Prevent denials at the front end
When it may fit: Eligibility and authorization denials are growing.
Evidence needed: Denial reasons by department and payer; front-end process data.
Trade-off: Prevention takes process change and training.

How to Investigate Hospital Revenue Leakage
Revenue leakage is money the hospital earned but did not collect. Finding it means separating what is possible to recover from what only looks that way.
1. The business problem
How much of what the hospital earned is it actually missing, and how much of that is real?
Every hospital loses some revenue between care delivered and cash collected, through denied claims, underpayments, missed charges and write-offs. Headlines about large “leakage” numbers are common. The numbers are usually ceilings, built from total denied dollars rather than from what could actually be recovered.
This matters because projects sized on the ceiling disappoint. Some denials are valid and will never be overturned, some are past appeal windows, and some cost more to chase than they are worth. A credible investigation sizes the realistic opportunity.
2. What the evidence can reveal
Leakage investigations work best when they distinguish levels of certainty:
- Calculated Denied dollars: charges on claims that were denied. This is a measurement, not a loss estimate.
- Calculated Possible exposure: denied dollars minus what has already been recovered. This is a ceiling.
- Information gap Verified recoverable revenue: the portion that claim-level review shows is valid, within appeal windows, and worth pursuing.
- Information gap Other leakage types: underpayments, missed charges and write-offs, which need different data.
Verified fact Industry reports on denials and leakage exist, but figures vary widely by hospital, payer mix and definitions, so they should not be applied to a specific hospital without that hospital’s own claim data.
3. Investigate the problem
In the synthetic hospital, denied dollars were $15.5M in FY26, up from $12.6M. Of those, 49.0% had been recovered, leaving possible exposure of $7.90M, up from $5.70M. Illustrative
Calculated The exposure rose faster than denied dollars, because the recovery rate fell from 54.8%. That is a meaningful signal: appeals and resubmissions are recovering less of a growing pool. It is a ceiling, not a recoverable amount. Some of it is valid denials, and some may be time-barred.
Information gap Sizing the opportunity requires sampling claims: what share of denials is valid, what share is still appealable, and what the cost of working them is. The experience’s scenario shows how the ceiling moves under explicit assumptions, but it cannot replace the sample.
4. Explore the interactive experience
Investigate it yourself.
Revenue Cycle Investigation: a claims dashboard with denial reasons, payers and A/R days, a denial-reduction scenario that separates possible exposure from verified revenue, evidence-linked answers from APIS, and a sample brief, all on synthetic data.
The experience below uses synthetic claims data for a fictional hospital. No patient data is involved, and every figure is illustrative.
- On the Dashboard, compare Denied dollars, Recovery rate and Possible exposure. Which moved most?
- Ask APIS “How much of the denied dollars could be recoverable?” and read how it frames the answer.
- In the Scenario tab, raise the recovery rate by 5 points and see how the ceiling moves.
5. Evaluate possible solutions
Reducing leakage means attacking it at different points. These options address different kinds.
6. What leadership should do next
Questions to answer
- What share of denied dollars is valid?
- What is still appealable?
- Where is recovery falling?
- Are underpayments or missed charges also leaking?
Data to gather
- Claim-level denial and appeal data
- Payer contracts and rules
- Expected versus actual payments
- Charge-capture audit results
Steps to take
- Separate denied dollars from possible exposure from recoverable.
- Sample claims to size the real opportunity.
- Rank causes by value and effort.
- Track recovery monthly.
7. Engage Two Pillars
Explore Your Hospital’s Opportunities
Two Pillars can help hospital leadership investigate financial, operational, and strategic questions using relevant organizational data, public information, and a structured assessment process. A good first step is a revenue integrity assessment that separates possible exposure from verified recoverable revenue using a claim sample.
