Nothing kills a practice faster than accepting insurance.
I know, because that’s what drove me to bankruptcy.
This isn’t the version of the story I usually lead with, and it’s not the version most physicians want to hear. The version most physicians want to hear is that there’s a sustainable middle path — accept some insurance, opt out of Medicare, contract selectively, balance the cash side and the contracted side, ride two horses for as long as it works. I tried that path. It didn’t work.
What follows is the structural argument for why that path doesn’t work for almost any independent physician, the four ways insurance specifically destroys an independent practice, and the case for treating cash-pay not as an experimental concept but as the only sustainable model for a private practice in 2026.
What insurance actually does to your business
When you sign a contract to accept a payer — commercial, Medicare, Medicaid, anything — you agree to four things, whether you read the contract or not.
1. You agree to take whatever they give you. The payer sets the rate. You don’t negotiate, except cosmetically. You don’t price for your value, your training, your differentiation, or your quality of care. You’re paid the same as the doctor across town who runs an entirely different kind of practice. The contract levels the playing field — but it levels it in a direction that punishes excellence. There is no premium for being better. There is no discount for being worse. Your business is structurally prohibited from being differentiated on price.
2. You agree to wait to be paid. The bill goes to the payer. The payer takes 30 to 90 days to adjudicate. The bill comes back partially paid, fully denied, or paid at a different code than you submitted. You appeal. The appeal takes weeks. Eventually, somewhere down the line, you might get fifty cents on the dollar, three months after you delivered the care. Meanwhile, your rent was due on the first. Your staff was paid on the fifteenth. Your supplies arrived COD. The payer’s cash flow problem becomes your cash flow problem, and you have nowhere to push it.
3. You agree to play their compliance game. Every payer has its own coding rules, documentation requirements, prior authorization thresholds, audit risk, and appeal procedures. Multiply that by the number of payers you contract with and you have a regulatory burden that makes large-system administrators full-time jobs and that makes solo practice owners insane. You can hire staff to manage it; you cannot escape it. The complexity is the point — it transfers the cost of the system’s friction onto your back.
4. You agree to keep the liability. This is the one most physicians don’t fully understand until it bites them. When the payer audits you and decides three years’ worth of claims were miscoded, you owe the money back. When the documentation doesn’t hold up, you’re the one in front of the medical board. When Medicare flags your billing pattern as an outlier, you’re the one explaining yourself. Your billing service can’t take that liability. Your CPA can’t. Your attorney can’t. The contract is in your name, and so is the exposure.
Take any one of these in isolation and an independent practice can survive it. Take all four together and you have the operating environment that made me, and a lot of physicians like me, financially insolvent. It’s not a moral failing or a business-acumen failing. It’s the structure.
The cash flow death spiral
Of the four, the cash flow problem is what actually kills practices.
Run the math. You see 25 patients a day, you bill out $200 average. That’s $5,000 a day in gross billing, $1,250,000 a year on paper. In reality, you’ll collect somewhere between $600,000 and $750,000 of that — about 50 to 60 cents on the dollar after contractual write-offs, denials, no-pays, and bad debt — and you’ll collect it 60 to 120 days after you delivered the service.
Meanwhile, you have to fund the practice every two weeks. Payroll doesn’t wait. Rent doesn’t wait. Supplies don’t wait. Malpractice doesn’t wait. So you’re constantly carrying 60 to 90 days of accounts receivable on a line of credit, paying interest on the gap between when you do the work and when the payer pays you.
When something disrupts that cash flow — a payer changes contract terms, a denial wave hits, an audit pulls back six months of receivables, a software glitch delays submissions — the practice doesn’t have months of runway. It has weeks. And you find out, the way I did, that an independent practice running on insurance reimbursement is one bad quarter away from a crisis you cannot cash-flow your way out of.
Why your advisors can’t save you
When the trouble starts, every physician’s first move is the right one: get help. CPA. Attorney. Practice management consultant. Billing company.
What I learned, painfully, is that none of them can save you from the structural problem. They can optimize within it. They can tighten coding, accelerate collections, fight specific denials, restructure debt. They can’t change that you’re underwater on the math the contract dictates. The advisors are working at the operational layer. The problem is at the structural layer.
