You’ve built your business from the ground up. You know your profit margins, your inventory, and your team. But there is a silent regulatory landmine that many small business owners walk over every single day: Medicare Secondary Payer (MSP) compliance.
It often starts with a well-intentioned conversation. An employee turns 65 and asks, "Hey, can I just drop the company health plan and go on Medicare? Maybe the company could just pay for my Medicare Part B or a Medigap policy instead?"
On the surface, it sounds like a win-win. The employee gets Medicare, and you save money on their group premium. But saying "yes" to that request could trigger an excise tax equal to 25% of your total group health plan expenses, a penalty that can easily exceed $25,000 for even a modest small business.
At Total Benefit Solutions Inc, we’ve seen how these "common sense" decisions can lead to catastrophic financial penalties. As your independent health insurance advocate, our job is to catch these risks before they catch you.
What Exactly is Medicare Secondary Payer (MSP)?

The Medicare Secondary Payer rules are a set of federal laws designed to protect the Medicare trust fund. Essentially, the government wants to ensure that if an individual has access to other health coverage, like a group health plan (GHP), that plan pays first whenever possible.
When you offer a group health plan, the law dictates whether your insurance is the "Primary" payer or the "Secondary" payer.
- Primary Payer: The insurance company that pays the bill first.
- Secondary Payer: The insurance company that picks up the remaining costs after the primary payer has finished.
If your plan is primary, Medicare becomes the secondary insurance with medicare acting as a safety net for what the group plan doesn't cover. If you get this hierarchy wrong, or if you try to steer employees toward Medicare to save yourself a few bucks, you are effectively shifting costs onto the federal government. And the federal government does not take kindly to that.
The "Magic Number 20" (The Threshold You Need to Know)
For most small businesses, the complexity begins with the "20-employee rule." This is the threshold that determines the medicare secondary payer rules for your specific company.
If you have fewer than 20 employees:
Generally, Medicare is the primary payer for your Medicare-eligible employees. Your group health plan is secondary. In this scenario, the strict "anti-incentive" rules are usually more relaxed, but compliance is still critical.
If you have 20 or more employees:
Your group health plan is primary for all active employees (and their spouses) who are 65 or older. Medicare is secondary. This is where the highest risks live. If you fall into this category, you are legally prohibited from offering any "financial or other incentive" for an individual to not enroll in a plan that would be primary to Medicare.
(Note: "20 employees" is calculated based on each working day in at least 20 weeks in either the current or preceding calendar year. Even part-time employees count toward this total.)
The Prohibited "Incentive" Trap

This is the most common place where small employers get into trouble. You want to be helpful, so you offer to help an employee with their Medicare costs. Under the law, this is seen as a "prohibited incentive."
Prohibited actions include:
- Offering a cash payment to an employee if they drop the group plan and switch to Medicare.
- Paying the premiums for an employee’s medicare supplement group plans or Medigap policy.
- Reimbursing an employee for their Medicare Part B or Part D premiums.
- Telling a new hire that they cannot join the group plan because they already have Medicare.
Even if you don't offer cash, simply treating Medicare-eligible employees differently, such as offering them a different benefit package or a longer waiting period, can be seen as a violation of medicare employer coverage regulations.
Breaking Down the Fines: The $25,000+ Reality

Why is the fine so high? Because the government uses a multi-layered approach to penalties. It isn't just one ticket; it’s a pile of them.
- Civil Money Penalties (CMP): The government can charge roughly $10,000 per violation. If you have three employees you "helped" off the plan, that's $30,000 right there.
- The 25% Excise Tax: This is the most devastating. Under Internal Revenue Code Section 5000, employers who violate MSP rules can be hit with an excise tax equal to 25% of the total expenses incurred for all their group health plans during the calendar year. If your company spends $100,000 on premiums for the whole team, your fine is $25,000.
- Reporting Penalties: You are required to report Medicare-eligible individuals on your plan. Failure to report accurately can result in fines of $1,000 per day, per individual.
- Double Damages: If Medicare pays a claim that your group plan should have paid, the government can sue you for double the amount they paid out.
When you add these up, the cost of "saving" a few hundred dollars a month on a premium is dwarfed by the potential for a six-figure legal nightmare.
How to Stay Compliant: Your 5-Step Checklist
Navigating group medicare plans and employer responsibilities doesn't have to be a guessing game. Here is how you protect your business:
- Know Your Count: Keep an accurate count of your employees (full-time and part-time) to know exactly when you cross that 20-employee threshold.
- Standardize Your Offers: Ensure that the group health plan you offer to your 25-year-old employees is identical in cost and benefit to the one you offer your 65-year-old employees.
- Hands-Off Medicare Premiums: Never, under any circumstances, pay for or reimburse an active employee's Medicare-related premiums (Part B, Part D, or Medigap).
- Audit Your Communications: Ensure your HR team (or whoever handles onboarding) isn't "suggesting" that older employees look into Medicare as a way to save the company money.
- Work with an Advocate: This is the most important step. Health insurance regulations change constantly. You need a partner who eats, sleeps, and breathes this stuff.
