Medicare Secondary Payer (MSP)

Medicare Secondary Payer (MSP) pertains to the cases when Medicare is not the primary payer for a beneficiary’s medical claims.¹ In such scenarios, an entity like an employer group health plan, workers’ compensation, or liability insurance is responsible for the payment of the major costs.²

This guide explains how the MSP process works, the instances where Medicare is not the main payer, and the ways of handling conditional payments to avoid hefty fines.

What is the Medicare Secondary Payer Act?

The Medicare Secondary Payer program encompasses a set of statutory requirements that aim at protecting the Medicare Trust Funds. Prior to 1980, Medicare was the primary payer for almost all services to beneficiaries, regardless of whether they had other insurance coverage.

To control the escalating healthcare expenses, Congress changed the payment hierarchy. Currently, Medicare pays only after “primary payers” have met their obligations. If these primary payers are delaying their payments, Medicare may issue a “conditional payment” to ensure the beneficiary gets the necessary care, with a promise of reimbursement later.³

1. Working Aged (Employer Group Health Plans)

If you are 65 or older and have an employer group health plan (GHP) through your own or your spouses current work, the employer matters.

2. Disability and Large Group Health Plans

Those under 65 who qualify for Medicare due to a disability have a different threshold for primary coverage. The Large Group Health Plan (LGHP) becomes the first payer if the employer has 100 or more employees.⁴

3. Workers’ Compensation and No-Fault Insurance

In case you are injured at work or in a car accident, the workers’ compensation or no-fault insurance is the primary payer. Medicare will not cover services related to that particular injury until the primary insurance is exhausted or denied.

4. Liability Insurance and Settlements

This is the area where the medicare secondary payer rules become most complex as Medicare usually pays the initial bills and then asks for reimbursement after a settlement is reached.⁵

The Role of the BCRC and CRC

CMS hired two primary contractors to manage these claims: the Benefits Coordination & Recovery Center (BCRC) and the Commercial Reparations Center (CRC).

The BCRC locates health coverage that is primary to Medicare and handles the recovery of overpayments in liability, no-fault, and workers’ compensation cases.⁶ Based on our testing of the Medicare portal, the BCRC is the entity most beneficiaries will interact with when reporting a pending claim.

Navigating Conditional Payments and Medicare Set-Asides (MSA)

When Medicare covers a service that should have been paid for by another insurer, it makes a “conditional payment.” Such a payment is made conditionally in the expectation of being paid back after a settlement or judgment.⁷

How to Manage Conditional Payment Letters (CPL)

After a claim is filed, the BCRC will send a Conditional Payment Letter (CPL).⁸ This letter shows every medical charge for which Medicare has paid in connection with your case.

During my numerous audits of these letters, I have observed that CMS frequently puts the unrelated charges—like standard physicals or unrelated prescriptions—in the total for recovery. It is up to you to dispute these line items within the stipulated time if you want to make sure that you are not overpaying the government.

Medicare Set-Asides (MSA)

While settling workers’ compensation or liability cases, one should also think of Figuring out future Medicare. A Medicare Set-Aside is a financial contract that dedicates a portion of a settlement to cover future medical services that would be paid by Medicare.⁹ This serves to satisfy the medicare secondary payer rules long after the case is closed.

Comparison Table: Medicare Payment Hierarchy

Scenario	Primary Payer	Secondary Payer	Employer Size Requirement
Working Aged (65+)	Employer GHP	Medicare	20+ Employees
Disability (Under 65)	Large GHP	Medicare	100+ Employees
End-Stage Renal Disease	GHP	Medicare	First 30 months of coverage
Workers’ Compensation	WC Carrier	Medicare	Any
Liability / No-Fault	Liability Insurer	Medicare	Any
Small Employer (65+)	Medicare	Employer GHP	< 20 Employees

Section 111 Reporting and Compliance for Insurers

Insurers and self-insured entities must comply with Section 111 of the Medicare, Medicaid, and SCHIP Extension Act of 2007.¹⁰ This requires “Responsible Reporting Entities” (RREs) to report all settlements involving Medicare beneficiaries to CMS.

Non-reporting may result in hefty civil monetary penalties.¹¹ From our analysis of recent CMS enforcement activities, we conclude that the government has become more proactive in locating insurers who try to evade the medicare secondary payer reporting system.

Expert Insights: Avoiding Common MSP Pitfalls

Based on my professional experience consulting on complex Medicare cases, the most common mistake is failing to report a claim early. As a result, they experience extended waiting times for receiving a final demand letter, which can then cause the settlement funds to be inaccessible.

Below are three actionable tips to simplify the procedure:

• Report Early: Initiate a case with the BCRC right after the filing of a claim, not its settlement.

• Audit Thoroughly: Do not accept the first Conditional Payment Letter as definitive; verify that ICD-10 codes correspond to your injury.

• Use the Portal: The Medicare Secondary Payer Recovery Portal (MSPRP) is the most efficient way to submit documents and monitor balances.¹² The time between requests and responses can be lengthened by using the mail or fax services.

Future Outlook: The PAID Act and Beyond

The Medicare coordination environment is never static. This is important because under the medicare secondary payer statute, Medicare Advantage has the same recovery rights as traditional Medicare.

Key Takeaways

• Medicare acts as a Secondary insurer when a beneficiary is covered by a large employer or in a liability/workers’ comp situation.¹³

• The 20/100 Employee Rules specify whether a Group Health Plan is primary or secondary based on the size of a company.

• Reporting is compulsory for insurers under Section 111, and strict penalties are imposed for non-compliance.¹⁴
• MSAs play a pivotal role in settlements to safeguard Medicare’s future and prevent the beneficiary from losing coverage.¹⁵

Conclusion and Next Steps

The medicare secondary payer scene is a maze of bureaucratic obstacles and tough legal stipulations. Complying with these rules, be it as a beneficiary safeguarding your settlement or an employer managing a group health plan, calls for constant vigilance and a thorough knowledge of CMS guidelines. Not heeding these rules might result in the loss of health benefits, lawsuits by CMS, and steep monetary penalties.
