Your AR aging report is a billing error log. Are you reading it that way?
The accounts-receivable aging report is usually read as a collections list. Read as a diagnostic, it tells you exactly where the billing process is breaking.
What each bucket actually measures
0 to 30 days is normal processing. Most Medicaid and managed-care claims are still inside their adjudication window and nothing needs action. The one exception is a claim submitted more than 21 days ago with no adjudication activity at all, which usually means it never landed.
31 to 60 days is the working window, and it is where recovery is cheapest. For a Medicaid-heavy agency most of this bucket is simply collecting on schedule; the part that matters is the denied and untouched subset inside it. Those denials are still fresh, the appeal window is still wide open, and work done here is the cheapest work you will do.
61 to 90 days is where recovery on payer claims is still possible but appeal windows are closing. Appeal clocks commonly run 30 to 120 days from the remittance date and vary by payer and state, so a claim denied early in this bucket may have weeks left while one denied late may have days. Anything with a denied status here needs a decision this week. Private-pay invoices run on a different clock and should not be judged against this one.
90 plus each needs a specific status. A claim in this bucket without a note is a claim nobody is working. Anything that is truly dead gets written off cleanly so the report stays honest. In diligence and lending contexts, Medicaid claims older than about 180 days are usually treated as uncollectable regardless of what the AR report says.
Reading the distribution as a diagnostic
A growing 31 to 60 bucket points to a systematic denial from a recent change: a code, a modifier, a portal update, a new payer rule.
A 90 plus bucket that spans many payers points to an internal process problem, usually that nobody owns the denial queue.
A 90 plus bucket concentrated in one payer points to a payer-specific issue: an interface, a contract-load error, or a new pre-payment review.
A very large current bucket is not always healthy. It can mean claims are not going out at all.
Payer mix distorts the picture
Medicaid fee-for-service, managed-care Medicaid, and private pay adjudicate on different clocks. A 45-day-old private-pay invoice is normal; a 45-day-old Medicaid fee-for-service claim is a problem. Set an expected timeline per payer before you judge a bucket. The day ranges on this page are illustrative industry conventions, not Reeve results, and your own payer mix sets your real thresholds.
Unapplied payments inflate AR
When an electronic remittance fails to auto-post, cash you already received still shows as outstanding. Unapplied cash makes the aging report look worse than the business is, and it hides the real problem claims underneath. Post the remittances weekly and reconcile unapplied cash monthly.
The weekly 20-minute AR review
Three checks. What moved into 31 to 60 this week and why. What is about to age out of an appeal window in the next two weeks. What is sitting in current too long, meaning submitted more than 21 days ago with no adjudication activity.
Plain answers, on the record.
Collect is money you never captured. Cover is money a payer can still take back.
Reeve reports the two separately and never adds them together, because only one of them is yours to go and get. The Margin Review reads both on your own export and costs nothing.

The recovery lane. Care you delivered and never billed, units short of what was authorized, lines paid under the published rate.
Everything in Collect, plus the exposure lane. Retired codes, authorizations at the end of their period, care delivered past what was approved.

The Margin Review pulls the recoverable dollars out of your aging buckets by reason: unbilled, denied and unworked, lapsed authorization, and rate mismatch.
