Key takeaways
- Work oldest and largest first — timely filing deadlines make the over-90 bucket a countdown clock.
- Every denial has a root cause upstream in verification, coding or attachments; fix the cause, not just the claim.
- Give claims follow-up a protected, recurring block with a named owner, or it will not happen.
- Track claims over 30 days and days in AR weekly, and the report stops rebuilding.
Nearly every practice we meet has an aging report they are slightly embarrassed by. It is rarely a competence problem. Claims follow-up is the only front-office task with no patient standing in front of it, no chair waiting on it, and no immediate consequence for skipping it today. So it gets skipped today, and then again tomorrow, and six months later there is real money sitting past 90 days.
Days 1–10: triage, do not chase
Do not start dialing. Start sorting. Export the full aging report and split it into buckets so you attack money in the order it is most likely to disappear.
| Bucket | Priority | Why |
|---|---|---|
| Over 90 days, high dollar | 1 | Timely filing deadlines are approaching or passed — this is the disappearing money |
| 61–90 days | 2 | Still recoverable, usually a denial nobody reworked |
| 31–60 days | 3 | Mostly needs a status call or a missing attachment |
| Under 30 days | 4 | Normal float — leave it alone |
Then check every claim over 90 days against the payer's timely filing limit and mark anything inside two weeks of the deadline as same-day work. Everything else waits.
Days 11–45: work the backlog and log root causes
As you rework each claim, record why it failed. This step is what separates a one-time cleanup from a permanent fix. In dental billing, nearly every denial traces to one of a short list of causes:
- Eligibility or coverage issue that verification would have caught
- Missing attachment — narrative, perio charting, radiographs, intraoral photos
- Frequency limitation or waiting period
- Coding issue, including downgrades and bundling
- Coordination of benefits not on file
- Claim never actually transmitted, or transmitted to the wrong payer ID
- Missing or expired pre-authorization
Practices that skip the tagging clear their aging report once and rebuild it within two quarters. Practices that tag stop seeing the same three denial reasons entirely.
Days 46–75: install a weekly rhythm
A backlog is cleared by a project. It is kept clear by a routine. The routine that works is boring on purpose:
- 1Daily: submit the day's claims with all attachments before close. Nothing carries overnight.
- 2Daily: post EOBs and ERAs the day they arrive, so the aging report reflects reality.
- 3Weekly, protected block: work every claim that crossed 30 days this week, oldest first.
- 4Weekly: rework every denial received that week — none may age.
- 5Weekly: report claims over 30 days, claims over 90 days, and days in AR to the owner.
- 6Monthly: review root-cause tags and change one upstream process.
If claims follow-up does not have a name and a recurring calendar block, it does not have an owner — and unowned work in a dental office always loses to whatever is happening at the front counter.
Days 76–90: patient balances, handled like a professional
Insurance AR is only half the report. Patient balances need their own ladder, and it should be consistent rather than aggressive: statement at 30 days, a friendly reminder call plus a text with a payment link at 45, a written notice with payment-plan options at 60, and a documented decision at 90 about payment arrangement or outside collections.
Most patient balances are not refusals. They are people who never got a clear number and never got an easy way to pay. Both are fixable in-house.
The four numbers to report every week
| Metric | Why it matters |
|---|---|
| Total AR and days in AR | The headline health of your collections |
| Percent of AR over 90 days | Money at real risk of never arriving |
| Claims submitted same day | Whether the leak is upstream |
| Denial rate and top three denial reasons | Whether you are fixing causes or just symptoms |
Ninety days of this is enough to change the shape of the report. The backlog clears because someone finally owned it, and it stays clear because the weekly block never moves and the root causes get fixed one at a time.
This work is also an ideal fit for a dedicated remote team member: it is queue-based, measurable, and it never competes with a patient standing at the counter.
Frequently asked questions
- How long does it take to clean up a dental aging report?
- A focused 90-day plan is realistic for most practices: about ten days of triage, five weeks working the backlog oldest and largest first while logging root causes, then a permanent weekly claims rhythm and a patient-balance ladder.
- Which dental claims should be worked first?
- Work claims over 90 days with the highest dollar value first, because timely filing deadlines make that bucket the money most likely to disappear permanently. Then 61–90 days, then 31–60.
- What are the most common dental insurance claim denials?
- Eligibility and coverage issues, missing attachments such as narratives or radiographs, frequency limitations and waiting periods, coding and downgrade issues, missing coordination of benefits, claims never transmitted, and missing pre-authorizations.
- What is a healthy days-in-AR for a dental practice?
- Practices generally aim to keep days in AR low and the share of receivables over 90 days small, tracked weekly alongside same-day claim submission and denial rate so problems are caught before they age.
