Most practice management systems break accounts receivable into aging “buckets,” typically 0–30, 31–60, 61–90, and 90+ days. On its own, a dollar figure in each bucket doesn’t say much. What matters is the shape of the report: where the balance is concentrated, and whether it’s moving toward resolution or just getting older.
What each bucket is actually telling you
- ✓
0–30 days. Normal, healthy AR: claims recently submitted and still working through the payer’s adjudication process. A high balance here isn’t a warning sign by itself.
- ✓
31–60 days. Claims that should be getting resolved. A growing balance in this bucket often means claims are stalling somewhere: pending status, missing information requests, or early-stage denials not yet worked.
- ✓
61–90 days. Claims that need active investigation, not just a routine follow-up call. At this age, something has usually gone wrong and hasn’t been caught yet.
- ✓
90+ days. The highest-risk bucket. The longer a claim sits here, the more likely it approaches a timely filing or appeal deadline, and the harder it becomes to collect at all, especially from patients whose memory of the visit has faded.
The shape matters more than the total
Two practices can have the same total AR balance and be in very different positions. A balance concentrated in the 0–30 day bucket is simply claims in normal transit. The same total concentrated in the 90+ day bucket is a practice with a backlog that’s actively losing value the longer it sits. Reading the report means looking at where the weight is, not just the bottom-line number.
When to intervene
As a general rule, a growing 61–90 day bucket is the earliest clear signal that follow-up isn’t keeping pace with submissions. It’s usually easier to fix at that stage than to wait until balances have pushed into 90+. Once a claim crosses into the 90+ bucket, it needs to be triaged by dollar value and payer, since not everything sitting there is equally worth the effort to chase, and appeal or timely-filing deadlines may already be close.
What a healthy AR process looks like
- ✓
Most of the balance sits in the 0–30 day bucket, reflecting claims still in normal processing
- ✓
Claims are worked on a defined schedule by age, not just when someone has spare time
- ✓
High-dollar claims are prioritized regardless of age, since they carry the most risk if missed
- ✓
The aging report is reviewed regularly enough to catch a bucket trending the wrong way before it becomes a backlog
