Medicare Advantage, the False Claims Act & Why Compliance Matters

If a diagnosis isn’t supported by documentation, it may be considered a false claim.

Medicare Advantage (MA) is growing quickly—but so is government oversight. Regulators are paying much closer attention to how diagnoses are documented and submitted for risk adjustment. Now their scope has expanded beyond health plans. Physician groups, ACOs, and provider organizations can also be held responsible.

At the center of this enforcement is the False Claims Act (FCA)—a law that allows the government to take action when incorrect claims are submitted for payment. In simple terms, if diagnoses are not accurate or properly documented, organizations could face serious financial penalties.

Why the Government Is Paying Attention

The Department of Justice (DOJ) has made Medicare Advantage fraud a top priority. In 2025, FCA recoveries hit $6.8 billion, with a large portion tied to MA cases. That’s a clear signal: risk adjustment is now a compliance issue, not just a revenue opportunity.

Here are the most common ways organizations get into trouble:

Reporting Diagnoses Without Proper Support
Every diagnosis submitted for risk adjustment must be backed by clear documentation in the medical record. If it’s not, the payment tied to that diagnosis could be considered a false claim.

For example, if a condition is listed but there’s no evidence that it was evaluated, treated, or monitored, it may not meet CMS requirements.

Not Fixing Mistakes in Time
If your organization finds out that a diagnosis was incorrect, you are required to fix it—and quickly.

Under the “60-day rule,” you must return any overpayment within 60 days of identifying the issue. If you don’t, it can turn into a “reverse false claim,” even if the mistake was unintentional.

Risky Financial Arrangements
Payment or incentive structures between health plans and providers must follow strict rules. If they violate the Anti-Kickback Statute, any related claims could automatically be considered false.

Why This Is So Challenging

It’s not just about capturing diagnoses—it’s about proving they belong there.

On paper, this all sounds straightforward: document accurately, code correctly, and fix errors quickly. In reality, it’s much harder. Patient records are long, complex, and scattered across different systems. A single chart can include:

  • Progress notes

  • Lab results

  • Specialist reports

  • Imaging

  • Hospital discharge summaries

Coders and clinicians often have to review dozens—or even hundreds—of pages to find the right information. Doing this manually takes time and increases the risk of missing something important.

Where Traditional Workflows Fall Short

Many organizations still rely on manual chart reviews or basic EHR tools. These approaches can miss key issues, such as:

  • Diagnoses that don’t have enough supporting documentation

  • Old conditions that were carried forward incorrectly

  • Missing details needed to meet CMS documentation standards

  • Errors that should have been corrected before submission

Without a reliable way to check documentation against each diagnosis, compliance gaps are almost inevitable.

The Need for Strong Compliance Support

Risk adjustment today isn’t just about capturing more diagnoses—it’s about making sure every diagnosis is accurate, properly supported, and audit-ready. That’s why strong compliance tools are essential. In the event of a claim denial or a payer RADV audit, clear documentation is critical to validate diagnoses, avoid audit failures, and protect your organization’s cash flow.

 
 

ForeSee Medical helps organizations go beyond basic coding. Using modern AI tools such as LLMs (Large Language Models), ForeSee reviews the full patient record—including hard-to-read documents like PDFs—and connects each diagnosis directly to the clinical evidence that supports it.

This makes it easier to:

  • Confirm that diagnoses meet documentation requirements

  • Catch unsupported or incorrect codes early

  • Improve documentation at the point of care

  • Prepare for audits with clear, traceable evidence

The Bottom Line

Medicare Advantage is under a microscope. With billions of dollars in FCA enforcement, the risks are real—and growing. Organizations can no longer rely on manual processes or outdated tools. Strong compliance isn’t optional—it’s critical. Because today, it’s not just about capturing diagnoses. It’s about proving they’re accurate, supported, and ready to stand up to scrutiny.
