How to Recover Aged A/R: A Practical Recovery Workflow

The single most expensive habit in aged-A/R work is treating the aging bucket as the prediction. It is not. Four things actually determine whether an old claim can still be collected, and none of them is the date:

• Is the filing clock still open? A claim past the payer's timely-filing limit with no documented good-cause exception is generally dead on arrival, whatever its balance. This is the first question, not the last.
• Are appeal rights still live? A claim that reached adjudication and was denied carries appeal rights and a deadline that runs from the remittance date. A claim returned as unprocessable before adjudication was never denied and carries no appeal rights — it has to be corrected and resubmitted, against the original filing clock.
• Is the denial cause correctable, and do you have the document that corrects it? “Missing modifier” with the operative note in hand is a different job from “not medically necessary” with nothing new to submit.
• Does the balance justify the work? Every touch costs staff time. A claim can be perfectly appealable and still not be worth appealing.

Sort on those four and the aging report stops being a wall of old claims and becomes a short work list. Sort on age alone and you spend the month on the oldest claims, which are the ones most likely to have failed the first two tests.

Not all aged claims deserve equal attention. Prioritize by filing-deadline proximity first (a claim about to expire is the only genuinely urgent item on the report), then by balance, then by whether the denial reason is correctable with a document you already hold. Payers with a known slow-payment or repeat-denial pattern in your own remittance history deserve a standing follow-up cadence rather than ad-hoc calls. This targeted approach concentrates staff hours where they can still change an outcome.

Successful A/R recovery requires systematic accounts receivable follow-up including contacting payers by phone and portal for status updates, resubmitting claims with corrected information, filing appeals with supporting documentation, escalating to payer representatives when standard channels fail, and documenting every contact for future reference. Consistent, documented follow-up is the key to recovering aged balances.

The best approach to aged A/R is preventing it in the first place. That means submitting clean claims promptly after the encounter, working denials as soon as the remittance posts rather than at month end, following up on unpaid claims on a fixed cadence instead of when someone notices, and tracking days in A/R as a standing metric alongside the share of A/R over 120 days. The AAFP's published guidance target for days in A/R is below 50 days at minimum, with 30 to 40 preferable; it publishes no target for the percentage of A/R sitting past 120 days, and neither do we — track your own trend line instead of a borrowed threshold.

Every aged-A/R article on the internet carries a version of the same table: 0–30 days collects at 95–98%, 31–60 at 80–85%, 61–90 at 60–70%, 91–120 at 35–50%, over 120 below 30%. It is usually attributed to MGMA or HFMA. This page used to carry it too, and it has been removed.

The reason is that the attribution does not survive checking. MGMA's practice-performance values are licensed and are not published free of charge. HFMA's MAP Keys publish standardized metric definitions, not target values. The curve itself traces to secondary articles that state no population, no sample size, no data year and no definition of “collected” — which means there is no way to know whether a bucket figure refers to claim counts or dollars, to a single specialty or all of them, or to one payer mix or another. A number you cannot define is a number you cannot plan against.

What is safe to say instead. Old claims are harder to collect than new ones — that much is mechanical, because filing limits expire, appeal windows close, staff turnover removes the person who remembers the case, and patient contact details go stale. But how much harder, for your practice, is an empirical question your own remittance history answers better than any published curve. Pull twelve months of recoveries, tag each by the aging bucket the claim was in when work started, and you have a recovery rate that is actually about your payers, your specialty and your documentation. That number is worth managing to. A borrowed one is not.

The one published figure this page relies on is the AAFP's days-in-A/R guidance quoted in the introduction, and the AAFP states it as practice-management advice with no population, sample or data year behind it.

Effective aged-A/R recovery is a triage problem. The worked example below is illustrative — the balances, payers and dates are invented to show the sort, not drawn from any client file — but the columns are the ones that decide the disposition. Run your own legacy A/R through the same six columns before anyone picks up a phone.

The pattern to notice: the oldest claim on the list (E, 260 days) is the one to stop working, and the youngest (A, 82 days) is the most urgent. Deadline proximity outranks age, appeal rights outrank balance, and “do I have the document that fixes this?” outranks everything except the clock.

On cost to work. Every claim on the list costs staff minutes to touch, and below some balance the minutes exceed the recovery. Calculate that threshold from your own fully-loaded hourly cost and your own average touches-per-resolution rather than importing a rule of thumb; the answer differs by an order of magnitude between a practice that resolves most claims on the first portal check and one that averages three phone calls.

The mistake practices make: working the aging report chronologically, oldest first. That sorts the work list in almost exactly the wrong order.
