Word of Mouth, Done Right: Referral Programs and the Law
Referrals are the lifeblood of most membership practices, and outside medicine, referral rewards are a proven tactic. In healthcare, the same reward can run into kickback, patient brokering and FTC rules. Here is how to make sharing easy without paying for it.
Start here: the questions this brief answers
Tap a question for the short answer, then jump to the evidence.
Referred customers are valuable: in a large bank study, they were worth at least 16% more and were less likely to leave, and the bank's referral reward paid for itself. But a medical practice is not a bank. OIG says the federal kickback prohibition applies to all sources of referrals, even patients, and limits gifts to Medicare and Medicaid beneficiaries to nominal value. Several states have patient brokering laws that apply regardless of payer, and the FTC bars incentives tied to positive reviews. The safest referral program in medicine is one that pays nothing: an experience worth talking about, and simple tools that make it easy to share. Anything of value tied to referrals belongs in front of a healthcare attorney first.
“Patients who feel appreciated will always do more than is expected. You don't need to pay them to talk about you. You need to give them something worth talking about, and then make it easy.”
Can I give patients a free month for referring a friend?
Talk to a healthcare attorney first. OIG says kickback rules apply to all referral sources, even patients, and several state laws are not limited to government payers.
Go to the full answer ↓Do referral programs work?
Outside medicine, yes. In a bank study, referred customers were worth at least 16% more and the reward paid for itself. That doesn't make rewards legal in healthcare.
Go to the full answer ↓What can I do instead?
Make sharing easy without paying for it: share cards, open educational events, a simple "who else could we help?" conversation, and thank-you notes with nothing of value attached. Part 4 has ideas.
Go to the full answer ↓Can I reward patients for reviews?
Not with incentives tied to positive reviews; the FTC's 2024 rule bars them. See Brief No. 70.
Go to the full answer ↓Referrals work. Paying for them is the problem.
Ask most membership physicians how they grow and they’ll say word of mouth. In a 2019 CMT poll, 42% said referrals and word of mouth drove 76% to 100% of their new enrollments.1 Industry Research
Outside medicine, referral rewards are a proven tactic. In a Journal of Marketing study of about 10,000 bank customers, referred customers were worth at least 16% more and were about 18% less likely to leave. The bank’s 25-euro reward more than paid for itself.2 Population Data
So the natural next step is a referral program: a free month, a gift card, a discount for every friend who joins.
In healthcare, that’s exactly where you need to stop and call a lawyer.
Why a patient reward isn't just marketing
This section summarizes laws in general terms. It does not decide whether any program is lawful. Kickback and patient brokering laws carry criminal penalties and turn on facts and state law. Talk to a qualified healthcare attorney before offering anything of value connected to referrals.
OIG’s guide for physicians says the federal kickback prohibition “applies to all sources of referrals, even patients.” It also describes a separate law that imposes civil penalties on physicians who offer remuneration to Medicare and Medicaid beneficiaries.3 Policy and Law OIG has set “nominal value” for gifts to those beneficiaries at $15 per item and $75 per year in aggregate, and never cash or cash equivalents.4
Cash-pay doesn’t end the analysis. Florida’s patient brokering law makes it unlawful for “any person, including any health care provider or health care facility” to pay remuneration to induce patient referrals, and California’s law covers compensation “as compensation or inducement for referring patients” by licensed professionals, neither limited to government payers.5,
| Idea | Why to check with counsel first |
|---|---|
| A free month for each referred member | Something of value given in return for a referral |
| Gift cards for referrals | Cash equivalents; may exceed nominal value limits for Medicare and Medicaid beneficiaries |
| Discounts tied to referrals | Remuneration tied to referral volume |
| Paying a marketer per enrolled member | Per-patient payment is a common thread in kickback and brokering laws |
CMT summary of the cited sources; not a legal conclusion.3,
The same caution applies to reviews
The FTC’s rule on consumer reviews, effective October 21, 2024, bars offering incentives “in exchange for or conditioned on” reviews expressing a particular sentiment.7 Policy and Law A “leave us five stars and get a gift card” card at checkout is a problem twice over.
Make sharing easy, without paying for it
No More Waiting Rooms makes the case that word of mouth “doesn’t happen by accident.” It happens “because you did the reps,” through small deposits made consistently.8
Give them words
A simple share card that describes what members get, in plain language, with your phone number. Nothing of value attached.
Open the door
Host educational events open to the public, and let members bring a guest. (Check with counsel on refreshments and any giveaways.)
Ask a better question
“Who else in your life could use a doctor who answers the phone?” Ask it after a great moment, not at checkout.
Say thank you
A handwritten thank-you note when someone mentions you, with no gift and no strings (Brief No. 64).
CMT original ideas. Even no-cost programs should be reviewed by counsel. Evidence type: Practice Insight.
“I’ve found that the word-of-mouth aspect (vs. a billboard advertising approach) has been the most consistent factor in building my practice. I consistently have patients recommending their family members and friends… And the slow and steady approach ensures that staff can keep up with new patients.”
A concierge physician in the Midwest, quoted in Remark-ology (2025).9
A referral plan that pays nothing and earns a lot
Earn it
Fix the scenes patients complain about (Brief No. 61). Referrals follow experience.
Equip it
Create a share card and a one-sentence description your members can repeat (Brief No. 58).
Ask for it
Train clinicians and staff to ask the "who else" question after great moments.
Clear it
Before launching anything with a reward, send it to your healthcare attorney.
- Write your share card copy in plain language this week.
- List every referral reward you offer now, and send the list to your attorney.
- Practice the "who else could we help?" question in a huddle.

Referrals work
Referred customers are more valuable in other industries.
Rewards are risky
In healthcare, patients count as referral sources.
Make it easy
Words, events, questions and thanks, with nothing of value attached.
How this brief was built
This brief draws on a peer-reviewed referral program study (Journal of Marketing, 2011), HHS OIG physician guidance, a law firm summary of OIG's nominal value policy, state statutes in Florida and California, a law firm summary of the FTC's 2024 review rule, CMT's 2019 physician poll and CMT's books. It builds on Brief No. 51, The Referral Line. Statutes are summarized, not quoted in full. This brief is educational and does not decide whether any program is lawful.
How to read the evidence types
Every key finding is labeled by evidence type. Labels describe the type of evidence, not its value. Each type answers different questions. Funding is disclosed on every source.
Randomized trials and systematic reviews.Best for cause and effect.
Large observational studies and government data.Best for trends at scale.
Surveys, smaller studies and expert consensus.Best for real-world experience.
Company-sponsored or company-reported data that is not peer-reviewed.Best for early signals and operating data.
Statutes, regulation and official guidance.Best for what is required.
What we don't know
- How regulators would view specific non-cash referral thank-yous in a cash-pay membership practice; facts and state law decide.
- The actual value of a referred member in a membership practice.
