Where Insurance Claims Go After You Submit Them

Every medical practice bills insurance. Every practice has an “aging report” (a running list of unpaid balances, oldest first). And almost no practice can answer the question that actually matters: for every dollar we billed, where is that dollar right now, and who is sitting on it? Knowing where insurance claims go after submit is how you answer it.

This is one piece of a wider gap covered in revenue oversight, the daily job of watching every step between care delivered and cash in the bank.

The cash problem underneath the reporting problem

A medical practice pays its bills in cash on a schedule it does not control. Clinicians get paid every two weeks. Rent, software, malpractice insurance, all monthly, all fixed. But the revenue side runs on the insurance carriers’ schedule: the practice delivers care today, submits the claim this week, and gets paid whenever the carrier decides, thirty, sixty, ninety days later, or never.

The practice is effectively lending money to insurance companies every single day it operates, interest free, and payroll does not wait for the loan to be repaid. The clock that measures this gap is cash conversion, and the standard version of it starts counting too late.

That timing gap is survivable when it is stable. It stops being survivable when it widens. Growth makes it worse, not better: every new clinician and every new market means more payroll now against more receivables later. Revenue on paper keeps climbing while the bank account keeps tightening, which is the specific kind of squeeze that makes an owner start asking hard questions, because it is how healthy-looking practices die.

And claims differ from ordinary slow receivables in one brutal way: this money expires. Insurance contracts set filing and appeal deadlines, commonly 90 to 180 days. A claim that sits unresolved past the deadline becomes a permanent loss, converted quietly into a write-off that no one ever has to explain.

The investigation

Here is what a full claims-flow investigation at one growing practice turned up. Those carriers are its payers, the insurance companies that owe it. The finance team had bank statements and an accounting system. The billing team had the practice management system.

Nobody had the picture in between. In practices like this, owners feel the timing gap widen without being able to name it, and nobody can see which carriers, which months, or why.

Before we go further, four terms, so a non-biller can read the rest without stopping:

A claim is the bill for one patient visit. A claim carries one to three charges, the individual services performed. A remittance (the electronic version is called an ERA) is the report an insurance carrier sends back explaining what it paid and why.

And a write-off is a balance the practice removes from its books. Under a contract, that is the discount the insurance agreement requires. Outside a contract, it is a balance the practice gave up on.

Here is what the claims data showed when we finally lined it all up.

First, the big picture nobody had seen

Across the period, a large share of what the practice billed came back as cash, a similar share was written off under its contracts, and the rest was still outstanding or owed by patients.

Two numbers in that paragraph changed the executive conversation. First: of every billed dollar that had finished processing, less than half became cash. That is the honest scorecard, and no standard report showed it.

Second: more than half of what was outstanding was more than 90 days old, which is the slice where money actually dies. Insurance contracts set filing deadlines after which a claim becomes legally unpayable.

So when the owners saw the first cut of this data, the reaction was not curiosity. It was urgency on three levels. Cash they had already earned was stuck at nameable carriers for fixable reasons, some of it was weeks from expiring permanently, and the problem’s next stop was the operating account. That is why this kind of finding tends to become a standing weekly review.

With the big picture established, the problems fell out one by one.

What carrier-level visibility actually looks like

Before the problem list, here is the level of detail this produces. The ten rows below are an illustration, not any practice’s file. The dollar columns are left out on purpose; in a real view every row also carries what was billed, paid, written off, and still owed, plus a month-by-month history behind each one:

Read down that last column and notice what a practice-wide average would have hidden. Carriers A through D, the bulk of the billing, are fine.

The problems are concentrated in F through J, and each one has a different disease: F broke mid-year, G and H are enrollment failures, I is a speed problem, J is a surrender problem. One blended “days in AR” (accounts receivable, the money owed to the practice) number would have averaged all of this into mediocrity and pointed at nobody.

And every row opens up. Behind carrier F sits a month-by-month grid showing exactly when the payment rate fell off a cliff. It shows how many claims and dollars are stuck in each aging bucket, the date of its last payment, and the date of its last electronic remittance. That is the resolution at which a conversation with a payer rep changes from opinion to evidence.

The nine problems hiding in the data

1. Carriers that never answered at all

More than 30 carriers had been billed for months and had never responded. No payment, no denial (a refusal to pay), not even a single remittance. Silence.

When a practice grows into new markets, insurer enrollment paperwork rarely keeps up, and claims can go out for months to plans that never answer. The practice had grown; its payer enrollment paperwork had not kept up. And behind part of the silence sat the harder version of the same failure: no EDI enrollment at all, the electronic connection a carrier requires before it will accept a claim.

Those claims were going out on schedule and getting blocked at the door. Nothing entered adjudication (the carrier’s review of a claim), no rejection came back to say so, and the filing-deadline clock was running on every one.

