Most dental practices have an AR problem they don't fully see.

Not because they're not looking — but because the numbers on the AR aging report are accepted as fixed, when they're actually a signal. High AR days, a bloated 90+ bucket, a climbing denial rate: these aren't just administrative annoyances. They're revenue sitting outside your bank account.

The DSI AR & Collections Analyzer helps you quantify exactly how much, and benchmark it against peer practices.

Understanding Your AR Aging Report

The AR aging report is the most important financial report most dental practices don't review with enough rigor. It tells you:

How much money is owed to you in total
How long it's been outstanding (0–30, 31–60, 61–90, 90+ days)
Whether your collections process is working or leaking

AR Days Outstanding

AR days outstanding = total AR ÷ average daily net production.

This tells you how many days of production are sitting uncollected at any given moment.

Benchmark data: | Percentile | AR Days | |---|---| | P10 (best) | 15 days | | P25 | 22 days | | P50 (median) | 35 days | | P75 | 52 days | | P90 | 72+ days |

A well-run practice should target under 30 days. Between 30 and 45 days is acceptable. Above 50 days means your collections process has a structural problem — usually in insurance follow-up, patient balance collection, or both.

The 90+ Day Bucket: Where Revenue Goes to Die

AR over 90 days — what percentage of your total AR is aged beyond 90 days — is the single most diagnostic number in your AR report.

Benchmark data: | Percentile | AR Over 90 Days | |---|---| | P10 (best) | 2% | | P25 | 6% | | P50 (median) | 15% | | P75 | 28% | | P90 | 40%+ |

Industry research consistently shows that AR aged beyond 90 days has a collection probability of roughly 40% or less. By 120 days, you're looking at 25–30% collectibility. This means a practice with $150,000 in AR and 35% in the 90+ bucket has approximately $52,500 sitting in the 90+ category — of which only about $21,000 is realistically collectible.

The AR & Collections Analyzer calculates this cash recovery estimate for your actual AR balance.

Collections Rate: The Denominator That Changes Everything

Collections rate = net collections ÷ net production.

The target is 97–101%. Consistently below 95% is a red flag. Here's what commonly causes it:

Low collections rate causes:

Uncollected patient balances — Patients leaving without paying their portion, balances not pursued
Insurance write-offs beyond contractual — Writing off balances that weren't actually contractual adjustments
Delayed insurance collections — Claims not followed up on, denials not resubmitted
Bad debt — Accounts sent to collections that reduce net collections without reducing production

A 3-percentage-point improvement in collections rate on a $2M practice is $60,000 in annual revenue. It's the fastest path to more money that most practices aren't taking.

Claim Denial Rate and Days to Payment

Two metrics most practices track loosely but rarely benchmark:

Claim denial rate (first-submission denials ÷ total claims submitted):

Best-practice target: below 6%
National median: ~10%
Above 15%: systemic coding, documentation, or eligibility problem

Days to insurance payment:

P50: ~28 days from submission to payment
P75: ~38 days
P90: 55+ days

If you're averaging 45+ days to insurance payment, check: Are claims being submitted within 24–48 hours of service? Are your attachments complete on the first submission? Are denials being worked within 5 business days?

The Revenue Recovery Estimate

The most actionable output of the AR & Collections Analyzer is the cash recovery estimate: what portion of your 90+ day AR bucket is realistically still collectible, and what would it take to collect it.

This is the number that convinces practice owners and DSO operators that AR management deserves dedicated staff time — or a revenue cycle management partner.

A rough rule of thumb: 40% of your 90+ day AR balance is potentially recoverable with aggressive follow-up. The analyzer shows this calculation with your actual numbers.

Common Questions

How often should I review my AR aging report? Weekly for practices under $1.5M in collections; twice weekly for larger practices. The AR aging report is a leading indicator — by the time a problem is obvious, it's already been developing for 60–90 days.

Should AR include patient balances and insurance AR separately? Yes, and most modern PMS systems separate them. Insurance AR and patient AR have different collection characteristics and different processes. The 90+ bucket breakdown by type (insurance vs. patient) is more actionable than the combined number.

What's the right benchmark comparison for a multi-location DSO? At the location level, the same benchmarks apply. At the enterprise level, AR days should actually improve with scale because of dedicated RCM staff and centralized billing. DSOs running above 40 AR days at scale have a centralization problem.

What's a realistic goal for my denial rate if I'm currently at 18%? Below 10% within 90 days is achievable for most practices through better pre-authorization processes, improved clinical documentation for narratives, and faster resubmission of denied claims. Below 6% typically requires either a dedicated biller or an RCM service with claims scrubbing.
