Michigan Collateral Source Rule: How MCL 600.6303 Cuts Awards

अटॉर्नी मैनी चहल द्वारा · जून 2026 को अपडेट किया गया · पढ़ने का समय: ~8 मिनट

A jury can award an injury victim full economic damages and the victim can still take home less than the verdict says. The reason is the collateral source rule. In Michigan, MCL 600.6303 lets a court reduce a personal injury award by amounts that insurance or other sources already paid for the same loss. The goal is to prevent double recovery, but the statute is full of exclusions that decide whether a given payment actually cuts the award. Knowing which payments count, and which do not, is the difference between keeping a verdict intact and watching a chunk of it disappear after trial.

What the Collateral Source Rule Does

At common law, a defendant could not tell the jury that a plaintiff’s medical bills or lost wages had already been covered by insurance. The wrongdoer was not allowed to benefit from the victim’s foresight in buying coverage. Michigan changed that by statute. Under MCL 600.6303, after a jury returns a verdict for the plaintiff and before the judgment is entered, the defendant may show the court that some of the plaintiff’s economic loss was paid or is payable by a collateral source. The court then reduces the award by that amount.

Two limits matter immediately. First, the reduction applies only to economic damages, things like medical expenses, lost earnings, and other out-of-pocket loss. It does not touch noneconomic damages such as pain and suffering. Second, the process happens after the verdict, decided by the judge, not the jury. The jury hears the full loss and awards it. The reduction is a separate, post-trial step.

Statutory basis: MCL 600.6303 directs that in a personal injury action seeking medical, rehabilitation, lost-earnings, or other economic damages, evidence that the expense or loss was paid or is payable by a collateral source is admissible to the court after a verdict for the plaintiff and before judgment. The court then reduces the economic-damages portion of the award accordingly.

What Counts as a “Collateral Source”

A collateral source is generally a payment the plaintiff received for the same loss from somewhere other than the defendant. Typical examples include health insurance payments and similar benefits. But MCL 600.6303 carves out important exceptions, and those exclusions often decide the outcome:

  • Life insurance is excluded. Life insurance benefits are not a collateral source and do not reduce the award.
  • Benefits subject to a lien or subrogation are excluded. Under MCL 600.6303(4), a payment is not a collateral source if the payer is entitled by contract to a lien against, or subrogation from, the plaintiff’s recovery. If a health plan must be repaid out of the settlement, that payment cannot also be used to shrink the award.
  • The plaintiff’s own premiums are credited back. The court adds back the amount the plaintiff paid in premiums to secure the collateral source, so the victim is not penalized for having bought the coverage.

The lien-and-subrogation carve-out is the one that surprises people. It exists to prevent a double reduction. If a health insurer has already paid a victim’s medical bills and has a contractual right to be repaid from the recovery, the victim will have to repay that money out of the verdict. Letting the defendant also subtract it would punish the victim twice. Our guide to medical liens and subrogation on injury settlements explains how those repayment rights work in practice.

The Post-Verdict Notice Trap

The collateral source process runs on a tight clock that catches the unwary. After a verdict for the plaintiff, the plaintiff’s attorney must promptly notify any contractual lienholders, by registered mail, of the verdict. A lienholder then has a short window to assert its subrogation right. If the lienholder does not act within the statutory period after receiving notice, it can lose the right of subrogation entirely. Handled correctly, this sequence protects the client. Missed, it can forfeit reductions or rights that should have been preserved. These deadlines run independently of the general limitations periods covered in our guide to the Michigan personal injury statute of limitations.

How No-Fault Benefits Fit In

Auto cases add a wrinkle. Michigan’s no-fault system already keeps personal protection insurance (PIP) benefits out of the third-party tort case through its own coordination and reimbursement provisions, separate from MCL 600.6303. The practical result is that PIP medical and wage-loss benefits are handled under the no-fault act, while the collateral source rule governs other economic damages in the tort case. After the 2019 reforms, when a victim’s losses exceed a chosen PIP coverage level, the uncovered economic loss may be pursued in tort, and recoveries that are not PIP benefits are not treated as no-fault collateral sources. The interaction is technical, and the order in which PIP, liens, and the 6303 reduction are applied can change the net recovery. For the wage-loss piece, see our guide to no-fault wage-loss benefits and the statutory cap.

Practical point: Because PIP benefits travel on the no-fault track and lien-backed payments are excluded from the collateral source definition, the amount a defendant can actually subtract under MCL 600.6303 is often far smaller than the gross medical bills suggest. Each payment must be sorted into the right category before any reduction is calculated.

Why This Decides Take-Home Recovery

The collateral source rule is easy to overlook until the verdict arrives, and then it controls what the client actually keeps. A plaintiff who treats every insurance payment as a guaranteed deduction may undervalue a case; a defendant who assumes all medical payments reduce the award may overpay. The correct figure depends on close work after trial: identifying every payer, separating lien-backed and subrogated benefits from true collateral sources, crediting premiums, and meeting the notice deadlines. Building that record before trial, not after, is what keeps a verdict from quietly shrinking.

अक्सर पूछे जाने वाले प्रश्न

What is the collateral source rule in Michigan?

It is a statutory rule, MCL 600.6303, that lets a court reduce a personal injury award by economic-loss amounts already paid or payable by a collateral source such as health insurance. The reduction happens after the verdict and applies only to economic damages, not to pain and suffering.

Does every insurance payment reduce my award?

No. Payments subject to a contractual lien or subrogation right are excluded under MCL 600.6303(4), and life insurance benefits are excluded entirely. The court also credits back the premiums you paid for the coverage. Only true collateral sources reduce the award.

Are pain-and-suffering damages reduced?

No. The collateral source rule applies only to economic damages like medical bills and lost wages. Noneconomic damages, including pain and suffering, are not reduced under MCL 600.6303.

What happens with my health insurer’s lien?

If your health plan has a contractual right to be repaid from your recovery, those payments are not a collateral source and do not reduce the award, but you will generally have to repay the plan from the proceeds. There are also short post-verdict notice deadlines for lienholders, so the sequence must be handled carefully.

How does this work in a car accident case?

No-fault PIP benefits are handled under the no-fault act’s own coordination rules, separate from MCL 600.6303. Economic losses pursued in the third-party tort case are where the collateral source rule typically operates. The order of PIP, liens, and the reduction can change your net recovery, so the calculation should be reviewed by counsel.

Do I need a lawyer to deal with collateral source reductions?

It is strongly advisable. The reduction is calculated after trial, depends on correctly categorizing every payment, and involves strict notice deadlines for lienholders. Mistakes can cost a plaintiff money that should have stayed with the verdict.
