Why your A/R is sitting past 90 days

When a practice calls us, the number that usually starts the conversation is the same: a big chunk of accounts receivable sitting past 90 days. The owner assumes something dramatic went wrong. Almost always, it didn't. Four ordinary things went unattended at the same time.

1. Nobody owns the aging report

Front desk teams are measured on the schedule, not on collections. If working the insurance aging report isn't explicitly someone's job on a specific day, it becomes nobody's job. The report doesn't get worse dramatically — it gets worse quietly, one week at a time.

2. Claims went out incomplete

A claim missing a narrative, a perio chart, or an x-ray doesn't get denied immediately. It sits. Then it gets rejected. Then it sits again while someone figures out what was missing. Catching attachments before submission is the single highest-leverage habit in dental billing.

3. Denials never became appeals

Most denials are appealable, and a meaningful share of appeals succeed. But appeals take time and confidence, and a busy front desk has neither. So the denial gets written off, or worse, quietly forgotten.

4. Patient balances were never explained

Patients don't refuse to pay nearly as often as they fail to understand what they owe and why. A clear explanation at the time of service prevents most of the collection calls that come later.

What to do this week

Pull your insurance aging report and sort it by age, oldest first. Take the ten oldest claims. For each one, write down a single word: missing, denied, no response, or patient. That five-minute exercise will tell you which of the four problems is actually yours — and the fix is different for each.