An aging report shows these balances as “old AR.” It cannot show that the carrier has never once engaged, which is a different problem with a different fix and a hard deadline.

2. The carrier that broke

One large carrier paid steadily for a year, then its payment rate on newly submitted claims fell off a cliff while claims kept flowing to it every week.

A break like this hides for months, because each claim looks in process and the carrier keeps sending the occasional small check.

Trend the data by the month claims were submitted and the break is a cliff you can date to within a few weeks. That date is everything. It converts a vague “why is AR up?” meeting into a specific question for the payer rep: what changed that month: contract, credentialing (approval to bill a carrier), claim format, or policy?

3. Carriers that went quiet

Different from broken: these carriers paid normally, then stopped entirely while the practice kept billing them. We found more than a dozen. Each had a precise last-payment date, which matters, because the causes are mundane and fixable: a credentialing lapse, a bank-account or address change that broke the payment path, a hold nobody escalated.

The fix starts with a phone call, but only if someone knows which carriers to call and can open with the exact date the payments stopped.

4. Carriers that were written off instead of collected

The sneakiest finding. A handful of carriers showed nearly clean aging, almost nothing outstanding. Healthy, right?

No. For each of them, more than half of everything ever billed had been written off, with almost no cash ever received. The extreme case looks like a carrier with nearly everything written off and nothing collected, and only a side-by-side view shows it.

Write-offs make aging look clean. That is precisely the danger. An erased balance disappears from every report a billing team runs, so a practice can surrender real money while every dashboard stays green.

The only way to catch it is to put written-off dollars on the same page as paid dollars, carrier by carrier, and ask of each: was that discount contractual, or was it a quiet defeat? We have watched this species of problem before, in a category nobody questions.

5. Payments typed in by hand

Fewer than one in five carriers had ever sent an electronic remittance. The rest paid money but never sent one, so every one of those payments was posted into the billing system by hand.

The headline case: one of the practice’s largest carriers, zero electronic remittances, ever. Every check keyed in by hand, for want of a single ERA enrollment form at the clearinghouse (the service that routes claims to insurers).

Manual posting costs more than labor. It adds lag, typos, and reconciliation risk, and it stays invisible because no report shows “how this payment arrived.”

6. “Paid” claims with no money in them

One carrier showed a long run of charges marked paid, with a paid total of $0.00. A common posting habit records denials and contract adjustments as zero-dollar payments. Every “percent of claims paid” metric the practice looked at was quietly inflated by entries like these.

If your reporting counts a zero-dollar posting as “paid,” your paid rate is fiction. You have to count paid-with-money separately from paid-on-paper. It is the same lesson as the clean claim rate that lies: a metric is only as honest as what it counts.

7. The aging clock that lies

At a group of carriers, payments routinely arrived before the most recent submission date on the claim. Read that again: paid before submitted. It means claims were being sent again after a payment nobody recorded, or resubmitted over and over during disputes, and each resubmission resets the claim’s official age.

The consequence is worth sitting with. A claim that has been fought over for five months can appear in the 0-to-30-day bucket looking fresh. Whatever your aging report says, the truth is older. In this practice’s case, the “under 60 days” buckets were understated, which had been hiding how stale the disputes at the worst carriers really were.

8. The slow leak

Some carriers were not broken, just drifting: average days-to-payment creeping up month after month, balances sliding from the 30-day bucket into the 60s and 90s. Any single month looked acceptable. The twelve-month trend did not.

Two carriers held a large share of the slow-aging balances between them. State prompt-pay laws cap how long an insurer may take to pay a clean claim, and a documented drift past those limits is a negotiating card a practice rarely knows it holds.

9. Posted is not deposited

Everything above lives inside the practice management system. The final problem lives between systems. A payment posted in the billing system is a keystroke. Money is a bank deposit, and the accounting system is a third, separate record.

Until someone matches all three, carrier by carrier and month by month, two ugly scenarios stay invisible: cash that arrived but was never posted, and postings for cash that never actually landed. That three-way match is tedious by hand and nearly automatic once the carrier-level data exists, and it is the single control a CFO cares most about.

Four of the nine were never billing problems

Look again at which problems carried the money. Problems 1, 3, 5, and 6 are configuration and enrollment work, not claims work. When a practice grows into new states, payer and EDI enrollments can lag behind, and submitted claims have nowhere to land. ERA enrollment forms were never filed at the clearinghouse. Credentialing and payment paths lapsed without an alert. Posting conventions were set once and never revisited.

The billing team was doing its job, working the claims in front of it. Setup work like this has no queue and no owner, because everyone assumes it ended at go-live. It does not end.

Every new state, every new carrier, and every new clinician reopens it, and this practice had been growing fast. The claims were fine. The pipes they traveled through were never fully connected, and no report anyone ran was pointed at the pipes.

Why the practice’s reports never showed any of this

None of these problems is exotic, and none required wrongdoing. They persist because of how standard reporting works.

