Membership Plans Are Replacing PPOs. Here's How to Set One Up.

The most expensive mistake in dentistry this year costs about $55,000 and it looks like a win. A practice launches a membership plan, 200 of its best fee-for-service patients enroll in the first ninety days, the front desk celebrates, and the owner has just written a permanent discount for people who were never going anywhere.

Here is the claim you can argue with: membership plans are not replacing PPOs, and they shouldn't. A membership plan is not a cheaper insurance company. It's the instrument that makes dropping a PPO survivable, and nothing more. Practices that treat it as a PPO substitute end up rebuilding the exact write-down they just escaped, except now they own the administration too. Our view: if you sell the plan to the wrong patients, it is worse than the contract you cancelled.

89% of the Market Is Still PPO, Which Is the Entire Opportunity

Start with the thing nobody wants to say out loud. The PPO is not dying. DPPO products held 89% of total commercial dental plan enrollment in 2024, unchanged from 2023, according to the National Association of Dental Plans. If you are waiting for employers to stop buying PPOs so your decision gets made for you, you will wait past retirement.

What is changing is tolerance. Per an ADA Health Policy Institute poll from late 2024, more than half of dentists named insurance-related issues as a top concern heading into 2025. That's not a trend. That's a majority of the profession identifying the same counterparty as its main problem while continuing to sign its contracts.

And the real market for a membership plan isn't the PPO patient at all. Among working-age adults, 63% have private dental benefits, 16% have public benefits, and 21% have no dental benefits at all, per the ADA Health Policy Institute. That last fifth is the plan's natural customer: no card, no maximum, no claim form, no reason to compare your plan to a Delta schedule. One in five working-age adults in your zip code has nothing, and most of them have decided dentistry is something you do when it hurts.

The $55,000 You Hand to Patients Who Weren't Leaving

This is the mistake, and it's almost always made by the owner who is most excited about the plan: enrolling existing fee-for-service patients.

Run it. Say your full fees are $110 for a prophy, $65 for a periodic exam, and $75 for bitewings. A patient on a standard two-cleanings-a-year preventive cycle pays $425 annually at full fee. You price your membership plan at $360 and include 15% off everything else. Every existing full-fee hygiene patient who enrolls costs you $65 in preventive revenue on day one.

Enroll 200 of them and you've given up $13,000 in preventive collections from patients who were already paying in full. Now add the 15%. If those 200 patients average $1,400 of restorative and elective work a year, the discount costs $210 each. That's another $42,000. Total: $55,000 of annual collections surrendered to a cohort with zero flight risk.

No new patients. No recovered cancellations. No reduced write-offs. Just a slightly nicer year for 200 people who liked you anyway, paid for out of the owner's distribution. For scale, the median annual wage for dentists was $176,110 in May 2025 per the Bureau of Labor Statistics, with employment projected to grow 6% from 2025 to 2035. That $55,000 is roughly a third of a dentist's median annual earnings, given away through a sign-up form.

We'd refuse to enroll a single existing fee-for-service patient in year one. Not as a soft policy. As an eligibility rule written into the plan documents: open to patients without dental benefits, and to patients whose plan you've just dropped. Everyone else keeps paying full fee, because they already do.

Price It Off Your Full Fee, Not Off Delta's

The second failure is quieter and worse. Owners price the membership plan by looking at their worst PPO and going slightly above it. That inverts the logic. You now have a permanent, self-administered fee schedule that lives near the bottom of your contracts, and you can never raise it without a mass renewal conversation.

Watch how fast it goes wrong. Suppose you load the plan: two cleanings, two exams, bitewings, fluoride, and 20% off all treatment, priced at $299 to look competitive. Full-fee value of the included services is $470 with fluoride at $45. That's a 36% write-down on preventive before a single crown. Plenty of PPO contracts write down 25% to 30%. You have just built a plan more aggressive than the insurer you were complaining about, and you are the one doing the billing.

Price the other direction. Start at full fee for the included services, discount 12% to 18% for prepayment and administrative simplicity, and stop. At $425 of included value, a $360 plan is a 15% discount, paid upfront, in full, with no claim, no attachment, no sixty-day lag, and no downgrade to an amalgam.

Then be stingy with the treatment discount. Ten to 15% off restorative is generous when the alternative for an uninsured patient is 100% out of pocket. Twenty-five percent off is you running an insurance company at a loss.

Dropping Plan C: 70% Is the Number That Decides It

Before the plan can replace anything, you need to know what leaving actually costs. That's the Break-Even Retention Test: the share of a plan's patients you must keep for collections to stay flat.

Say Plan C pays you $196 in net collections per visit after write-offs. Out of network, the same visit mix nets $280. Break-even retention is 196 divided by 280, or 70%. Keep more than 70% of those patients and dropping the plan makes you money. Keep less and you've bought yourself an expensive lesson in patient loyalty.

Make it real. You have 600 patients on Plan C averaging two visits a year. That's $235,200 of current collections. At the out-of-network rate you need 420 of them to stay to break even. Hold 480, or 80%, and you collect $268,800, a gain of $33,600 on 120 fewer patients and roughly 240 fewer appointments.

