In most businesses, you sell something and get paid. In healthcare, you deliver care, submit a claim to a third party, wait, collect part of it, appeal the rest, and eventually chase the balance from the patient months later. The gap between "care delivered" and "cash in the bank" is where a lot of otherwise-healthy practices quietly starve. And the most dangerous idea in the whole conversation is the one everyone repeats: 90 days in AR is just normal for our specialty.
It isn't normal. It's expensive. And it is usually fixable.
Receivables are a loan you didn't agree to make
Every dollar sitting in accounts receivable is a dollar you have already spent — on payroll, rent, supplies — but haven't collected. You are financing the payer's slow payment out of your own cash. The longer that balance sits, the more working capital the business must hold just to keep the lights on. Growth makes it worse rather than better: more volume means more receivables, which means more of your own cash tied up in claims you have delivered but not yet been paid for.
The metrics that tell the truth
You cannot manage what you don't measure honestly. Three numbers do most of the work:
- Days in AR — total receivables divided by average daily charges. A useful compass for the overall trend, though not a target in itself.
- Aging buckets — 0–30, 31–60, 61–90, and 90-plus days. The oldest bucket is the danger zone: collectibility falls sharply the longer a claim ages. To illustrate the shape of the problem rather than to quote a benchmark, a claim that is straightforward to collect at 30 days can become a coin flip once it drifts past 120.
- Denial rate and net collection rate — how many claims are rejected on first pass, and what share of collectible revenue you actually collect. A practice can post "normal" days in AR and still leak money through denials it never reworks.
Building this view reliably is a reporting problem first — the aging has to be clean and segmented by payer before it can be acted on, which connects directly to how your payer mix behaves.
Notice what the specialty-norm excuse quietly does: it turns a controllable operational result into an immutable fact of life. Two practices in the same specialty, billing the same payers, routinely post very different receivables performance — and the difference is process, not fate. That is why the right target is not an industry average but your own best achievable number: the days in AR you would reach if every claim went out clean, every denial was worked promptly, and every patient balance was pursued on a set schedule. Measured against that internal benchmark, the gap between where you are and where you could be stops being a shrug and becomes a concrete, fundable opportunity.
Why AR balloons: the front door and the back office
Most receivables problems are born before a claim is ever submitted. Front-end causes — eligibility not verified, missing prior authorizations, coding errors, incomplete documentation — produce denials that were entirely avoidable. Back-end causes are about follow-through: denials that sit unworked, no systematic cadence for chasing aging claims, and write-offs taken by default rather than by decision. The fix is mostly discipline, not heroics.
A framework to attack it
Freeing the cash trapped in receivables comes down to a handful of moves, run consistently:
- Measure the aging honestly, by payer. Averages hide the problem; segmentation reveals which payers and which stages are actually slow.
- Fix the front door. The clean-claim rate is the single highest-leverage number — a claim that goes out correctly the first time collects far faster than one that bounces.
- Work denials like revenue, because they are. A denial is rarely a final no; it is a "not yet — resubmit correctly." Unworked denials are money left on the table.
- Set a follow-up cadence and hold to it. Aging receivables are a use-it-or-lose-it asset; the value decays with time.
- Manage patient balances deliberately. As plans push more cost onto patients, the portion you collect directly grows — and it behaves nothing like a payer balance.
The cash payoff
Shaving time off the collection cycle produces two wins at once: a one-time cash windfall as the backlog clears, and a permanent reduction in the working capital the business must carry. To illustrate the magnitude rather than promise a result: pulling the average collection time from roughly 75 days down toward 50 would free a meaningful slice of the receivables balance as cash — real money that can fund a hire or pay down a line of credit, without adding a single patient. Your own numbers will differ, but the mechanism is universal.
Receivables management is not glamorous work, and it is easy to shrug and say "that's just how our payers are." But the aging report is the difference between a profitable practice and a profitable practice that is always short on cash. A dedicated CFO or controller treats that report as a live cash document, reviewed and acted on every month — because 90 days is not a norm to accept. It is a target to beat.
