This is Part 2 in our three-part series on revenue leakage. In Part 1, we explored how partial denial resolutions—often mistaken as “paid” claims—can quietly drain revenue from even well-run organizations. In this article, we’ll focus on how to identify and quantify that leakage so you can begin to take control of it strategically.

You Can’t Fix What You Can’t See

Partial denials are one of the more elusive threats in healthcare revenue management—not because they’re rare, but because they’re rarely visible. Most practice administrators, CFOs, or revenue cycle leaders don’t clearly understand how often partial denials occur, what they cost, or where the patterns are coming from.

And that’s the first problem.

If a claim shows up as “paid” in your system, it’s easy to assume there’s nothing more to review. But buried inside that payment might be denied service lines, missing modifiers, or improperly bundled codes—all of which represent revenue you were entitled to but didn’t receive.

The first step to recovery is recognition. You need a way to isolate, measure, and segment partial denials so they no longer hide in your reporting.

Step 1: Create a Reporting View That Separates Partial Payments

Most billing systems and dashboards aren’t configured to flag partial denials as a standalone category. If your platform doesn’t offer this out of the box, you’ll need to customize your reports or work with your analytics team to create a new view.

At a minimum, your report should:

• Flag claims where some charges were paid, and others were denied
• Capture denial codes tied to those service lines
• Include billed amount, paid amount, and variance
• Allow you to filter by payer, CPT code, location, or provider

The goal is to surface patterns—not just in dollars, but in frequency. A recurring $40 denial across 1,000 claims is a $40,000 problem.

Step 2: Segment by Payer Behavior and Denial Reason

Once you’ve isolated your partial denials, the next step is understanding the why behind them. Grouping denials by payer can reveal behavior patterns-some of which may reflect policy abuse or systemic errors on their end, not yours.

Look for:

• Repeatable CPT codes or service lines being denied
• Denial reason codes that are vague or inconsistent
• Denials clustered around specific payers or plan types
• Billing dates that may correlate with policy changes

This is where things often get interesting. You may find that a single payer is responsible for 60% of your partial denials—or that a certain type of claim is being underpaid due to documentation gaps.

These patterns don’t just help you fix the problem internally. They also provide leverage for payer escalations or contract renegotiations. 

Step 3: Translate the Data into Leadership-Level Insights

Quantifying revenue leakage only matters if the findings reach the decision-makers. Your final step is to turn raw data into insights that inform budgeting, staffing, process changes, and vendor evaluations.

We recommend packaging your findings into three simple outputs:

• Total dollars lost to partial denials over a rolling 12-month period
• Top five causes of those denials (with dollar impact per category)
• A brief narrative on the operational or process gaps contributing to the issue

When presented clearly, this information empowers leadership to connect revenue loss with specific breakdowns—whether in front-end verification, coding, documentation, or payer contracting.

A Common Finding: You’re Closer Than You Think

One of the most revealing outcomes we’ve seen when working with clients is this: the data is already there—it just hasn’t been looked at through the right lens.

Many groups are surprised to discover they’re losing six figures annually to patterns they assumed were already resolved. In some cases, just changing how teams view denial data has led to immediate process improvements and reclaimed revenue—without adding new headcount or major systems.

For organizations looking to turn insight into action, OncoSpark can help. We work with billing teams and leadership to create visibility, uncover patterns, and implement strategies that reduce leakage long-term. Whether you need guidance on analytics or hands-on services to support your team, our solutions are designed to meet you where you are.

If you’re unsure where the gaps are, we also offer a complimentary consultation to help assess the problem and explore next steps.

Closing Thought: Visibility Precedes Control

You can’t stop revenue leakage until you see it clearly. Partial denials represent a form of financial erosion that doesn’t sound alarms—but quietly undermines your bottom line.

Start with measurement. Get specific. Then, apply that clarity to strategic decisions.

In Part 3 of this series, we’ll explore how to build smarter workflows, clearer accountability, and leverage technology to prevent partial denials from recurring-without overwhelming your team.
