Key takeaways
- Name the charge group and receipt cutoff.
- Compare equal elapsed collection windows.
- Preserve earlier snapshots for older work.
- Keep later outcomes unknown until observed.
Which collection rate are you comparing?
A collection rate divides the chosen receipts by the chosen charge base. The labels need dates as well as definitions. Receipts during a month and receipts eventually applied to that month's work answer different questions. Even two correctly matched service groups can look different if one has had much longer to collect.
Dentrix Ascend describes its Collection Success report as collections divided by production, displayed by month. Collection Success report. That period view should not be assumed to follow each service group for an equal length of time.
Open Dental's payment-split documentation distinguishes payment and procedure dates and can link a split to a procedure. Payment-split fields. Those fields support asking for a traceable service-and-payment file; they do not prove that the practice's existing allocations are complete or correct.
This entry focuses on elapsed time. Use the production and collections guide for the broader reconciliation. Here, the decision is whether a lower rate reflects less collection time or a difference that remains after the periods are aligned.
Compare two service groups at the same age
Consider two invented groups of completed services. Each group's services occur on its own starting day, called day zero. Group A has $50,000 of final adjusted charges. Group B has $80,000. The amounts do not change later. There are no refunds, unallocated receipts or payments for other work in the base case.
Every receipt in the table is linked to the selected services and counted once. The later review date occurs when A is 90 days old and B is 30 days old. Earlier snapshots preserve what A had collected by its own day 30. These are teaching assumptions, not expected payment speeds.
| Service group and elapsed age | Adjusted charges | Linked receipts by cutoff | Collection rate |
|---|---|---|---|
| A at day 30 | $50,000 | $40,000 | 80% |
| A at day 90 | $50,000 | $46,000 | 92% |
| B at day 30 | $80,000 | $64,000 | 80% |
At the later review date, A appears ahead by 12 percentage points: 92% versus 80%. But the groups have had different amounts of time. At the common day-30 cutoff, both are at 80%. The extra $6,000 collected for A after day 30 explains its higher later rate.
This does not prove that B will reach 92% by day 90. That outcome is still unknown. Nor does it prove that collection work is equally effective in every respect. It removes one timing mismatch so the next question can be asked on a clearer basis.
Retain the original day-30 evidence. Replacing it with A's current balance would lose the comparison. When services within a group occur on different dates, define how elapsed age will be measured before totaling them. A convenient calendar label is not automatically an equal observation window.
Test a real gap and a refund separately
First, change only B's receipts by day 30 from $64,000 to $56,000. Its rate becomes 70%, leaving a 10-percentage-point gap against A at the same age. Equal timing no longer explains that gap. It identifies a question for the payment review, not a proven cause or an eventual loss.
For a separate test, restore B's $64,000 receipts and assume a $4,000 refund tied to those services is paid by day 30. Define the numerator as receipts less that refund. Net receipts become $60,000 and the rate becomes 75%. The matched gap is five percentage points. Do not combine this refund with the first test's lower receipt amount.
Both tests preserve the $80,000 charge base. A real charge correction would require a separately labeled calculation. Do not change the denominator merely to recover a preferred percentage, and do not leave a known refund outside a numerator labeled net receipts.
Decide what the comparison can support
The worksheet helps decide which evidence is still needed. For an unresolved gap, ask about the included services, payment links, cutoff and known open items. Keep the cause unassigned until the relevant records support it. Neither a high rate nor a low rate alone establishes profit or practice value.
The hygiene and recall guide connects due care with completed work and receipts. The benchmark guide explains outside comparisons. An equal-age internal result is not a substitute for either review or a universal collection target.
For a sale, begin with seller-blind outreach and omit owner and practice identity, exact location and identifying financial or staff details. Obtain an NDA before releasing identifying reports to an authorized buyer. Agree when billing staff need a limited briefing to reproduce the snapshots. Patient-level payment links require separate access review.
Keep supported results and open questions visible in the financing review or DSO discussion.
Summary
A collection rate needs a defined charge group and observation window. The base example's apparent 12-point gap disappears at equal age, while the independent tests create real differences at that same cutoff. Later collections remain unknown until observed. Schedule a confidential discussion about the evidence behind the comparison.
Frequently asked questions
Why does the base gap disappear at equal age?
A has collected 92% by day 90 but only 80% by day 30. B is also at 80% at day 30. The original comparison gave A more time.
Does B therefore reach 92% by day 90?
No. Its later outcome is not supplied or predicted. Equal-age comparison removes one mismatch without proving eventual payment.
What does the lower-receipt test show?
B receives $56,000 against $80,000 of charges by day 30, giving 70%. That is ten percentage points below A at the same age, with the cause still unresolved.
How is the separate refund test calculated?
Restore B’s $64,000 receipts, then subtract the stated $4,000 refund. Net receipts of $60,000 divided by $80,000 give 75%.
