Understanding Medicare Set-Asides and When They Apply
What Medicare Set-Asides Are and Why They Matter
A Medicare Set-Aside (MSA) is money that gets set apart from a workers' compensation settlement or lawsuit award. Instead of going directly to the injured worker, this money stays in a special account to pay for medical treatment related to the work injury. The Centers for Medicare & Medicaid Services (CMS) established this process to protect Medicare's trust funds.

When someone receives workers' compensation money for an injury, Medicare may have already paid for some of that person's medical care. The government wants to make sure that injured workers don't receive duplicate payments for the same medical treatment. That's where the MSA comes in. By setting aside money from the settlement, the worker has funds specifically designated to cover future medical costs related to that injury before Medicare pays anything.
The basic concept works like this: Suppose a worker injures their back at work and receives a $100,000 settlement. CMS might determine that $40,000 of that money should go into an MSA for future back-related medical care. The worker would receive $60,000, and the $40,000 would sit in a separate account. As the worker receives medical treatment for the back injury, the MSA money pays those bills first. Only after the MSA is exhausted would Medicare pay for additional related care.
MSAs affect different groups of people in different ways. Workers who are already receiving Social Security Disability Insurance (SSDI) or are age 65 and older and receiving Medicare face MSA requirements. The amount set aside depends on several factors, including the worker's age, the severity of the injury, expected medical costs, and how long treatment might continue.
Without an MSA system, workers could receive both their full settlement payment and have Medicare pay for treatment of the same injury—essentially getting paid twice. This would drain Medicare resources. The MSA protects the Medicare trust fund while still allowing injured workers to receive appropriate compensation and medical care.
Practical takeaway: Understanding that an MSA is a protective mechanism—not a penalty—helps clarify why this requirement exists. It's designed to prevent double payment while ensuring injured workers still receive the money and care they need.
How Medicare Set-Asides Are Calculated
The calculation of an MSA amount involves several key variables. CMS does not use a simple formula that applies to everyone. Instead, calculations are based on individual circumstances that predict future medical needs. The primary factors include the worker's current age, life expectancy, the type and severity of the injury, and reasonable estimates of future medical treatment costs.

Age plays a significant role because younger workers may need medical care for decades. A 35-year-old worker with a permanent shoulder injury might need physical therapy, imaging studies, and injections for 50 years. A 70-year-old with the same injury might need care for only 10-15 years. CMS uses actuarial tables that estimate life expectancy based on age, which directly impacts the MSA amount.
The type of injury matters considerably. A herniated disc in the spine typically requires more ongoing medical care than a simple fracture that heals. Injuries involving multiple body parts, chronic pain conditions, or complications from initial treatment generally have higher MSA amounts. For example, an injury causing permanent nerve damage might require lifelong pain management, while a straightforward broken bone usually requires care only during the healing period.
Medical cost projections form the foundation of MSA calculations. These projections estimate what medical services the worker will need and what those services cost. The estimates include:
- Doctor visits and specialist consultations
- Diagnostic imaging (X-rays, MRI, CT scans)
- Physical therapy and rehabilitation
- Medications and injections
- Surgical procedures if anticipated
- Durable medical equipment like braces or assistive devices
- Home health services if needed
Professional economists often prepare detailed reports projecting these costs over time. They research current medical billing rates, anticipate inflation in healthcare costs, and account for the possibility that the injured worker may need more or fewer treatments than typical. Some injuries have clear medical protocols with predictable costs, while others are more variable.
CMS has published guidelines for how to calculate MSAs, though these are updated periodically. The agency recognizes that costs vary significantly by geographic location. Medical care in urban areas typically costs more than in rural areas. A physical therapy session in New York City costs more than the same session in rural Montana. Calculators and guidelines account for regional variations.
Workers' compensation attorneys and settlement negotiators often hire medical professionals and economists to prepare MSA calculations. These experts review medical records, research treatment protocols, and project future needs. The resulting report provides the basis for determining the MSA amount. The process can be detailed and technical, which is why professional guidance is common in larger cases.
Practical takeaway: MSA calculations aren't arbitrary numbers. They're based on age, injury type, medical costs, and life expectancy. Understanding these factors helps explain why two workers with similar injuries might have different MSA amounts.
When Medicare Set-Asides Apply
Medicare Set-Asides don't apply to every workers' compensation situation. Understanding when they're required helps workers know whether this process affects them. The primary determining factors are whether the worker receives Medicare benefits or will soon receive them.

MSAs apply when a worker is already receiving Medicare at the time of settlement. This includes people age 65 and older and younger people receiving Medicare through SSDI or End-Stage Renal Disease programs. If you're receiving Medicare payments when your workers' compensation case settles, an MSA will likely be required.
The threshold amount is also important. CMS requires an MSA when the projected medical costs for the work-related injury exceed $25,000 over the worker's lifetime. Cases with smaller anticipated medical costs typically don't require an MSA, as the administrative burden would exceed any benefit to Medicare. For example, a minor injury expected to cost $8,000 in treatment probably won't trigger MSA requirements, while a serious chronic condition expected to cost $75,000 in future care will.
These situations commonly trigger MSA requirements:
- A 68-year-old worker receiving Medicare benefits settles a workers' compensation case for a back injury. The projected medical costs exceed $25,000, so an MSA is required.
- A 55-year-old worker on SSDI due to diabetes settles a case for a knee injury. Even though they're younger than 65, they receive Medicare through SSDI, so an MSA applies if costs exceed the threshold.
- A 72-year-old worker settles a claim for shoulder surgery and physical therapy. Expected costs for ongoing care are $60,000. An MSA is required.
- A 45-year-old worker not yet receiving Medicare settles a case for a sprained ankle. No MSA is typically required because costs are below $25,000 and the worker isn't on Medicare.
Workers' compensation settlements and third-party liability lawsuits both can trigger MSA requirements if the conditions are met. If a worker receives a settlement for a work injury and is on Medicare, the MSA process generally applies regardless of the source of the settlement money.
The timing of Medicare eligibility matters. If someone is expected to begin receiving Medicare within 30 months due to age or disability, CMS may still require an MSA even if they're not currently receiving benefits. This prevents people from avoiding MSA requirements by timing settlements just before Medicare eligibility begins.
Not all medical settlements require MSAs. Settlements for non-work injuries usually don't involve MSAs, even if the injured person receives Medicare. The MSA process specifically applies to workers' compensation and employment-related injuries where Medicare might have paid for initial care.
Practical takeaway: You need to know if you receive Medicare and whether your projected medical costs exceed $25,000. These two factors determine whether an MSA applies to your settlement.
How Medicare Set-Asides Work in Practice
Once an MSA amount is determined and set aside, the money operates differently from a regular bank account. It's not simply deposited into a worker's checking account. Instead, specific account types and administration processes govern how the money is used and managed.