The aging report has no memory. It photographs balances at a moment in time. A carrier that broke mid-year and a carrier that was always mediocre look identical in a photograph; only the film shows the difference.

Write-offs remove evidence. Every standard report is organized around open balances, and a write-off deletes the balance from view. Clean aging is ambiguous: it means either well-collected or quietly surrendered, and no snapshot can tell you which.

Averages bury outliers. Practice-wide numbers blend every carrier into one figure. The problems live in the twenty worst carriers, and the average smooths them out of sight.

And the money trail crosses three systems that do not talk: billing, bank, accounting. The gap between them is where problems survive the longest.

What it took to see it

Nothing above required new software on day one. It required assembling data the practice already owned into one carrier-level view: what was sent, what was paid, what was written off, what is still open. That view runs in counts and dollars, by the month the claims went out, for every carrier, with every claim traced through to its outcome.

On top of that view, each of the nine problems becomes a simple, nameable test with a plain-language verdict. Each verdict reads the way an operator talks: “This carrier has never responded to us. Confirm we are enrolled before the filing deadline.”

“This carrier broke on a specific date; here is the before and after.” “This carrier pays you well and your staff types in every payment; one enrollment form fixes it.”

One design constraint mattered as much as the analytics: everything is carrier-level aggregate. No patient names, no dates of birth, no identifiers of any kind. The finance team, the FP&A analyst, an outside advisor, all of them can work the entire problem without ever touching protected health information.

The oversight layer

It is worth being precise about what this layer is, because owners hear “revenue cycle” and assume it means more software for the billing department. It never enters the billing department’s workflow. Your EMR and practice management system are where the work happens: scheduling, documentation, claim submission, payment posting.

Your billing team lives inside that system all day, working one claim at a time, and both are doing their jobs. The operator’s questions sit at a different altitude: is the whole machine working, where is it quietly failing, and what gets fixed first?

This sits on top of that machine, the way financial controls sit on top of bookkeeping. It does not touch a single claim. It watches what the system already recorded, and every finding lands as a ranked action list with an owner attached.

Priority one, the broken carrier: payer contracting takes the before-and-after to the rep this week. Priority two, the plans that never respond: the billing manager verifies enrollment before filing deadlines hit. Priority three, the large carrier posted by hand: revenue cycle ops files one ERA enrollment form.

Each item has a dollar figure, a named owner, and a specific first move, which is the difference between a report that gets read and a report that gets executed.

The billing team keeps working claims, the way it always has. The owner finally gets to manage the system the claims flow through, with the same discipline they already apply to P&L and payroll.

Who runs the billing does not change what the layer does. In-house, it is how leadership sees the whole machine instead of a queue. Outsourced, it gives the practice and its billing service the same carrier-level picture, drawn from the practice’s own system, so the monthly conversation runs on evidence.

Here is the carrier that has never paid us, here is the one that needs a single ERA enrollment form, and here is where the write-offs deserve a second look. Findings arrive as shared work items with the data attached, and the service working the claims is the first to benefit from knowing exactly where to aim.

It matters most at the moment of transition. Practices switch billing arrangements, or bring billing in-house, at exactly the moment when the least is known: open claims fall into the seam between teams, and the incoming team inherits balances it did not create.

Run the funnel before the handoff and both sides cross over with a complete picture. That picture shows exactly where every carrier stands, which balances are real and which are already lost. It shows what corrective actions transfer on day one, and gives a baseline to measure the new arrangement against ninety days later. The transition stops being a leap of faith and becomes a measured handover.

And it scales past a single practice. For a PE firm or an MSO holding a portfolio, the same funnel runs on every practice and rolls up. It shows where each one stands, where the breakdowns are, and which practices share the same broken payer.

It works as diligence on a practice you are about to buy, as a 100-day baseline on one you just bought, and as the standing operating review on the ones you hold. One practice or twenty, the answer arrives in the same form: a carrier table, a ranked action list, and a named owner for every item.

The point

This practice believed it had one problem: AR was creeping up. It actually had nine, wearing a trench coat: enrollment failures with deadlines attached, a broken carrier, silent carriers, and write-off leakage. Then manual posting, inflated paid metrics, an understated aging report, slow-pay drift, and an unverified gap between posted and deposited.

Every one was findable in data the practice already owned, and every one had been invisible for more than a year. Once the data was assembled, each came with a specific next action and a name attached.

And the funnel did not run once. It runs every week now, on fresh data, so the next carrier that breaks gets caught within weeks instead of surfacing a year later as a cash crunch. Finding the nine was the first step. Watching for the tenth is what keeps them fixed.

This is not for every practice. A group with a handful of carriers, a monthly three-way reconciliation, and numbers it trusts already has the control in place. It is for the practice that grew, added states and carriers and clinicians, and never rewired the oversight to match.
