Key Takeaways

The average clinic fails to collect 8% of revenue it's legitimately owed — €40,000/year for a €500K practice

Always verify insurance before every appointment — coverage changes annually

Set automatic follow-up triggers: 14 days for unpaid claims, 30 days for rejections

Collect patient portions at booking time — waiting until after treatment creates friction and bad debt

The billing leakage problem

In our analysis of 200+ dental practices, the average clinic fails to collect 8% of revenue it's legitimately owed. Across a practice doing €500,000/year, that's €40,000 disappearing annually.

The causes are predictable and fixable.

Root cause 1: Incomplete insurance verification

The single biggest source of billing failure is treating patients without verifying their current coverage. Insurance changes every year. A patient covered last year may have a different plan today.

Fix: Verify insurance for every patient, every year — ideally before the appointment, automatically.

Root cause 2: Code errors and downcoding

Procedure coding errors — whether from inexperience, rushed billing, or outdated fee schedules — result in underpayment or outright rejection.

Common mistakes:

Using a comprehensive exam code when a periodic exam applies

Missing secondary codes that justify higher reimbursement

Submitting without required documentation (X-rays, perio charting)

Fix: Automate code suggestions based on treatment notes. Build in documentation checklists per procedure type.

Root cause 3: Slow follow-up on rejections

Insurance companies reject or underpay claims, then rely on practices not following up. Most rejections have a 90-day window to appeal — many practices let them expire.

Fix: Track every claim's status. Set automatic follow-up triggers at 14 days for unpaid claims, 30 days for rejections.

Root cause 4: Poor patient payment workflows

For the patient's portion, many clinics wait until after treatment to discuss payment. This creates friction and bad debt.

Fix: Collect estimated patient portions at the time of booking or on arrival. Offer payment plans for larger cases. Send invoices immediately — not weekly batch billing.

What good looks like

Practices with healthy billing operations maintain:

Clean claim rate > 95% (claims requiring no correction on first submission)

Rejection rate < 5%

Days in accounts receivable < 30

If your numbers are worse than this, billing optimisation is the highest-ROI project you can run this quarter.
