If you've been researching how to structure your therapy practice financially, you've probably encountered three terms used interchangeably — and inconsistently: cash pay, private pay, and out-of-network.
They're related but not the same thing. Confusing them leads to real problems: clients who think they can get reimbursed when they can't, therapists who don't realize they're leaving out-of-network revenue on the table, and marketing that speaks to the wrong audience.
Here's a clear breakdown of what each term actually means.
Cash Pay
Cash pay means the client pays you directly for each session, and no insurance claim is filed — ever. There is no insurance company involved in the transaction at any point.
Key characteristics:
- No insurance billing, no claims, no superbills
- The therapist never interacts with any insurer on the client's behalf
- The client cannot seek reimbursement from their insurance for these sessions
- Pricing is set entirely by the therapist
- Administratively the simplest model to operate
Cash pay is uncommon as a strict policy because it excludes clients who have out-of-network benefits they'd like to use. Most therapists who describe themselves as 'cash pay' actually mean private pay — they accept payment directly but may still provide superbills.
Private Pay
Private pay (also called self-pay) means the client pays the therapist directly, but a superbill may be provided so the client can seek out-of-network reimbursement from their own insurance company.
Key characteristics:
- Client pays the therapist's full fee at time of service
- Therapist is not contracted with any insurance company
- Therapist provides a superbill upon request — a receipt with CPT codes, diagnosis codes, and provider information
- Client submits the superbill to their insurer independently
- Insurer may reimburse the client a portion of the fee based on their out-of-network benefits
Private pay is the most common model for therapists who don't accept insurance. The therapist operates completely outside the insurance system but doesn't prevent clients from using their benefits — an important distinction that opens the door to clients with PPO plans.
Out-of-Network (OON)
Out-of-network is a designation from the client's insurance plan's perspective, not the therapist's. It means the therapist is not contracted with the client's insurance company, but the insurance plan still covers a portion of the cost.
Key characteristics:
- The therapist is not in-network with the insurer
- The client's plan has out-of-network mental health benefits (not all plans do — HMO plans typically don't)
- The client pays the therapist's full fee upfront
- The client submits a superbill and receives partial reimbursement from their insurer
- The reimbursement goes to the client, not the therapist
Out-of-network is technically a status relative to a specific insurance plan. A therapist who doesn't accept any insurance is out-of-network for every insurer — but not every client's plan will reimburse for out-of-network services. PPO plans commonly do. HMO and many Medicaid/Medicare plans typically do not.
How They Relate to Each Other
Think of it as a spectrum of insurance involvement:
- Fully in-network — contracted with the insurer, bill them directly, client pays only their copay/deductible
- Out-of-network with courtesy billing — not contracted, but you file claims on the client's behalf; client pays full fee, reimbursement goes to them
- Private pay with superbills — not contracted, don't file claims, but give clients documentation to file themselves; client pays full fee and handles their own reimbursement
- Cash pay (strict) — no insurance involvement whatsoever; client pays full fee, no superbill, no reimbursement path
Most therapists who describe themselves as private pay fall in the middle two categories.
Why This Matters for Your Marketing
The terminology you use in your marketing affects who contacts you — and who doesn't.
If your website says 'I do not accept insurance,' clients with PPO plans who have out-of-network benefits may assume they can't work with you and move on. That's a real loss. Many of those clients could afford your sessions at a fraction of the actual cost once their reimbursement comes through.
Tips
If your website says 'I'm a private pay practice. Many clients with PPO plans have out-of-network benefits that reimburse 40–70% of session fees. I provide superbills for reimbursement upon request' — you've just opened the door to a much larger pool of potential clients. No change to your rates or billing process required.
The Practical Takeaway
For most therapists building a private pay practice, the right model is: private pay with superbills available. You set your rate. Clients pay at time of service. You're not contracted with anyone. You provide superbills to clients who request them for their own out-of-network reimbursement. You have zero involvement with any insurance company's billing or claims process.
This gives you the administrative simplicity of cash pay while keeping the door open to clients with PPO out-of-network benefits — which in many markets represents a significant portion of your potential client pool.
Understanding the distinction between these terms isn't just semantic. It determines how you describe your practice, who you attract as clients, and how much unnecessary friction you create for potential clients who might otherwise work with you.
