Medical Benefits Under Michigan Workers' Compensation: What Treatment Is Covered?

Medical benefits are the foundation of every Michigan workers’ comp claim. They sound simple on paper because the rule is broad: reasonable and necessary treatment related to the work injury should be covered for as long as it is needed. In practice, medical benefits are also one of the most disputed areas of workers’ comp.

The basics matter. Workers should know what treatment is covered, how the 28-day doctor selection rule works, and that authorized care should be paid by the workers’ comp insurer. But the more important questions are often practical: What happens when treatment is denied? What does “reasonable and necessary” actually mean? What can you do when the insurer refuses to authorize care your treating doctor recommends?

This page covers both the rules that govern Michigan workers’ comp medical benefits and the disputes that determine whether injured workers actually get the care they need.

What Medical Benefits Actually Cover

Michigan workers’ comp medical benefits are broad. The system is designed to cover the treatment a worker reasonably needs because of a work injury, without an arbitrary cap on what gets paid or how long care continues. As long as the treatment is reasonable, necessary, and connected to the work injury, it should be covered.

What is included. Covered medical care may include the full range of treatment an injured worker needs, including:

No dollar cap and no fixed time limit. Michigan workers’ comp medical benefits are not limited by a fixed dollar amount or automatic end date. A worker who needs long-term care because of a work injury may be entitled to that care for as long as it remains reasonable, necessary, and connected to the injury. This is why medical benefits can represent major long-term value in serious injury cases, and why insurers often dispute ongoing treatment exposure.

The treatment must be connected to the work injury. Workers’ comp medical benefits cover treatment related to the job injury, not unrelated medical conditions. For example, a worker with a compensable back injury may have back treatment covered by workers’ comp, while unrelated treatment for high blood pressure remains separate. The treating physician should make the connection between the recommended care and the work injury clear in the medical records.

The 28-Day Doctor Selection Rule

The 28-day rule is one of the most commonly searched and misunderstood Michigan workers’ comp medical rules. It governs who chooses the treating physician during the early part of the claim, and getting it wrong can affect both treatment and whether medical bills are paid.

How the rule works. For the first 28 days of medical treatment for a work injury, the employer or its insurance company generally has the right to select the treating provider. After that 28-day period, the worker may choose their own physician, but the worker must give written notice to the employer or insurer of the change.

What happens during the first 28 days. The employer often directs the worker to a designated occupational health clinic or approved medical provider. The provider may evaluate the injury, prescribe initial treatment, set work restrictions, and decide whether referrals or diagnostic testing are needed.

Why early treatment shapes the claim. The first 28 days matter more than many workers realize. Decisions made during this period, including what testing is ordered, what restrictions are documented, what referrals are made, and how the injury is described in the medical records, can influence the entire claim. If an employer-selected provider downplays symptoms, releases the worker too quickly, or fails to order appropriate testing, the insurance company may rely on those early records later.

Switching doctors after 28 days. The worker’s right to choose their own physician after 28 days is real, but the process matters. The change should be communicated in writing to both the employer and the insurance company. The notice should identify the new physician and the date the worker is transferring care. Without proper written notice, the insurer may dispute whether the new provider was authorized.

What can go wrong with the 28-day rule. Two common problems arise. First, workers sometimes switch providers during the first 28 days without authorization and later face disputes over whether the treatment will be paid. Second, workers change doctors after 28 days but fail to give proper written notice. Both situations can often be addressed, but they create unnecessary friction. Following the rule carefully from the beginning helps avoid payment disputes and protects the medical record.

What “Reasonable and Necessary” Medical Treatment Means

“Reasonable and necessary” is the standard used to decide whether the workers’ comp insurance company must pay for a particular treatment. The phrase sounds simple, but it is one of the most disputed parts of Michigan workers’ comp medical benefits because insurers use it to challenge care recommended by the treating physician.

Treatment is generally considered reasonable and necessary when it is appropriate for the work injury, supported by medical evidence, and consistent with accepted medical practice. A treating physician’s recommendation matters, but the insurance company does not automatically have to approve every test, referral, procedure, or treatment plan. The insurer can challenge treatment it believes is excessive, unrelated, unsupported, or no longer needed.

Treatment authorization versus payment. These are not the same thing. Authorization means the insurance company approves a treatment before it happens. Payment means the insurer pays the bill after treatment occurs. A treatment may be medically appropriate, but if a worker proceeds with non-emergency care without authorization, the insurer may still fight payment after the fact. Before surgery, advanced diagnostic testing, injections, or specialist care, authorization should be confirmed whenever possible.

