Tennessee’s collateral source rule stops a defendant in a personal injury case from reducing what they owe by pointing to payments you received from your health insurance, a government program, or any other outside source. The jury hears the full value of your damages and decides what the defendant owes based on that, not on a lower figure after insurance adjustments. The rule has one major exception written into statute for medical malpractice cases, and it does not protect you from the insurers and government programs that come looking for reimbursement after you recover.
What the Rule Protects in a Standard Injury Case
The reasoning Tennessee courts have used for the rule is simple: when a windfall has to land somewhere, it belongs with the injured person rather than the person who caused the harm. A negligent driver or property owner pays for the full extent of the damage no matter what outside sources already contributed.
In practice, the defense attorney cannot tell the jury that your private health insurance paid your hospital bills. Jurors never learn about those payments. They evaluate the total cost of your injuries and decide what the defendant owes without a running tally of what has already been covered. The rule reaches charitable care and free treatment too. If a doctor treated you at no charge, you can still recover the reasonable value of that care from the defendant, because a benefit from a third party is not supposed to become a discount for the person who hurt you.
Full Billed Amount or the Discounted Rate
The most contested question under the rule is which number the jury sees for your medical bills: the hospital’s full list price or the lower amount the insurer actually paid. The difference is often enormous. A hospital may bill $50,000 for a procedure where the insurer pays $15,000 under a negotiated contract.
The Tennessee Supreme Court settled this for standard personal injury cases in Dedmon v. Steelman (2017). Plaintiffs can present their full, undiscounted medical bills as evidence of reasonable expenses, and defendants cannot introduce the insurer’s negotiated rates to argue the charges were unreasonable.1Tennessee Administrative Office of the Courts. Jean Dedmon v. Debbie Steelman, Et Al. The defense can still challenge whether treatment was necessary or whether the charges were reasonable, but it has to do that with other evidence.
Dedmon drew a line against the earlier ruling in West v. Shelby County Healthcare Corp. (2014), which held that under the Tennessee Hospital Lien Act, “reasonable charges” means the discounted amount the hospital accepted from the insurer.2Justia. West v. Shelby County Healthcare Corp. That holding applies only to hospital lien disputes. In a personal injury suit against the party who caused your injuries, the collateral source rule still lets you present the full billed amount.
The Presumption for Bills Under $4,000
Tennessee gives plaintiffs a shortcut for proving smaller medical expenses. Under T.C.A. § 24-5-113, if you attach itemized medical bills to your complaint and the total does not exceed $4,000, those bills are presumed necessary and reasonable.3Justia. Tennessee Code 24-5-113 – Medical, Hospital or Doctor Bills – Prima Facie Evidence of Necessity and Reasonableness The defense can still rebut that presumption, but the burden shifts to them. For bills above the threshold, you need additional proof of reasonableness, usually expert testimony.
Medical Malpractice Cases Are Different
The collateral source rule essentially disappears when the defendant is a doctor, hospital, or other healthcare provider. Tennessee classifies those suits as healthcare liability actions, and a separate statute, T.C.A. § 29-26-119, explicitly abrogates the rule for them.4Justia. Tennessee Code 29-26-119 – Damages in Healthcare Liability Actions Your past economic losses are capped at what was actually paid or accepted as full payment. That covers insurance payments, government program reimbursement rates, and write-offs from charity or discount programs. If your insurer negotiated your $80,000 hospital bill down to $25,000, your recoverable economic loss is $25,000.
The defendant has to produce documentation of the reduction to trigger this limitation. Without the paperwork, the full billed amount stands. Fights over explanation-of-benefits records and payment histories are a regular feature of these cases.
Noneconomic damages, meaning pain and suffering and loss of enjoyment of life, carry a separate $750,000 cap under T.C.A. § 29-39-102, with a $1,000,000 cap for catastrophic injuries the statute defines by category.5Justia. Tennessee Code 29-39-102 – Civil Damage Awards That cap is not part of the collateral source rule, but it combines with the § 29-26-119 abrogation to make total recovery in a malpractice case substantially lower than what the same injuries would produce in a car accident suit.
What the Rule Doesn’t Do After You Win
Keeping the defendant from telling the jury about your insurance is not the same as keeping the insurer away from your recovery. After the verdict or settlement, several parties may have claims against your money, and the collateral source rule does not stop them.
Private Health Insurance and the Made-Whole Doctrine
Your health insurer may assert a subrogation claim to be repaid for the medical bills it covered. Tennessee’s made-whole doctrine blocks that claim until you have been fully compensated for all your losses. Tennessee courts apply the doctrine even when the policy contains express reimbursement language, which puts Tennessee among the more protective states on this point. If your settlement does not cover your full damages, the insurer may have to wait or accept less.
Self-Funded ERISA Plans
If your coverage comes through a large employer’s self-funded plan, the made-whole doctrine likely does not help you. These plans are governed by the federal Employee Retirement Income Security Act, which preempts state subrogation rules and lets a plan sue to enforce its terms, including a reimbursement provision tied to any injury recovery.6Office of the Law Revision Counsel. 29 USC 1132 – Civil Enforcement The U.S. Supreme Court confirmed in US Airways, Inc. v. McCutchen (2013) that the plan’s contract language controls and equitable doctrines like made-whole cannot override an express reimbursement provision.7Justia. US Airways, Inc. v. McCutchen, 569 U.S. 88 Whether your plan is self-funded or fully insured is the pivotal question, and the answer is in the plan documents, not on your insurance card.
Workers’ Compensation
If a third party caused a workplace injury, you can collect workers’ compensation benefits and sue that third party, but T.C.A. § 50-6-112 gives your employer or its workers’ comp insurer a subrogation lien on the third-party recovery.8Justia. Tennessee Code 50-6-112 – Actions Against Third Persons – Attorney’s Fees – Distribution of Recovery – Limitations Period The lien attaches whether or not the employer joins the lawsuit. If the recovery exceeds what the employer paid in benefits, the employer gets a credit against its future obligations for the excess. The made-whole doctrine does not apply; this statute controls.
Medicare
Under the Medicare Secondary Payer Act, Medicare is not meant to pay when another party is liable, and when it pays conditionally the federal government has a reimbursement right against any settlement or judgment.9Office of the Law Revision Counsel. 42 U.S. Code 1395y – Exclusions From Coverage and Medicare as Secondary Payer That right exists independent of state law and independent of the collateral source rule. The government can pursue the plaintiff, the plaintiff’s attorney, or the defendant directly. Settlements must account for Medicare’s conditional payments before funds are distributed, and ongoing treatment may call for a Medicare Set-Aside to protect future eligibility.
The rule prevents the defendant from using Medicare’s payments to shrink the verdict at trial. It does not prevent Medicare from collecting what it paid out of your share afterward. Those are separate questions, and treating them as the same is where plaintiffs lose money.
