How Healthcare Underpayments Impact Revenue Cycle Management

Is your practice protected from underpayments? It should be. In 2023 alone, hospitals absorbed roughly $130 billion in underpayments from Medicare and Medicaid alone. This has come to be known as a “silent” drain on revenue because, as common as they are, underpayments are often overlooked. The problem isn’t new but it’s quickly getting worse. Studies show that underpayment shortfalls grew by an average of 14% annually between 2019 and 2023.

Underpayments are situations where a provider is reimbursed for less than the expected or contracted amount for services by an insurance company or other payer. These are not denials. The practice receives a partial payment. That makes it more difficult to detect the error within a routine medical billing workflow. Another reason underpayments are often overlooked is that they are commonly small payment variance discrepancies. These discrepancies, however, can add up over time to become substantial losses.

Margins are tightening in the healthcare industry, and every dollar must be protected. Underpayment recovery has become an essential function of effective revenue cycle management. Because of this, automated revenue cycle tools are vital to prevent revenue leakage and maintain financial stability.

Understanding Healthcare Underpayments

Underpaid claims are very different from clinical denials. When a claim is denied, the provider is notified and given reasons for the denial. The provider can then make corrections and re-submit. This is costly and time-consuming, but often results in full payment. Underpayments go through as normal payments and are often overlooked.

Payer reimbursement methods, fee schedules, bundled payments, and contract-specific rules complicate payment calculations, further concealing inadequate payments. It isn’t necessarily as sinister as it may sound at first. Many underpayments are mistakes resulting from missed contract updates and outdated payer contracts. Whatever the reason, they can be costly and difficult to catch.

Without a strong, automated detection system, recurring underpayment issues can quietly erode cash flow. Small percentage losses can, over time, become very expensive. The frustrating thing is that these discrepancies are hiding in plain sight and creating significant revenue leakage.

Common Causes of Underpayments

What causes these payment discrepancies? Let’s take a look at these errors on both the payment and billing sides of the transaction.

Payer-Related Causes

Insurance companies sometimes pay the wrong amount because their systems apply outdated fee schedule updates or incorrect contract rates. Even when a claim is processed normally, the reimbursement may not match what the provider contract requires.

Claims may be processed with services bundled incorrectly, codes reduced to lower-paying versions, or modifiers misunderstood. These processing mistakes can lower the payment amount even when the original claim was coded correctly.

A payer may approve a prior authorization or agree to certain payment terms in payer contracts but then fail to apply those terms when the claim is processed, resulting in a lower reimbursement than the provider was promised.

Industry-Level Causes

Insurance plans are becoming more complex, and payers frequently update their rules and reimbursement policies. These constant changes increase the risk of payer issues and make it harder for providers to track correct payment amounts.

Many revenue cycle teams are short-staffed while handling large volumes of claims. With so much work to process, staff often do not have enough time to manually review payments and catch underpaid claims.

Some organizations still rely on basic billing systems that cannot automatically flag payment differences. Without automation or machine learning, it becomes difficult to identify discrepancies across thousands of claims.

RCM Causes

The Impact of Underpayments on RCM

So, what impact do underpayments actually have on your bottom line?

Studies estimate that providers lose one to three percent of revenue annually, while some studies have shown losses of up to 11%. In 2025, 41% of providers reported denial rates of 10% or higher, which illustrates the increasing reimbursement pressure in the industry.

Historically, Medicare has lagged behind the cost of care, and this trend continues with the government agency covering about 83 cents per hospital dollar spent in 2023.

What does this mean in practical terms?

A 20-provider group that generated $13.3 million per year in net revenue annually stands to lose between $133,000 and $399,000. That lost revenue represents capital that could have been used for staffing, technology investments, or clinical equipment. These underpayment issues also affect valuation and can become a serious concern during mergers, acquisitions, or private equity review.

Detection and Analytics: Identifying Underpayments

Underpayments tend to get lost in the shuffle and can be difficult to identify manually. An automated healthcare revenue cycle system makes spotting underpayments much easier.

These platforms perform automated payment variance analysis and contract modeling to quickly identify discrepancies between expected and actual reimbursement. AI-powered tools use machine learning to analyze claims data and detect patterns in underpaid claims across payers or service lines.

These systems generate detailed variance reports that help organizations analyze root cause issues and monitor trends throughout the entire revenue cycle.

Strategic Solutions for Underpayment Recovery

1. Identify Recovery Opportunities

When performing audits, it makes sense to look at your high-volume or high-dollar claims first to maximize your potential revenue recovery and recover lost revenue.

2. Group and Prioritize Accounts

Organize underpaid claims by payer, dollar value, and service line. Prioritize accounts that are approaching appeal or filing deadlines.

3. Dedicate Resources to Collect on Underpaid Accounts

Payer follow-up and escalation should be handled by experienced revenue cycle staff who know how to escalate payer issues effectively.

4. Incorporate Automation to Streamline the Recovery Process

Automated platforms help identify discrepancies, generate appeal documentation, and track payer responses. These tools integrate with contract management systems to calculate expected reimbursement automatically.

5. Focus on Future Prevention by Analyzing Root Causes

Once recurring underpayment issues are identified, teams can analyze root cause problems such as payer adjudication errors or coding errors. Organizations can then provide direct feedback to payers and internal teams to prevent underpayments and reduce future underpayments.
