Ohio Collateral Source Rule: What ORC 2315.20 Allows at Trial

The Ohio collateral source rule was partially abolished by Ohio Revised Code 2315.20, which lets a defendant in most tort cases tell the jury that the injured plaintiff already received payments from insurance or another outside source. The common-law rule used to bar that evidence completely. It still does in a few important categories, including medical malpractice and any benefit backed by a subrogation right, so whether the jury hears about your health insurance depends entirely on the type of case and the type of coverage.¹

What the Statute Lets the Defendant Do

Under Division (A) of ORC 2315.20, a defendant in a tort action may introduce evidence of any amount paid to the plaintiff as a benefit resulting from the same injury that is the subject of the lawsuit. If a negligent driver hit you and your health plan covered $40,000 in surgery, the defendant can potentially put that $40,000 payment in front of the jury. The idea is to give jurors a fuller picture of your financial position when they decide what a fair verdict looks like.¹

The statute does not require the jury to subtract those payments dollar-for-dollar from the award. Jurors hear the evidence and weigh it however they see fit. They might decide the collateral payments say nothing about what the defendant owes, or they might reduce the verdict. That discretion separates Ohio from states with mandatory post-verdict offsets.

Benefits the Jury Does Not Hear About

The exceptions do most of the real work. ORC 2315.20(A) blocks a defendant from introducing collateral benefit evidence in three categories:¹

Payments from a source that holds a mandatory federal, contractual, or statutory right of subrogation. Most private health insurers, Medicare, Medicaid, and workers’ compensation carriers have subrogation clauses, so their payments are typically shielded from the jury.
Life insurance proceeds paid to the plaintiff.
Disability payments received by the plaintiff.

One narrow carve-out applies to the life insurance and disability categories. If the plaintiff’s employer paid for that policy and the same employer is a defendant in the lawsuit, the evidence comes in. Outside that specific setup, those payments stay invisible to jurors.

The subrogation exception is the one that fires most often. Because most health insurance policies include a right to recover payments out of any tort settlement or judgment, the defendant frequently cannot mention those benefits at all. In practical terms, Division (A) mainly opens the door to benefits from sources without subrogation rights, such as certain gratuitous or charitable payments and plans that happen to lack subrogation language.

Your Right to Show What You Paid for the Coverage

Division (B) gives you a counter-move. Once the defendant introduces evidence of a collateral benefit, you may introduce evidence of any premiums, contributions, or costs you paid to secure that benefit. If an employer-sponsored health plan covered your treatment and the defendant tells the jury about it, you can show the jury how much you paid in monthly premiums over the years to keep that coverage in place.¹

That matters because it answers the implicit suggestion that you got a free ride. A juror who hears you paid $6,000 a year in premiums for a decade is less likely to penalize you for having coverage when the injury occurred.

What the Insurer Gives Up When the Evidence Comes In

Division (C) attaches a serious consequence to any collateral source whose payments actually reach the jury. Once a defendant puts that evidence on, the benefit source that made those payments loses its right to recover anything from the plaintiff and cannot be subrogated to the plaintiff’s claim against the defendant.¹

Without that trade-off, a jury could cut the award after hearing about insurance payments, and the insurer could still demand repayment out of what was left. The plaintiff would get squeezed from both sides. Division (C) blocks that outcome: if the defendant benefits from the evidence, the payer loses its reimbursement right.

Cases the Statute Does Not Reach

ORC 2315.20 applies only to “tort actions,” and the statute defines that term narrowly. It covers civil actions for injury, death, or loss to person or property, including product liability and asbestos claims. It explicitly excludes:¹

Medical claims against doctors, dentists, optometrists, and chiropractors.
Breach of contract claims.

The medical malpractice exclusion catches people off guard. If a surgeon botches your procedure and you sue, the traditional common-law collateral source rule still applies in full. The defendant cannot put your insurance payments before the jury at all. That distinction can swing the size of a verdict significantly, because malpractice cases often involve the largest medical bills.

Billed Charges Versus What Insurance Actually Paid

Separate from the collateral source statute, Ohio has its own rule about the gap between a hospital’s billed charge and the amount an insurer actually pays. A hospital might bill $50,000 while the insurer’s negotiated rate settles the account for $15,000. The $35,000 difference is a contractual write-off that nobody pays. In Robinson v. Bates, the Ohio Supreme Court held that both the original billed amount and the amount accepted as full payment are admissible to prove the reasonable value of the medical care. The write-off itself is not a “benefit” under the collateral source rule because no one paid it to you.²

In practice the jury sees both numbers and decides what the care was worth. On an $8,000 MRI bill paired with a $2,000 insurance payment, a juror might land somewhere in the middle. Robinson v. Bates runs alongside ORC 2315.20 but on a different theory: it addresses the reasonable value of services, not whether the plaintiff received a collateral benefit. Both questions come up in nearly every injury case involving insured treatment, and they often tangle together at trial.

How Subrogation Repayment Works After Recovery

When an insurer holds subrogation rights and successfully keeps its payments away from the jury, ORC 2323.44 governs how repayment is handled after the case resolves. The statute gives injured plaintiffs two meaningful protections.³

First, if you recover less than the full value of your claim because of comparative fault, limited policy coverage, or any other reason, the insurer’s subrogation claim shrinks proportionally. Recover 60% of your claim’s full value and the insurer’s reimbursement demand drops by 40%. The insurer cannot take a full-dollar repayment out of a reduced recovery.

Second, if you and the subrogee disagree about how to split the money, either side can file a declaratory judgment action and have a court sort it out. These disputes are common in larger cases and can hold up settlement funds for months, so it helps to know in advance that a resolution path exists.
