The A/R Problem in Medical Billing
Accounts receivable is where medical practice revenue goes to die. Every claim that sits unpaid in an aging bucket is money the practice has already earned but not yet collected — and the longer it sits, the less likely it is to ever be recovered. For most practices, A/R management is an afterthought, something the billing team gets to when they have time between new claims and patient calls.
The result is predictable. Aging reports grow longer, denial follow-ups get delayed, and timely filing windows close silently in the background. By the time anyone notices the problem, thousands or tens of thousands of dollars have become permanently unrecoverable. This is not a billing error — it is a workflow failure that compounds every single month.
The practices that collect the most are not the ones that bill the most. They are the ones that systematically pursue every dollar already in their pipeline. A/R recovery is not a one-time cleanup project — it is an ongoing discipline that separates financially healthy practices from ones that are slowly bleeding revenue.
How Aging Claims Erode Revenue
The relationship between claim age and collectibility is not linear — it is a cliff. Claims in the 0 to 30 day aging bucket have a collectibility rate of approximately 95 percent. These are fresh claims where payers are still within their processing windows and all appeal options remain open. At this stage, the practice has maximum leverage.
Move to the 31 to 60 day bucket and collectibility drops to around 85 percent. Claims in the 61 to 90 day range fall to roughly 70 percent. Once a claim crosses the 90-day mark, collectibility drops below 50 percent — and for many payers, the timely filing deadline for appeals and corrected claims has already passed or is rapidly approaching.
These numbers mean that a $500 claim worth $475 at day 15 is worth only $250 at day 95. The service was rendered, the documentation was completed, and the claim was submitted — but because nobody followed up aggressively, half the revenue evaporated. Multiply that by hundreds of aging claims and the annual impact reaches six figures for even a mid-size practice.
Why 65% of Denials Never Get Reworked
Industry research consistently shows that approximately 65 percent of denied claims are never appealed or reworked. That statistic is staggering when you consider that the majority of denials are recoverable with proper follow-up. The money is not lost because it cannot be collected — it is lost because nobody tried.
The reasons are structural, not motivational. Most billing teams are understaffed relative to their claim volume. New claims take priority over denied claims because new claims have a clear path to revenue. Denied claims require investigation, payer calls, corrected submissions, and appeal letters — work that takes three to five times longer per claim than a clean first-pass submission. When the team is behind on new claims, denial follow-up gets pushed to next week, then next month, then never.
There is also a knowledge gap. Many billing staff do not know how to write an effective appeal letter, which supporting documentation to include, or what the payer-specific appeal deadlines are. Without that knowledge, denied claims feel like dead ends rather than recoverable revenue. The 65 percent number is not a reflection of bad employees — it is a reflection of inadequate systems and resources.
5 A/R Recovery Best Practices
Recovering revenue from aging A/R requires a structured approach. These five practices are what separate organizations that consistently collect above 95 percent of net revenue from those that leave money on the table every month.
1. Aging Bucket Prioritization
Not all aging claims deserve equal attention. Prioritize by a combination of dollar value and age. High-dollar claims approaching timely filing deadlines should be worked first because they represent the most revenue at the greatest risk of permanent loss. Build daily work queues sorted by this priority matrix rather than working claims in the order they appear on the aging report.
2. Root-Cause Denial Analysis
Every denial has a reason code. Track those codes, categorize them, and identify patterns. If 30 percent of your denials come from eligibility issues, the fix is at the front desk, not in the billing department. Root-cause analysis turns reactive denial management into proactive denial prevention. Review denial trends monthly and feed the findings back to the teams that can fix the upstream problems.
3. Payer-Specific Timelines
Every payer has different deadlines for claim submission, corrected claims, appeals, and reconsiderations. Maintain a payer-specific timeline matrix that your billing team references daily. Missing a timely filing deadline by even one day turns a recoverable claim into a permanent write-off. Automated alerts tied to payer deadlines are one of the highest-value investments a billing operation can make.
4. OON Claim Identification
Out-of-network claims that have been underpaid by payer vendors like Zelis, Multiplan, or Viant often sit in A/R aging reports disguised as paid claims. The payer sent a payment, but it was a fraction of the billed amount. Identifying these underpaid OON claims and routing them through a dedicated negotiation process can recover significant additional revenue from claims your team thought were already closed.
5. Weekly A/R Reporting
Monthly reporting is too slow for effective A/R management. By the time a monthly report reveals a problem, four more weeks of claims have entered the pipeline with the same issue. Weekly reporting on key metrics — total A/R, aging distribution, days in A/R, denial rate by category, and recovery rate — gives practice leadership the visibility to intervene before small problems become large ones.
The No-Win, No-Fee Approach
Many practices recognize they have an A/R problem but hesitate to bring in outside help because of the cost. Traditional RCM consulting engagements require upfront fees, monthly retainers, and long-term contracts — all before the practice sees any results. This creates a paradox where the practices that need help the most are the least able to afford it.
The no-win, no-fee model eliminates that barrier. Under this structure, the recovery partner works existing aged receivables and only earns a fee on revenue they successfully collect. If they recover nothing, the practice pays nothing. The incentives are perfectly aligned — the recovery team is motivated to collect as much as possible because their compensation depends on it.
This model is particularly effective for A/R recovery because aged claims represent money the practice has already written off or given up on. Any recovery above zero is pure upside. There is no risk, no upfront investment, and the practice gets to evaluate the partner's work quality on real results before committing to anything longer term.
REL1EF's A/R Recovery Trial
REL1EF offers a free A/R recovery trial built on the no-win, no-fee model. The process starts with a review of the practice's current aging report to identify the highest-value recovery opportunities. REL1EF then works those claims — filing appeals, contacting payers, reworking denials, and negotiating underpayments — at no upfront cost to the practice.
The trial serves two purposes. First, it recovers real revenue from claims the practice was not actively pursuing. Second, it demonstrates REL1EF's process, communication, and results quality so the practice can make an informed decision about ongoing engagement. Every claim worked during the trial includes full documentation of what was done, what was recovered, and why.
For practices sitting on aging A/R that nobody has time to work, the trial is the lowest-risk way to turn that dead inventory into collected revenue. The claims are already there. The money is already owed. It just needs someone with the time, expertise, and process discipline to go collect it.