By the time you understand this, the runway is gone. Bankruptcy isn’t usually the result of a bad decision. It’s the result of a structurally bad model that ran out of time before the owner realized what they were operating inside.
The David-and-Goliath problem
Here’s the part nobody tells independent physicians.
The insurance reimbursement system was not built to support independent practices. It was built around — and increasingly, for — the large systems. The hospitals, the academic centers, the integrated delivery networks have negotiating power, government subsidies, marketing budgets in the eight figures, and balance sheets that can absorb 90-day collection cycles without flinching. They can run insurance-based primary care at near-zero margin or even at a loss because they make their money on the downstream — admissions, surgeries, specialty referrals, ancillaries.
You can’t. You don’t have those subsidies. You don’t have those margins. You don’t have those balance sheets. When you accept insurance, you’re being asked to compete in a game whose rules were written by and for institutions that are economically and structurally nothing like you. It is the worst version of David-and-Goliath in American business — except David doesn’t get a sling, and the rules of the fight require him to play by Goliath’s terms.
This is not solvable by being smarter, working harder, or hiring better. The asymmetry is structural. You either play the game and lose, or you find a different game.
The different game
The different game is cash-pay.
For the physician, the math is decisively better. Recurring revenue from membership. 90%+ gross margins. No contracts you didn’t choose. No 90-day receivables. No payer compliance. No audit risk. No write-offs. The dollar a patient pays today is in your account today. The financial picture I covered in The Real P&L of an Insurance-Free Practice is what this looks like in steady state — owner take-home approximately twice what employed primary care earns, on similar revenue, with control over every variable.
For the patient, the surprise is that cash-pay is often cheaper than insurance, not more expensive. Patients spending $400 to $700 a month on premiums plus copays and deductibles are paying $5,000 to $8,000+ a year for a system that gives them seven-minute visits, restricted networks, and refusal to cover the testing that would actually help them. A $275/month cash-pay membership is $3,300 a year and includes 60-minute visits, direct access to the physician, and the diagnostics insurance won’t pay for. The patient pays less and gets more.
The reason this seems counterintuitive is that the system has trained patients (and physicians) to think of insurance as the thing that makes care affordable. In a fee-for-service environment, insurance pays providers and the patient is shielded from the actual cost. In cash-pay, the patient pays directly — and the cost is much lower because every layer of administrative friction the insurance system creates is gone. No billers. No coders. No claims department. No prior-authorization queues. No appeal processes. No denied claims. The savings from removing those layers go to the patient.
What about my patients?
This is the hardest objection, and the one most independent physicians wrestle with longest.
The honest answer: when you go cash-pay, some of your existing patients won’t follow. The ones whose financial situation truly can’t support the model will go elsewhere. That’s real, and it should be grieved. It also doesn’t mean what most physicians fear it means.
Most patients can afford a cash-pay practice if they understand what they’re getting. The patients who can’t are usually the ones served best by community health centers, federally qualified health centers, and free clinics that exist specifically for that population. A cash-pay practice can absorb some uninsured or underinsured patients through sliding scale, charity care, or scholarship slots — and many do. The model isn’t elitist; it’s structurally honest about what it can sustainably serve.
The deeper answer is: a practice that goes bankrupt serves nobody. The physicians who collapse trying to be all things to all patients on insurance reimbursement aren’t taking care of anyone in the long run — they’re closing their doors. The physicians who run sustainable cash-pay practices serve the patients they have, support charitable work for those they can’t, and stay in business long enough to compound their impact. The math works only one of those ways.
The long game
I’m writing this years past my own bankruptcy, in a practice and a business that wouldn’t exist if I hadn’t been forced to learn the structural lesson the hardest possible way. The version of me back then would have given anything for someone to say what I’m saying now: stop trying to make the insurance model work. It’s not your fault that it doesn’t work. It was never going to work.
Going cash-pay isn’t a marketing tactic, a niche play, or a luxury. For most independent physicians, it’s the only sustainable structure. The insurance system can survive without you. Your practice cannot survive inside it.
If you’re staring at your AR aging report wondering how you’re going to make payroll, and your billing company is on the phone explaining why this month’s collections are down again, and you’re thinking maybe you just need to grind harder for a few more quarters until things stabilize — please hear me. They’re not going to stabilize. The structure won’t let them.
The long game isn’t tightening up your insurance practice. It’s getting out.
