90 days
Timely filing closes the door
Some plans set timely filing as short as 90 days. Past that deadline you permanently lose the right to appeal and the balance becomes a write-off — no matter how valid the claim was.
Revenue leaking through billing gaps
This is not money you have to go earn. It is production you already delivered, sitting in an aging report that nobody has time to work.

01 · The problem
The gap between what you produced and what you collected.
Every practice tracks production. Far fewer track the distance between production and deposit — which is where the leak lives, because it never shows up as a bad day.
A healthy practice collects 98% or more of what it is contractually owed. Below 95%, revenue is being left behind through unresolved patient balances, billing errors, insurer underpayments and administrative write-offs that were never challenged. Industry estimates put the exposure from weak revenue cycle management at 10 to 20% of practice revenue.
The leak is rarely one broken thing. It is six small ones running in parallel, each of them individually forgivable on any given Tuesday. Treatment gets delivered and never coded out. A claim goes out without the attachment or the narrative it needed. A denial arrives and gets filed instead of worked. An insurer pays below the contracted fee and nobody compares it to the schedule. A patient balance ages quietly past the point where anyone is comfortable calling about it.
What makes it structural rather than occasional is that billing has no protected time. It is what the front desk does when the phones stop, and in a practice with a full schedule the phones do not stop. So the work is always deferred by one day, and the oldest claims are always the ones that get deferred again.
-
A
Unbilled and under-coded production
Procedures completed in the operatory that never make it onto a claim, or go out under a code that pays less than the work performed. This one is invisible by definition: there is no denial, no aging balance and no report that flags it.
-
B
Claims submitted incomplete
Roughly 30% of dental claims are initially rejected for missing information — an attachment, a narrative, a perio chart, a date of prior placement. Each one is a three-to-six week delay on money that was already earned.
-
C
Denials that are filed instead of appealed
Fewer than 1% of denied claims are appealed, yet 69% of contested claims are eventually paid. Practices are not losing these arguments with insurers. They are not having them.
-
D
Underpayments nobody checks
A payment that arrives looks like a closed claim. Unless someone reconciles the EOB against the contracted fee schedule, an insurer paying 8% below contract will keep doing it on every claim, indefinitely.
-
E
Patient balances left to age
The longer a balance sits, the less likely the patient is to recognise it, and the more uncomfortable the call becomes. Practices end up with a receivable they are emotionally unwilling to collect.
02 · What it costs
Uncollected revenue has an expiry date.
Unlike most business problems, this one gets permanently worse with time and cannot be recovered later. A claim has a shelf life, and it is shorter than most practices assume.
15–25%
Collectability collapses with age
On balances more than 90 days past due, practices typically recover only 15 to 25 cents on the dollar. The healthy benchmark is 30–40 days in AR, with under 3% sitting past 90.
10–20%
A margin-sized number
Poor revenue cycle management puts 10 to 20% of revenue at risk. On a practice producing $1.2M, the gap between a 95% and a 98% collection rate is roughly $36,000 a year in work you already did.
45+ days
You finance the insurer's float
Payroll, lab bills, supplies and rent leave on schedule whether or not collections arrive. Every extra week in AR is working capital the practice lends to the payer, interest-free.
First page
It shows up in your valuation
AR aging and net collection rate are the first two numbers a lender or an acquiring group reads. A bloated 90-day bucket is priced as a discount on the practice, not as a temporary backlog.
Compounding
The backlog defends itself
Every month of deferred billing pushes older claims further from collectability, which makes the report more discouraging to open, which defers it again. Backlogs do not sit still.
03 · The usual fix
Five habits that feel like billing management.
Each of these produces a sense of control. None of them produces a deposit.
Review the aging report every month
Why it stops short
Reading the report is not working the report. Visibility without a person assigned to each line produces an accurate description of the problem, once a month, with no change to the outcome.
Batch-submit claims at the end of the week
Why it stops short
Whatever is unfinished when Friday ends stays unfinished, and it is always the complicated claims — the ones needing narratives or attachments — that get left. Batching systematically defers the highest-value work.
Write off anything over 90 days to clean up the report
Why it stops short
This converts a collections problem into a permanent loss and then deletes the evidence. It also hides the trend, so the same volume rebuilds in the same bucket next quarter.
Hire a billing vendor paid on a percentage of collections
Why it stops short
It aligns the vendor with the easy money — clean claims that would have paid anyway. The old, contested, appealable AR is precisely where the effort is high and their margin is worst, so it stays exactly where it was.
Buy software that flags the problem claims
Why it stops short
A flag is not a phone call and a dashboard is not an appeal. Better instrumentation on an unstaffed process gives you a precise, real-time view of money you are still not collecting.
Billing does not fail for lack of information. It fails because no one has protected time to act on it.
04 · What Synktask does
Claims out clean, denials worked, AR under 30 days.
We run the revenue cycle as a standing operation rather than a task that survives on leftover time — and we bill per practice, not per collection.
Submitted the day the procedure is completed
Claims go out complete — attachments, narratives, supporting documentation — on the day of service rather than at the end of the week. Clean first submissions are the cheapest money in the cycle.
Denials appealed, not filed
Every denial is worked with a written appeal and tracked to resolution. Claims approaching a timely filing deadline are escalated first, because those are the only ones that expire.
AR worked oldest-first, every week
The aging report is a work queue, not a monthly reading. We hold AR under 30 days and keep the 90-day bucket where the benchmark says it should be — under 3%.
Payments reconciled against your fee schedule
Every EOB is checked against contracted rates so underpayments get caught and re-billed instead of quietly becoming your new normal.
A percentage-of-collections vendor earns most on the claims that were always going to pay. Billing per practice removes that incentive: the difficult, aged, appealable claims are worth exactly as much of our attention as the easy ones, because our fee does not move either way.
