Yes, Medicare Part B can be secondary insurance. When another health plan has the legal responsibility to pay your medical bills first, Medicare Part B steps in second and covers the remaining eligible costs. The federal law that controls this process is the Medicare Secondary Payer statute under 42 U.S.C. § 1395y(b), which Congress first expanded in 1980 to shift costs away from the Medicare Trust Fund and onto private insurers. This law creates specific rules based on your age, disability status, employer size, and type of coverage — and getting these rules wrong can lead to denied claims, surprise bills, or permanent premium penalties.
According to CMS, the MSP provisions have protected Medicare Trust Funds by billions of dollars each year by making sure Medicare does not pay for items and services that other health insurance is responsible for covering first. An estimated 12 million Medicare beneficiaries have some form of employer-sponsored coverage that may interact with their Medicare benefits.

What Does “Secondary Insurance” Mean?
Primary insurance is the plan that pays your medical bills first. It processes the claim according to its own coverage rules, deductibles, and benefit limits. Secondary insurance pays second — it picks up some or all of the remaining costs after the primary plan finishes.
When Medicare Part B acts as your secondary insurance, your other coverage (such as an employer group health plan) handles the bill first. Medicare Part B then reviews the remaining balance and pays its share of the approved charges. This coordination between two plans is called coordination of benefits (COB), and it follows strict federal rules.
The order of payment is not something you get to choose. Federal law — not your insurance policy, not your employer, and not your state — decides which plan pays first. Even if a private insurance contract says it pays secondary to Medicare, the MSP provisions override that contract when the law requires the private plan to pay first.
The Federal Law: Medicare Secondary Payer (MSP)
Congress created the Medicare Secondary Payer framework through a series of amendments to the Social Security Act, starting in 1980. The core statute lives at 42 U.S.C. § 1395y(b), and the implementing regulations sit in 42 C.F.R. Part 411. Together, these rules tell every insurer, employer, provider, and beneficiary exactly when Medicare pays first and when it pays second.
The MSP law covers several categories of insurance that must pay before Medicare. These include employer group health plans (GHPs), workers’ compensation, no-fault insurance, and liability insurance. Before 1980, Medicare was the primary payer for almost all claims except those covered by workers’ compensation, Federal Black Lung benefits, and VA benefits.
The reason Congress expanded these rules is straightforward: Medicare’s Trust Fund was absorbing costs that private insurers should have been paying. By making private plans pay first in certain situations, the MSP law shifts costs back to the responsible party and preserves Medicare funding for beneficiaries who have no other coverage.
When Medicare Part B Pays Secondary
Not every situation makes Medicare the secondary payer. The rules depend on why you qualify for Medicare, what type of other insurance you have, and how large your employer is. Here are the specific situations where Medicare Part B pays second.
Working Aged: Age 65+ With an Employer Group Health Plan
If you are 65 or older and still working — or your spouse is still working — and you have coverage through an employer group health plan, the employer size determines who pays first. When the employer has 20 or more employees, the group health plan pays primary and Medicare Part B pays secondary.
This rule applies whether you are the employee or you get coverage through your spouse’s job. It also applies if you are self-employed but covered under a group health plan through your spouse’s employer, as long as that employer meets the 20-employee threshold.
The employee count includes all employees — full-time and part-time — regardless of whether they participate in the health plan or qualify for Medicare. The employer must have 20 or more employees for each working day in 20 or more calendar weeks in the current or previous year. Once an employer meets this test, the MSP rules kick in right away and remain in effect through at least the following calendar year.
Disability With an Employer Group Health Plan
If you are under 65 and qualify for Medicare because of a disability, a different threshold applies. Your employer group health plan pays primary and Medicare Part B pays secondary only when the employer has 100 or more employees (or at least one employer in a multi-employer group employs 100 or more people).
This higher threshold exists because Congress recognized that smaller employers should not bear the same primary-payer burden for disabled workers as large employers. If the employer has fewer than 100 employees, Medicare is the primary payer for disabled beneficiaries.
End-Stage Renal Disease (ESRD)
If you develop End-Stage Renal Disease and qualify for Medicare based on ESRD, your group health plan pays primary during the first 30 months of your Medicare eligibility. This is called the 30-month coordination period. During this window, Medicare Part B is secondary regardless of employer size.
After the 30-month coordination period ends, the roles flip. Medicare becomes the primary payer, and your group health plan becomes secondary. This transition happens automatically based on the calendar — you do not need to file paperwork to switch the payment order.
