Module 6 · Payment Posting & Accounts Receivable
Lesson 4 of 5

Accounts Receivable Aging and Follow-Up

Accounts receivable (A/R) represents money still owed to the practice. Aging reports organize unpaid balances by how long they have been outstanding so teams can prioritize follow-up before deadlines or collectability problems grow.

Common aging buckets

BucketTypical interpretation
0-30 daysRecently billed; monitor normal payer processing and early exceptions.
31-60 daysReview unpaid claims, rejections, missing information and payer status.
61-90 daysEscalate unresolved claims and verify deadlines or documentation needs.
91-120 daysHigher collection risk; prioritize unresolved payer issues and appeal/follow-up limits.
120+ daysOld A/R requiring focused resolution, escalation and root-cause review.

Aging bucket definitions can vary by organization. The important point is to use a consistent aging method and not treat all balances equally.

Prioritize intelligently

Age matters, but so do dollar value, payer rules, filing/appeal deadlines, denial status, patient impact and the likelihood that action can resolve the account.

Follow-up workflow

  1. Review the account and previous notes.
  2. Confirm claim acceptance and adjudication status.
  3. Check payer portal or use the appropriate claim-status process.
  4. Identify the exact blocker.
  5. Take the supported next action.
  6. Record reference numbers, dates, deadline and next follow-up.
  7. Escalate recurring or high-risk issues.
Work the cause, not only the age. A 45-day claim with a near appeal deadline may be more urgent than a larger 60-day claim still within normal processing.

Quick knowledge check

What does an aging report organize?

Outstanding accounts receivable by the length of time the balance has remained unpaid.

Should A/R priority be based only on oldest balance?

No. Consider age, dollars, payer status, deadlines, denial reason and resolution potential.

What should every follow-up note include?

What was verified, action taken, reference/date information, deadline if relevant and the next step.
