Can I Force My Billing Company to File Old Claims?

What Actually Resolves Claims Your Vendor Refuses to File

The goal is simple: every aged claim submitted and answered, every valid appeal worked, and every true write-off documented, so nothing sits unbilled, undenied, and undecided. Here is what does that, move by move.

1. Inventory Every Aged and Inherited Claim

Before you argue with anyone, build the list. A revenue-cycle specialist pulls every claim past or near timely filing, including the ones inherited from a prior billing company that never got worked, and records the date of service, the payer, the filing deadline, and the current status. Most practices do not actually know how many aged claims are sitting in limbo until someone counts them. The inventory tells you which claims still have a live filing window, which are past it, and which need to be submitted for denial to open up any next step at all.

2. Submit the Aged Claims to Get a Formal Denial on the Record

Industry guidance is to file the claim even when you expect it to be denied, because the denial is what opens every path after it. A revenue-cycle specialist submits each aged claim so the payer issues a formal timely-filing denial, which is the document you need to appeal, to document a write-off, or to bill the patient where the rules allow. A claim your vendor left unsubmitted has none of those paths open; a claim that has been submitted and denied has all of them. This step is the whole point, and it is the one the percentage-fee vendor would not do.

3. Work the Appeals That Have a Real Basis

Not every timely-filing denial is a dead end. Where there is a valid reason for the delay, proof the payer had the wrong address, a coverage that was discovered late, or a documented submission that was rejected in error, a revenue-cycle specialist files a detailed appeal with the supporting records attached. This is where the systems you already run, whether NextGen, Cerner, or AdvancedMD, let the specialist pull the acceptance reports, the coverage history, and the documentation that turns a defensible late claim into a paid one instead of a write-off.

4. Document a Clean Write-Off Where No Appeal Exists

When a claim is genuinely past filing with no valid delay reason, the answer is not to leave it in limbo, it is to close it cleanly. A revenue-cycle specialist records the formal denial, notes why no appeal applies, and processes the write-off with a documented reason, so your books are accurate and your audit trail is complete. A documented write-off is a decision; an unsubmitted claim is an open question that never closes, distorts your aging report, and leaves you exposed if anyone ever asks why the money was never pursued.

5. Hand Aged-Claim Resolution to a Dedicated Outsourced Team

Practices that stop leaving abandoned claims in limbo do it by handing aged-claim resolution to a dedicated outsourced team: credentialed remote specialists who inventory, submit, appeal, and document every claim the percentage-fee vendor would not touch, live in 1 to 2 weeks. The stack of unbilled, undenied, undecided claims drops toward zero inside the first weeks, a trained backup covers the queue, and your aging report finally tells the truth. Below is what it sounds like when nobody owns this yet, in practice teams’ own words.

Why This Keeps Happening

If a claim just needs to be filed, why would a billing company refuse to file it? Because their incentive points the other way. Most billing companies charge a percentage of collections, so their revenue comes only from claims that actually pay. A claim expected to deny for timely filing is a submission with zero recovery attached, which means it is pure labor cost to them and pure loss on their side of the ledger. The refusal is not laziness; it is the fee model working exactly as designed, and it means the claims least likely to pay are the ones your vendor is least willing to touch, even though those are the ones you most need submitted to reach any resolution.

Now add the contract gap. Vendor service agreements are typically written around ongoing, current claims, and they rarely specify any obligation for aged claims or the backlog inherited when you switched from a prior billing company. So when you ask them to submit old surgical cases for denial, there is often no clause that requires it, and no clause in the agreement to force it. Whether you can compel them at all depends on the exact language you signed, which is why the practical answer is not to wait on that fight but to get the claims submitted through a team that will. This is exactly the gap dedicated accounts-receivable follow-up is built to close.

And the cost of leaving them in limbo is larger than the claims themselves. Industry guidance is clear that you should file a claim even when you expect a denial, because the formal denial is what opens the appeal, the documented write-off, or patient billing where the rules allow. A claim that is never submitted has none of those paths: you cannot appeal a denial you never received, and you cannot cleanly close what was never billed. Meanwhile the unresolved balances inflate your days in AR, distort your aging report, and leave an audit exposure, because there is no documented reason the money was never pursued. The AAPC billing community discusses exactly this scenario, and the guidance is consistent: submit for the denial, then decide.

Most groups have already tried the obvious fixes before they talk to anyone. Each one fails the same way: the work lands back on the practice. The pattern, in one table:

The Solution

So what does “someone whose whole job it is” actually look like on a stack of abandoned claims? A dedicated remote revenue-cycle specialist first builds the inventory: every aged and inherited claim, with its date of service, payer, filing deadline, and status, so you finally know exactly what is sitting in limbo. Then the specialist submits each one so the payer issues a formal denial, the single step your percentage-fee vendor would not take and the one that opens every path after it. That submission-for-denial work is the whole point of pairing a specialist with aged AR calling that chases every claim to a resolution.

