How to Recover Years-Old A/R Tied to Insurer Underpayments
Listen to this article A little known fact: even several-year-old A/R tied to insurer underpayments can be recovered. Healthcare providers leave millions on the table every year due to unresolved underpayments from insurers acting in bad faith. A common misunderstanding is that if an insurer underpayment wasn’t challenged within several months, or missed out on the No Surprises Act (NSA)’s Independent Dispute Resolution (IDR)’s limited timeframe, it is too late to revisit the A/R. These severe underpayments strongly impact healthcare finances. Running an emergency room with less than 25% of fees covered by insurers sounds impossible. Yet, as we have uncovered on our Wall of Shame, physicians often only see mere fractions of the cost of services rendered paid by insurers. Many providers assume that if these underpaid services weren’t followed up on within a few months, they are no longer recoverable. However, depending on the state you operate in and your revenue recovery strategy, there may still be a substantial opportunity to recover that revenue. Allia Group works with healthcare providers to pursue recovery on underpaid insurer obligations, in many jurisdictions, going back as far as ten years. Here’s what providers need to know in regards to how far they can go back in time to recover insurer underpayments. Why Do Old Insurer Underpayments Get Ignored? Underpayments rarely draw urgent attention. Most billing workflows prioritize newly denied claims or current high-dollar services. But underpaid A/R, especially billing from multiple years ago, falls through the cracks for a few key reasons: 1. Reviewing Aging A/R Is Time-Intensive Manual review of old records can overwhelm internal resources. Sorting, identifying, and assessing historical underpayments takes the right datasets and extensive time and staff allocation. Even in the largest teams, the work simply doesn’t get done. 2. IDR Deadlines Are Tight The NSA requires open negotiation and IDR submissions within 30-day windows. If providers miss those deadlines, they often assume the opportunity is gone. However, IDR is only one viable pathway to revenue recovery— individual litigation windows are significantly longer. 3. Litigation Feels Financially Out of Reach Not only are many billing teams unequipped to pursue litigation, hospital systems and physician groups regularly consider litigation financially unviable. In healthcare, even the largest organizations’ finance and legal executives tread carefully around litigation, agreeing it’s costly enough to warrant caution. The fear of unpredictable expenses makes health systems avoid taking legal action, even when it could be a powerful tool for financial recovery. 4. Early Attempts Hit Dead Ends Even when a billing company flags an issue or attempts an appeal, those efforts often stall early. Frequently, where there is no structured escalation process or follow-up strategy, valid underpayments remain unresolved. As a result, significant revenue gaps are created—even when payers clearly failed to meet their obligations by underpaying providers or violating contract terms. How Far Back in Time Can Healthcare Providers Go? The timeframe for recovery depends on the location of the hospital, physician group, or EMS company. Each state sets their own unique statute of limitations on Allia Group’s legal causes of action. This is the timeframe in which a provider can legally pursue recovery on underpaid services. The chart below lists the states with the longest statute of limitations: State Lookback Window Louisiana 10 years New Jersey 6 years Massachusetts 6 years Ohio 6 years Indiana 6 years Tennessee 6 years New York 6 years Kentucky 5 years Illinois 5 years Missouri 5 years Depending on the location of services rendered, providers may be able to pursue reimbursement for care delivered up to 10 years ago, even if they’ve written off the balance or closed the A/R in their system. What Types of Insurer Underpayments Can Be Recovered? A wide range of underpayment scenarios can qualify for litigation-based recovery strategies. Essentially, if a payer paid less than what was owed under a contract or applicable law, that shortfall can be pursued years after the fact. These common situations include: Downcoded services with no clinical justification Improper denial of emergency services or inpatient stays Out-of-network reimbursements manipulated through flawed repricing models Repeated contract violations or rate reductions outside negotiated terms Claims ineligible for IDR due to timing or batching constraints Systemic patterns of underpayment across CPT codes or service types Allia Group’s Difference Allia Group specializes in litigation finance and other tools which mobilize providers to recover revenue tied to old insurer underpayments. Our approach is different from traditional billing or legal services: 1. Sophisticated Data Analysis We apply proprietary algorithms and state-specific legal knowledge to identify recoverable balances. We examine historical billing records, payer behavior, and contractual terms to surface actionable opportunities. 2. Bundled Litigation Model We group underpaid claims across providers, service lines, and CPT codes to build large, compelling cases against payers. This strengthens negotiating power while reducing administrative burden. 3. Litigation Finance Allia covers the costs of pursuing recovery, including legal fees, expert witnesses, data prep, and court costs. 4. Revenue Realization Our model turns closed or aging A/R into new revenue streams. We’ve helped providers identify and recover millions in unpaid balances previously considered unrecoverable. Key Takeaways Many providers miss out on recoverable revenue tied to old A/R because they assume it’s no longer viable for recovery. In many states, providers can pursue legal recovery of underpayments going back up to 10 years. A wide range of underpayment types can be included in litigation-based revenue recovery, not just denied claims. Litigation can offer a broader, more flexible recovery pathway than IDR style arbitrations or appeals. Allia Group helps providers identify, bundle, and finance litigation-based recovery—unlocking millions in lost revenue.