No-Fault and Liability Insurance
If you are in a car accident or another situation where no-fault or liability insurance applies, that insurance pays primary for all health care services related to the accident. Medicare Part B pays secondary. This rule applies regardless of your age, employer size, or reason for Medicare eligibility.
The statute defines liability insurance broadly. It includes self-insurance, which means any business that carries its own risk — whether by choice or by failing to obtain insurance — counts as a liable party under the MSP rules.
Workers’ Compensation
When you have a job-related illness or injury covered by workers’ compensation, that workers’ compensation plan pays primary. Medicare Part B generally will not pay for services that workers’ compensation covers. However, if workers’ compensation denies part or all of a claim because it determines the service falls outside its scope, you can submit a claim to Medicare for the denied portion.
Before settling any workers’ compensation case, both parties must consider Medicare’s future interests. This often involves creating a Workers’ Compensation Medicare Set-Aside Arrangement (WCMSA) to account for future Medicare-covered services related to the injury.
When Medicare Part B Pays Primary
Understanding when Medicare is not secondary is just as important. In these situations, Medicare Part B pays first, and your other coverage picks up what remains.
Employer With Fewer Than 20 Employees
If you are 65 or older and your employer (or your spouse’s employer) has fewer than 20 employees, Medicare Part B is your primary payer. The group health plan pays secondary. This rule exists because Congress did not want to place the full primary-payer burden on small businesses.
COBRA Coverage (Non-ESRD)
If you are 65 or older or disabled and your only other coverage is COBRA continuation coverage, Medicare Part B pays primary and COBRA pays secondary. The one exception is ESRD: if you have ESRD and are within the 30-month coordination period, COBRA pays primary and Medicare pays secondary during that window.
This is a critical distinction. Many people assume COBRA works the same way as active employer coverage, but it does not for Medicare purposes. Once you leave your job and elect COBRA (and you already have Medicare), Medicare takes the primary role immediately — unless ESRD applies.
Retiree Health Plans
If you are 65 or older and have a retiree health plan from a former employer, Medicare Part B pays primary. The retiree plan pays secondary. A retiree plan is not the same as coverage through current employment, and this difference matters enormously for billing and claims processing.
The 20-Employee Threshold: A Closer Look
The 20-employee rule is the single most important factor for workers aged 65 and older. Getting this number wrong affects every claim you file, and both you and your employer bear responsibility for getting it right.
Here is how CMS counts employees for the MSP employer size test:
- The count includes every employee — full-time, part-time, seasonal — regardless of whether they are enrolled in the health plan
- An employee does not have to work on a particular day to be counted
- The employer must have 20+ employees on each working day in at least 20 calendar weeks in the current or preceding year
- Once the employer hits the 20-week threshold during a year, the MSP rules apply immediately and carry through the entire next calendar year
- If the employer drops below 20 employees after meeting the threshold, the MSP rules still apply through the end of the current calendar year
For multi-employer plans (like union plans), the 20-employee test is met if at least one participating employer has 20 or more employees. This means even a small employer participating in a union health plan could see its employees subject to the MSP rules if another employer in the group is large enough.
Scenario 1: Still Working at 65 With a Large Employer
Meet David. David turns 65 in March and works full-time for a company with 150 employees. He has group health insurance through his employer. David enrolls in Medicare Part A (which is premium-free for him) but decides to delay Part B because his employer plan covers doctor visits and outpatient services.
David’s employer plan is primary because the company has more than 20 employees. Medicare Part A acts as secondary for hospital stays. Because David has coverage through current employment at a large employer, he qualifies for a Special Enrollment Period and can delay Part B without penalty.
| Situation | What Happens |
|---|---|
| David visits his doctor for a checkup | Employer plan pays first; if David had Part B, it would pay the remaining approved charges |
| David delays Part B enrollment | No penalty because he has qualifying employer coverage through current employment |
| David retires at age 68 | He gets an 8-month SEP to enroll in Part B without penalty |
| David misses the 8-month SEP window | He must wait for the General Enrollment Period (Jan 1–Mar 31) and pays a permanent 10% annual penalty |
When David retires, he loses his current-employment coverage. At that point, Medicare becomes primary. David has exactly 8 months from the date his employer coverage or employment ends (whichever comes first) to sign up for Part B through the Special Enrollment Period without any penalty.