That freed chair time is the part owners forget to price. Two hundred and forty hygiene slots is most of a day a week. If you fill half of them with new patients at the out-of-network rate, that's another $33,600.

The gap between 70% and whatever you'd actually retain is the exact job of the membership plan. Nothing else.

The Plan's Only Job Is Covering the Retention Gap

Assume you'd naturally keep 60% of Plan C patients on goodwill alone, which is below break-even. You need another 10 points, or 60 patients, and you'd like a cushion.

Offer the membership plan exclusively to the 600 patients you're dropping, plus uninsured new patients. Enroll 300 at $360 and you collect $108,000 in prepaid, non-refundable, non-adjudicated revenue. Subtract the direct cost of delivering two hygiene visits (assume $62 per visit in loaded hygiene labor and supplies, so $124 a year) and you keep $236 per member. Across 300 members that's $70,800 of contribution.

Now the part that actually pays: membership patients buy treatment, because the money is already spent and the discount makes the next step feel earned. If 30% of those 300 members accept at least one restorative procedure averaging $980 net after a 15% discount, that's 90 cases and $88,200.

Add the breakage. Somewhere between 15% and 20% of members never come back for the second cleaning. At 18% of 300 members, that's 54 unused visits you were paid for, worth $3,348 in costs you don't incur. Nobody likes planning for breakage, but it's real and it belongs in the model.

Put it together: the plan contributes roughly $162,348 in year one against the $235,200 you were collecting from Plan C, while the 60% who stay without enrolling bring another $201,600. The plan isn't replacing the PPO's revenue. It's buying back the retention you needed and converting prepayment into treatment acceptance. That's a different business than insurance, and a better one.

Why You Probably Don't Need an Insurance License

The fear that stops most plans is regulatory, and it's usually misplaced if you keep the plan in-house. Most states regulate discount medical plan organizations but carve out the provider selling discounts to their own patients. South Carolina's statute is a clean example: Section 37-17-30(C) exempts a provider who offers discounts to his or her own patients from licensing as a discount medical plan organization.

Read that carefully, because the exemption has edges. It covers your own patients and your own services. The moment you market the plan to the general public as a product, include other practices in a network, or hire a third party to administer and sell it for a cut, you may be outside the carve-out and inside your state's insurance code. Statutes vary, so have a health care attorney in your state read your plan documents once, before you sell the first membership. One hour of legal review beats a cease-and-desist after 400 enrollments.

Two drafting rules regardless of state: never use the words insurance, coverage, benefits, or premium anywhere in your materials, and never promise anything unlimited. Say discount, membership, and fee.

What Kills These Plans in Year Two

Year one is easy; everybody signs up. Year two is where plans quietly die, and it's always one of four things.

• No renewal mechanism. If renewals require a phone call from someone at the front desk, your renewal rate will land near 55%. Card on file with auto-renew and a thirty-day notice email gets you to 80% or better. Build it before launch, not after.
• Perio patients on a prophy plan. Two cleanings a year does not describe a 4341 patient. Write a separate periodontal membership tier priced off maintenance fees, or your highest-need patients will consume the plan's entire margin.
• Family pricing invented on the fly. Decide the child tier and the additional-adult discount in writing on day one. Ad hoc family deals at the front desk are how a $360 plan becomes a $220 plan.
• No annual price increase. Raise the fee 3% to 5% every year on renewal, from the first renewal cycle. Owners who skip the first increase never take the second one either, and five years later they're running the cheapest fee schedule in the building.

One more thing we'd insist on: track membership patients as their own cohort in the practice management software from day one. Production per patient, treatment acceptance, recall completion, renewal rate. If you can't report those four numbers by cohort, you don't know whether the plan is working, and you'll defend it on feel.

Build the Plan This Week

Pull your net collections per visit for your worst PPO and run the Break-Even Retention Test on it; that single ratio tells you whether a membership plan is a growth product or a rescue. Price the plan at 12% to 18% off your full fee for two cleanings, two exams, and bitewings, with a 10% to 15% treatment discount and a separate perio tier. Write the eligibility rule that excludes existing fee-for-service patients, get a health care attorney in your state to read the documents, and set up auto-renew with a card on file before you sell a single membership. Then launch it to exactly one audience: the patients on the plan you're about to drop.

What would change our mind: a credible dataset showing membership patients hold recall completion above 80% for three consecutive years. If prepayment really does change behavior that durably, the plan stops being a retention patch and starts being the better product outright. We're watching renewal curves at the 24-month mark, because that's where the story gets told. Until then, treat the plan as a bridge, not a destination: the PPO sells your chair time wholesale, and a membership plan is you selling it retail, direct, and prepaid.

If you're sizing a PPO exit, the numbers above only matter against your own fee schedule and write-off percentages. Our free PPO-exit calculator computes your break-even retention by plan and shows how many membership enrollments it would take to cover the gap. Put in your net collections per visit and run your own numbers before you draft the termination letter.
