Connecticut Collateral Source Rule: Calculation, Exceptions, and Premium Credits

Connecticut’s collateral source rule, codified at Connecticut General Statutes §52-225a, requires the trial court to reduce the economic portion of a personal injury or wrongful death award by insurance and similar payments the plaintiff already received, minus whatever the plaintiff paid in premiums or contributions to secure those benefits, and only when the payer has no right to seek its own reimbursement. The reduction happens after the jury verdict, at a separate hearing, and it applies only to economic damages. Pain and suffering and other non-economic damages are untouched.

How the Reduction Is Calculated

The math under §52-225a runs in three steps. The court adds up every qualifying collateral source payment made on your behalf as of the judgment date. It subtracts the amounts you or your immediate family paid, contributed, or forfeited to obtain those benefits. It then reduces your economic damages by the difference.¹

Economic damages are the pecuniary losses: medical care, rehabilitation, custodial care, and lost earnings or earning capacity.² Non-economic damages — the category that covers pain and suffering, loss of enjoyment of life, and emotional distress — are not reduced at all. In cases where the non-economic award is the larger piece, the collateral source calculation touches only a slice of the verdict.

What Counts as a Collateral Source

The statute defines collateral sources narrowly. Under §52-225b, they include payments made under health or sickness insurance, automobile accident insurance providing health benefits, and any contract or arrangement by a group, organization, partnership, or corporation to cover hospital, medical, dental, or other health care costs. Life insurance benefits are expressly excluded.³

Settlement payments from other defendants are not collateral sources either. The Connecticut Supreme Court held in Mahon v. B.V. Unitron Manufacturing, Inc. that money a plaintiff received from other parties in settlement cannot be used to reduce the jury’s award, because the legislature left settlements out of the statutory definition.⁴ If you settled with one defendant and tried the case against another, those settlement dollars stay out of the collateral source math.

Two Exceptions That Block the Reduction Entirely

Even where a payment fits the definition, two statutory exceptions can keep the court from reducing your damages by it.

The first is subrogation. If the payer holds a right to seek reimbursement from the defendant or from your recovery, that payment cannot be used to reduce your damages. Connecticut case law reads this exception broadly: when any right of subrogation exists, the entire payment from that source is shielded. The exception reaches further than it looks, because many health insurers and most workers’ compensation carriers reserve subrogation rights as a matter of course.¹

The second is the comparative negligence offset. The portion of collateral source payments equal to the reduction in your economic damages caused by your own share of fault is also exempt. If the jury assigns you 20 percent of the fault and your damages are already cut by that percentage under Connecticut’s comparative negligence rules, the collateral source reduction cannot stack on top of that same slice.¹

Between them, these exceptions often absorb most of the reduction the defendant asks for. When a plaintiff’s health insurer has subrogation rights, the court cannot touch the award for those medical costs, and the insurer pursues its reimbursement separately.

Credit for the Premiums You Paid

Where a reduction does apply, you get a dollar-for-dollar credit for what you spent to obtain the benefits. Subsection (c) of §52-225a directs the court to receive evidence of amounts paid, contributed, or forfeited by you or your immediate family to secure the collateral source benefits at issue.¹ If an employer plan cost you $400 a month in payroll deductions, those contributions offset the reduction.

Pulling together the paperwork matters. Years of premiums add up, and the court cannot credit what nobody puts in front of it. Payroll records, premium statements, and benefits enrollment documents should be assembled before the hearing. If you had workers’ compensation deductions, union dues allocated to a benefits fund, or similar contributions, gather those too.

The Post-Verdict Hearing

None of this happens in front of the jury. The jurors never hear about your insurance, your Medicaid coverage, or any other payment source. The collateral source calculation takes place after the verdict and before the court enters judgment, at a separate hearing held by the judge.¹

At the hearing, the defendant presents evidence of every collateral source payment made on your behalf through the judgment date: explanation of benefits forms, payment records, provider statements. You respond with proof of your premium contributions, any subrogation rights that shield specific payments, and the comparative negligence offset if the jury assigned you any share of fault. The judge works through each collateral source individually, decides which ones qualify for reduction and which are exempt, and sets the final judgment.

Billed Amounts Versus What the Insurer Actually Paid

A common dispute involves write-downs. A hospital bills $50,000, the insurer’s negotiated rate is $18,000, and the hospital accepts that amount in full payment. Which figure drives the collateral source calculation? The statute allows evidence that a provider accepted less than the billed amount, or that an insurer paid less than the billed amount, as evidence of the collateral source payments made on your behalf.¹

The practical effect is that courts focus on amounts actually paid, not amounts originally billed. If your medical bills went to the jury at full charges but the insurer paid a fraction, expect the defendant to argue that the real collateral source figure is the paid amount. The write-down itself becomes contested ground over the true value of your economic loss.

Medicaid Payments and Government Liens

Medicaid-paid medical care sits in a particular corner of the analysis. Federal law requires Medicaid recipients to assign their rights to payment for medical care from third parties to the state as a condition of eligibility, and the state recoups its expenditures from the defendant’s payment or from the settlement proceeds.⁵ Because that reimbursement right functions as a form of subrogation, Medicaid payments typically fall within the §52-225a exception that keeps the court from reducing your damages for them.

The end result tends to be similar either way: the court does not reduce your economic damages, but Medicaid then collects its reimbursement out of your recovery. Settling and distributing proceeds without addressing a Medicaid claim can create real exposure, including liability for the full reimbursement amount even after the funds have been spent.

What the Statute Does Not Reach

Two boundaries are worth naming. The statute applies only to economic damages, so non-economic damages are not reduced for any collateral source payment, no matter how large. And §52-225a governs personal injury and wrongful death cases; the older common-law collateral source rule — which barred any reduction for payments from sources independent of the defendant — still governs matters outside the statute’s scope.⁶ If your case falls outside the statute, the rules are different from the ones described above, and the common-law analysis controls.
