Why MSP and COB Are Core Financial Controls—Not Just Compliance Tasks

Medicare Secondary Payer (MSP) and Coordination of Benefits (COB) processes are often treated as administrative or compliance-driven tasks. In reality, they play a direct role in payment accuracy, financial performance, and audit exposure for healthcare payers.

In this video, Imagenet Chief Compliance and Consultancy Officer Julie Hughes explains why MSP and COB should be viewed as core financial controls—and what payer organizations need in place to reduce risk, improve accuracy, and stay audit-ready.

When MSP and COB processes are handled inconsistently, the impact goes beyond compliance. Payer organizations may pay claims they don’t owe, miss recovery opportunities, and increase exposure to CMS audit findings.

Accurate primary payer determination ensures claims are paid correctly the first time, reducing overpayments, rework, and provider abrasion. Strong MSP and COB processes also protect financial performance by minimizing retroactive adjustments and improving reconciliation outcomes.

Payers that treat MSP and COB as core financial controls—not box-checking exercises—see cleaner data, fewer surprises, and significantly lower downstream risk.

What Strong MSP and COB Governance Looks Like

Effective MSP and COB governance is defined by how work actually runs day to day—not just documented policies.

Key elements include:

• Clear ownership across intake, eligibility, claims, finance, and recovery
• Early verification of coverage and third-party liability at enrollment and intake
• Validation of COB order before payment is issued
• Ongoing reconciliation of claims, eligibility, and recovery activity
• Consistent documentation of decisions, data sources, and adjustments

When these controls are routine, repeatable, and monitored, payer organizations reduce payment leakage, improve audit readiness, and maintain stronger operational control.

How Payers Can Strengthen MSP and COB Oversight

As regulatory scrutiny becomes more data-driven, payer organizations need to move from reactive correction to proactive oversight.

That means strengthening data governance across eligibility, claims, and recovery workflows, improving system integration, and establishing clear ownership and escalation paths. It also requires ongoing monitoring, regular reconciliation, and workforce readiness through training and audit simulation.

Organizations that operationalize MSP and COB as continuous risk management disciplines—not back-end clean-up—will be better positioned to manage compliance and financial performance over time.
