Why unresolved work becomes aged A/R

An aging report shows how long a balance has remained open. Two accounts in the same 61–90-day bucket may require completely different actions, from a payer response to corrected billing, additional documentation, an appeal, or a decision from the provider.

The Healthcare Financial Management Association (HFMA) includes aged accounts receivable (A/R) among its core revenue-cycle measures. Its Measure, Apply, Perform (MAP) Keys group billed balances into 0-30, 31-60, 61-90, 91-120 and over-120-day categories to track aging and collectability. Net days in A/R provides another measure of overall receivables performance. HFMA

These measures become more actionable when the team can explain why each balance remains open. Age measures elapsed time; resolution depends on status, history, and the next action.

Age establishes priority. Status establishes direction.

An aging bucket establishes where to look first. The account history should show what the account is waiting for, what happened during the last meaningful action, and whether a correction, document, appeal, or internal decision is now required.

Consider three balances that are all 75 days old. One is still in payer processing, one was denied because documentation is missing, and one was paid below the expected reimbursement. They have the same age but need different follow-up.

Without that context, a reviewer may repeat earlier research while the balance remains in a queue without a defined path to resolution.

A touch is not the same as progress

Calls made, accounts checked, and notes entered show activity. They do not necessarily establish that an account moved closer to resolution. If “checked payer portal, still pending” appears repeatedly, the reviewer needs to determine what changed and what action is now available.

If a payer reports that medical records were not received, the next reviewer should not need to rediscover the problem. A useful note records:

• what the payer said,
• what is missing,
• who is responsible for providing it,
• when it was requested,
• what deadline applies,
• and when follow-up should occur.

The next reviewer can then start from the previous conclusion rather than reconstructing the account. The Centers for Medicare & Medicaid Services (CMS) claim-status standards illustrate why status information matters. Providers can use the Health Insurance Portability and Accountability Act (HIPAA) standard 276/277 transactions to ask health plans about a claim and receive an electronic response. CMS notes that electronic claim-status responses can be posted automatically to patient accounts, reducing manual entry and helping providers determine where a claim stands.

Research from the Council for Affordable Quality Healthcare (CAQH) shows how much administrative time claim-status work can consume when it remains manual. Its 2024 Index estimated that medical providers could save an average of 18 minutes per claim-status inquiry by moving to fully electronic transactions. It also estimated a $2.4 billion annual savings opportunity for the medical industry from broader electronic adoption. CAQH

An electronic status response can reduce manual research, but the reviewer still needs to determine whether the account requires action.

Time changes the risk of an unresolved account

Claim filing, corrected-claim, and appeal deadlines can limit what a provider can do while a balance remains open. The applicable period depends on the payer and the type of follow-up.

Medicare provides a clear example. CMS generally requires fee-for-service claims to be submitted no later than 12 months after the date of service. Claims filed after that deadline are denied for untimely filing, with limited exceptions. Centers for Medicare & Medicaid Services

An account nearing a filing or appeal deadline may need action before an older balance that is still within a documented payer processing period. If a clean claim is processing within that period, another call the next morning may add little; an outstanding document, incorrect payment, or expired processing timeframe may justify earlier follow-up.

The backlog can reveal a recurring issue

Denials add research, correction, documentation, appeals, and payer follow-up to the payment cycle. New exceptions can sustain a backlog even while staff resolve older accounts.

HFMA reported that initial claim denial rates reached nearly 12% in 2024 in Kodiak Solutions data. HFMA noted that higher denial rates slow cash flow and require health systems to spend additional resources pursuing payment. HFMA

Experian Health's 2025 State of Claims research found that 41% of survey respondents said at least one in ten claims was denied, while 54% said claim errors were increasing. Each denial introduces additional research, correction, documentation, appeal, or payer follow-up before the revenue can be resolved. Experian

Repeated balances with the same authorization problem, registration error, enrollment issue, missing document, or payer edit deserve a broader review. One account alone does not establish a recurring pattern.

In a hypothetical report, $1.2 million is over 90 days. If 28% of that over-90 balance is associated with the same payer issue, leadership can see both the size of the backlog and one condition contributing to it. The example is illustrative, not an Alico performance result.

The team can then resolve the existing balances while checking whether the same condition continues to create new receivables.

A/R reporting should explain more than the balance

Aging totals remain important, but leadership also needs to know why balances remain open, which accounts require action, which payer issues recur, and where a deadline or missing internal decision limits the next step. Combining those explanations with the financial measures turns the report into a useful view of unresolved accounts.

Age tells you how long the revenue has been open. The account history should tell you what has to happen next.
