Cash pay medical practice: models, rules, and setup

A cash pay medical practice collects payment directly from patients for visits or services instead of submitting those claims to a health plan. It can charge by visit or offer a defined membership. Before choosing this model, decide what patients buy, how you explain the price, and how Medicare rules, existing payer contracts, and good faith estimates apply to the care you plan to provide.

Should you choose cash pay, insurance, or both?

Choose the model around your patients, services, and operating plan. A cash-pay practice needs a clear offer and payment process. Insurance billing requires the plan's enrollment and claims workflow. A mixed practice must make the payment path clear for each service and patient. An insurance contract may limit when you can collect a cash price for a covered service.

Model	What to plan	Question to settle before launch
Cash pay	Prices, estimates, payment timing, refunds, and patient explanations	What is included, and what will the patient pay elsewhere?
Insurance	Enrollment, covered services, claims, denials, and patient balances	Which plans and services are confirmed, and from what effective date?
Both	Separate workflows with a clear explanation before the visit	Which payment path is permitted by the relevant contract and law?

Have healthcare counsel review the plan before advertising that all patients can pay cash. In particular, Medicare opt-out is a formal status, not another name for a self-pay visit. This guide is general information; federal sources were checked October 12, 2026.

What changes if a patient has Medicare?

A Medicare beneficiary cannot simply be treated like every other cash-pay patient for an otherwise covered service. Opt-out requires compliant private contracts and an affidavit filed with the appropriate Medicare Administrative Contractors. Nonparticipating status is different from opting out. Confirm your status and the service's treatment under Medicare before setting the patient's payment process. 42 CFR Part 405, Subpart D

The regulation generally uses two-year opt-out periods that renew unless properly canceled. Participating physicians have quarter-based timing requirements; nonparticipating physicians and other eligible practitioners have a different filing path. Opt-out obligations apply across otherwise covered services, with specific emergency and urgent-care rules. Review the full process with the contractor and counsel, including effects on any other work you do. Medicare private-contract rules

Write down three separate answers: your enrollment or opt-out status, whether the planned service is covered, and which patient agreement and billing rules apply. Do not use a generic cash-pay consent as a substitute for that review.

When do you need to give a good faith estimate?

Federal rules require good faith estimates for eligible uninsured or self-pay patients when they request one or schedule qualifying care. The definition can include someone with insurance who is not seeking a claim to that coverage. Government program coverage needs separate attention under the regulation's definition. 45 CFR 149.610

CMS explains the scheduling deadlines this way:

Trigger	Deadline for the estimate
Care scheduled 3 to 9 business days ahead	Within 1 business day of scheduling
Care scheduled 10 or more business days ahead	Within 3 business days of scheduling
Estimate requested before scheduling	Within 3 business days of the request

Source: CMS good faith estimate guide, checked October 12, 2026. CMS also explains that appointments scheduled 0 to 2 business days ahead do not trigger the same scheduling entitlement.

Build the estimate into intake. Record whether a patient will use insurance, recognize cost inquiries as estimate requests where the rule applies, send the written estimate, and retain it. A price on the website helps set expectations, but the estimate has its own required information. 45 CFR 149.610

Is a cash pay medical practice the same as direct primary care?

No. Cash pay describes who pays for a service. Direct primary care (DPC) is a practice and payment model with periodic payments for a defined set of primary care services. A cash-pay specialist charging for individual visits is not necessarily a DPC practice. A membership also needs a written definition of what is included and excluded. AAFP DPC policy

Payment arrangement	What the patient buys	What to explain
Per-visit payment	A named visit or service	Visit length, follow-up, testing, and any separate charges
DPC membership	Defined primary care services over a period	Included care, access expectations, exclusions, and cancellation
Other membership	The particular services in that agreement	Whether visits or other care are billed separately

AAFP notes that DPC patients may still carry insurance for services outside the practice, such as hospitalization and specialty care. Explain that boundary clearly. For a DPC launch, use the direct primary care practice guide.

How do you explain the price to patients?

Describe what the fee buys in ordinary language before the patient commits. A patient should be able to tell whether the price includes the visit, messages afterward, follow-up appointments, lab collection, outside lab charges, or medication. Avoid promising reimbursement from an insurer when the practice cannot determine the patient's benefits or claim outcome.

Use this review checklist for each offer:

• Service: What happens at the appointment, and what is outside its scope?
• Price: What is due, when, and to whom?
• Other bills: Which labs, pharmacies, specialists, or facilities bill separately?
• Follow-up: What is included, for how long, and how are additional visits charged?
• Changes: What are the cancellation, refund, and membership-ending terms?
• Insurance: Will a claim be submitted, and what has been confirmed about the payment path?

Test the explanation with someone unfamiliar with the practice. Ask them to describe what they would pay for the first visit and a follow-up. Any mismatch is a place to clarify the offer.

What should you have ready before accepting payment?

Prepare the clinical, payment, and administrative workflows together. Verify licensure and coverage, resolve Medicare and payer-contract questions, put estimates and patient agreements in place, and decide who handles refunds or billing questions. Use the startup budget to plan operating cash rather than assuming direct payment removes every collection risk.