Scenario 2: Disabled and Covered by a Large Employer
Meet Sarah. Sarah is 52 years old and receives Social Security Disability Insurance (SSDI). After the mandatory 24-month waiting period, she becomes eligible for Medicare. Sarah’s husband works for a company with 200 employees, and she is covered under his employer group health plan.
Because the employer has 100 or more employees, the employer plan is primary and Medicare Part B is secondary. Sarah’s plan processes every claim first, and Medicare pays the remaining approved charges second.
| Situation | What Happens |
|---|---|
| Sarah goes to a specialist | Husband’s employer plan pays first; Medicare Part B pays the remaining eligible amount |
| Husband’s employer has only 50 employees | Medicare Part B pays primary; the employer plan pays secondary |
| Husband retires and elects COBRA | Medicare Part B becomes primary; COBRA pays secondary |
| Sarah turns 65 | The “working aged” rules (20-employee threshold) replace the disability rules |
The 100-employee threshold for disability MSP is different from the 20-employee threshold for working-aged beneficiaries. This catches many people off guard. If Sarah’s husband works for a company with 60 employees, the employer plan would pay primary under the working-aged rules (because 60 is above 20) for someone 65 or older — but it would not pay primary for Sarah’s disability-based Medicare because 60 is below the 100-employee threshold.
Scenario 3: ESRD and the 30-Month Coordination Period
Meet Tony. Tony is 45 years old and is diagnosed with End-Stage Renal Disease. He starts dialysis and becomes eligible for Medicare based on ESRD. Tony works for a mid-size company and has group health insurance.
During the first 30 months of Tony’s Medicare eligibility, his employer group health plan pays primary. Medicare Part B is secondary. This 30-month coordination period applies regardless of the employer’s size — it does not matter if Tony’s company has 10 employees or 10,000.
| Time Period | Who Pays First |
|---|---|
| Months 1–30 of Medicare eligibility | Employer GHP pays primary; Medicare Part B pays secondary |
| After month 30 | Medicare Part B pays primary; employer GHP pays secondary |
| Tony loses his job during month 15 and takes COBRA | COBRA pays primary through month 30; Medicare becomes primary after month 30 |
| Tony receives a kidney transplant during month 20 | The 30-month clock keeps running; employer plan remains primary until month 30 |
One important detail: if Tony had Medicare before developing ESRD (for example, because of a disability), the ESRD coordination period still applies. The 30-month window begins when Medicare eligibility based on ESRD starts, even if Tony already had Medicare coverage for another reason.
COBRA and Medicare Part B: A Dangerous Intersection
COBRA coverage is one of the most misunderstood areas of Medicare coordination. The rules depend on when you obtained Medicare relative to when you became eligible for COBRA.
If you had Medicare before becoming eligible for COBRA: You can elect COBRA, but Medicare pays primary and COBRA pays secondary. This happens when, for example, you are already 65 with Medicare and then lose your job. COBRA supplements Medicare — it does not replace it as the primary payer.
If you became eligible for COBRA before getting Medicare: The situation is more complex. If you elected COBRA and then become eligible for Medicare, your COBRA coverage may end. Under federal law, an employer can terminate COBRA coverage when a beneficiary becomes entitled to Medicare after electing COBRA.
The ESRD exception changes everything. If you have ESRD and are within the 30-month coordination period, COBRA pays primary and Medicare pays secondary — even though COBRA is normally secondary to Medicare. This narrow exception exists because Congress wanted to protect ESRD patients during their initial treatment window.
Never rely on COBRA as your primary coverage after age 65 unless the ESRD exception applies. If you do, your claims may process incorrectly, and you could face delays, denials, and billing disputes that take months to resolve.
TRICARE, VA Benefits, and Retiree Plans
Military veterans and retirees face unique coordination questions when they become Medicare-eligible. Each program interacts with Medicare Part B in a different way.
TRICARE for Life
TRICARE for Life (TFL) is available to military retirees, their spouses, and certain dependents. When you turn 65, Medicare becomes primary and TRICARE for Life acts as secondary. This means Medicare pays first, and TFL covers most of what Medicare does not — including Medicare’s deductibles and coinsurance.
Here is the critical requirement: you must enroll in both Medicare Part A and Part B to keep TRICARE for Life. If you fail to enroll in Part B, you lose your TFL coverage. This is true even if you are still working. There is no exception, and the consequences are immediate — you will have a coverage gap and may face Part B late enrollment penalties on top of losing TRICARE.
