Medicare makes billions of dollars in conditional payments every year for injuries or illnesses that may otherwise be someone else’s responsibility.
However, when these payments aren’t identified and resolved correctly, organizations risk penalties, reimbursements, and compliance violations; all emerging from one simple origin point: missing or misinterpreted medical information.
That’s exactly where medical record review becomes a critical compliance safeguard.
With MSP regulations now tightening and the Centers for Medicare & Medicaid Services (CMS) increasing oversight, the demand for accurate, efficient, and defensible medical record analysis has become more significant than ever before. Regardless whether you’re a payer, insurer, claims adjuster, attorney, or settlement planner, understanding the medical foundation of a claim is pivotal in ensuring that Medicare remains the secondary payer-not the primary.
In this post, we shall break down how medical record review supports Medicare Secondary Payer compliance, why precision matters, and how technology-driven solutions are changing the game.
What Is Medicare Secondary Payer (MSP) Compliance?
Medicare Secondary Payer regulations were set up to ensure that Medicare does not pay for services when another party is legally or contractually responsible. Examples include:
- Workers’ compensation insurers
- Liability insurers
- No-fault insurers
- Group health plans
- Personal injury settlements
When Medicare pays for care that should have been covered by another payer, it becomes a conditional payment, and CMS expects repayment, with interest.
Failure to comply can lead to:
- Penalties of up to $1,000/day/claim
- Delays in settlement
- Reimbursement demands
- Legal and financial exposure
- CMS audits and recovery actions
In all of this, the question often becomes:
“Who paid for what, and who should have paid for it?”
This is where comprehensive medical record review becomes an indispensable asset for the MSP compliance process.
Why MSP Compliance Depends on Accurate Medical Documentation
MSP decision-making relies heavily on medical evidence.
CMS, insurers, and legal teams need a crystal-clear picture of the claimant’s medical history, diagnoses, treatments, injury origins, and future medical needs.
However, there’s a challenge:
Medical records are voluminous, complicated and fragmented.
- A single case file can span from a few pages to thousands of pages.
- Key details may appear only once; buried deep within clinical notes.
- Diagnoses may be labeled differently across providers.
- Pre-existing conditions may mimic injury-related conditions.
Without a structured review, teams risk incorrectly associating treatments with the wrong payer, creating costly compliance issues.
How Medical Record Review Supports MSP Compliance
- Identifying Pre-existing vs. Injury-related Conditions
One of the biggest compliance pitfalls is incorrectly attributing medical care to the incident in question.
Medical record review helps clearly distinguish:
- Conditions that existed before the incident
- Conditions exacerbated by the incident
- Conditions directly caused by the incident
- Unrelated conditions
Why this matters:
Only the treatments linked to the compensable injury should be considered when evaluating CMS involvement, MSA allocations, or settlement negotiations.
Medical record review ensures only the right expenses are assigned to the claim.
- Mapping Treatment Timelines for Clear Causation
CMS expects clarity on timeline and causation. Medical records provide evidence, but only when properly interpreted.
A structured review helps identify:
- Date of injury/incident
- Onset of symptoms
- Gaps in treatment
- Unexpected or unrelated medical interventions
- Progression or resolution of conditions
Accurate timelines not only support MSP compliance but also strengthen claim defensibility and settlement reasoning.
- Verifying Medicare-eligible Treatment and Costs
When building a Medicare Set-Aside (MSA) or determining Medicare responsibility, reviewing records helps estimate:
- Future treatments
- Frequency of care
- Type of medical services needed
- Projected long-term costs
- Use of Medicare-covered vs. non-covered services
This ensures allocations fully meet Medicare Set-Aside compliance expectations, reducing the risk of rejection, re-review, or legal consequences.
- Detecting Ongoing Treatment Needs That Trigger MSP Obligations
A comprehensive review can uncover:
- Pending surgeries
- Continuation of therapy
- Long-term medication regimens
- Durable medical equipment (DME) needs
- Follow-ups and specialist consultations
These insights help ensure that settlements accurately account for future Medicare liability, thereby preventing a shift of responsibility to Medicare prematurely.
- Avoiding Conditional Payment Recovery Problems
CMS’s recovery contractors aggressively identify payment discrepancies. If Medicare has paid for treatments linked to the claim, recovery is inevitable.
Medical record review:
- Confirms whether the care was injury-related
- Helps validate or dispute CMS’s conditional payment letters
- Prevents overpayment on reimbursements
- Supports appeals or negotiations with precise evidence
In short: medical record review protects organizations from paying back more than they owe, or from overlooking amounts they must reimburse.
- Supporting Settlement Accuracy for MSA / MSP Cases
In MSA submissions, CMS demands detail. Any ambiguity boosts the chance of a denial or request for modification.
Medical record review helps ensure that:
- Every diagnosis is validated,
- Every treatment is correctly categorized,
- Every future need is justified,
- Non-related conditions are excluded,
- Documentation aligns with CMS expectations.
A well-reviewed medical file is the foundation of a compliant, defensible, and CMS-approved settlement.
- Enhancing Decision-making for Attorneys, Carriers & TPAs
Legal and insurance teams rely heavily on medical insights when making:
- Liability decisions
- Settlement evaluations
- Causation assessments
- Reserve setting
- Ongoing case strategy
Medical record review provides a clear, summarized, and digestible breakdown of the claimant’s medical condition, removing ambiguity and supporting more informed decisions.
- Mitigating Risks and Strengthening Compliance Audits
Medical record review helps create a documented trail of:
- What care was related
- How allocations were determined
- Why certain treatments were included/excluded
- Medical justification behind decisions
This documentation helps organizations remain audit-ready, compliant, and defensible.
The Growing Role of AI in Medical Record Review for MSP
Traditional medical record review is time-consuming and labor-heavy.
Today, AI-driven tools like ReviewGenX are transforming how MSP compliance teams process medical documentation.
AI enhances MSP compliance by:
- Extracting diagnoses, timelines, medications, and treatments instantly
- Identifying patterns and inconsistencies faster
- Flagging potential pre-existing conditions automatically
- Minimizing human error
- Accelerating case prep from 10+ hours to under 2
- Organizing every medical detail into structured, review-ready outputs
This combination of human expertise and AI-precision leads to better compliance, faster turnaround, and stronger case outcomes.
Why Accurate Medical Record Review Is Non-Negotiable for MSP
MSP compliance is fundamentally information-driven.
Therefore, missing even a single detail, like an overlooked pre-existing condition or an unrelated treatment can transfer Medicare responsibility incorrectly.
Medical record review ensures:
- Claims are properly evaluated
- CMS recovery actions are minimized
- Conditional payments are managed correctly
- MSAs are accurate and defensible
- Settlements meet CMS guidelines
- Financial and legal risks are significantly reduced
Simply put, medical record review is the backbone of MSP compliance.
