Revenue leakage rarely looks like a major financial crisis.
More often, it happens quietly: a missed charge, an eligibility error, a recurring denial, an underpayment no one catches, or an A/R balance that continues aging without a clear explanation.
Each issue may seem manageable on its own. Repeated across hundreds or thousands of claims, however, those small breakdowns can create significant financial impact.
That is why a revenue cycle audit should be part of every practice’s year-end financial review.
The goal is not simply to look at collections and determine whether revenue increased or decreased. A meaningful audit asks a more important question:
Are we consistently capturing, billing, collecting, and reporting the revenue we have earned?
For practice owners and CFOs, September is an ideal time to ask that question. There is still time to identify recurring problems, correct workflows, recover outstanding revenue where possible, and charge capture, coding, claim submission, reimbursement, A/R, and patient collections.
An effective audit should evaluate:
- Patient registration and demographic accuracy
- Insurance eligibility and benefits verification
- Prior authorization and referral processes
- Charge capture
- Clinical documentation and coding
- Claim rejection and denial trends
- Timely filing
- Payment posting
- Accounts receivable aging
- Payer reimbursement and underpayments
- Patient balances and collections
- Credit balances and refunds
- Revenue cycle performance metrics
- Staff workflows and accountability
The HFMA MAP Keys provide industry-standard revenue cycle KPIs for measuring performance across areas including patient access, pre-billing, claims, account resolution, and financial management.
Industry benchmarks can tell you whether a metric is outside an expected range. They cannot tell you why.
That is where the audit matters.
The objective is to connect the numbers to the processes producing them and identify where revenue is being lost, delayed, or unnecessarily tied up.
1. Denials Are Increasing—or Nobody Knows Why
A rising denial rate is an obvious warning sign. A bigger concern is when leadership cannot identify the primary causes, financial impact, or recurring patterns behind those denials.
Recent MGMA research found that denials and appeals were identified as the largest source of revenue cycle leakage reported by medical practices, followed by front-end issues, billing and collections, and coding.
Review:
- Denials by payer
- Denials by provider or location
- Denial reason codes
- Dollars associated with each category
- Appeal and overturn rates
- Time required to resolve denials
- Recurring denial patterns
Then ask:
Why are we seeing the same denial more than once?
If the same issue continues month after month, it is probably not a problem with individual claims.
It is a process problem.
Adding more staff to work the denial queue may increase activity without addressing the reason the denials keep occurring.
2. A/R Is Aging Without a Clear Explanation
A large A/R balance can create a false sense of security. Revenue sitting on a report is not the same thing as cash in the bank.
Look closely at A/R over 60, 90, 120, and 150 days. Then break it down by payer, provider, location, procedure, and claim type.
The goal is to determine what is actually preventing payment.
Is the claim denied? Waiting on documentation? Held for a payer issue? Billed incorrectly? Truly collectible?
One of the most important questions leadership can ask is:
Why is this money still outstanding?
If the answer is simply that the billing team is “working the A/R,” the practice may be measuring activity rather than results.
3. Services Are Being Performed but Not Consistently Captured
You cannot collect revenue you never bill.
Compare scheduled services, documented services, charges entered, and claims submitted. Look for gaps between those stages.
Potential red flags include:
- Services documented but not charged
- Delayed charge entry
- Missing ancillary charges
- Inconsistent charge capture between providers
- Manual processes that depend on staff remembering to enter charges
If the service never enters the billing workflow, the billing team never has an opportunity to collect it.
Charge capture should therefore be reviewed as part of the entire revenue cycle—not treated as a separate billing function.
4. Coding Patterns Are Inconsistent
Coding should accurately reflect the services provided and supported by the documentation.
Look for unusual variations among providers performing similar services. Review procedure codes, diagnosis codes, modifiers, and documentation supporting billed services. A billing integrity audit can help identify patterns that may be affecting both reimbursement and compliance.
And don’t look only for overcoding.
Undercoding can also represent lost revenue.
CMS reported a 10.3% improper payment rate for Medicare E/M services for the 2024 reporting period, with incorrect coding and insufficient or missing documentation among the leading causes.
If one provider consistently bills at a lower level than peers performing comparable services, that deserves investigation.
The objective is not aggressive coding. It is accurate coding supported by appropriate documentation.
5. Front-End Errors Are Creating Back-End Problems
Many revenue problems begin before the claim ever reaches billing.
Incorrect insurance information, outdated demographics, eligibility issues, coordination-of-benefits problems, and authorization errors can all create downstream denials and delays.
Review:
- Eligibility verification procedures
- Insurance information collection
- Demographic updates
- Coordination-of-benefits processes
- Registration accuracy
- Authorization requirements
- Communication between front-desk and billing staff
If billing staff are spending significant time correcting information that should have been verified before the visit, the solution may not belong in billing.