VA Health Benefits
VA health care operates on a separate system from Medicare. Medicare does not pay for services you receive at VA facilities, and the VA does not bill Medicare. However, if you receive care from a non-VA provider, Medicare can pay for those services as primary.
Having VA benefits does not exempt you from Part B enrollment rules. Many veterans choose to enroll in Medicare Part B alongside their VA benefits so they have the flexibility to see non-VA doctors. If you rely only on VA care and later want Medicare, you may face the late enrollment penalty because VA coverage does not qualify as “coverage through current employment” for SEP purposes.
Employer Retiree Health Plans
A retiree health plan from a former employer is not the same as coverage through current employment. When you have a retiree plan and turn 65, Medicare Part B pays primary and the retiree plan pays secondary. This distinction matters because many retirees assume their former employer’s plan works the same way it did while they were employed. It does not.
Some retiree plans are designed to wrap around Medicare, similar to a Medigap policy. Others reduce their benefits once Medicare kicks in. Read your retiree plan documents carefully, because your out-of-pocket costs may change significantly once Medicare becomes primary.
The Special Enrollment Period (SEP) for Part B
The Special Enrollment Period exists to protect people who delay Part B because they have qualifying coverage through current employment. Without the SEP, anyone who did not sign up during their Initial Enrollment Period (the 7-month window around their 65th birthday) would face a permanent late enrollment penalty.
You qualify for the SEP if you or your spouse is currently working and you have group health plan coverage based on that employment. The SEP allows you to enroll in Part B at any time while you have this coverage, plus an additional 8-month window after the employment or coverage ends.
Key details about the SEP:
- The 8-month SEP starts the month after employment ends or employer coverage ends, whichever happens first
- COBRA does not count as coverage through current employment for SEP purposes
- Retiree coverage does not trigger or extend a SEP
- VA benefits and TRICARE do not qualify as employer group health plan coverage for the SEP
- If you miss the 8-month window, you must wait for the General Enrollment Period (January 1 through March 31) and your coverage will not start until July 1 of that year
The SEP is your lifeline for avoiding the Part B penalty. Understanding which types of coverage qualify — and which do not — is essential to protecting yourself financially.
The Part B Late Enrollment Penalty
If you do not sign up for Part B when you are first eligible and you do not qualify for a Special Enrollment Period, you will pay a late enrollment penalty for as long as you have Part B. For most people, this means a permanent surcharge added to every monthly premium.
The penalty equals 10% of the standard monthly premium for each full 12-month period you could have had Part B but did not. In 2026, the standard Part B premium is $202.90 per month. If you delayed enrollment by two full years, the math works out to a 20% penalty — an extra $40.58 per month on top of your standard premium.
Here is a breakdown of how the penalty grows:
| Years of Delay | Penalty Percentage | 2026 Monthly Penalty | Total Monthly Premium |
|---|---|---|---|
| 1 year | 10% | $20.29 | $223.19 |
| 2 years | 20% | $40.58 | $243.50 |
| 3 years | 30% | $60.87 | $263.80 |
| 5 years | 50% | $101.45 | $304.40 |
This penalty is not a one-time fee. It recalculates each year based on the current standard premium, which means it grows as premiums increase. A person who delays Part B by five years could pay tens of thousands of dollars in extra premiums over their lifetime.
Mistakes to Avoid
These are the most common — and most expensive — errors people make when Medicare Part B is or should be their secondary insurance.
Mistake 1: Assuming COBRA Keeps Part B Secondary
After you leave your job, COBRA is not current-employment coverage. If you are 65 or older, Medicare becomes primary the moment your active employment ends — even if you elect COBRA. Relying on COBRA as primary means your claims will be processed in the wrong order, leading to denials, delays, and potential balance billing.
Mistake 2: Not Telling Providers About Your Coverage Order
Every time you visit a doctor or hospital, the provider needs to know which insurance is primary and which is secondary. If you give them only your Medicare card when your employer plan is primary, the claim goes to Medicare first. Medicare may pay conditionally, but it will later demand repayment — with interest.
Mistake 3: Dropping Part B Because You Have Employer Coverage
Some workers at large employers drop Part B because they feel their employer plan is “enough.” While the employer plan pays primary, dropping Part B means you lose your safety net. If you later retire or lose your job, you face a gap in coverage and a permanent late enrollment penalty. The safer choice is to keep Part B as secondary while your employer plan is primary.
