Few businesses have a wider gap between earning money and having money than a practice. You deliver care today; the payment may arrive thirty, sixty, or ninety days from now, and possibly not in full. A practice can be busy, well-regarded, and profitable on its income statement while the bank account tells a considerably more stressful story.
Understanding why comes down to one thing: the distance between the work and the money.
Where the money gets stuck
In most businesses the transaction is immediate. A customer buys, a customer pays. In a practice the path from delivered care to collected cash is long, and every step is a place where money can stall or disappear entirely.
- Registration — where insurance information is captured, or captured incorrectly.
- Eligibility verification — confirming coverage before the visit, which many practices skip and pay for afterward.
- Documentation and coding — where clinical work becomes billable, and small errors cause long delays.
- Claim submission — and everything that makes a claim unclean before it goes out.
- Payer adjudication — the insurer pays, partially pays, or denies.
- Patient balances — increasingly large, and far harder to collect after the visit is over.
Money can stall at every one of those points. That is why a practice can earn plenty and still feel broke.
The number to watch
If you track one metric here, make it days in accounts receivable: the average time between earning a dollar and collecting it. Healthy practices generally sit somewhere in the thirty to forty day range. When that figure climbs into the fifties and sixties, cash is getting trapped in the cycle and the practice will feel the squeeze even while revenue looks fine.
Rising days in A/R is one of the earliest and clearest signals that something is broken upstream — claims going out late, denials accumulating, patient balances aging. It behaves like a fever. It tells you there's a problem before you know what the problem is.
Denials: the quiet leak
Denied claims are where money vanishes most silently. A denial that never gets reworked is revenue you earned and gave away. Many practices carry denial rates well above what they'd guess, and a meaningful share are never resubmitted simply because nobody has the time.
The fix isn't dramatic. Track the rate, understand the top few causes — usually eligibility, coding, or missing authorization — and build a disciplined process to rework and resubmit. Practices that take this seriously routinely recover real money.
The half nobody planned for
High-deductible plans have shifted a growing share of the bill onto individuals, and individual balances are much harder to collect than payer payments. A practice built to collect from insurers can find that a substantial share of revenue now depends on collecting from people, often weeks after they've moved on. Collecting at the point of care, having the financial conversation up front, and following up promptly all matter more than they did five years ago.
And in cash-pay practices, the reverse
If you sell packages, memberships, or treatment series, your problem runs the other direction: the cash arrives before the work. That feels wonderful and creates its own trap, because a healthy bank balance made largely of undelivered obligations is not spendable money. Practices that don't record deferred revenue routinely mistake obligation for profit and spend it.
Why this is a bookkeeping problem
Here's the connection owners most often miss: you cannot manage a cash cycle you cannot see. If your books don't cleanly separate what was billed, what was collected, what's outstanding and how old it is, and what you still owe in undelivered care, you're flying blind.
Plenty of practices have accounting that satisfies the tax preparer and is useless for running the business. It describes last year. It doesn't show where your money is stuck right now.
The takeaway
A profitable-but-cash-strapped practice almost always has a cash-cycle problem rather than a profitability problem. The patients are coming, the care is good, the income statement looks healthy — and money is trapped somewhere in the pipeline between delivering and collecting, or already committed to work you've sold and not yet done.
Practices that solve this watch days in A/R, attack denials systematically, take patient collections seriously, record their deferred obligations honestly, and keep books clean enough to see where the money actually is. Fix the visibility first. The cash problems usually turn out to be fixable too.
Frequently asked.
Why is my practice profitable on paper but short on cash?
Because you earn revenue when you deliver care but may not collect for thirty, sixty, or ninety days — if in full at all. That gap between earning and having is the revenue cycle, and it's why a busy, profitable practice can still feel cash-stressed.
What is days in A/R and why does it matter?
Days in accounts receivable measures how long it takes to collect after delivering care. It's the single most telling revenue-cycle metric: when it climbs, cash tightens even if the practice is busy. Watching the trend catches problems early.
How do denials affect practice cash flow?
Denials are a quiet leak — claims that never get paid, or get delayed and reworked, draining both cash and staff time. Tracking and reducing them, alongside patient balance collection, is central to a healthy revenue cycle.