The best revenue cycle fixes often happen upstream.
6. Authorization Problems Keep Turning Into Denials
If authorization-related denials are recurring, take a hard look at the workflow.
Audit:
- Services requiring authorization
- Payer-specific requirements
- Responsibility for obtaining authorization
- Where authorization information is documented
- Whether authorization numbers transfer correctly to claims
- Authorization dates and units
- Denials associated with authorization
The objective should not be to become better at fixing authorization denials.
It should be to prevent them.
7. Payers Are Paying—but Are They Paying Correctly?
A paid claim is not necessarily a correctly paid claim.
Underpayments can be particularly difficult to identify because the claim processed and generated a payment. On a basic collections report, everything may appear fine.
Compare actual reimbursement against contracted rates for high-volume procedures and services. If discrepancies are recurring, a payor contract review may uncover reimbursement issues that are affecting the practice’s revenue.
Look for recurring discrepancies by:
- Payer
- Procedure code
- Provider
- Location
- Contract
Even a small reimbursement discrepancy can become significant when repeated across hundreds or thousands of claims.
Getting paid is not the same as getting paid correctly.
8. Patient A/R Continues to Grow
Patient responsibility is an increasingly important part of the revenue cycle, which means practices need a deliberate strategy for collecting those balances.
Review:
- Patient A/R aging
- Point-of-service collections
- Statement volume
- Returned statements
- Payment plans
- Unresolved balances
- Collection rates
- Bad debt
The question is not simply whether patients owe money.
It is whether the practice has a consistent, appropriate, and patient-friendly process for collecting what is legitimately owed.
9. Your Reports Tell You What Happened—but Not Why
This may be the most overlooked red flag.
Most practices have access to revenue cycle metrics. They can see collections, A/R, charges, and denial rates.
But can leadership answer why those numbers changed?
If days in A/R increased, what caused it?
If collections decreased, which payer or service line contributed?
If denials increased, what specifically drove the change?
If A/R over 90 days is growing, where is the money stuck?
A dashboard can show you that something happened.
A meaningful revenue cycle analysis helps you determine why—and what needs to change.
Revenue Leakage Is Usually a Pattern
Revenue Leakage Is Usually a Pattern
Revenue leakage rarely comes from one major billing mistake.
More often, it is the cumulative effect of small problems that repeat throughout the revenue cycle—a missed charge that happens dozens of times, an eligibility issue that creates recurring denials, or a payer underpayment that goes unnoticed across hundreds of claims. Even an inefficient workflow can create significant financial impact when staff spend hours each week correcting problems that could have been prevented upstream.
The financial impact also extends beyond the revenue that is never collected. Every denial requires staff time to investigate and resolve. Every registration error creates rework. Every unpaid claim requires follow-up. And every underpayment that goes undetected represents revenue the practice may never recover.
The key is identifying where those patterns begin.
If eligibility errors are driving denials, the practice may need to strengthen front-end verification. If one payer accounts for a disproportionate share of aging A/R, leadership needs to determine what is causing the delay. If underpayments are recurring, actual reimbursement should be compared against contracted rates. And if providers or locations show inconsistent charge patterns, the practice should examine documentation, coding, and charge capture.
A successful audit should do more than identify the problem. It should show leadership where to intervene.
What Should You Do With the Findings?
An audit is only valuable if the practice acts on what it finds.
Once the major leakage points are identified, prioritize them based on:
Financial impact. Frequency. Correctability.
Start with problems that are costing the practice the most, happening repeatedly, and realistically can be corrected.
Then assign ownership and define the next step. That may mean changing a workflow, clarifying responsibility between departments, developing a payer-specific strategy, reviewing coding, analyzing a contract, or improving reporting and accountability.
The solution is not always more staff.
Sometimes it is a better workflow. A clearer responsibility. Better reporting. A payer-specific strategy. A coding review. A contract analysis. Or stronger accountability between departments.
The goal is to stop treating revenue cycle problems as isolated incidents and start addressing the systems creating them.
Don’t Wait Until December to Find Out Where Your Money Went
Year-end should be a time to evaluate performance, not the first time leadership discovers that revenue has been leaking for the past 12 months.
A focused revenue cycle audit can uncover where money is being delayed, denied, underpaid, missed, or unnecessarily tied up in A/R. More importantly, it can help practice owners and CFOs determine whether they are dealing with a people problem, a process problem, or a breakdown somewhere in between.
Your billing team may be working hard. Your front-desk staff may be doing everything they know to do. Your providers may be documenting appropriately.
And you can still have a revenue cycle problem.
When workflows, reporting, payer processes, and accountability are not working together, revenue can leak through the cracks—and those leaks can continue month after month without appearing obvious on the surface.
That is where an experienced revenue cycle review can make a difference.