Mistake 4: Confusing Retiree Coverage With Active Coverage
A retiree health plan does not make Medicare secondary. When you have a retiree plan, Medicare pays primary. If you assume the retiree plan is primary and delay Part B enrollment, you will have a coverage gap and owe the late enrollment penalty.
Mistake 5: Missing the 8-Month SEP Window
After your employment or employer coverage ends, you have exactly 8 months to sign up for Part B. Miss this window and you must wait until the next General Enrollment Period in January through March, with coverage not starting until July 1. That gap could mean 4 to 7 months without Part B coverage, plus a permanent penalty.
Mistake 6: Ignoring the TRICARE for Life Enrollment Requirement
Military retirees must enroll in Medicare Part B to keep TRICARE for Life. If you skip Part B because you think TRICARE alone is sufficient, you will lose your TFL benefit entirely. Reenrolling in Part B later triggers the penalty, and your TRICARE gap cannot be reversed retroactively.
How Claims Work When Part B Is Secondary
When Medicare Part B is secondary, a specific billing process must happen in the right order. Understanding this process helps you avoid surprise bills and payment delays.
Step 1: You receive medical services from a provider. The provider asks which insurance is primary.
Step 2: The provider submits the claim to your primary insurance (for example, your employer group health plan). The primary plan processes the claim, pays its share, and issues an Explanation of Benefits (EOB).
Step 3: The provider (or you) submits the remaining balance to Medicare along with the primary insurer’s EOB. Medicare reviews the claim under its own coverage rules and pays its secondary share of the approved amount.
Step 4: If there is still a balance after both plans pay, you are responsible for the remainder — unless you have a third layer of coverage, like a Medigap policy.
If incorrect information about your coverage reaches Medicare or your primary insurer, payments can be delayed or denied. The Benefits Coordination and Recovery Center (BCRC) is Medicare’s specialized contractor that tracks your other insurance coverage, coordinates payments, and resolves disputes. You should contact the BCRC whenever your insurance situation changes.
Do’s and Don’ts
Do’s
- Do tell every provider which insurance is primary and which is secondary — incorrect billing order causes claim denials and repayment demands
- Do enroll in Part B during your Initial Enrollment Period even if your employer plan is primary — Part B as secondary provides valuable backup coverage with no penalty risk
- Do contact the BCRC when your employment status, insurance coverage, or marital status changes — outdated records cause payment errors
- Do keep copies of all Explanations of Benefits from both your primary and secondary insurers — you need these documents if there is a billing dispute
- Do understand your employer’s size before assuming your plan is primary — the 20-employee threshold for working-aged and the 100-employee threshold for disability determine everything
- Do enroll in Medicare Part B before age 65 if you have TRICARE for Life — failure to enroll means losing TFL
Don’ts
- Don’t assume COBRA is the same as active employer coverage — it is not, and Medicare becomes primary once active employment ends (unless ESRD applies)
- Don’t delay Part B enrollment based on VA coverage alone — VA benefits do not qualify for the Special Enrollment Period
- Don’t ignore the 8-month SEP deadline — missing it results in a gap in coverage and a permanent premium penalty
- Don’t let your employer tell you to drop Medicare because the company plan is “better” — this violates MSP anti-discrimination rules and federal law prohibits employers from incentivizing employees to reject Medicare
- Don’t file claims with Medicare first when your employer plan is primary — conditional payments will be demanded back later with recovery proceedings
Pros and Cons of Medicare Part B as Secondary Insurance
Pros
- Lower out-of-pocket costs — with two plans covering the same service, your personal expenses shrink because the secondary plan picks up much of what the primary plan leaves behind
- Broader provider access — your employer plan covers its network, and Medicare covers Medicare-accepting providers, giving you more choices for care
- Protection during transitions — if you lose your employer coverage, Medicare is already in place as a safety net and can flip to primary immediately
- No Part B penalty — by enrolling in Part B while you have employer coverage, you avoid the permanent late enrollment penalty that would otherwise apply when you retire
- Coordination with Medigap — if you also have a Medicare Supplement policy, it can pay after Medicare processes the claim as secondary, further reducing your costs
Cons
- Extra monthly premium — you pay the Part B premium ($202.90 in 2026) even though your employer plan is handling most of the bills
- Billing complexity — two-payer claims take longer to process and require correct coordination between your employer plan and Medicare
- Potential for errors — if providers bill the wrong payer first, you may receive confusing EOBs, delayed payments, or demands for repayment
- IRMAA surcharges — high-income beneficiaries pay more for Part B through the Income-Related Monthly Adjustment Amount, which adds to the cost of maintaining secondary coverage
- Limited secondary benefit for some services — if your employer plan already covers 100% of a service, Part B as secondary pays nothing additional because there is no remaining balance
Key Entities and Their Roles
Understanding who does what in the MSP system helps you navigate claims and disputes.
