What Is Aged Accounts Receivable?

Aged accounts receivable in healthcare is revenue that has already been billed but remains uncollected, sorted into time buckets, typically 30, 60, 90, 120, and 180-plus days past the date of service or claim submission. For a recovery firm, this aging report is the inventory. The older the bucket, the lower the probability of full collection and the higher the contingency rate a firm can command.

How the Aging Report Shapes Recovery Work

A hospital or physician group's aging report is produced by their practice management system or hospital information system. The report lists every outstanding claim with payer, charge amount, balance, and age. A $47,000 surgical claim at 94 days carries different recovery economics than a $900 office visit at 34 days.

Recovery firms do not buy this paper outright. They work on contingency, taking a percentage of what they collect, with the rate scaling by age. A firm might charge 8% on 60-to-90-day accounts and 18% on accounts over 180 days. The client keeps the remainder, which is revenue they had already written off or reserved against.

The work itself is claim-by-claim. An aged A/R specialist pulls the claim, identifies why it stalled, corrects the deficiency, and resubmits or appeals. The stall reasons are specific: a missing prior authorization number, a mismatch between the rendered procedure and the billed CPT code, a payer-specific timely filing limit that is approaching, or a denial code that the original billing staff never appealed.

The 90-Day Cliff

Most healthcare aging reports show a sharp drop in collection probability at 90 days. Commercial payers often apply their first denial or partial payment by then. Medicare claims denied for medical necessity enter the redetermination window at 120 days. Medicaid state plans vary, but many have hard filing deadlines at 180 or 365 days that kill the claim entirely if missed.

A recovery firm that takes 180-day accounts is often working against a statutory clock, not just a commercial one. The firm's value is knowing which deadlines are real and which are negotiable.

Why the Firm Owner Cares About A/R Age Buckets

The age distribution of a prospective client's aging report tells you what kind of recovery firm you are running. A book heavy in 60-to-90-day commercial accounts requires clean billing expertise and payer portal navigation. A book heavy in 180-plus-day Medicare denials requires appeals writers who understand the five levels of Medicare administrative review and can draft a qualified independent contractor brief.

Your contingency rate structure should reflect this. Younger accounts need lower rates to win the engagement. Older accounts justify higher rates but demand faster staff throughput because the claim may die before you collect.

The client conversation also changes by bucket. A CFO with 40% of A/R over 120 days has a liquidity problem. A revenue cycle director with 15% over 120 days but high denial volume has a process problem. The aged A/R report is the diagnostic tool for both.

Where Recovery Firms Misread the Aging Report

The most expensive mistake is treating the aging report as a cash projection rather than a recovery inventory. A $2.3 million 180-day bucket is not $2.3 million in recoverable value. It is a pool of claims with specific, individual barriers. Some are uncollectible because the patient has no coverage. Some are underpaid and need appeal. Some are billed to the wrong payer entirely. The firm that quotes a blended recovery rate without sampling the bucket first underprices the work or overpromises the client.

Another common error is ignoring the "last touch" date. A claim at 150 days may have been worked last week by the client's internal team, or it may have sat untouched since day 45. The aging report shows age from service date or submission date, not from last action. A recovery firm that prices based on calendar age without checking activity history will find the "old" claims are already appealed and denied, or already corrected and pending.

The Zero-Pay Trap

Claims that aged to 120 days with a zero payment and no denial code are often data entry failures. The claim never reached the payer. The recovery firm that treats these as denials to be appealed wastes time. The correct move is to verify electronic submission confirmation, check for clearinghouse rejections, and resubmit cleanly. This is lower-margin work but higher-volume, and some firms build their model on it.

Related Terms in Healthcare Recovery

Aged A/R sits at the center of several related concepts a practitioner should understand. Claim Denial is the formal payer rejection that often creates the aged A/R in the first place. Timely Filing Limit is the statutory or contractual deadline that makes age matter beyond mere probability. CARC / RARC Codes are the specific denial and remark codes that explain why a claim aged and what correction is required. Underpayment is the partial payment that leaves a balance aging, distinct from a zero-pay denial. Coordination of Benefits (COB) issues are a frequent cause of aged A/R when secondary payer billing is mishandled.