Then comes the part that separates the collectible from the closable. Where a claim has a valid delay reason, a wrong address on file, a late-discovered coverage, a documented submission rejected in error, the specialist files a detailed appeal with the acceptance reports and records attached, and works it to payment. Where no valid reason exists, the specialist records the formal denial, notes why no appeal applies, and processes a documented write-off, so nothing is left as an open question. Your books stop lying about what you are owed, and every aged claim becomes a decision instead of a gap.

Behind all of it, the AI takes the first pass and a credentialed human verifies. Automation tracks claim status, flags the filing deadlines, and keeps the aging report current; the specialist owns the submission strategy, the appeal argument, and the write-off decision. For the denials that do have a fighting basis, the same team extends into denial management and appeal drafting, so a timely-filing denial with a real defense becomes a worked appeal instead of a resigned write-off.

Who Actually Does This Work

Fair question: why would an outsourced team work your abandoned claims when your own billing vendor would not? Because our model does not punish us for submitting a claim that might not pay. The people working your aged claims on our side are credentialed virtual medical professionals: overseas-trained physicians, US-licensed nurses and pharmacists, and PharmDs, all trained specifically in US revenue-cycle and denial workflows, on a dedicated model rather than a percentage of collections. They are not skipping the zero-recovery claims to protect a fee; submitting, appealing, and documenting every aged claim is the job. When a surgical case needs a formal denial before anything else can happen, the person on it files it, because that is exactly what they are there to do.

We are not a call center. We are a clinical operations partner, a healthcare BPO built on dedicated virtual staff: 500+ credentialed professionals, 24/7 coverage, and the AI first-pass plus human-verify workflow you just read about running behind every one of them. Your virtual revenue-cycle specialist works inside your books as an extension of your own team, not a percentage-fee vendor. A typical practice is live in 1 to 2 weeks, at up to 70% below the cost of hiring locally. And nobody on our side calls in sick without a trained backup already inside your workflow, so your aged-claim backlog keeps getting worked whether or not any one person is at their desk.

And the security piece your compliance officer will ask about: we are audited to SOC 2 Type II with zero exceptions and certified for HITRUST, ISO/IEC 27001:2022, HIPAA, and GDPR, with zero breaches in eight years. Every workstation runs inside a secure enclave on US-based servers, with screen captures and downloads blocked by policy, so PHI never sits on someone’s home laptop. Every client account carries a $5M E&O and cyber liability policy and a BAA signed before any work starts; the full detail lives in our HIPAA and security posture.

Put the routine and the people together, and a specific list of things simply stops happening.

How We Permanently Fix the Process

A specialist alone is not the fix, and neither is a new vendor alone. The fix is a documented aged-claim protocol: how the backlog is inventoried, which claims get submitted for denial, which denials get appealed and on what basis, and how the rest get written off with a documented reason. Before we work a single claim for a new practice, we pull your full aged and inherited AR, map the filing deadlines and payer rules against it, and build the resolution path for every claim, so nothing is left sitting because it was never anyone’s clear job.

From there the protocol becomes a living record rather than a backlog nobody owns. It captures which claims were submitted and denied, which appeals were filed and won, which write-offs were documented and why, so your aging report stays honest and your audit trail stays complete. It is written down, kept current, and owned by the team. When your specialist is out, a trained backup works the same protocol the same way, so aged claims keep moving to resolution instead of piling back up into a new limbo.

That is the difference between arguing with this vendor and fixing the process for good, and it is what a dedicated revenue cycle management partner actually buys you. A billing company refusing the unprofitable claims used to mean a growing stack of undecided AR. Under this model every aged claim gets submitted, appealed, or documented, the playbook stays, the backup steps in, and the claims your old vendor abandoned stop being the hole in your books.

The Whole Thing in Four Sentences

Billing companies refuse to file old claims because their percentage-fee economics make a zero-recovery submission pure cost, and the service agreement almost never obligated them to work aged or inherited claims. Arguing the contract, waiting them out, or leaving the claims as open receivables all fail the same way, because none of them get the claim submitted, and an unsubmitted claim can be neither appealed nor cleanly written off. The fix is to inventory every aged claim, submit each one for a formal denial, work the appeals with a valid basis, and document a clean write-off on the rest. A general surgery practice with three cases its vendor refused to file runs exactly this model with us today, names withheld, no patient data shown.

If you want to check us out before talking to anyone: our security posture is independently auditable, we are an MGMA 2026 Corporate Member, and 800+ providers run back office work with us.

Ready to resolve your abandoned claims? Try us risk free: two weeks, your real aged and inherited AR, credentialed specialists submitting, appealing, and documenting every claim your old vendor would not touch, and if it does not earn the handoff, you walk away. From here down is the sales part, and it is short: here is exactly what it costs.