- CMS (Centers for Medicare & Medicaid Services): The federal agency that administers Medicare and enforces the MSP rules. CMS sets the policies, publishes the manuals, and oversees compliance.
- BCRC (Benefits Coordination and Recovery Center): Medicare’s specialized contractor that manages MSP records, tracks your other insurance, coordinates payments, and recovers conditional payments. Call 1-855-798-2627 for BCRC assistance.
- SSA (Social Security Administration): Handles Medicare enrollment, including Part B sign-ups, Special Enrollment Periods, and penalty determinations. You apply for the SEP through your local Social Security office.
- Your Employer: Required to offer the same benefits to Medicare-eligible employees as it offers to younger employees. Employers must identify individuals subject to MSP and ensure their plans make proper primary payments.
- Medicare Administrative Contractors (MACs): Process Medicare claims in their assigned jurisdictions. When Part B is secondary, the MAC processes the claim after receiving the primary insurer’s EOB.
State Nuances
The MSP statute is federal law, and it preempts conflicting state laws and private contracts. However, state laws still play a role in several areas.
Some states have their own coordination-of-benefits regulations that affect how secondary claims are processed between non-Medicare payers. These state rules apply when you have two private plans but do not override the federal MSP framework when Medicare is involved.
Workers’ compensation laws vary by state. While the MSP statute makes Medicare secondary to workers’ compensation nationwide, each state defines which injuries qualify for workers’ compensation, what benefits are available, and how disputes are resolved. These state-level differences affect which claims reach Medicare as secondary and which do not.
No-fault auto insurance laws also differ by state. In no-fault states, your auto insurance pays for medical care after an accident regardless of who caused it — and Medicare is secondary to those payments. In states without no-fault laws, liability insurance determines payment, and Medicare is secondary to the liable party’s coverage. The federal MSP statute governs Medicare’s secondary status in both scenarios.
FAQs
Can Medicare Part B be secondary to an employer plan?
Yes. If you are 65 or older and work for an employer with 20 or more employees, your employer plan pays first and Medicare Part B pays second.
Does Medicare Part B pay secondary to COBRA?
No. Medicare pays primary and COBRA pays secondary — unless you have ESRD and are in the 30-month coordination period.
Can I delay Part B if my employer plan is primary?
Yes. You qualify for a Special Enrollment Period and can enroll in Part B penalty-free while you have employer coverage or within 8 months of it ending.
Is Medicare Part B secondary to workers’ compensation?
Yes. Workers’ compensation pays first for job-related injuries and illnesses. Medicare may pay if workers’ compensation denies part of the claim.
Do I need Part B if I have TRICARE for Life?
Yes. You must enroll in both Part A and Part B to keep TRICARE for Life. Skipping Part B causes you to lose TFL coverage.
Is Medicare secondary to VA benefits?
No. Medicare does not pay for care received at VA facilities. For non-VA care, Medicare pays based on its own rules regardless of VA enrollment.
Does the Part B penalty apply if my employer plan was primary?
No. If you had group health plan coverage through current employment, you qualify for a SEP and can enroll without a penalty.
Can my employer force me to drop Medicare?
No. Federal law prohibits employers from offering incentives or pressuring employees to reject Medicare when the employer plan is primary.
Is Medicare Part B secondary to no-fault auto insurance?
Yes. No-fault insurance pays primary for accident-related medical services. Medicare Part B pays the remaining approved charges.
What happens if I have Medicare and a retiree plan?
No, a retiree plan does not make Medicare secondary. Medicare Part B pays primary, and the retiree plan pays secondary.
Can I have both Medicare Part B and an employer plan at the same time?
Yes. Millions of Americans carry both. The MSP rules simply determine which plan pays first based on employer size and your eligibility category.
Who do I contact if my claims are processed in the wrong order?
Yes, you can fix this. Contact the Benefits Coordination and Recovery Center (BCRC) at 1-855-798-2627 to update your insurance records.
