A practice can determine whether rising collections are coming from better billing performance or simply more patients by comparing collections with encounters, charges, allowed amounts, A/R, and collection efficiency over the same period. If visits increase but collection performance per encounter also improves, billing may be contributing to the growth. If collections rise at roughly the same pace as patient volume while efficiency metrics remain unchanged, increased volume is likely doing most of the work.
Start With Collections Per Encounter
One of the simplest ways to separate volume from billing performance is to calculate:
Collections per encounter = Total collections ÷ Total encounters
For example, suppose a practice collected $200,000 from 2,000 encounters last year and $240,000 from 2,400 encounters this year.
Collections increased by 20%, but encounters also increased by 20%.
That alone does not demonstrate improved billing performance.
Now consider a different result: collections increase from $200,000 to $250,000 while encounters increase from 2,000 to 2,200. Collections grew faster than patient volume, which warrants further investigation into whether billing efficiency, reimbursement, payer mix, or service mix contributed to the difference.
Collections per encounter should therefore be viewed as a diagnostic metric, not proof by itself.
Review Net Collection Rate
The practice should also monitor its net collection rate (NCR) using a consistent calculation.
A simplified version is:
Net Collection Rate = Payments ÷ (Allowed Amount – applicable adjustments) × 100
The exact formula should remain consistent from period to period.
If patient volume increases while the net collection rate also improves, the practice has stronger evidence that revenue-cycle performance may be improving.
However, NCR can be affected by payer mix, contractual changes, timing, and the composition of the claims being measured. It should therefore be analyzed alongside other indicators rather than treated as a standalone answer.
Compare A/R Performance
Look at days in A/R and aging distribution before and after the increase in collections.
Ask:
- Is 90+ day A/R declining?
- Are unpaid claims being resolved faster?
- Is total A/R growing more slowly than charges?
- Are old insurance balances being recovered?
- Are denials being worked and appealed?
- Is payment posting keeping pace with deposits?
If collections are increasing while aged A/R is also accumulating rapidly, higher revenue may be largely attributable to increased activity rather than a healthier billing operation.
A structured A/R management process can help practices examine these balances by age, payer, claim status, and recovery activity.
Examine the Claims Behind the Collections
Do not stop at the cash number.
Compare:
Encounters → Charges → Allowed amounts → Payments → Adjustments → Remaining A/R
This helps determine whether more money is being generated because the practice is seeing more patients or because the existing revenue is being captured more effectively.
For example, if encounters increase by 15% but collections increase by 25%, investigate what produced the additional 10 percentage points. Possible explanations can include improved denial recovery, changes in payer mix, higher reimbursement, different services being performed, or more effective billing.
The numbers alone do not establish causation.
Track Denials and Clean-Claim Performance
Improved billing should often produce operational changes that can be measured.
Track:
- Claim rejection rate
- Denial rate
- First-pass or clean-claim performance
- Corrected claim volume
- Denial recovery
- Days from service to claim submission
- Days from payment receipt to posting
If collections rise while avoidable rejections and denials fall, that provides stronger evidence of improved revenue-cycle execution.
For practices evaluating broader medical billing services, these operational measures can be more informative than simply comparing one month’s collections with another.
Separate New Revenue From Recovered Revenue
Another important distinction is where the cash came from.
Break collections into categories such as:
Current-period insurance collections
Current-period patient collections
Prior-period A/R recovery
Denial and appeal recovery
Other adjustments or recoveries
A practice may experience a large increase in collections because a billing company successfully worked an old A/R backlog. That is different from generating more revenue from current patient visits.
For example, if a practice’s patient volume is flat but collections rise because previously unresolved claims are finally paid, the improvement is related to revenue recovery rather than increased patient volume.
Compare the Same Types of Data
Use consistent reporting periods whenever possible.
A useful monthly dashboard might look like this:
| Metric | Previous Period | Current Period | What It Tells You |
|---|---|---|---|
| Patient encounters | 2,000 | 2,200 | Volume change |
| Charges | $300,000 | $335,000 | Billing activity |
| Collections | $200,000 | $240,000 | Cash received |
| Collections per encounter | $100 | $109 | Revenue captured per visit |
| Net collection rate | 92% | 94% | Collection efficiency |
| Days in A/R | 48 | 43 | A/R velocity |
| A/R over 90 days | $75,000 | $61,000 | Aging improvement |
| Denial rate | 8% | 6% | Claim performance |
This type of trend analysis provides much more insight than saying, “Collections went up by $40,000.”
Be Careful With Payer Mix and Service Mix
A collection increase is not automatically the result of better billing.
Changes in payer mix, reimbursement rates, specialty services, procedure volume, coding patterns, provider productivity, or patient responsibility can materially affect revenue.
For example, a practice could collect more per encounter because it performed more reimbursable procedures, not because its billing company improved its claim workflow.
That is why the practice should compare similar periods and examine the underlying service and payer mix.
Establish a Baseline Before Changing Billing Companies
If the goal is to determine whether an outsourced billing company is improving performance, establish baseline measurements before the transition.
Record at least:
- Monthly encounters
- Monthly charges
- Monthly collections
- Net collection rate
- Days in A/R
- A/R aging
- Denial rate
- Rejection rate
- Clean-claim performance
- Collections per encounter
Then continue measuring those indicators after implementation.
This creates a much stronger basis for evaluating whether the billing partner is actually improving the revenue cycle.
The Medicator’s broader revenue cycle management services approach can be evaluated using these types of financial and operational measurements rather than relying on collections alone.
The Key Question to Ask
Instead of asking only:
“Did collections increase?”
Ask:
“Did collections increase faster than patient volume, while collection efficiency and A/R performance also improved?”
That question provides a much more useful starting point.
Rising collections can result from more patients, better billing, higher reimbursement, a different payer mix, stronger A/R recovery, or several factors at once. To isolate the effect of billing performance, compare collections with encounters, collections per encounter, net collection rate, A/R aging, denial trends, claim performance, payer mix, and service mix over consistent periods. The more of these indicators improve together, the clearer the practice’s financial picture becomes.
