The Insurance vs Cash Pay Binary Is a Trap: Why Physical Therapy Needs a Third Way
Walk into any room where PT clinic owners are talking strategy and you'll hear the same debate, framed the same way, every time.
Do we take insurance or go cash-pay?
It's treated like a binary. A fork in the road. Pick a lane and commit.
I understand why. Insurance reimbursement rates are being squeezed. Administrative burden is real. Cash-pay models feel cleaner, more profitable on paper, and they give clinicians more autonomy over how they practice. The argument for making the switch is seductive — and for some clinics, it's the right call.
But I think the framing itself is the problem. And the clinics that keep asking insurance or cash are already losing.
The Conversation We're Not Having
Here's what rarely gets asked: what else are we capable of building?
Physical therapists are among the most underutilized experts in the healthcare system. They understand movement, performance, injury prevention, biomechanics, aging, and recovery at a level that most other practitioners can't touch. And yet the dominant business model — insurance-based or cash-pay — treats that expertise as a single revenue-generating unit: the patient visit.
One patient, one hour, one billing code. Repeat.
The insurance-vs-cash debate is really just an argument about how to optimize that unit. It doesn't challenge the unit itself.
The more interesting question is: what happens when we stop optimizing the visit and start building around the expertise?
Why Insurance Still Matters
Before I go further, I want to be clear about something: insurance-based care is not a problem to be solved. It is a foundation.
At POST Physical Therapy — where I work as Director of Operations — insurance-based PT is the core of what we do. It allows us to serve a broad range of patients, stay connected to our community, and ground our practice in the fundamental work of rehabilitation. Most patients who need physical therapy don't have the option to simply pay out of pocket. An insurance-based practice is how you remain accessible.
The argument isn't against insurance. It's against treating insurance as a ceiling.
What "The Third Way" Actually Looks Like
The model I've been most interested in building is one that preserves the insurance foundation while layering something new on top of it — not cash-pay in the traditional sense, but something more intentional. I think of it as building around expertise rather than around billing codes.
What does that look like in practice? At POST, we've started calling them mini business units. Here's the premise:
Physical therapists have clinical interests. Real ones. A therapist who played competitive sports in college and now treats running injuries doesn't just want another ACL patient — they want to build something around running. A clinician who's obsessed with longevity research doesn't just want to treat Medicare patients — they want to develop a protocol that actually moves the needle on how people age.
The traditional model says: here's your caseload. The new model says: here's infrastructure. What do you want to build?
At POST, we've seen this produce programs like a running performance assessment that benchmarks athletes across two tiers of analysis, a longevity diagnostic lab co-led by two clinicians as a semi-autonomous unit with its own patient journey and retention model, a knee injury prevention program for young athletes designed and run by a visiting physiotherapist, and clinical performance testing for HYROX athletes that doesn't exist anywhere else at the clinical level in Boston.
None of these were top-down mandates. They came from therapists who had genuine expertise and the space to build with it.
Why This Matters for the Business
This isn't just philosophically interesting — it changes the economics.
When a practice has only one revenue stream (the visit), every business problem reduces to the same solution: see more patients. That creates utilization pressure, which creates burnout, which creates turnover, which creates the exact problem you were trying to solve.
When a practice has multiple revenue streams tied to genuine clinical programs, a few things happen:
Resilience improves. If insurance reimbursement drops for a CPT code, it doesn't crater the entire business model. The running assessment, the longevity lab, the performance testing program — those aren't dependent on the same payer dynamics.
Retention improves. Clinicians who are building something stay. Clinicians who are executing someone else's schedule leave. This is the most underrated benefit of the mini business unit model.
Referrals diversify. A running performance program gets referrals from running coaches, race directors, and sports medicine physicians — not just the standard PT referral pipeline. Each program creates its own network effect.
The brand differentiates. A clinic that offers insurance-based PT plus a physical performance index, a HYROX testing protocol, and a knee injury prevention camp is not competing on the same playing field as the clinic down the street. That's not positioning — it's actual competitive distance.
The Operator's Job Shifts
If you're running a clinic and you want to build this way, the challenge is real: you have to stop thinking like a practice manager and start thinking like a platform.
A platform creates infrastructure. It gives people the tools, the space, and the structure to build — and then benefits from what they create. That's a fundamentally different job than managing a schedule and hitting a utilization target.
At Sprout Ventures, much of my consulting work with PT clinic owners comes back to this shift. The financial systems, the team structures, the accountability frameworks — they all look different when the goal is supporting people who are building things rather than maximizing throughput of a single service type.
The skills required to manage that platform — operational design, performance tracking, talent development, program marketing — are not skills that PT programs teach. They're the skills I try to help clinic owners develop, because they're what the next phase of this industry actually demands.
Strategically Patient. Tactically Impatient.
A framework I've been sitting with lately, borrowed from something I heard on The Big Deal Podcast: be strategically patient and tactically impatient.
Strategically patient means not abandoning what's working. Insurance-based PT isn't broken. Don't blow up your foundation because the industry is having a panic about reimbursement rates.
Tactically impatient means not waiting to build. The clinician who has a genuine interest in longevity medicine, running performance, or injury prevention shouldn't wait for the industry to validate the model. Build the program now, refine it with real patients, and iterate.
The practices that will define what physical therapy looks like in ten years are not the ones that made the cleanest switch to cash-pay. They're the ones that built thoughtfully on top of a stable foundation — and gave their clinicians the space to create something new.
A Question Worth Sitting With
If your strongest clinician left tomorrow and started their own practice, what would they build?
If you already know the answer, the more important question is: why aren't they building it inside yours?
That gap — between what your clinicians are capable of and what your business model currently allows — is where the opportunity lives. It's not an insurance problem or a cash-pay problem. It's a structure problem.
And structure is something you can change.
