Medical Billing A/R Over 90 Days Checklist

Use this checklist to turn an aging insurance report into a work queue. Check deadlines first, then give every open claim an owner, a next action, and a follow-up date.

Before You Work the Queue

  1. Pull the open insurance balances. Use the same aging basis across the report. Include payer and plan, balance, claim status, last action, and assigned owner. Reconcile posted payments and adjustments before prioritizing balances.
  2. Confirm the applicable deadline. Check the payer and plan rules for initial filing, corrected claims, reconsiderations, or appeals. Record the deadline, the event it runs from, and where you verified it. Escalate items with uncertain or approaching deadlines.
  3. Match the action to the claim status. For a clearinghouse rejection, correct the error and confirm payer acceptance. For a denial, review the remittance and determine whether the payer requires a correction, supporting records, or an appeal. For a pending claim, confirm receipt and ask what would move it forward.
  4. Assign each claim a next step. Record the action, owner, due date, and payer reference number when available. Sort claims with verified near-term deadlines first. Then consider balance, likelihood of resolution, and whether you have what you need to act.
  5. Review progress weekly. Track payments posted, balances still open, appeals awaiting a response, and recurring denial reasons. Share repeat issues with the team that can correct them.

Sample A/R Work Queue

These claims and deadlines are fictional. Use your payer’s actual rules and claim history when assigning priority.
