Hospitals spend enormous amounts of time and resources managing revenue leakage, yet they still lose tens of billions of dollars to leakage annually.
They monitor denials, investigate underpayments, work aging A/R, appeal claims, correct billing errors, and look for opportunities to improve reimbursement.
Some of the heaviest hitters in the financial loss category according to 2025 data include:
- Denials & Payer Interventions: commercial outpatient claims were responsible for 10.3% of revenue leakage, while inpatients sat a little lower at 6.6%
- Front-End Oversight: 46% of initial claim denials stemmed from registration errors, unverified insurance eligibility and missing prior authorizations
- Mid-Cycle Gaps: while there’s no percentage attributed to these issues in the data, mid-cycle gaps such as incomplete clinical documentation, undercoding and unbilled charges contribute to the breakdown
- Underpayments: responsible for up to 11% of revenue leakage depending on the system, contractual underpayments have a sizable impact on net patient revenue
Consider another, lesser cited source of revenue cycle leakage: missed coverage.
Missed coverage is active, valid health insurance that goes undetected, unverified or unbilled—a scenario that can be responsible for a whole host of issues down the line.
When available insurance coverage isn’t identified, the hospital may never have the opportunity to bill the appropriate payer. The account can be routed incorrectly, inappropriately classified as self-pay, or move through the revenue cycle without the coverage that could have supported reimbursement.
That’s different from a denial, a denial tells you something went wrong.
Missed coverage means the opportunity was never captured in the first place, creating a drain on revenue that many hospitals aren’t even aware of.
Revenue Leakage Doesn’t Always Look Like a Denial
When revenue cycle leaders think about leakage, they often look at the points where money is visibly lost:
- denials
- underpayments
- uncaptured charges
- untimely claims
- uncollected patient balances
These problems are measurable because they leave a trail. Missed insurance coverage is different.
If an account is classified as self-pay because available insurance wasn’t identified, there may not be a denial telling the hospital that a payer should have been billed. The account simply follows a different path, and the revenue leakage happens before the organization has an opportunity to collect from the appropriate payer. Oftentimes, these accounts end their journey as a write-off.
The Wrong Payer Can Put the Entire Claim on the Wrong Path
Insurance information is foundational to the healthcare revenue cycle, we all know that.
If the payer information is incomplete, outdated, or incorrect, everything that follows is affected. A relatively small information gap at the front-end can create a much larger downstream problem, and the cost isn’t limited to reimbursement.
It can also include staff time, rework, delayed payments, increased A/R and additional, unnecessary patient communication. The earlier a coverage gap is identified, the fewer downstream processes have to compensate for it.
Why Does Coverage Get Missed?
Hospitals are often focused on the coverage they can see: the insurance a patient provides, the eligibility responses, or patients who present as self-pay.
What about the coverage no one knew to look for?
Some of the most common reasons coverage is missed include:
- Misclassified Self-Pay Accounts
- Unknown Secondary/Tertiary Coverage
- Outdated Intake Data
What you don’t know can hurt you—and what you don’t know you’re missing can be just as important as what you know.
Missed coverage isn’t a failure to verify information, it’s a failure to find something you didn’t know existed. That makes this type of leakage especially challenging: you can’t fix what you don’t know is there.
Self-Pay Isn’t Always the Same as No Coverage
Some patients are genuinely uninsured. Others may have coverage that wasn’t identified during the intake process. Those accounts can look identical in a traditional workflow: both appear as self-pay; but the underlying circumstances are very different.
There may be an opportunity to discover coverage that was never reported, wasn’t visible during registration, or changed after the patient’s information was collected.
That doesn’t however mean that every self-pay account has hidden insurance, it means self-pay status can sometimes be a signal that there’s more investigation needed.
Missed Coverage Creates More Than Lost Reimbursement
When coverage isn’t identified, the financial impact isn’t limited to the amount the hospital could have collected from the payer, there is also a cost associated with fixing the problem.
Consider everything that can happen after an account moves forward incorrectly:
Staff research the account, payer information is corrected, the claim is adjusted and rebilled. Additional documentation may be required, staff follow up with the payer and patient balances need to be corrected. The hospital is now spending resources solving a problem that could have likely been prevented earlier in the process.
Always ask the important question: Did we find all the insurance that could have been billed?
The First Answer Isn’t Always A Complete Answer
Here is where the concept of a second layer becomes particularly important.
A hospital takes care to verify coverage it knows about, and that’s essential. But verification and discovery aren’t the same thing—one focuses on confirming active coverage and one seeks to find coverage that hasn’t been identified yet.
Patients can have multiple forms of coverage; coverage can change, information can be missing our outdated and clues to additional coverage may exist in data a hospital already has.
The goal here is not to endlessly recheck every account, it’s to use data and technology to help identify where another look may uncover something meaningful.
That’s the role insurance discovery can play in addressing a part of revenue leakage that traditional processes may not fully capture.
Traditional Revenue Cycle Metrics May Not Tell the Whole Story
Hospitals track a wide range of critical metrics related to the revenue cycle, but they are largely related to what happens after coverage and billing information have entered the claims process.
What about accounts that never had the right payer attached? Staff won’t receive a denial, those accounts won’t show up on an underpayment report, nor will they trigger a work queue.
What you’re left with is a blind spot.
Look Beyond What You Already Know
Revenue cycle teams need a way to look beyond the information they already know. Leakage isn’t always caused about what went wrong with the claim, often it’s caused by what never made it there.
Consider this: What if the most valuable revenue opportunity is the one you didn’t know you were missing?
