The MedsIT Nexus Approach to Denial Management and AR Recovery

Ask a practice manager how much money is sitting in their accounts receivable and most can answer within a few thousand dollars. Ask how much of it is realistically collectible and the room usually goes quiet.

That gap is the whole problem. Aged AR is treated as one number on a report when it’s really several very different piles of money: claims that will pay on their own, claims that need a phone call, claims that need a corrected submission, claims that were underpaid and nobody noticed, and claims that are dead and should have been written off months ago. Working them as though they’re the same thing is why AR recovery efforts so often produce a lot of activity and very little cash.

Here’s how MedsIT Nexus works through it, and why the sequence matters more than the effort.

Reading the AR aging report properly

An AR aging report review starts by splitting the balance into buckets — 30, 60, 90, and 120-plus days — and then splitting it again by payer.

The buckets tell you about process. A balance concentrated in 0–30 days is normal; claims take time to adjudicate. A growing 90-plus bucket means something upstream broke, and the age tells you roughly when. If the 120-plus pile started swelling four months ago, something changed four months ago: a credentialing lapse, a payer policy update, a staff departure, a new authorization requirement nobody caught.

The payer split tells you where to look. One commercial plan sitting at 90 days while everything else clears at 30 is a specific, findable problem. It’s usually a claims edit, an enrollment issue, or a payer that’s changed a submission requirement without much warning.

Most practices never do the second split. It’s the one that turns an aging report from a status update into a diagnosis.

Prioritizing by dollar value and deadline, not by whatever’s on top

The instinct when facing a large AR pile is to start at the beginning and work down the list. That’s the least productive order available.

AR prioritization should weigh three things: the dollar value of the claim, its age relative to the payer’s timely filing limit, and whether the balance is likely recoverable at all. A $2,400 claim that hits its filing deadline in three weeks outranks fifteen $60 claims that have months left. A claim already past the deadline, however large, belongs in a write-off review rather than a follow-up queue — chasing it costs staff time you can’t recover either.

Filing windows vary enough to matter. Medicare generally allows 12 months; some commercial payers allow 90 days from date of service. Appeal windows are usually shorter still and run from the date of the remittance, not the date of service, which is a distinction that costs practices appeals they would have won.

Sorting the queue this way changes what a follow-up day produces. The same eight hours of work recovers substantially more when the highest-value, closest-to-expiry claims are handled first.

Claims status follow-up before the claim goes quiet

Unpaid claims resolution gets harder the longer a claim sits untouched. Checking claim status at set intervals, rather than waiting for a remittance that may never arrive, catches the ones that were never adjudicated at all. It’s repetitive work, and it’s the bulk of what accounts receivable services actually consist of day to day — not dramatic recoveries, but a queue worked on schedule so claims don’t go quiet long enough to expire.

 

Some of them were rejected at the clearinghouse and never reached the payer. Some were received and are pending additional information the payer requested from the patient. Some are simply lost, which happens more often than payers like to acknowledge.

Electronic status checks handle most of the volume. Payer follow-up calls are still necessary for the rest, and the difference between a productive call and a wasted one is preparation: having the claim number, the exact denial or pend reason, the relevant documentation, and a specific question ready. Calling to ask “what’s the status” invites the answer “still processing.” Calling to ask why a specific claim pended on a specific date with a specific code produces something actionable.

Denial follow-up and appeals, sorted by cause

Denial management fails when denials are worked one at a time in arrival order. Sorted by reason code, the same denials become a much smaller problem.

In most practices a handful of causes account for the majority of denied claims: eligibility and registration errors, missing authorization, coding specificity, coordination of benefits, and non-covered services. Grouping them shows where the process broke, and fixing the process shrinks next quarter’s volume — which is the only version of denial management that ever gets ahead.

Individual claims still need handling. Corrected claim resubmission is right when the original had an error — wrong modifier, wrong place of service, missing information. An appeal is right when the claim was correct and the payer’s decision was wrong, and it needs supporting clinical documentation, not just a resubmission of the same data. Rebilling an identical claim after a medical necessity denial produces an identical denial, and burns time inside the appeal window.

Underpayments: the money nobody looks for

Underpayment identification is the least-performed task in the entire cycle, because underpaid claims don’t look like problems. They post as paid, they close, and the balance clears.

The only way to find them is to compare payments against contracted rates. A payer reimbursing consistently below contract on a common CPT code can drain a practice for months without generating a single denial or a single phone call. It shows up nowhere in a denial report and nowhere in an aging report.

Spot-checking remittances against the fee schedule monthly, by payer and by high-volume code, catches it. When a pattern appears, it becomes a contract conversation with evidence behind it rather than a vague complaint about reimbursement rates.

Write-off review as prevention, not cleanup

Write-offs are necessary. Unexamined write-offs are a leak.

Every adjustment posted as a contractual write-off should be verifiable against the contract. Every balance written off as uncollectible should have a reason attached — past filing, appeal exhausted, patient bankruptcy, small balance policy. When those reasons get categorized rather than lumped together, the report becomes a map of where revenue is being lost before it’s ever collected.

A rising volume of timely-filing write-offs, for example, isn’t a collections problem at all. It’s a follow-up capacity problem, and no amount of AR effort fixes it downstream.

Patient balances and escalation

Patient statement follow-up runs on a different clock than insurance AR and responds to different things. A clear statement that shows what insurance paid, what was adjusted, and what remains generates fewer confused phone calls than a line-item printout. An estimate given at the time of service does more than either.

A collections escalation workflow should be defined in advance: statement intervals, at what point a call replaces a letter, when a payment plan is offered, and the threshold at which an account moves to an outside agency. Written down, it gets applied consistently. Left to judgment, small balances linger and large ones get escalated late.

The number that tells you it’s working

First-pass resolution rate — the share of claims paid correctly on the first submission — is the single most useful measure of a revenue cycle, because it’s the only one that describes prevention rather than recovery.

AR recovery work is remedial by definition. It’s necessary, and a good AR effort brings in real money, but every claim in that queue represents something that should have gone out clean. When first-pass resolution climbs, aged AR shrinks on its own, and the recovery work gets smaller because there’s less to recover.

That’s the outcome MedsIT Nexus works toward with medical billing solutions built around prevention: clear the backlog, then close the gaps that created it.

If you only do one thing

Pull your AR aging report, filter to balances over 90 days, and sort by dollar value. Look at the top twenty claims.

Some of them will surprise you — large balances sitting unworked for reasons nobody remembers. Those twenty claims will tell you more about the state of your accounts receivable than any summary report, and a few of them are probably still collectible if someone picks up the phone this month.
