A clean claim that nobody follows up on is still unpaid revenue. Most billing advice for small practices is about denials: code it right, attach the right documents, appeal what comes back. That matters, and we have written about it specialty by specialty. But a lot of money is lost somewhere quieter, in the gap between "claim submitted" and "payment received," where claims sit with no answer, partial payments go unquestioned and patient balances age without anyone owning them. That gap is medical billing accounts receivable, and it is a follow-up discipline problem as much as a coding problem.
This post is about the money side after a clean claim goes out: how AR ages, why each payer needs its own follow-up plan, how patient balances need a different, gentler cadence, and what a Filipino healthcare virtual assistant from the Philippines, trained for your specialty actually does each day to move cash in sooner. If you want the denial side, start with our medical billing VA guide by specialty.
Because submitting a claim is not the same as getting paid for it. Between those two moments, a claim can be lost at the clearinghouse, pended for more information, paid at the wrong rate, paid to the wrong provider number, or simply left unprocessed. None of those show up as a denial on day one. They show up as silence.
In many small outpatient practices, billing time goes to what is urgent: today's charges and this week's denials. Follow-up on claims that have not come back is the task that gets pushed to Friday, then to next month. Nobody decides to stop chasing a $180 claim. It just ages until the payer's filing or appeal window has closed and the money is gone.
That is why AR follow-up works best as its own job with its own worklist, not as whatever time is left after charge entry.
An AR aging report sorts every unpaid balance by how long it has been outstanding. The buckets are simple, but the work in each one is different:
| Bucket | What it usually means | What the follow-up looks like |
|---|---|---|
| 0 to 30 days | Normal processing time | Confirm the claim was accepted by the clearinghouse and the payer; fix rejections the same week |
| 31 to 60 days | Past the usual payment window | Check claim status in the payer portal or by phone; correct and resubmit anything stuck |
| 61 to 90 days | Something is wrong | Escalate: call the payer, document the reference number, request reprocessing, check the filing deadline |
| Over 90 days | At risk of becoming uncollectible | Work oldest and largest first, watch every filing and appeal deadline, flag write-off decisions to the practice |
The point of the buckets is not the report itself. It is that the follow-up cadence should change at each threshold. A claim at day 20 needs a quick acceptance check. A claim at day 75 needs a phone call today.
Because payers do not run on the same clock. Each one has its own typical processing time, its own portal and phone process, and its own deadlines for filing a claim and for disputing a payment. Medicare, for example, generally requires a claim to be filed within 12 months of the date of service. Commercial and Medicaid plans set their own limits, and many are shorter, sometimes much shorter, depending on the plan and your contract.
A dedicated AR assistant keeps a simple payer grid: how long each payer normally takes, how to check status with each one, and the filing and appeal windows that apply. Follow-up dates are set from that grid, so a claim never ages past a deadline just because nobody looked. It is unglamorous work, and it is exactly the work that gets skipped when billing is one more task on a busy front desk.
Patient responsibility, meaning deductibles, copays and coinsurance, is a different kind of AR. These are your patients, not a payer, so the follow-up has to be clear, polite and consistent: a statement after insurance pays, a reminder on a set schedule, and an easy way to ask questions or pay.
A billing VA can own that whole rhythm: sending statements on the practice's schedule, answering "why do I owe this?" calls by walking through the explanation of benefits, taking payments through the practice's own system, and setting up payment plans within the terms the practice approves. What the VA does not do is set financial policy. Write-offs, hardship adjustments and any decision to send an account to an outside collection agency stay with the practice.
The VA follows the codes and documentation the clinician provides. It never changes a code to get a claim paid, never makes coverage decisions and never decides what to write off. Payers sometimes request records or ask clinical questions; those go to the clinician. And it works inside your own billing system, under your access controls, whether the work comes from a local hire or an offshore team in the Philippines. For how that access is protected, see HIPAA compliance with a VA in the Philippines.
"A denial tells you something went wrong. Silence tells you nothing, which is why the claims nobody calls about are the ones most likely to be lost."
The short version
Why AR follow-up needs its own owner
The honest way to measure AR work is days in accounts receivable: your total outstanding AR divided by your average daily charges. It tells you how long, on average, it takes to turn a visit into money in the bank.
Here is a simple illustration. Say a practice bills an average of $2,000 a day and carries $90,000 in AR. That is 45 days in AR. If steady follow-up brings that down to 35 days, the AR balance at the same billing level drops to $70,000. The $20,000 difference is cash that arrives sooner instead of sitting with payers and patients. It is not new revenue; it is money you already earned, collected earlier, plus whatever would otherwise have aged past a deadline and been lost.
Those numbers are illustrative only, not a benchmark or a promise. Your own results depend on your payer mix, your specialty and how much AR is already old. The right first step is to pull your aging report and look at what is sitting past 60 days.
A Filipino specialty-trained healthcare virtual assistant from 3F Solutions is $9.00 an hour full-time (40 hours a week) or $10.50 an hour part-time (25 hours a week minimum), with no setup fees or long-term contracts. For the full breakdown, see what a Filipino healthcare VA actually costs.

Get Started →Accounts receivable (AR) is the money your practice has earned but not yet collected: claims sent to insurance that have not been paid, plus balances patients still owe after insurance. It is usually reported by age, in buckets such as 0 to 30, 31 to 60, 61 to 90 and over 90 days since the claim or statement went out, because the older a balance gets, the harder it usually is to collect.
A common approach is to check claim status once a claim passes the payer's usual processing time, often around 30 days for clean electronic claims, then follow up on a set rhythm in each aging bucket, with the most attention on anything past 60 days. The right cadence depends on each payer's timelines and on its timely filing and appeal windows, which differ by payer and contract, so the follow-up plan should be written per payer, not as one rule for all.
Yes. A billing virtual assistant can check claim status through payer portals and clearinghouse tools and call payer provider-service lines on the practice's behalf, using the practice's identifiers and the access the practice grants. Every call is documented on the claim with the date, the reference number and what the payer said. Some payers limit what they will discuss or require specific authorization, so the practice confirms each payer's rules during setup.
It can handle the administrative side: sending statements on the practice's schedule, answering balance questions, explaining what insurance paid, taking payments through the practice's own system and setting up payment plans within the terms the practice approves. The practice decides its financial policy, including write-offs, hardship adjustments and whether any account goes to an outside collection agency. The VA never makes those calls on its own.
Denial management deals with claims the payer has already rejected or denied: finding the reason, correcting the claim and resubmitting or appealing. AR follow-up starts earlier and covers more: every claim that has gone out but not been paid, including claims with no response at all, partial payments and patient balances. A claim can sit unpaid for months without ever being denied, which is why AR needs its own owner and its own daily worklist.
Sources and a note on the numbers: Medicare's claim filing limit is set out in 42 CFR 424.44 (time limits for filing claims). Commercial and Medicaid filing and appeal windows vary by plan, state and contract; check each payer's provider manual and your contract. The days-in-AR example is illustrative arithmetic, not a benchmark or a guarantee. A healthcare VA never chooses billing codes, makes coverage decisions, decides write-offs or signs on a provider's behalf.
