, insurers are permitted to subject claimed Personal Injury Protection (PIP) benefits to utilization review. The statute requires that UR be conducted by appropriately credentialed medical reviewers using medically accepted standards. The insurer must notify the treating provider and the insured of the determination, including the specific clinical basis for any denial or reduction.

On paper, the system is supposed to weed out unnecessary or inflated billing. In practice, injured claimants often find that UR is used as a cost-containment strategy — denying legitimate care that their treating physicians have recommended.

The 2019 Reforms Created This Framework — and Its Pitfalls

Before the 2019 No-Fault Reform Act (Public Act 21 of 2019), Michigan’s PIP system provided unlimited medical benefits for reasonably necessary treatment. The reforms imposed tiered coverage limits (ranging from $50,000 to unlimited, depending on the policy elected), slashed provider reimbursement rates through mandatory fee schedules under MCL 500.3157, and authorized insurers to contest care through formal UR procedures.

The combination has proven painful for seriously injured claimants. Providers are reimbursed at reduced rates, creating gaps in the provider network willing to treat no-fault patients. UR denials add another layer — even when a physician says you need a procedure, the insurer’s reviewer may overrule that clinical judgment. If you selected a policy with a $250,000 or $500,000 PIP cap rather than unlimited coverage, a prolonged UR battle can accelerate the exhaustion of your benefits.

Two Landmark Court Decisions Protect Your Rights

True Care Physical Therapy v. Auto Club Group (2023)

In True Care Physical Therapy, PLLC v. Auto Club Group Insurance Co., the Michigan Court of Appeals addressed a critical question: must a health care provider exhaust the administrative appeal process established under MCL 500.3157a(5) before filing a lawsuit against the insurer?

The insurer argued yes — that providers (and by extension injured claimants) had to go through DIFS (the Michigan Department of Insurance and Financial Services) before they could sue. The Court of Appeals said no. The plain language of MCL 500.3157a provides DIFS with a non-exclusive grant of jurisdiction, and the administrative rules make the appeal procedure voluntary, not mandatory.

This is significant because administrative appeals are often slow and insurer-friendly. The ruling preserves your right — and your provider’s right — to go straight to the circuit court when an insurer wrongfully denies or reduces care.

Pro-Line Physical Therapy v. Meemic Insurance (2024)

In Pro-Line Physical Therapy v. Meemic Insurance Co. (Mich. Ct. App., 2024), the Court of Appeals reinforced the True Care holding. When Meemic discontinued PIP benefits following a UR determination, the provider sued in circuit court without first appealing to DIFS. Meemic moved to dismiss for lack of subject-matter jurisdiction, claiming the provider had to exhaust the administrative remedy first. The Court of Appeals rejected that argument again, confirming that the DIFS appeal path is an option, not a prerequisite.

Together, these two decisions mean that if your insurer cuts off your no-fault medical benefits after a utilization review, you are not trapped in a slow administrative process. You — or your attorney — can challenge that denial in circuit court.

Pending Legislation: Senate Bill 547 (2025–2026)

The Michigan Legislature has been actively revisiting UR procedures. Senate Bill 547, introduced in the 2025–2026 legislative session, would require insurers to comply with DIFS determinations in utilization review disputes. If enacted, this would give the administrative appeal process more teeth — meaning insurers could not simply ignore a DIFS ruling in a provider’s favor and continue denying benefits.

The bill also addresses transparency in the UR process, targeting situations where insurer-retained reviewers issue blanket denials without adequate engagement with the treating provider’s records. The legislation has not yet been signed into law, and its path through the Senate and House will be influenced by multiple stakeholders. Injured claimants and advocates should monitor its progress.

How Utilization Review Affects Your Claim in Practice

What triggers a UR review?

Insurers may initiate UR at any point after treatment begins. Common triggers include: high-cost procedures (surgery, inpatient rehabilitation, neurosurgery, spinal interventions), ongoing attendant care claims, and treatment extending beyond typical recovery timelines. There is no statutory cap on the number of UR reviews an insurer may request.

