Can a Cash-Pay Practice See Medicaid Patients?

In most states, yes: a Medicaid patient can see you and pay cash, but only if you are not enrolled as a provider with that state's Medicaid program and the patient signs a private-pay agreement before the first visit. Enrolled providers face the opposite rule. Under federal regulation 42 CFR 447.15, Medicaid's payment plus any copay is payment in full for covered services, and charging cash instead of, or on top of, that payment is the violation that cost a Massachusetts psychiatrist $42,425. Every question in this area comes back to that enrollment distinction, plus your state's specific rules for the non-enrolled path.

This is practice-operations guidance and no substitute for legal or medical advice. Medicaid is state-administered and private-pay rules vary widely; confirm your state's rule with its Medicaid provider manual, your attorney, or your malpractice carrier before relying on it.

Does enrollment status decide whether a Medicaid patient can pay cash?

Yes, almost entirely. 42 CFR 447.15 requires state Medicaid programs to limit participation "to providers who accept, as payment in full, the amounts paid by the agency plus any deductible, coinsurance or copayment required by the plan." If you are enrolled with a state's Medicaid program, that rule attaches to every covered service you furnish to a Medicaid enrollee there: the program's payment plus any patient cost-sharing is the entire fee, and a cash charge in place of it is a compliance violation with restitution and penalties attached. If you never enrolled, the federal rule has nothing to attach to, and the question moves to state law, which usually permits a private-pay arrangement with paperwork.

"Establish two facts before you quote a fee: does this patient have Medicaid in any form, and is your name in that state's Medicaid provider file," says David Cohen, CPA, JD, who reviewed this guide. "Every enforcement action I have read in this area started with a provider who was in the program and behaved as if a cash arrangement took them out of it."

What happened in the $42,000 Massachusetts case?

An enrolled MassHealth psychiatrist charged cash for a covered service, and the state treated it as an enforcement matter. In June 2020, the Massachusetts Attorney General announced that a Cohasset psychiatrist would pay $42,425 to resolve allegations that he charged patients cash fees for Suboxone treatment MassHealth already covered, with more than half of the settlement returned to patients as restitution. The press release states the operative rule plainly: MassHealth providers must accept the program's payments as payment in full for covered substance-use treatment.

The case circulates in private-practice forums as proof that a cash practice can never see a Medicaid patient. The enforcement history shows a narrower pattern. The same office had already collected $150,000 from a Norfolk practice over cash Suboxone charges, and in January 2019 a Dorchester physician pleaded guilty over the same conduct, drew house arrest, and surrendered his medical license. Every action targeted providers inside the program charging cash for covered services, and all of them involved addiction treatment, a fraud-unit priority in most states. The trap is being enrolled and taking cash anyway.

Can you see Medicaid patients if you never enrolled?

In most states, yes, as private-pay patients who agree in writing before care starts. The payment-in-full rule is a condition of participating in the program, so a practice that never enrolled sits outside it, and most state manuals permit a non-enrolled clinician to treat a Medicaid enrollee privately when the patient is told the provider is outside the program and consents to pay. Verify your own state before treating that as permission: a minority of states restrict the arrangement further, whether by extending payment-in-full logic beyond enrolled providers, limiting it for specific service categories, or mandating state-specific forms and conditions. Read the billing-members or private-pay section of the state's Medicaid provider manual, and if it is silent, get an answer from the state's provider line in writing.

Medicaid has no opt-out, which trips up clinicians coming from the Medicare side. Medicare's affidavit-and-private-contract process (how opting out of Medicare works) has no Medicaid equivalent; there is no affidavit to file and no formal opted-out status to hold. Each state program simply treats you as enrolled or as a non-participating outsider, and the outsider rules are whatever that state wrote.

What must a Medicaid private-pay agreement say?