How insurers challenge treatment. Insurance companies may use utilization review, peer review, or an Independent Medical Exam to argue that care is not reasonable and necessary. A reviewer may claim additional physical therapy is no longer needed, an injection is not supported, a surgery is excessive, or a specialist referral is unrelated to the work injury. These opinions can become the basis for denying treatment.

What strengthens the treating doctor’s position. The strongest treatment recommendations are specific and well documented. A treating physician should explain the diagnosis, the objective findings, why the treatment is needed, how it relates to the work injury, and what may happen if treatment is delayed or denied. Vague notes and generic recommendations give the insurer more room to argue that the treatment is not reasonable and necessary.

The key point is that “reasonable and necessary” is not just a medical phrase. It is the standard that often decides whether treatment gets approved, delayed, denied, or litigated. That is why the treating physician’s documentation can make such a difference in a medical benefits dispute.

When Medical Treatment Gets Denied

Treatment denials are one of the most common and consequential problems in Michigan workers’ comp medical benefits. Workers who understand how denials typically unfold are in a better position to recognize what is happening and respond before the case stalls.

The treatments most commonly denied. Insurance companies usually do not deny every part of medical care at once. Denials often focus on one specific treatment or recommendation, such as:

How the denial usually arrives. Most treatment denials follow a predictable pattern. The treating physician recommends care. The insurer sends the recommendation to utilization review or peer review. A reviewer concludes the treatment is not reasonable and necessary based on the records. The insurer denies authorization. The worker may learn about the denial through a letter, phone call, adjuster, or medical provider when the office tries to schedule care and discovers no authorization has been issued.

The role of IMEs in treatment denials. Independent Medical Exams often play a major role in treatment denials, especially when the insurer is challenging ongoing care. After an IME, the insurer may argue that the worker has reached maximum medical improvement, that more treatment is no longer reasonable and necessary, or that the condition is not related to the work injury. IME-based denials can be aggressive, but they can also be challenged with strong treating physician support.

Why denials matter financially. A denied surgery may force the worker to delay treatment, fight for authorization, or consider paying out of pocket. A denied course of physical therapy may affect recovery. A denied specialist referral may delay a diagnosis that changes the direction of the claim. Treatment denials are not just medical problems. They can affect work restrictions, disability status, settlement value, and the worker’s ability to recover.

What to Do If Your Treatment Is Denied

A treatment denial is not the end of the road. Workers who respond quickly and strategically often have a better chance of getting the denial reversed. The response should start as soon as the denial arrives, not weeks later.

A denial involving surgery, an IME, or ongoing treatment usually deserves careful review. These disputes can affect not only medical care, but also work restrictions, wage loss benefits, and settlement value.

Medical Bills, Mileage, and Out-of-Pocket Costs

Workers’ comp medical benefits are designed so that injured workers do not pay for authorized treatment out of their own pocket. In practice, this is one of the most commonly misunderstood parts of the system and a source of unnecessary expense for workers who do not understand their rights.

No deductibles, copays, or worker out-of-pocket costs. Authorized workers’ comp medical treatment should be paid directly by the insurer to the medical provider. There are no deductibles, copays, or coinsurance payments like there are with private health insurance. If treatment is authorized and related to the work injury, the worker should not be responsible for paying part of the bill.

What to do when a bill arrives. Bills sometimes arrive at the worker’s home because of billing errors, missing claim information, treatment that was not pre-authorized, treatment the insurer is disputing, or administrative confusion. Do not ignore the bill, but do not assume you are personally responsible either. Contact the medical provider and the claims adjuster to confirm whether the bill was submitted to the correct workers’ comp carrier and whether authorization is being disputed.

When health insurance gets involved. If a workers’ comp claim is initially denied, the worker’s health insurance may pay for treatment in the meantime. This can help the worker get care, but it may create reimbursement issues later. If the workers’ comp claim is eventually approved or settled, the health insurer may assert a subrogation or reimbursement claim for what it paid. Medical bills paid by health insurance during a disputed workers’ comp claim do not always disappear. They may become part of the settlement math later.

Mileage reimbursement. Travel to and from medical appointments connected to the work injury is reimbursable at the applicable mileage rate. This may include visits to treating physicians, physical therapy appointments, specialist consultations, diagnostic testing, IME appointments ordered by the insurer, and other appointments connected to the injury. Workers should keep a log of every appointment with the date, provider, destination, round-trip mileage, and purpose of the visit.

