Workers’ Compensation Medicare Set-Aside – Thresholds and Approval

A workers compensation medicare set aside is a pot of money carved out of your settlement and reserved to pay for future treatment of your work injury. Medicare will not pay for that treatment until the pot is spent correctly. This is not a tax and it is not a penalty. The money is still yours, but it is restricted. It sits in a separate account, it pays only injury-related bills that Medicare would otherwise cover, and it is reported to the government.

This guide explains the 2026 review thresholds, who decides the number, how repayment of past bills works, and what to ask the attorney handling your case. It describes a process only. It is not legal or medical advice.

Why a Workers Compensation Medicare Set Aside Exists

The rule behind it is the Medicare Secondary Payer statute, 42 U.S.C. 1395y(b). Congress said Medicare pays second when someone else is responsible. In a work injury, the comp carrier is responsible.

So when a settlement closes out future medical care, Medicare does not simply take over the bill. It expects the settlement money to be spent first. The workers compensation medicare set aside is how that expectation is measured and tracked. You can read the statute text at Section 1862 of the Social Security Act.

There are two separate money questions in every case. Past bills Medicare already paid are called conditional payments. Future bills are handled by the workers compensation medicare set aside. They are recovered by different offices and on different timelines. People confuse them constantly.

How Much a Workers Compensation Medicare Set Aside Takes

CMS will review a proposed amount only if the case clears a threshold. As of 2026, CMS reviews a proposal when the claimant is already a Medicare beneficiary and total settlement exceeds $25,000. It also reviews when the claimant has a reasonable expectation of Medicare enrollment within 30 months and total settlement exceeds $250,000.

Those figures come from Section 8.1 of the WCMSA Reference Guide, posted at the CMS Workers’ Compensation Medicare Set-Aside Arrangements page. CMS updates the guide several times a year. Confirm the current version and thresholds there, or with your attorney, before relying on a number.

Being under the threshold does not erase the obligation. It only means CMS will not formally review the file. The duty to protect Medicare’s interest still applies. Many carriers still fund a workers compensation medicare set aside below threshold and simply do not submit it.

The amount itself is built from your own records. An allocator reviews your treatment history, prescriptions and physician projections. Costs are priced at fee schedule or actual charges, then multiplied by your remaining life expectancy.

Here is a worked example. The numbers are round and invented for illustration only. Your case will differ.

The procurement reduction in that example follows 42 CFR 411.37. That regulation sets the formula for reducing Medicare’s recovery by the cost of getting the settlement. Example only. Do not use these figures for your own case.

Funding can be a single lump sum or an annuity with an initial seed and yearly deposits. A structured workers compensation medicare set aside spreads the cost for the carrier. It also means your account refills each year rather than sitting full on day one.

The Timeline From Injury to Final Demand

Step one. The carrier reports the claim under Section 111 mandatory insurer reporting. Since April 4, 2025, carriers must also report the set-aside amount on workers’ compensation settlement records. Reporting details are on the NGHP What’s New page.

Step two. The Benefits Coordination and Recovery Center, the BCRC, opens a recovery file. It identifies bills Medicare paid that relate to your injury.

Step three. The BCRC issues a Conditional Payment Letter. This is an interim figure, not a bill. It lists claims Medicare believes are injury-related and may include charges that are not.

Step four. Your attorney reviews the payment summary and disputes unrelated lines. Disputes are filed through the Medicare Secondary Payer Recovery Portal, the MSPRP. Portal registration and instructions are at Medicare’s Recovery Process.

Step five. Within 120 days of an expected settlement, your attorney can start the Final Conditional Payment process in the MSPRP. That locks a figure for a limited window. See the CMS Final Conditional Payment Process guide.

Step six. The workers compensation medicare set aside proposal is submitted through the WCMSA portal if the case meets a threshold. The portal is described at the CMS WCMSA Portal page. CMS may approve the proposed amount or counter with a higher one.

Step seven. After settlement, the BCRC issues the Final Demand. Payment is requested within 60 days of the demand letter date. Interest accrues from the demand date if the debt is not resolved in that window.

Step eight. You or a professional administrator opens the account and starts paying injury bills. Annual attestation is required. Rules are at CMS WCMSA Self-Administration.

How to Reduce What You Repay

Three levers exist, and none of them are guaranteed. First, procurement costs. Under 42 CFR 411.37, attorney fees and case costs reduce Medicare’s recovery proportionally, as shown in the example table.

Second, relatedness disputes. Medicare’s payment summary often includes treatment for unrelated conditions. Those lines can be challenged through the MSPRP with medical records supporting the objection.

Third, appeals and financial relief after the Final Demand. A beneficiary generally has 120 days from receipt of the demand to request a redetermination, the first appeal level. Separately, a waiver of recovery can be requested using form SSA-632-BK. CMS posts instructions at its SSA-632 waiver instructions page.

A compromise request is a different path, asking CMS to accept less than the full debt. Waiver and compromise are discretionary. No one can tell you the outcome in advance. Confirm current deadlines in your own demand letter, since the letter controls.

What Happens If You Get It Wrong

If the Final Demand goes unpaid, interest is assessed and the debt can be referred to Treasury for collection. Offset against future Social Security or tax refunds is possible.

The government can also sue under 42 U.S.C. 1395y(b)(3)(A), which allows double damages. That exposure can reach the beneficiary, the carrier and the attorney who distributed settlement funds.

If the set-aside account is spent on the wrong things, the consequence is narrower but real. Medicare can deny payment for your injury-related care until you show the money was spent properly. That is why receipts and annual attestation matter.

Questions to Ask Your Attorney

In almost every case the attorney handling your claim manages this process. They order the payment summary, dispute the lines, coordinate the allocation and pay the demand from the settlement trust account. You should still ask questions.

1. Does my settlement cross a 2026 review threshold, and will the workers compensation medicare set aside be submitted to CMS or not? 2. Who prepared the allocation, and can I see the report? 3. Is the account funded as a lump sum or an annuity, and what is the seed amount?

4. Will I self-administer the workers compensation medicare set aside or will a professional administrator do it, and who pays the fee? 5. What is the current conditional payment figure, what have you disputed, and when do you expect the Final Demand?

Frequently Asked Questions

Is a workers compensation medicare set aside required by law?

No statute names it. The Medicare Secondary Payer rule requires that Medicare’s interest be protected, and CMS treats a properly funded set-aside as the way to do that. It is the accepted method, not a listed requirement.

What if I am not on Medicare yet?

The 30-month reasonable expectation test still applies. If you have applied for Social Security Disability or expect to enroll soon, a workers compensation medicare set aside may still be needed above $250,000. Ask your attorney to document your enrollment status.

Can I spend the money on anything else?

No. Funds pay only for injury-related care that Medicare would otherwise cover, including prescriptions. Keep every receipt. If money remains at your death, it generally passes to your estate after Medicare’s interest is satisfied.

How long does CMS review take?

Review time varies by workload and by whether CMS requests more records. There is no guaranteed turnaround, and this article will not invent one. Ask your attorney what the WCMSA portal is currently showing for your submission.

What to Do Next

A workers compensation medicare set aside is normally managed by the attorney handling the injury case. Ask the firm in writing who is contacting the Benefits Coordination and Recovery Center, what is being held in escrow, and when you will see the final demand. If you have no attorney, your state bar’s referral service is the neutral place to start.