What happens when treatment is denied?

When an insurer issues a UR denial, it must provide written notice stating the clinical basis under MCL 500.3157a. Your treating provider has the right to request a peer-to-peer discussion with the UR reviewer. If the denial stands, you have several options:

• Request a DIFS administrative review (voluntary, no filing fee, but outcomes are advisory under current law).
• File suit in circuit court — as confirmed by True Care and Pro-Line, you do not have to exhaust the administrative route first.
• Seek an independent medical examination (IME) from a physician of your choice to counter the insurer’s reviewer.

Time limits matter

Your right to sue for unpaid PIP benefits is governed by MCL 500.3145, which imposes a one-year back-rule — meaning you can only recover benefits for expenses incurred within one year before filing suit. If an insurer denies treatment and you wait too long to act, you may permanently lose the right to recover those expenses. Under MCL 600.5805, the general statute of limitations for personal injury actions in Michigan is three years, but the PIP-specific one-year back-rule under MCL 500.3145 is the operative limit for most no-fault medical benefit disputes.

Do not wait. If your benefits have been cut, consult a Michigan personal injury attorney promptly. For a broader discussion of filing deadlines, see our Knowledge Base article on Michigan Statute of Limitations: When You Must File Your Personal Injury Lawsuit.

What You Can Do Right Now

If you are an injured Michigan motorist whose no-fault insurer has denied, reduced, or delayed payment for medical treatment following a utilization review, take these steps:

1. Get the written denial in hand. The insurer is required by MCL 500.3157a to provide written notice with the specific clinical rationale. Demand it in writing if you have not received it.
2. Keep seeing your doctor. A UR denial does not mean your condition is not serious or your treatment is not necessary — it means the insurer’s reviewer disagrees. Your treating physician’s opinion matters. Continue care as recommended and document everything.
3. Have your provider request a peer-to-peer review. A direct conversation between the treating physician and the UR reviewer sometimes reverses a denial, particularly where the reviewer may not have fully engaged with all clinical records.
4. Preserve all records. Keep copies of every explanation of benefits, denial letter, treatment record, and correspondence. These are essential evidence in any subsequent legal action.
5. Consult a personal injury attorney. UR disputes involving significant treatment costs are not straightforward and involve complex interplay between PIP law, fee schedules, and evidentiary requirements. Michigan personal injury attorneys who handle no-fault cases can evaluate your claim, engage your insurer, and — if necessary — file suit in circuit court without first exhausting the administrative process.

Frequently Asked Questions

Can my insurer stop paying for my treatment just because a reviewer said it’s unnecessary?

Yes — but that determination can be challenged. The insurer’s UR reviewer is not your treating physician, and courts recognize that treating physicians who actually examine patients are often in the best position to determine medical necessity. A denial is not the end of the road; it is the beginning of a dispute that can be resolved in your favor with the right legal and medical support.

Do I have to appeal to DIFS before I can sue?

No. Under True Care Physical Therapy v. Auto Club Group (2023, Mich. Ct. App.) and Pro-Line Physical Therapy v. Meemic (2024, Mich. Ct. App.), the administrative appeal process is voluntary. You may proceed directly to circuit court.

What if my PIP coverage limit is running low because of these disputes?

This is a real concern for claimants with $250,000 or $500,000 PIP caps who have suffered serious injuries. If you selected limited coverage, every month of disputed treatment counts against your cap. See our article on What to Do When Your Michigan PIP Benefits Run Out for guidance on cascading coverage and remaining options.

Is Senate Bill 547 law yet?

As of May 2026, SB 547 has not been enacted. It remains pending in the Michigan Legislature. The law as it currently stands — as interpreted by the Court of Appeals — does not require insurers to comply with DIFS UR determinations. That is precisely what SB 547 seeks to change.