Other reimbursable expenses. Beyond mileage, workers may be entitled to reimbursement for parking fees at medical facilities, tolls when applicable, prescription costs paid out of pocket, and certain other treatment-related expenses. Meals or lodging may be reimbursable in limited situations when treatment requires significant travel. Most insurers require a mileage or expense form with documentation supporting each request.

The pattern that costs workers money. The most common way workers lose money on out-of-pocket costs is failing to track and submit them. A worker who drives to 20 physical therapy appointments and never submits mileage may give up hundreds of dollars in reimbursement. A worker who pays for injury-related prescriptions and never requests reimbursement may lose money the insurer should have paid. Tracking these expenses from the beginning and submitting reimbursement requests regularly is one of the most practical things an injured worker can do.

How Medical Benefits Affect the Value of Your Workers’ Comp Case

Medical benefits are not just about paying for treatment as it happens. They are also one of the biggest drivers of long-term case value and one of the most commonly underestimated factors in settlement negotiations. Understanding how medical benefits affect case value is important before any conversation about settling the claim.

Future medical care is a major settlement variable. When a workers’ comp case is settled through a redemption, the worker may be closing out the right to future medical care paid by the insurer. The settlement amount needs to reflect the value of treatment the worker is likely to need going forward, not just what has already been paid. Workers who settle without an honest assessment of future medical needs may leave significant value on the table.

What future medical care can include. Future medical needs may include treatment that has been recommended but not yet performed, ongoing physical therapy, pain management, future surgery, prescription medication, specialist visits, diagnostic testing, replacement medical equipment, and long-term care or attendant care in serious injury cases.

Why medical exposure motivates the insurer to settle. Insurance companies are often more motivated to settle cases with significant future medical exposure than cases with limited future treatment needs. An open-ended medical obligation is unpredictable and potentially expensive. A worker with permanent restrictions, ongoing treatment needs, and a treating physician who has documented future care requirements may be in a stronger negotiating position than a worker whose records suggest a full recovery with no future treatment anticipated.

The settlement risk of unaddressed medical needs. The most expensive settlement mistake involving medical benefits is settling before the full medical picture is clear. A worker who settles before a recommended surgery is performed may receive a settlement that does not reflect the cost of the surgery, the recovery period, or possible complications. A worker who settles before reaching maximum medical improvement may later discover that the condition was more serious than the settlement assumed.

Why timing matters. The timing of settlement can be as important as the amount. Settling too early, before treatment has stabilized, permanent restrictions are clear, or future medical needs are understood, is one of the most common ways workers undervalue a claim. The right time to settle is generally when the medical picture is clear enough that future needs can be honestly assessed, not simply when the insurer first makes an offer.

How Medical Benefits Affect the Value of Your Workers’ Comp Case

Medical benefits are not just about paying for treatment as it happens. They are also one of the most significant drivers of long-term case value and one of the most commonly underestimated factors in settlement negotiations. Understanding how medical needs affect what the case is worth is essential before any conversation about settling.

The counterintuitive truth about medical exposure. Many workers assume that serious ongoing medical needs make their case harder to settle. The opposite is often true. Insurance companies are often more motivated to settle cases with significant future medical exposure than cases with limited future treatment needs because an open-ended medical obligation is unpredictable and potentially very expensive. A worker with permanent restrictions, ongoing treatment needs, and strong physician documentation is in a stronger negotiating position, not a weaker one.

The timing of when to settle is often as important as the amount. The right time to settle is generally when the medical picture is clear enough that future needs can be honestly assessed, not when the insurer first makes an offer. Once a redemption is approved, the case cannot be reopened, even if medical needs turn out to be far more extensive than anticipated.

When to Get Legal Help

Medical benefits are one of the most disputed areas of Michigan workers’ comp, and getting legal help early can make a practical difference. Treatment denials, IME-based cutoffs, and disputes over future medical care are rarely simple paperwork issues. They affect whether the worker gets the care they need and what the case may ultimately be worth.

Consider speaking with a workers’ comp lawyer if:

At The Clark Law Office, you speak directly with a Michigan workers’ comp lawyer who handles your case personally. You are not passed off to a case manager or treated like just another claim file. Medical benefit disputes often determine whether an injured worker gets the treatment needed to recover or gets pushed toward an early settlement before the full medical picture is known. The earlier the issue is reviewed, the more options are typically available.
