How to Reduce AR Aging: A Practical Framework for Hospital Revenue Cycle Teams

Reducing AR aging is an ongoing discipline, not a one-time project. It requires a combination of triage discipline, workflow structure, and consistent follow-up that sustains itself over time. Most hospitals have the capability to improve; the limiting factor is usually focus, not competence. This framework breaks the effort into manageable stages. 

Step 1: Build an Accurate Inventory Before You Work It 

Before triaging accounts, you need a complete and accurate picture of what you are dealing with. Pull a full ATB (aged trial balance) and reconcile it against your system of record. Flag any accounts that appear in your AR but have already been resolved — adjudicated, written off, or transferred. Working from a dirty inventory wastes follow-up effort and produces misleading performance data. 

Segment the inventory by payer, aging bucket, and balance size. This segmentation drives every prioritization decision that follows. 

Step 2: Prioritize by Recovery Probability, Not Balance Size 

The instinct is to chase the biggest dollars first, and that logic is not entirely wrong. The problem is it ignores collectability. A $50,000 claim that is 200 days old and approaching a timely filing deadline may be less recoverable than a $15,000 claim at 75 days with documented payer contact. Effective triage weighs three factors:

• Balance — higher dollar accounts generally warrant more intensive effort.

• Aging — accounts approaching timely filing windows or with escalating denial timelines need immediate attention.

• Payer behavior — some payers are systematically slow; others have specific escalation paths that produce results. Knowing the difference shapes your follow-up strategy.

One useful benchmark: HFMA guidelines recommend keeping AR over 90 days below 10% of total receivables. If you are above that threshold, accounts in the 91–120-day bucket deserve prioritization before you work deeper aging, because they still have meaningful recovery potential.

Step 3: Define Follow-Up Cadences by Payer Type 

The single biggest driver of AR aging is inconsistent follow-up. A claim that was filed correctly and denied for a correctable reason will age indefinitely if no one touches it again after the initial denial. Effective AR management enforces defined touchpoints: 

• Commercial payers — first follow-up within 10–14 business days of expected payment date; escalation at 30 days; supervisor contact or formal appeal at 45 days. 

• Medicare and Medicaid — follow-up tied to published payment timelines, with documentation of every payer interaction for audit purposes. 

• Medicare Advantage — these plans have become the most aggressive source of denials, with rates spiking 4.8% from 2023 to 2024, according to Kodiak Solutions. MA accounts warrant a separate, more intensive follow-up track. 

The cadence only works if it is enforced. Workflow tools that generate automatic next-action queues, rather than relying on individual billers to remember, are essential to consistent execution at scale. 

Step 4: Route to Specialists When Clinical or Coding Complexity Is Involved 

Not all unpaid claims are billing errors. Medical necessity denials, clinical validation disputes, and DRG downgrades require clinical or coding expertise to resolve. Routing these accounts through a generalist AR team without the appropriate specialist support wastes time and often produces suboptimal outcomes. 

Build a clear escalation path: identify the criteria that trigger referral to a nurse auditor, certified coder, or managed care specialist, and make that routing automatic rather than optional. 

Step 5: Resolution Is the Metric That Matters 

AR teams generate a lot of activity — calls made, notes posted, appeals filed. The metric that matters is resolution: accounts moved to a definitive outcome, either through payment or documented exhaustion of recovery options. Activity without resolution just means the account is being touched repeatedly without closing. 

Set resolution rate targets by aging bucket and review them weekly. Practices that conduct frequent performance reviews and apply structured follow-up cadences consistently tend to collect more per claim and carry less aged inventory over time. 

A Note on Sustaining the Gains 

Aged AR inventory tends to rebuild when the discipline that reduced it is relaxed. The most durable improvements come from embedding the triage framework and follow-up cadences into standard workflows, not just applying them during a recovery push. Organizations that treat AR management as an ongoing operational discipline, rather than a periodic cleanup, maintain tighter aging profiles and experience fewer write-offs over time. When current-period volumes make it difficult to sustain that discipline alongside a backlog recovery effort, separating the two — with dedicated resources for aged inventory — is often the fastest path to lasting improvement.

How Revecore Helps

The framework in this guide works. The harder challenge is sustaining it when current-period volumes compete for the same staff and attention. For health systems managing a significant backlog alongside ongoing operations, Revecore provides dedicated aged AR recovery resources — structured around exactly the triage and follow-up disciplines described here, with fees tied to cash collected.