At minimum: that you are not a Medicaid provider, that the patient knowingly chooses private care anyway, and what it will cost, all in writing before the first billable service. The recurring elements across state rules:

• Signed and dated before any billable service. A retroactive agreement protects nobody.
• A plain statement of your status: you are not enrolled with the state's Medicaid program, you will not bill Medicaid, and Medicaid will not reimburse the patient for your fees. There is no out-of-network claim pathway for the patient to file, so do not hand these patients a superbill as consolation.
• An informed-choice acknowledgment: the same or similar services may be available at no cost from a Medicaid-enrolled provider, and the patient chooses private care anyway.
• The specific services and fees covered, with a time bound. Washington's Apple Health rule (WAC 182-502-0160) shows how prescriptive a state can get: billing a client requires the agency's own Agreement to Pay for Healthcare Services form (HCA 13-879), signed before the service, listing each service, the covered alternatives, and the dollar total, with the service date falling within 90 days of signing. Where your state publishes a form, use the state's form.
• A renewal habit. Re-sign when your fees change, and annually as good hygiene.

The No Surprises Act adds a wrinkle rather than an obligation here. The good-faith-estimate rule defines a self-pay individual (45 CFR 149.610) to exclude anyone who has benefits for the service under a federal health care program, and its choose-to-self-pay clause lists commercial coverage only. Read plainly, a Medicaid enrollee paying privately for a covered service falls outside the GFE mandate, while a service their Medicaid does not cover puts them back inside it. Write the estimate for every private-pay patient anyway: the agreement above already contains the numbers, and one uniform workflow beats sorting patients by coverage type.

How do you screen for Medicaid at intake?

Ask directly, because patients often do not volunteer it. Add one line to your intake forms and your screening call: "Do you have Medicaid, a state health plan, or any government coverage, including as secondary insurance?" Three traps make the direct question necessary:

• Managed-care cards look commercial. 78% of Medicaid enrollees were in risk-based managed-care plans as of July 2024, and the cards carry brand names like UnitedHealthcare Community Plan or Molina Healthcare. A patient reading their card to you over the phone may sincerely believe they hold commercial insurance.
• Secondary Medicaid hides behind a primary plan. A patient with employer coverage plus Medicaid as secondary is still a Medicaid enrollee for these rules.
• Dual eligibles bring Medicare rules too. A patient with both Medicare and Medicaid layers Medicare's separate opt-out requirements on top of the state Medicaid analysis. Two compliance regimes, one patient.

Document the answer either way. If the patient is a Medicaid enrollee and your state permits private pay, the signed agreement goes in the chart before the first visit, next to the intake packet.

Does Medicaid managed care change the analysis?

It adds a protective layer for the patient. Federal rule 42 CFR 438.106 forbids holding a managed-care enrollee liable for more than they would owe if the plan had covered the service directly, so a network provider cannot use a cash arrangement to escape the plan's rates any more than an enrolled fee-for-service provider can escape 447.15. If you contract with a Medicaid MCO, that participation agreement governs, and going cash-pay means terminating it on its own notice terms first. If you hold no Medicaid enrollment and no MCO contract, the private-pay analysis runs the same as fee-for-service, with one practical catch: some states route their rules through the plans, so the manual's answer may direct you to the patient's specific MCO for the final word.

Is it ethical to see Medicaid patients as cash-pay?

Both directions of this argument are honest, so the ethics live in disclosure and genuine choice. The Massachusetts AG's framing is the case against: charging cash for care a patient is entitled to at no cost puts a barrier in front of that care, and with addiction treatment the barrier can be lethal. The access argument is the case in favor: in many markets, few psychiatrists accept Medicaid and enrolled clinics carry long waitlists, so a patient who cannot find an open in-network panel may reasonably prefer paying your fee to months of waiting. Most states' private-pay rules exist precisely so that choice stays legal.

If you take these patients, the ethical floor looks like this: tell them plainly, before money moves, that enrolled providers would cost them nothing, and offer two or three names; treat the signed agreement as the record of that conversation rather than a substitute for it; and think honestly about whether your standard fee is the right ask for this patient or whether a reduced one is. If the broader economics of an insurance-free panel are still an open question for you, start with insurance vs. cash-pay and come back to the Medicaid subset once the model is settled.
