Let’s be honest: talking about Medicare Secondary Payer (MSP) rules is about as exciting as watching paint dry in a room full of accountants. But here’s the kicker, if you’re a small business owner, ignoring these rules is a great way to watch your hard-earned profits vanish into a black hole of federal fines.
At Total Benefit Solutions Inc, we spend our days navigating the labyrinth of group health insurance for employers, and we’ve seen it all. We know that you’re just trying to provide affordable group health insurance without getting slapped by Uncle Sam. CMS (the Centers for Medicare & Medicaid Services) has a very specific sense of humor, and it usually involves sending you a bill for thousands of dollars because you checked the wrong box or didn't report a change in an employee's status.
I’m Ed MacConnell, and I’m here to break down the 15 things you absolutely need to know to stay out of the penalty box. Grab a coffee, and let’s dive into the witty, gritty world of MSP compliance.
1. The Magic Number is 20
If your company has 20 or more employees, your group health insurance for employers is primary. This means if an employee is 65 or older and still working, your insurance pays first, and Medicare pays second. If you have fewer than 20 employees, Medicare is generally primary.
Why does this matter? Because if you’re a group of 25 and you tell your 66-year-old top salesman to just use Medicare and drop off the company plan, you’re breaking the law. CMS counts "total employees," not just those on the plan. If you’re hovering around that 20-person mark, you need to be very careful with how you categorize your headcount.
2. "Active Employment" is the Golden Key
Medicare Secondary Payer rules only apply to "active" employees. Once an employee retires, the rules change. A retiree’s coverage is almost always secondary to Medicare. However, "active" can be a bit of a gray area if someone is on disability or a long-term leave of absence. At Total Benefit Solutions Inc, we help you determine the exact status of your team to ensure you aren't paying for claims that Medicare should be covering, or vice versa.
3. Don't Offer "Bribes" to Leave the Plan
It might be tempting to tell an older employee, "Hey, if you switch to Medicare, I’ll give you a $200 monthly bonus." Stop right there. This is what CMS calls a "prohibited incentive." Federal law strictly prohibits employers with 20+ employees from offering any financial or other incentive for a Medicare-eligible individual not to enroll in a plan that would otherwise be primary.
The penalty? Up to $5,000 per offer. Not per person who accepts: per offer. That’s a fast way to turn affordable group health insurance into a financial nightmare.
4. The $1,000-a-Day Headache
Under Section 111 of the Medicare, Medicaid, and SCHIP Extension Act (MMSEA), employers and insurers are required to report certain information about Medicare-eligible individuals to CMS. If you fail to report this information correctly or on time, you can be fined up to $1,000 per day for each individual.
In the world of level funded health insurance, where transparency is key, keeping your data clean is essential. We make sure our clients have the reporting tools they need so they aren't donating $365,000 a year to the government for a simple clerical error.
5. Billing Codes are Your Best Friends (or Worst Enemies)
If you’ve ever looked at a medical claim, it looks like a cat walked across a keyboard. But those codes matter.
- Code 12: Working-aged beneficiary (Your plan is primary).
- Code 14: No-fault insurance.
- Code 15: Workers' compensation.
- Code 47: Liability.
Using the wrong code: like defaulting to "liability" for a standard health claim: can trigger an audit. CMS expects precision. If you’re using Reference based pricing, where you pay providers based on a percentage of Medicare rates, the coding must be even more meticulous.
6. Conditional Payments are Not "Free Money"
Sometimes Medicare will pay a bill "conditionally" to make sure a patient gets care while two insurance companies argue over who is primary. If Medicare pays and then later determines your group plan should have been primary, they will come for their money. They call this a "recovery demand." It’s not a request; it’s a demand, and it often includes interest.
7. The 100+ Rule for Disability
While the 20-employee rule applies to age-based Medicare, the rules for disability-based Medicare are different. If your group has 100 or more employees, your plan is primary for employees (and their family members) who are eligible for Medicare based on disability. If you have 99 employees, the rules flip. It’s a subtle distinction that can lead to massive billing errors if your HR department isn't paying attention.
8. ESRD is a Different Beast Entirely
End-Stage Renal Disease (ESRD) has its own 30-month coordination period. Regardless of your group size, the employer plan is primary for the first 30 months of Medicare eligibility due to ESRD. After that, Medicare becomes primary. This is a high-cost area where many employers lose money by not tracking the calendar effectively.
9. COBRA and Medicare: The Messy Divorce
This is where most small business owners trip up. Usually, if you have Medicare, you don't need COBRA. If you have COBRA and then become eligible for Medicare, your COBRA can generally be terminated. However, if you have Medicare first and then lose your job, you can sometimes keep COBRA as secondary coverage.
It’s confusing, it’s messy, and if you get it wrong, you could leave an ex-employee with zero coverage and a lawsuit against you. This is why we recommend checking your plan documents regularly at www.totalbenefits.net to ensure your COBRA notices are compliant.
10. The EOB is Your Shield
When you are secondary to Medicare, you must provide the Explanation of Benefits (EOB) from the primary payer. Medicare won't pay a dime until they see what the primary insurer did. We often see claims stall because a doctor’s office didn't attach the right paperwork. As your broker, we jump in to bridge that gap between the provider and the carrier.
11. Reference Based Pricing (RBP) and Medicare
Some employers are moving toward Reference based pricing to save costs. RBP pays providers a multiple of Medicare (e.g., 140% of Medicare). While this is a great way to secure affordable group health insurance, it requires a deep understanding of MSP rules. You cannot use RBP to "dump" patients onto Medicare; the plan must still follow primary/secondary coordination rules.
12. Diagnosis Codes Must Match
If an employee is treating a chronic condition under the group plan and a specific injury under a Workers' Comp claim (where Medicare is also secondary), the diagnosis codes must be distinct. If they overlap, CMS might reject the entire claim, leaving the employer or the employee on the hook for the bill.
13. Spousal Coverage Matters
If your employee is 40 but their spouse is 66 and covered under your group plan, the 20-employee rule still applies. Your plan is primary for that spouse. You can't force the spouse onto Medicare just to save a few bucks on your premium. CMS views that as a violation of the "equal benefit" rule.
14. Level Funded Health Insurance Advantage
Many of our small business clients are switching to level funded health insurance. These plans offer the cost-savings of self-funding with the predictability of fully insured plans. Because these plans are often more data-driven, they actually make MSP compliance easier. You get better reports, which means you can spot a 65-year-old employee on the roster and adjust your primary/secondary designations before a claim is even filed.
15. The "Good Faith" Effort Isn't Enough
CMS doesn't care if you "tried your best." They care about compliance. The MSP rules are "strict liability" statutes. This means if you broke the rule, you’re liable, regardless of your intent.
